Tickseed
Coreopsis leavenworthii

This is our state wildflower which is abundant along moist roadsides in the spring and early summer.  Just get a few started along the edge of your swale and spread the seeds as they ripen for an even better turnout the next spring.

Too bad this isn’t around all year although you can start new ones from seed at any time in trays and plant them in your garden for an off season splash of color.

Mix with Prairie Iris, Yellow Canna, Duck Potato, or just plant above the water  line of a lake where the soil stays moist yet won’t flood and kill them.
