Gardeners' Notes:

Years ago I was given this Shamrock plant and planted it right in the ground under a tree. It does very well in cooler months and even survives cold snaps as low as 30. Grows best in shaded area with filtered morning sunlight. I've moved it twice when shade trees were cut down, since it didn't do well in direct FL sunlight...transplanted very well. I've had one plant in a clay pot for well over five years and it displays most beautifully From Jan. through April.

Oxalis triangularis 'Charmed Jade'(R), 'Charmed Wine'(R), and 'Charmed Velvet'(R) are bred by a Hungarian breeder Jzsef Retkes. I was so lucky and I had chance to see his collection. PW will introduce his new varieties in the folowing years. These varieties in Europe are running under the name Oxalis triangularis Xsalis (TM) 'Frosted Jade' (R), 'Burgundy Wine' (R) and 'Black Velvet' (R).
(Propagation is prohibited...)

I have compared them with other Oxalis triangularis varieties. The Xsalis varieties are emerging faster, they have got bigger leaves and flowers, and they are unique in leaf coloring.

New varieties will be introduced sooner! So keep looking for new shamrocks in your local nursery.

This plant can survive to Z7 I think, it is not hardy where I live.
