Astrantia & Stratification

02 March 2010 00:24:37

Last autumn I sowed several trays of seeds and left them in the greenhouse to overwinter.

They were all seeds that required, or would tolerate, stratification - Sarracenia, Astrantia, Verbascum, Aquilegia.

I note the definition of botanical stratification - simulating winter conditions to promote germination by chilling to ideally +1° to +3°C -  not freezing.

Given the abominable winter we have had, with temperatures of -10, I had given up on my seeds in the greenhouse for lost. However, yesterday I decided to take a little look at them. 

No sign of life in most trays but the Astratia tray did have one seedling peeping up. I decided it was probably a weed and left it. But today I went back to check again and have found several similar seedlings peeping up in the same tray.

So, for anyone who may have inadvertently collected a few Astrantia seeds in Belvedere at the Garden.ie get-together last year, GO check your seeds!

Just reminds me to do somethng with my astrantia. And meconopsis for that matter. Is it better to leave it in the fridge or outside do you think?

You must have missed that Gardeners' World episode, Jacinta : )

Krista, the fridge is surely best as you don't know what temperatures you will get outside.

As I said before so glad I now did'nt throw out my astrantia seeds they were in the chucking pile and all, have brought them back into the greenhouse and will keep a hopeful eye on them, thanks Rachel.
