What They Are
Appearing just after the snowdrops, the reticulata irises are among the most beautiful of early-spring bulbs. They derive their name from the species Iris reticulata, although many named varieties are hybrids with other species, chiefly I. histrioides and I. bakeriana. All are native to mountainous areas of eastern Turkey, Iran, and the Caucasus. Most varieties grow from four to six inches tall and bloom in jewel-like tones of blue and violet (the closely related I. danfordiae and I. winogradowii add yellow to the palette). On warm days, the flowers are delightfully fragrant.

How to Grow Them
Reticulatas will grow in almost any soil, provided it’s well drained, but do especially well in sandy loam. In their native haunts, they receive plenty of moisture from melted snow in early spring; by late spring, when the leaves begin to turn brown, the soil begins to dry out, although complete dryness, especially in late summer, will result in poor flowering the following year. Reticulatas are not greedy feeders, but do appreciate a light application of low-nitrogen fertilizer at the beginning of the flowering period. Full sun is best, although a half-day of sun is adequate. Many gardeners complain that reticulatas tend to dwindle and disappear fairly quickly in the garden. The best way to counteract this tendency is to space the bulbs generously and to replant them in late summer (in fresh soil, if possible) every two years. Bulbs should be planted two inches deep.

On the Web
Alan McMurtrie, a Canadian engineer, has been pursuing an energetic hybridization program with reticulatas in recent years. He has produced a wide range of fascinating seedlings, many with atypical flower colors, including white, pale through bright yellow, brown, violet pink, sea green, and blue-yellow blends. Photographs of these intriguing plants (some of which are scheduled to be released commercially) can be seen on his Web site, http://reticulatas.com.
