Summary

Dipterostemon capitatus, commonly known as Blue Dicks, is an herbaceous perennial that originates from corms. It is native to grasslands, open woodlands, and chaparral regions of western North America, particularly California. The plant typically grows to a height of up to 60 cm and features a slender stem with a loose inflorescence of 2 to 15 flowers. The flowers exhibit a range of colors, including blue, blue-purple, pink-purple, or white, and are quite showy when in bloom. Flowering occurs primarily in March and April, with the peak of blooming in March. Blue Dicks is adapted to a Mediterranean climate with wet winters and dry summers.

In the garden, Blue Dicks is valued for its drought tolerance and attractive springtime flowers, making it a suitable choice for wildflower meadows, native plant gardens, and xeriscaping. It is also a beneficial plant for pollinators. While seeds can be sown in the fall and typically germinate without special treatment, they take several years to reach flowering size. Propagation by corms is recommended for quicker establishment. Blue Dicks prefers full sun to part shade and requires low amounts of water once established, thriving in soils with medium drainage. It has no major disease problems, but overwatering can cause rot.CC BY-SA 4.0
