Plantidote of the Day 2010-12-27
Buttercup oxalis or Bermuda oxalis
A native of South Africa, buttercup oxalis was originally brought to America as a decorative landscape plant. It's such a sweet little thing, with its shamrock-like leaves and bright yellow blossoms nodding gracefully on slender stems. Plus, it's low maintenance and it blooms in the winter; the one shown here is in bloom right now! Cheerful, resilient, attractive -- clearly a plant with no downside, right?
Wrong, according to California Invasive Plant Council, which says buttercup oxalis is turning up in places where it does not belong, like agricultural fields. These plants will also pop up on lawns and gardens, whether you want them to or not. Getting rid of oxalis is like removing mint from a garden -- next to impossible. The one pictured here is growing in a pot, which prevents the rhizomes and bulbs from fulfilling their mission of global domination. So far, so good...
