Lucky clovers are emblematic of St. Patrick’s Day lore and celebrations. Although Oxalis resembles their Irish cousins with their 3 leaflets per stem, they can be invasive when left to roam freely in the garden.Along the west coast, a South African native oxalis commonly known as Bermuda Buttercup appears in open fields, along freeways and in gardens from late winter to spring. They stand 12-inches tall bearing bright yellow clusters of flowers and spreading by bulbs and seeds. The seed capsules are capable of propelling seeds as far as 6-feet! The Bermuda Buttercup may be colorful and pretty, but once established, it is very difficult to control and can smother other less vigorous plants.
To Keep Oxalis Under Control
:
-
Dig them out of planting beds, lawns, slopes, etc. before they have a chance to set seed
-
Use a pre-emergent herbicide that is listed for use on lawns and bedding plant areas
-
If you don’t have time to start digging them out while they are in bloom, cut off the flowers before they have a chance to disperse their seed capsules
