Creeping woodsorrel has less upright growth and less showy flowers than Bermuda buttercup, a similar looking plant. The small flowers have five yellow petals. Two to five yellow flowers form a cluster that develops where leaf stalks and stem meet (leaf axil). Flowersįlowers are present almost year-round. Leave are gernally green but a variant with purplish leaves is also common. Leaves are alternate to one another along the stem and usually fold downward at midday and at night. In comparison to the leaves, leaf stalks are long, almost 3 inches (7 cm) in length. Hairless to sparsely hairy, leaves are fully subdivided (compound), each consisting of three heart-shaped leaflets that are 1/4 to 2/5 of an inch (0.6–1 cm) long and 1/6 to 1 inch (0.4–2.5 cm) wide. Leaves resemble those of clover and range from green to dark purple-tinged. Its creeping, aboveground horizontal stems grow to about 12 inches (30 cm) long and root at the stem joints (node) allowing it to invade new areas. The first leaf has three leaflets that are broadly heart shaped. Leaves are alternate to one another along the stem. They range from 1/12 to 1/5 of an inch (2–5 mm) long and 1/25 to 1/10 of an inch (1–2.5 mm) wide. The cotyledons (seed leaves) are oval to egg shaped and hairless, except for minute hairs along the edges that point upward. Yards, gardens, turf, landscaped areas, urban places, orchards, vineyards, fields, and agricultural crops, and nursery and greenhouse grounds and containers. Bermuda buttercup prefers shady conditions but can grow in sun.
Both species contain variable levels of oxalate compounds that when eaten in quantity, can cause death in livestock. It is related to, and closely resembles Bermuda buttercup (buttercup oxalis). It grows throughout California to 8200 feet (2500 m) and inhabits agricultural land, greenhouse and other disturbed sites.

BERMUDA BUTTERCUP NURSERY PROFESSIONAL
I recommended he call a local nursery or garden center and ask for the contact information of a professional landscaper or gardener for help digging out the weedy bulbs. Also, if they drift to garden plants, the herbicides listed in the publication can kill them. Unfortunately, herbicides will only kill the top portion of the plant, which will regrow. The caller had trouble bending over and digging and hoped he could use an herbicide to kill the weeds. However, you can hand pull or mow the top to deplete the bulb reserves but killing the plant this way could take years.
BERMUDA BUTTERCUP NURSERY MANUAL
The publication recommends manual removal of the whole plant, including the bulbs. I used the online IPM Pest Notes: Creeping Woodsorrel and Bermuda Buttercuptell him more about this weed. In his landscape, Bermuda buttercup had taken over a 50 square-foot area and was growing in and around other ornamental landscape plants.
