Dear Friends, Many thanks for all the recommendations. I will have to study these more. I've checked out some pix on the wiki. Both Oxalis gracilis and Oxalis inaequalis sound kinda like 'my kind of flower' although O purpurea sounds easy and with a wide range of variety. Guess I'll have to keep my eyes open for BX offerings. O. versicolor is just covered in blooms now. My only deliberate species. Thanks for all the input. Best Jim W. -- Dr. James W.
