I remember the Castor Bean challenge thread from last year - but mine were so pathetic that I could never have posted any photos!
I am growing both the green & red this year in my veggie garden, to (hopefully) deter the rodents from munching on my Asparagus roots. In the rich composted garden, they are the tallest ones I have ever grown!
My question is this: Will the two colors cross, & produce a somewhere-in-between color seeds?
A couple already have seeds - I am hoping that they will stay true, if I keep the seeds spearated by plant color. Anyone know if this will work?
Thanks -
