Dimorphanthera germination
« on: January 23, 2022, 03:08:48 PM »
Iíve received Dimorphanthera alpine seeds from the seed exchange for the last 2 years . I havenít had any germination . I havenít stratified them as I thought they were from a warmer climate like vireya rhododendrons .  As theyíre pretty small Iím assuming they need light .
Has anyone had any success with these ?

E Meaney,

Dimorphanthera, like most members of Epacridaceae, needs about 2 years of alternating 90 day cycles of 20C and 4C [starting with a warm cycle] and must NEVER dry out.  You would do well to sow in a mix of  finely ground sphagnum peat and vermiculite, in several layers of ziplock bags, so it can be transfered between 20C and 4C without drying out..

I am in USDA zone 8b where temperatures almost never fall below 15F  -9.4C.  Rainfall 50"+  but none  June-+September.  We seldom get snow; but when it comes we get 30" overnight.  soil is sandy loam with a lot of humus.  Oregon- where Dallas is NNW of Phoenix.

Very interesting and not easy to do . However that probably means my seeds are still alive . I suppose the last batch will have had around 90 days in the warm and the other one is on a high shelf in my greenhouse so I better stick them in the fridge .
Worth a try .
Thanks for the information.
