Bulbs and bulblike plants, Perennials, Flowers
Most of these grassy perennials are native to moist meadows, marshes, and fields in Northern California and Pacific Northwest. Rosettes of grasslike leaves send up slender spikes of loosely spaced, starlike blossoms in spring.
Plant in fall after weather cools, setting bulbs 3–4 in. deep, 6 in. apart in good, moisture-retentive soil. Locate bulbs where they can remain undisturbed for many years. Because plants die down completely after bloom, set them where other plants will hide their yellowing leaves and fill in when leaves are gone. Bulbs can get by with less water during summer dormancy.
