Do Camassia come back every year?
Camassia are perennials, growing from small, pointed bulbs. Plant between September and November in moist, well-drained soil as they like damp conditions to thrive. They will even grow in heavy soil although it is important to ensure that the soil drains well as bulbs will rot if they are waterlogged. Camassia like moist (but not waterlogged) soil in full sun or light shade. Left undisturbed, they will increase in numbers over the years. In very cold gardens, apply a thick mulch in autumn to provide protection from winter frost.If camassia bulbs are left undisturbed they will gradually multiply making them perfect for naturalising in grass or transforming a rough lawn.

They look marvellous planted in swathes with grasses and meadow flowers for a natural, easy style of garden.You should space your Camassia bulbs about 10cm apart in order to give each individual flower plenty of room to thrive. These easy-to-grow plants are perfect for borders and grow fantastically in moist soils near ponds.
How hardy is Camassia?
Blooming Season: Camassia typically blooms in late spring to early summer, filling a gap between the spring bulbs and summer perennials. Hardiness: Camassia is a hardy plant, tolerating winter temperatures in USDA hardiness zones 3 through 8. Crocosmia performs best when planted in full sun. In hotter climates, some afternoon shade will allow the blooms to last longer. Locate in an area that is also protected from hot, dry wind.Cut down spent flower stalks, but don’t remove crocosmia foliage until it dies back naturally at the end of the growing season and when it turns light brown.Crocosmia Maintenance Keep the soil moist by watering your crocosmias once a week during the growing season. Deadhead crocosmias regularly to encourage new blooms. Cut the stem back where they meet the leaves.Crocosmia corms are similar to bulbs and the best time to plant is early spring, so they hydrate in the early spring rain. Once hydrated, Crocosmia will grow as soon as the soil warms up in early spring.
What do you do with Camassia after flowering?
Plant camassia bulbs in autumn, in humus-rich, moisture-retentive soil in full sun or part shade. They’re happy in heavy clay soil and will grow in acid, neutral or alkaline soil. Allow the foliage to die back naturally after flowering and divide congested clumps in summer. Camassia like moist (but not waterlogged) soil in full sun or light shade.
