Plants have narrow, gray-green leaves on upright, branching stems. Reaches 1–2 feet tall. Blooms from late spring to early fall.

Grows well even in heavy clay garden soil

Most cornflowers struggle with compact clay dirt. This one only needs a little compost to grow strong roots and bloom fully.

Holds up great in hot summer weather

We hit 93°F for two weeks in July. Pale flowers wilted flat, but these stayed upright and bloomed daily.

Rare dark purple bloom hard to find locally

I checked multiple local garden shops and none sold dark burgundy cornflowers. This seed grows such moody, eye-catching blooms.

Perfect for homemade dried floral wreaths

I hang the blooms upside down to dry. They keep their rich purple hue all winter for front door decor.

Pair with yellow blooms for more butterflies

I mixed these dark blooms with golden coreopsis in my wild meadow. The color contrast brings loads of butterflies.
