Impatiens "Blue Diamond" germination help needed

Elsa123 Pretoria, South Africa Aug 07, 2007

I've tried before to get these to germinate, without any success. I was lucky enough to get some more to play with and would really appreciate any tips.
I sowed the previous seeds on the surface of some peat seed starter compost . Kept it moist, enough light (no direct sunlight) not too warm as I read high temperatures inhibit germination, but not even one germinated...

Thanks in advance,
Elsa

Hi,Elsa,
Last year I sowed this seed in the glass case outside in February.
And, good germination could be obtained. This year I sowed them at the same time again, but none to germinate. Fortunately, I got some selfseedlings and I could glow them. Because of my poor experience, I can't exactly tell the right sowing time ,but I think that this Impatience needs some cold period for germination the same as other Impatience species ,
Late autume sowing or winter sowing might be better for this seed.

Good Luck !!
