Crocus vernus ‘Joan of Arc’ (Dutch Crocus) is a large cupped Crocus that greets spring with snow-white petals and bright orange pistils. An early spring bloomer, it will naturalize well over time creating drifts of white in the garden. With grass-like leaves they can also be planted in a lawn providing a welcome display. Give them six weeks, post-bloom, before mowing so the bulbs can regenerate and they will reward you by increasing in the coming years. To establish an area, plant them by the dozens in well-drained garden soil, avoiding heavy clay, in a full sun to part shade location. The flowers will bloom for about three weeks, closing at night and opening with the sun and each corm (bulb) will produce several flowers. Squirrels seem to have a pesky knack of finding newly planted corms, so if they are a problem, simply cover the planted area with a piece of chicken wire. As Crocus multiply, they can be gently dug up in the autumn and replanted every 4-5 years. 4-6" tall x 4-6" wide.
