ON THIS PLANT

Orthocarpus cuspidatus is a species of flowering plant in the broomrape family known by the common names Copeland's owl's clover, Siskiyou Mountains orthocarpus, and toothed owl's-clover. It is native to mountain and plateau habitat in Oregon, California, and Nevada. It is an annual herb producing a slender, glandular, hairy, purple-green stem up to about 40 centimeters tall. The narrow leaves are up to 5 centimeters long, the upper ones deeply divided into three linear lobes. The inflorescence is a dense cylindrical spike of wide, oval green bracts with pinkish points. The flowers emerge from between the bracts. Each purple-pink flower is fuzzy in texture and club-shaped, the lower lip an expanded pouch and the upper lip a narrow, straight beak.

CARE GUIDE

How to keep Orthocarpus Cuspidatus.

Light

Copeland's owl's clover comes from sunny, open habitats and does best in full sun. It will tolerate partial sun but favors direct sunlight for optimal growth. This plant, which can be annual or biennial, is known for its sun-loving nature.

Water

Copeland's owl's clover thrives in areas with consistent rainfall and requires a balanced watering schedule, with watering once a week for optimal growth. It prefers herbaceous outdoor settings and flourishes in temperate climates, benefiting significantly from rainwater. This makes it an excellent choice for gardens.

Temperature

Copeland's owl's clover can handle a wide range of temperatures, but its distribution may still be restricted by various combinations of moisture and heat. It does best in warm summer climates with sufficient rainfall or watering. Long periods of cloudy, rainy weather or prolonged high temperatures can increase the chance that Copeland's owl's clover will die. In winter, protecting it from the cold can improve its survival rate.

Fertilizer

When most of Copeland's owl's clover's blooms have fully opened, it's time to start fertilizing again. At the peak of blooming, resume fertilizing every three to four weeks, weather permitting. When the plant begins producing fewer new blooms, stop fertilizing; there's no point in fertilizing once it can no longer produce additional blooms.

Pruning

Copeland's owl's clover is known for its vibrant flowers and distinctive shape. To encourage growth and flowering, prune the plant in early to late spring, removing any dead stems. Ensure good air circulation to help prevent disease, which will promote vigorous blooming in subsequent seasons. This will keep your Copeland's owl's clover thriving and attractive year after year.
