Snow and freezing temperatures arrived early in Iowa this year, but I’m not ready to put Bleeding Heartland’s wildflower series to bed for the winter yet.
The bitter cold inspired me to pull out some summertime pictures for this week’s edition. I took all of the photographs enclosed below in the parking lot of the Greater Des Moines Botanical Garden in late August. Some wonderful prairie plantings are in front of the main building and along the nearby bike trail.
Tall coreopsis (Coreopsis tripteris), sometimes known as tall tickseed, is native to most of the U.S. and Canada east of the Rocky Mountains. UPDATE: Bleeding Heartland user PrairieFan notes in the comments that “tall coreopsis is native to the southern half of Iowa, but not the northern half.”
It can grow in many types of habitats, from disturbed ground to high-quality prairies. The Missouri Botanical Garden’s website advises that tall coreopsis is easy to grow “in dry to medium moisture, well-drained soil in full sun,” and “Thrives in poor, sandy or rocky soils with good drainage.”
According to Aaron Harpold, assistant director of horticulture for the botanical garden, the plants I photographed were a cultivar, not grown from seed collected in the wild. For any interested gardeners, the specific type is Coreopsis tripteris ‘Flower Tower.’
