Spring-blooming Crocus

Spring-blooming Crocus

You know spring has begun when crocuses begin to grow, even through the snow. Their cheerful hues of white, yellow, and lavender are most welcome after a winter of muted browns and grays. First to appear are the narrow, strap-like leaves. Then the cup-shaped flowers emerge, opening into bright 6-petaled stars.

Growing crocuses is easy, but you have to plan ahead. Purchase their bulb-like corms in September for best selection. Planting in early fall gives the roots time to grow before the ground freezes. Set them 3 – 4 inches deep in amended soil, where they can remain for years. After bloom, remove the faded flowers and feed the plants with an all-purpose fertilizer. Let the foliage dry naturally as the corms go dormant.

Landscape Use
Crocuses are effective used as edging or massed for a natural effect. For something different, scatter them into a lawn, where they will bloom before the grass starts to grow.
