Re: oxalis

Nan asked:

"I'm looking for a recommendation for low-growing, "tough" oxalis to plant
between pavers.  Full sun, water moderate, yellow or white flowers, not
more than 4 - 6" tall (except flowers)."

There are over 200 species of Oxalis to pick from. Some are gorgeous, some
are menaces, some are both. You need to be careful.

I'd recommend O. obtusa. Not tall, less than 4 inches it comes in yellow,
pink or white forms. It bears masses of flowers from Novemberer until, well
even now. There are many other species that you should contact the
International Bulb Society about. O. luteola is another good one with large
(over an inch across) yellow flowers and heavy leaves that are dark red
underneath.

Avoid our favorite foe O. pes caprae and also O. corniculata. I see that
Sean did recommend the second one - well it is a weed dreaded by nurserymen
in many parts of the world although not so aggressive as O. pes caprae.
Anyhow, you can avoid the risk and find far more brilliant colors and
larger flowers in the Oxalis clan. They are great for rockeries.
