Oxalis Triangularis bulbs - Purple Shamrocks for Indoors or Out! Most gardeners choose plants based on their flowers, but leaves are a big part of what we see year round. Triangularis leaves are a stellar purple, with deep rose patterning and a zippy geometric shape. For small plants with huge impact, mix triangular with silver leafed partners like Japanese ferns or artemesia or chartreuse mates as our photo shows. Exceptionally handsome in light colored ceramic pots. Also excellent as houseplants on a sunny windowsill for rich color all winter.

1
Spade or till the soil to a depth of 8 to 10 inches. Dig in 2 to 3 inches of compost or manure, as crocosmia prefers rich, well-drained soil.
2
Plant crocosmia when the soil is at least 55 degrees Fahrenheit and all danger of frost has passed. In cooler soil, the corms are susceptible to rot.
3
Dig a hole for each corm, making them deep enough that the corm will be at a depth of 3 to 5 inches. Allow 6 to 8 inches between each corm.
4
Water crocosmia deeply after planting. Thereafter, water regularly throughout the growing season. Provide enough moisture to saturate the roots, and then withhold water until the top of the soil feels dry. Never over-water, as crocosmia is relatively drought-tolerant and the corms may rot in soggy soil.
5
Watch for spider mites, which often feast on the foliage of ornamental plants. Spider mites look like tiny specks that gather en masse on the underside of leaves. Insecticidal soap spray is often an effective method of control. Healthy plants are less susceptible to damage.
6
Protect crocosmia from slugs, which often chew holes in the leaves. Prevent the pests by removing leaves, grass clippings and other plant debris from the soil around the plants. Control infestations with slug bait. Apply the bait strictly according to label guidelines.
