South African oxalis are well suited to California's summer dry climate. This species grows from densely clustered bulbs, with erect 6-12 inch stems and brushes of narrowly parted bluish green leaves, appearing in early fall and lasting until spring. One-inch blossoms painted bright rose pink are clustered at the stem ends in fall and winter, creating a vivid display. This oxalis does not creep or seed about like its less well mannered relatives. Sun to light shade, moderate watering during its growing season, hardy to 15-20 degrees F. Can go dry in summer.
