I've got some seeds that I harvested from two of my rhubarb crowns this year, I moved them to a different plot so didn't harvest them to let them settle in and strenghten up.
The're both timpany early's that I grew from seed but are planted in with two victoria that I also grew from seed and two unknown crowns that i had on my plot. I sowed my TE in Feb indoors. i've got well over a 100 so if you want any PM me for my address and send a SAE
on re-reading some other post it seems the done thing is to pm your address if you want some seeds so just do that instead of asking for my details :D
