Gardeners' Notes:

A beautiful plant, with very blue foliage and big pink flowers. This would be worth growing for the foliage alone.

I'll confess that my plants lasted only a year, but the next time I plant this I'll give it the sharp drainage it needs to survive our wet New England winters (Z6a).

Bulbs are cheap from the online vendors of fall bulbs.

this is fascinating silvery foliage which is why it's also called Silver Shamrock. It's like your own little secret because it's soooo small,
making it all the more alluring. i purchased mine in the fall from easy to grow bulbs and was very pleased.

Chilean Wood Sorrel is native to the high mountains of Chile and Argentina. The leaves are gray-green, tipping downward. The clustered flowers are lavender-pink, darkly veined, with a red eye, and bloom from mid-spring to early summer.

Chilean wood sorrel reproduces by cloning tubers as well as seed, and dividing the tubers is the best method of propagation. The tubers are roundish and form a hairy wad.

The compact, ground hugging habit, silvery foliage, and attractive blooms make O. adenophylla a wonderful rock garden, ground cover, or border plant. It is, however susceptible to excess winter moisture, and winter mulch is recommended. O. adenophylla can also be grown as a house plant.
