I have some seed I can't find sowing instructions on because the traditional way to propagate it is through cuttings. But I have seed and I wondered if anybody nows how to sow it. I looked on Tom Clothiers site, and also JLHudson, but nothing was listed for this plant.

There you go Suzy :) From "From Seed To Bloom" by Eileen Powell, I needed to look this one up too glad I did didn't know they needed prechilled!
I've never grown them before but it says to chill the seeds for 10-12 wks. and I have so many other seeds to sow I'm just keeping the packet in the fridge until I get ready to sow it. The pot in the fridge sounds good but no room in my fridge or you could use the baggie method, I'm trying that a little more this year. :)
