I'm learning from my friend Anita some of the things I can and can't grow here in the AZ desert. Our soil tends to be pretty rocky and sandy - so I do my gardening in Earth Boxes and clay pots. I've never attempted to start with seeds - seedlings do me fine - thank you very much!
However, after reading what my Canadian friend Stephanie writes about - I've got my interest perked up. She's done quite the research of seed companies. You Go Stephanie! Roses to you! Oh, may seeds of roses to you :-)!
