Oxalis debilis

pink woodsorrel

Nonnative to Florida

Species Overview

Introduced to the United States as an ornamental plant, Pink woodsorrel (Oxalis debilis) was documented in Florida as early as 1930. While considered invasive in parts of the Pacific and Asia and noted to be spreading quickly in the US, it has not been designated as invasive in Florida. There are eight species of Oxalis documented in Florida although only two are native.

Species Characteristics

Family: Oxalidaceae

Habit: Perennial herb, 6-12 inches in height.

Leaves: Compound with 3 heart-shaped leaves per stem.

Flowers: 2-12 flowers are clustered in an umbellate cyme. Individual flowers are pink to lavender with 5 veined petals and yellow stamen.

Reproduction: Small ovoid bulbs and rhizomes.

Distribution in Florida: Statewide


Some consider it to be problematic in home landscapes and food gardens as it can form dense colonies via rhizomes. It is also very adaptable to many growing conditions and habitats.

Control Methods

Preventive Measures

Check any incoming plant material for stowaways.


Hand pull ensuring all bulbs and rhizomes are removed.


Mowing is ineffective and rototilling can actually stimulate growth and spread rhizomes.


None known.
