last year I repot my H.henryi and I cut some roots, like I take rootcuttings from my Anemones I try it with the roots from the Hepaticas, I put them in a sandy compost and now a year later I have some nice new plants, I dont no if it will work with H.japonica but I will try it this year.
dit anyone try this also?
-
I forgot the photos, I try it with the first 3

Chris I have never tried it, but I certainly will now, as you have such excellent results, well done!
-
sorry some problems with uploading pics, here the next two
-
That's very interesting.
-
I do agree Martin ! very interesting :D
-
Hi Chris
I would like to try some root cuttings of Hepaticas did you lay them flat on the soil ? Some more information would be a help to me. Thank you.
Angie :)
-
I haven't tried root cuttings as such but I once did have some new little shoots come up about 4 months after I had dug out a large plant. They can only have been from roots shooting.
-
Chris
Thank you very much for the hopeful information and illustrated report!
I join to angie's question. Did you lay root or dig them vertically? Did you cut roots at the caudex or use outlying roots?
-
I put the roots in 10cm pots vertically, about 10 for 1 pot, when I pot them up I lay my pot horizontaly so in fact I lay my roots flat, when I set my pot vertically I fill the pot with compost 1cm above the roots, than I water them in and just wait, never let dry the pot out
-
Chris I always feel a bit silly asking these things but I think it's worth it if I can learn something that will help me. :)
Thanks for you help.
Angie :)
-
A great find Chris !!! :o
-
Chris
Thank you very much for the hopeful information and illustrated report!
Did you cut roots at the caudex or use outlying roots?
That would be my question too.... ??? Looks like outlying roots, but can't be sure.
-
I assumed from Chris's remarks and photos that these were root trimmings cut off the ends at re-potting time and which would previously have been discarded, which makes this a very useful propagation technique.
-
That was my first thought, but when Olga asked the question I was in doubt..... it is a very excting prospect for increase, that's for sure.
When Chris finished his birthday cake- many happy returns of the day, Chris - he'll let us know, I'm sure.
-
thanks Maggi, Martin you're right, H.heryi makes a lot of roots and while I was repotting some fell off, so I tried to make cuttings from them and these where the results, this week I will try it with some Japanese and also with H.nobilis.
I have tried it in autum but than it failled, I think in autum you have root growing and in spring you have the start of new shoots.
I take also my anemone cuttings in spring, in the nursery where I worked we always take root cuttings in spring and important NO fertiliser at all,
other questions for tommorow, I'm out for the rest of the day
-
Chris thank you again for very useful and detailed report! I'll try to do the same with my nobilis, transilvanica and others!
Maggy :)
-
Very interesting, Chris. This is something I must try. Thanks for showing us.
-
Edit - my apologies, I posted in the wrong thread. Have moved the post to Hepatica 2011
-
I read somewhere that root cuttngs were a possible technique for raising new plants and that the cuttings should be as stout as possible.I have tried it several times with japonicas but without success.There seems little point with others as they produce plenty of seed.
-
I have since located the source of advice and it is contained in the publication by the NIGATA NURSERIES ASOCIATION of JAPAN. which accompanied their wonderful exhibit in association with Ashwood Nurseries at the RHS's flower show in London on the 15th.Feb.2000,and in my opinion never since surpassed by any other exhibit.They state and I quote verbatum:-
< PROPAGATION >
THERE ARE THREE METHODS OF PROPAGATION PRACTISED
1. Division This is generally done when repotting in Spring or Autumn.
2. Cuttings When potting in Autumn,a mature subterraneum stem is cut into several pieces and inserted into compost.
After one month new leaves emerge from the nodes.
3. Seed Seeds ripen approxiametely 40 days after pollination.These are sown as soon as ripe(in April)normally on sand.
They must not be allowed to dry out.
I
would add that I sow in the same compost that I grow in and that I have tried taking root cuttings on several occassions without any success
-
Hello, fellow Hepatica forumists.
This is my very first comment and I am so excited!
I am a transplanted Japanese living just outside of Detroit, Michigan, since early 80's. Japanese gardening books, magazines on growing wildflowers, etc., that I have read mention propagation with root cuttings to be one of the commonly used methods for H. Japonica. However, I have not had any success myself and really interested to hear others experiences.
By the way, February is the month for annual Hepatica shows by Hepatica associations both in Niigata and Tokyo, in Japan. If you happen to be in Japan, you must check it out!!
-
Welcome KK, the rich growing area around Ann Arbor seems to be a good place to be "transplanted" to and we hope that you might like to "put a few roots down" here, too............ ;) sorry, cannot resist a little joke! :-[ (and yes, folks, I know, that was a very little joke)
-
What a very interesting idea - I'll certainly be having a go. Thank you for your experience, Chris.
-
Chris, thanks for the magnificent message. Fine illustrations!
To make multiple copies such method I did not try.
I make multiple copies Hepatica other method - implanting a kidney with a small piece of a stalk (whether I do not know correctly I name?) and about 1-2 leaves during the period right after flowerings and to the middle of June.
This way has appeared successful for Hepatica nobilis, Hepatica asiatica and Hepatica henryi.
-
Natalia, although your English is excellent, 'implanting a kidney' is not clear to me. Please could you describe this a little more?
-
Anne, I beg your pardon, I am not strong in botanical terminology in English. I am only familiar chemical terms :D
For clarity, here is this photo:
Photo 1 - Hepatica cuttings remaining from the division of rhizomes
Photo 2 - cuttings were planted in the ground, then on top - a small greenhouse.
Photo 3 - the first flowering plants from the kidney, the second spring after division.
-
No need for apology :D- now I understand. I sometimes have pieces without roots when I divide. It is good to know they can grow into new plants.
-
Anne, this way stable and tested, it is good to implant a kidney with a rhizome part, but that thin roots are capable to germinate - I did not know.
Many thanks to Chris for a magnificent illustration of this way!
-
Fascinating!! Absolutely fascinating!! Thanks all.

Greetings from KK-Ann Arbor, who is visiting Japan now. I left snow-covered Michigan on the 24 th, the temperature in teens F, and here I am in a spring like Tokyo, in 60s F!
Just love all recent photos of Hepaticas shared on the forum recently!! My hepatics are still getting ready to go in action in Michigan in April. They are currently covered under the snow, as we have had a few big snow storms within the past couple of weeks.
I am here in Japan to check out the annual Hepatica show in Tokyo sponsored by the Hepatica Association of Japan. This is a 2-day event and over a dozen vendors and breeders are showing their plants including new creations, vying for awards. I understand that some have been or will be introduced as registered new flowers for 2011. The show is just very nice with lovely plants. I am drooling over each and every plant, but I can only bring 12 of them back home with me. Decisions, decisions...
I wanted to share rooting information I found in the back issues of wild flower magazines I bought at the show. Sorry it is not from my own experience, but thought these tips supports postings by Chris and Natalia.
Root cutting:
When dividing a mature plant, break off the main root of the mother plant leaving the top 1-2 cm with the new divided plant.
Apply benomyl solution to the part of the root broken off and pot the root in upright position, covering all parts with compost.
Making a new plant from a leaf – tips from a Hepatica enthusiast experimenting propagation using hormones and accelerating growth with gibberellin:
In August-September, break off one of the newly developed leaf of the season from the base of the plant. Pot the leaf after dipping the base of the leaf in a solution of rooting hormone for 20+ hrs.
Photos showing this process started with leaves looking just like the ones shown in the first photo posted by Natalia.
I am looking forward to try these methods this year with my fingers crossed for success.
-
KK, firstly congratulations for being able to visit this hepatica show , while escaping from your winter weather in Maine.... sems like a great move!
secondly many thanks for sharing these tips with us.... extremely useful info to help us in our experiments. Thanks!
Good luck with narrowing down your choice to twelve..... not an easy task. :-X
-
The 12 plant limit is set by the U.S. authorities.
Now, we have no such limit in Canada. :D :D I am sure you could
find foster parents for your plants just over the border, and you could pop north
to visit.
-
Nice try, Diane! ;D
-
Diane,
Only if I had known, I would have looked up for a Canadian foster parent.
As it stands now, I will have to leave about 10 plants at my son’s condo here until the next time I get over here. My husband was supposed to follow me a day late. However, because of the weather in Detroit area and additional happenings, he could not make it. Bad news is, I already placed my order for 22 plants out of 24 allowances for myself and my husband. Alas, now I am forced to pick 12 out of 22 I have. Only 10 of them are hepatics. Epimediums, Jeffersonia and anemonella thalictroides make up the rest. Not only I missed out on selecting my 2 remaining Hepatics at the show to come home with me, I have to leave some with my unfortunately ‘not very interested in plants’ son.
I am a beginning Hepatica enthusiast with a long list of failures spanning years. I only buy inexpensive Hepatics for beginners around Y800 in strong colors. I splurged on a lovely yellow one for Y3,500, this time, though.
-
That much for a yellow :o, we pay that for fairly ordinary hepaticas in the UK. You must post a picture of your treasure.
-
Anne
What I paid for the basic yellow seemed to be the base price for yellows at that show. Since I could not add any more plants, I did not really investigate retail tables and I might have missed those on sale prices.
I am not very good at taking photos, and posting, I am not sure. But I will try, once I get home without problem through Narita and Detroit inspection processes. My husband had the connection cable to load photos to the computer :(
-

Wow, at that price, it's almost worth the air fare to Japan! Maybe we ought to orgainse an SRGC trip for next year - we would soon clear their sales tables. :D
-
KK, thanks for the information on reproduction by sheet - I will try!
Some years ago heard a mention of such method, but did not know about use gibberellin. Now there are more exact data, will experiment!
Good luck in a choice 12...
Waiting for photo. :)
-
Natalia,
The example referenced in my earlier posting regarding gibberellin, also mentioned the use of gibberellin starting on the seeds before germination to encourage a stronger growth, not just accelerating the process. In one extreme example, he observed 10 growing nodes (?) in one seed just 1 year after germination. He uses cyctokinin as well in his experiment. I am not familiar with this and no details are given related to its use. He notes that when using growth hormones, you need good light to promote photosynthesis. However, he also cautions that when under this accelerated process, everything gets accelerated including attacks from red spider mites!
I made the decision and bringing 10 hepatics and 2 Japanese Jeffersonias (Lavendar Twin Leaves) home with me.
-
KK, I understand that the leaf is used for breeding solution cyctokinin, and gibberellin - at sowing seeds.
Thanks for the illumination and red spider mites.
Good luck with the chosen hepatics and Japanese Jeffersonias!
-
KK you just gotta show us your plants!!!!!
Any pictures of the show itself?
Mike
-
Sorry, I was busy clearing the stacked up work while I was having a great time in Japan.
I have some photos, quality of which are questionable.
Will anyone be kind enough to direct me to where I can find the direction on how to post a photo? Certainly be quicker than for me to go looking.

I have much to learn about taking phtos.
You will see the selection to be heavily tilted to my likings.
-
I can see how it would be very difficult to choose just a few KK. Did you have any photos of the plates behind the plants? I think they look beautiful too.
I too have a not-very-interested-in-plants son. What burderns we have to carry. :D
-
I love them all Anne, absolutely stunning plants!!
Thank you so much for sharing.
We tend to remove the old leaves for flowering, however the Japanese way of keeping the old leaves with the new flowers looks good.
-
KK - What a great show it must be! Like Lesley, I'm curious and interested in the plates behind the plants. Maybe when you have some time you can explain how it works.
-
Here is a better photo of the trophy plate.
The higher the award level, the bigger the plate!!
-
The white unnamed one would be my first choice ;D Thanks for sharing your pics ;)
-
KK, I think you are quite entitled to slant the pictures to those that took your eye!
I am sure I am not alone in being VERY grateful to havethe chance to see these plants at a Japanese show and winning their wonderful plates!
Ian and I both chose the gorgeous yellow Kirameki (gold medal winner)- what a stunner it is. 8)
We are extrememly fortunate to have your report on this Hepatica show from Japan, via Ann Arbor! Thank you!
-
And aren't the plates a wonderful prize! Do they get to keep them or return annually (she says, lusting after one ;D)
-
I am with Maggie and Ian,I haven't been attracted to the yellows before because they all seem wishy-washy but this one takes the buiscuit for me,Thanks for showing.
-
Me too, and the very dark-centred blue. I wonder how they keep the leaves in such good condition?
-
I believe that if your entry wins the award, you get to keep the plate. They are made specifically for this purpose. I must confess that when I first saw those trophy plates a few years ago, I just wished that they would offer them for purchase.
Those plants exhibited on the show floor were just tremendous. Conversations carried out between the vendors and experienced enthusiasts on the retail floors below were just beyond my comprehension, talking about what's hot, special characteristics they achieved, exchanging hybridization tips, etc.
Imagine the time and efforts that go into creating those flowers! No wonder some plants are priced so high!!
I am happy with just about anything blooming. Hoping for my new Hepaticas to recover from the shock they had to endure. Also looking forward to the weather to warm up and see my plain acutilobas and americanas to bloom in a month or so.
In the meantime, I am thouroughly enjoying photos of treasures posted by other forumist.
kk
-
Wow, imagine getting to keep those plates! No wonder you go over to the show, there is so much to see. And I'm totally intrigued by the yellow flowered one.....
-
I'm with you Chris. Just imagine a whole set of them, father, mother, several babies. ;D
-
;D
-
Ann, you all right?
-
KK, doing a bit of catching up, love your pictures, thanks for taking the time to show us these delights.
I have nothing special but love them all the same.
Angie :)
-
Chris, I thank!
At me it has turned out - on a photo - small young plants turned out of root cuttings.
-
How did I miss those stunning Hepaticas. I want a yellow one
and a timely reminder to repot mine - can someone remind me of a good potting mix?
-
Has there been any new findings about this root cutting without part of the rhizome? Especially with H.nobilis?
Should be the right time now?
-
No luck with some I did last year.
-
Only just found this tread.
Don't I remember one nursery (Aswoods?) suggesting repotting each year into the same size pot by cutting off the bottom of the root ball, adding fresh compost and putting the shortened plant back? Seems we should use the bottom of the root ball too and hope, although maybe leaving the old root ball closer to the surface.
I guess it might depend on how much you paid for the original plant before you do this.
-
Many Japanese gardening books and magazines give Hepatica growing tips and some of them often mention propagation by root cuttings but few describe specific processes. It must be a fairly common practice. I found one article with some information. This article describes the process as follows:
Trim the thick part of the root to 1-2 cm from the top when repotting Hepatics as when roots get too long they become susceptible to rot.
Apply Benomyl paste or similar antibacterials to the wounds.
Pot the trimmed roots covering the entire part.
If you are lucky, you will see a new growth in the spring.
Last June when I repotted my Hepaticas, I trimmed those with long roots and potted the trimmings in separate pots. There were about 2 dozens of them. I just checked those pots and found 1 has a small bud forming. Not a very good yield but I am happy with it.
I will be more carefull how I pot the root cuttings this year.

-
This is all very informative, I think I will try this method also. :)
-
I just found this thread and I am catching up reading it! It's very interesting! Thanks Chris and Koko for the info! Actually I have read several Japanese web sites talking about this method but I didn't know we can use such small roots. I must try this method! ::)
These are the Japanese sites that show how to propagate from root cuttings but they are using bigger pieces...

In Japan, people do this method in the fall because if you do it in the spring, the roots might rot during the rainy season (June or July, when it gets hot and humid) and summer.
-
Pepa-san, thank you for posting links. They show the process clearly.
As you pointed out, most of my root cuttings did not survive because of the high temparature and humidity during the summer.
I will have to come up with ways to keep them drier without killing or take cuttings in the fall.
This year, I also want to try the method Chris showed.
Koko
-
Very interesting links, Peppa. They are using the older, lower part of the rhizome rather than individual roots. Maybe that is where I'm going wrong?
-
Absolutely fascinating thank you for posting Peppa.
Now I must summon the courage to try it!
-
What time of year do you think we should do it in this country Anne?
-
Just did it! Any time you are repotting and accidentally decapitate one...
-
Was looking for info about Hepaticas and saw this thread as well. You can start a single plant just from the stem with the leaf?

Very interesting to see if any replies come in, while I don't grow hepaticas had always thought that the best way to multiply was from seed.

The pictures on the NWNARGS page are my photos; while you could potentially root from the leaf, this method hasn’t been established as a reliable means of Hepatica propagation.
I first read about Hepatica propagation from leaf cuttings in the annual journal of the International Hepatica Society several years ago. The reason for the discussion was not to propose leaf cutting as a viable propagation method, but instead to evaluate its potential in emergencies: for example, if while repotting you accidentally broke a leaf off of a very expensive and rare plant that only had a few leaves to begin with. There was no real conclusion as to the method’s usefulness, and not a lot of people are willing to experiment too extensively as you have to use fresh leaves to do it. I have tried leaf cutting propagation on H. japonica, H. nobilis, and H. acutiloba, and the first two had some root growth on a few examples, but none of H. acutiloba had any growth. However, I just tried casually and I haven’t pursued it any further.
-
Thanks, Peppa, I thought you'd know!! :)
