Oxalis planting and growing

Oxalis. - A number of hardy species of oxalis are excellent plants for rock-work and edging. The greenhouse species are very showy, growing without extra care, and blooming freely through the late winter and spring months and some of them make excellent window-gardening subjects.

The house species are mostly increased by bulbs, a few by division of the root. O. violacea is, one of the commonest of house-plants. Give a sunny window, for the flowers open only in sun or very bright light. The bulbous (tuberous) kinds are treated much as recommended for Bulbs, except that the bulbs must not freeze.

The tubers are started in August or September for winter bloom. It is best to use deep pots, or the tubers will throw themselves out. The crown should be near the surface. After flowering, the bulbs are dried off and kept until new bloom is wanted.
