The story

Blazing star does something odd: its flower spike opens from the top down, the opposite of nearly every other spike in the garden. It grows from a corm, like a crocus, in wet prairies and meadows.

Planting

Full sun and average to moist soil. Plant the corms in fall or spring, 2 inches deep.

Growing

Stake in rich soil or grow it among grasses that hold it up. Leave the seed heads for goldfinches.

Harvest and use

A top butterfly flower in July and August, especially for monarchs and swallowtails. It is a long-lasting cut flower too.

What to watch for

Voles eat the corms. Wet winter soil rots them.
