Today I knocked my small collection of Roscoea out of the large pot they all share. I bought them in 2013 and I'm amazed at how prolific some are or not
-
and some more
Now to divide them and give them their own homes in 2L long toms until they get a new home. I guess its easiest to split them every year
-
They look like some peony roots. ;)
-
Which ones are you growing Mark. The roots all look very healthy. I found they like my garden so I have bought two new ones this year to add to what I have already. I decided to grow some from srgc seed ex. I had an excellent result but I might have been a bit too hopeful because I potted on the seedlings. I sunk them in their individual pots into a larger pot. I hoped I had given them plenty of drainage. I did mean to cover them over with a sheet of glass to keep the rain off them but got caught up in family stuff.

From whom did you buy your Roscoeas in 2013?
They all look very healthy.
Thanks

Some have produced only one extra tuber while some have become 4

cautleyoides, cautleyoides early form, cautleyoides Jeffrey Thomas, Red Gurkha, Evening Star, Harvington Royal, Raw Silk
I see no difference between Evening Star and Harvington Royal. I asked Twelve Nuns about it but they didn't answer
-
Mark
What mix did you use?
-
For the last two years they have been in a recycled bulb mix of grit, sand and top soil. Today they were planted also in recycled pot contents but more top soil was added
-
Mark, nice growth on those plants! I'm trying to build a small collection here- a real challenge since they are virtually unheard of in Nova Scotia. Does your Red Gurkha ever set seed? I've been growing several others from from SRGC seed exchange seed, but have never seen seed of Red Gurkha on offer. A few of my seedlings will be large enough to transfer to the garden this summer (if it ever arrives).
-

I don't remember sorry.
I did collect a load of seed from cautleyoides early form
-
Having a reputation for killing plants indoors I bought outdoor hardy roots from Hartside Nursery near Penrith at an SRGC show. This is R. Cautleyoides. They produced big flower heads on sturdy stalks and it was interesting to see how the seeds were produced. I also bought Harvingtons Raw Silk.
-
You need to be very quick to collect seeds. One day its a pod and the next it has burst spreading the seeds
-
In February 2014 again from Hartside at an SRGC show I bought Evening Star and Harvington Royale. Both are purple and quite alike but there are differences. I have to say your two look identical. This year I got Lemon Guardian and McBeaths Pink. The former was sourced by the nursery from a breeder but he did say I was unlikely to find out much about it on the internet. I look forward to seeing what it produces. McBeath's Pink was highly regarded in recent trials. I will keep in mind what you have said about the seeds going fast. Would it help to put a bag over the head, to catch the seeds, as is done with hepaticas.

A note about roscoea seeds. They disperse On a rainy day. If you are afraid you will miss them you can collect unshed seeds and hang in a net bag in the rain and they will then fall out. If you let the pods dry it is then a nightmare to open them. Susan

Thanks Mark

Thank you for that tip Susan.

Two photos of Roscoea McBeath's Pink taken this evening 7.6.15. The edge of the sheath leaf is noticeably red on the original photo but is not showing too well on the resized photo.
-
McBeath's Pink is lovely, Sheila - I've not seen that one.
-
Caught this one with 7 blooms open last night
Roscoea humeana 'Alba'
-
Crikey, that is lovely. R. humeana Alba is my favourite Roscoea and that photo shows why!
-
Roma the white one is stunning. I have not seen a white one before. Maggie McBeath's Pink shown on the label was pale pink so I was a bit surprised to find it was not really pink. I read the RHS Trial records where it was given an AGM and it describes what I have. I am very pleased with it.
-
Roscoea humeana Alba was on my wanted list since I first saw a photograph of it but I never saw it for sale. In my first attempt from seed one flowered pink and then all were lost in the 2010/11 winter. I tried again and have two flowering, both white. I saw it on Hartside's stall at the Early Bulb Display in Dunblane last year and could not resist buying. The seed grown plants are smaller with smaller flowers but hopefully they will improve with age.
Harvington Evening Star has just poked through the ground outside so I can replant Corydalis cashmeriana now I know exactly where the Roscoea is.
-
I dug up and saved some nice pure white flowered seedling from Roscoea Kew Beauty last year.
This is how they flowered this year, rather disappointing.
-
This little Roscoea was in a batch of un named seedlings I got from a group meeting.I'm guessing R.scillifolia
