Oxalis (S, F)
O.deppei and O.regnellii are hardy to Zone 8 with protection.
O.adenophylla and O.triangularis are hardy to Zone 6 with protection.
Prefers a sunny or partly shaded, sheltered place in the garden. Plant bulbs 2" deep and 4"-6" apart. In colder zones, oxalis makes a most rewarding houseplant. Set 1 bulb per 4" pot or 3 in a 6" pot in well-drained potting mix. Cover with 1" of soil. Keep moist and feed monthly with a houseplant fertilizer until plants go dormant.
