What a great opportunity PBS provides for introduction to new bulbs. I am one of those who have avoided oxalis due to its weedy reputation. I do not have a collection and most things go into the garden so I did not want to take the chance. I think I will be experimenting more in future. Kathy S., gardening in what is supposedly Sunset zone 7, but the town is in the Sierra Nevada foothills, California, USA and rises over 1000 feet. My own observations suggest my microclimate is zone 8 or even 9, Mediterranean climate with our rainy season just starting. vikingdoc@earthlink.net
