Seedy Subjects! > Grow From Seed

Kelseya uniflora

(1/2) > >>

Fumi:
Can someone advise me on how to grow this species from seeds?  I'd gotten a packet of seeds last year which, to my surprise, germinated quite readily in my basement before I had a chance to expose them to some cold.  We were still looking at another 2 months of sub-zero temp so I kept them inside (15C min/22C max) but they all eventually died out before Spring arrived.

Seeds were sown in a 50-50 mixture (roughly) of grits and peat humu.  I watered the pot almost every other other day but sometimes with a break of 2 or 3 days in between.  None got far enough to transplant them unless they needed to be transplanted into a different mixture early.

Any way, this pot of seeds was kept and I'd put them out this time to see if there are anything left from last year.  I also got another packet of seeds for this species.  This time, if I'm lucky and have more germination, I'd like to at least see them survive the first few months and hopefully longer!

I already breed plants for 40 years.  I place the pots outside in good light, with the pots open to the weather, including frost, and I do not allow them to dry out.
I sow Kelseya uniflora the first time 1992. From 1992 to 1998 I did sow each year seed however it germinated not. 1999 germinated the seed which I sowed 1998. These plants grow currently in a large tuff and have a diameter of  2 - 3cm.

Hi Franz,
Thank you for sharing your experience.  It seems that I was lucky last year getting good germination rate.  I hope I'd be as successful this year.

I'd heard that this was slow growing species but didn't realize that it was that slow.  Are you still maintaining some moisture but was that only in the earlier stage (i.e., seedling)?

Hi Fumi
I have had the same sort of experience with growing Kelseya uniflora as Franz. If the seeds arrive before the conditions ar right I store in plastic sandwich boxes with a sachet of drying agent (the sort you get with camera equipment) then put them in the fridge. This will enable you to sow some as before to get warm germination which you can harden off at the right season. Always a good idea to try different methods if you have sufficient seeds. I have sowed it in December and left out in the cold & wet and got only 1 or 2 from a batch but these survived well. But waiting for the flowers is a long job. Mine was about 10 years or more to reach about 10 cm before it flowered and then just a sprinkling. It needs pretty free draining compost to keep it tight and in character. Sadly mine got a rot at about 16-17cm and went to the great compost heap in the sky but it did have a last flourish of flowering. I just have a single 4cm specimen left and a long wait!!
Good luck with yours
John F

Hi Fumi,
I grow Kelseya uniflora outside like many other plants. Therefore is watering not necessary in winter. All seedlings are not to dry up.
