Dropseed Rockcress

Boechera pendulocarpa

Also Known As - Holboell's Rockcress
Dropseed Rockcress (Boechera pendulocarpa) is an evergreen sub-shrub found in rocky alpine slopes of western North America. Growing up to 8 inches tall, it displays beautiful green foliage and small, white, bell-shaped flowers that mature to a deep purple color. The flowers are followed by pendant, rounded fruits that resemble pea pods, which give the plant its name. Once established, Dropseed Rockcress is a low maintenance plant, preferring well-drained sandy soil and light shade for optimal growth. As a tough and drought-resistant species, it's ideal for sunny and dry locations in rock gardens, containers, and native plant gardens.

watering

Dropseed Rockcress prefers consistently moist soil, so the best way to take care of it is to water it when the top 2-3 inches of soil is beginning to dry out. This generally occurs about once a week during the summer months, but will depend on the amount of sunlight the plant is receiving, the temperature, and humidity. You should water until the soil is thoroughly saturated, then allow it to drain. In the winter months, when the plant is dormant, you should cut back on watering and only supply enough to keep the soil from drying out completely.

sunlight

Dropseed Rockcress plants generally prefer full sun exposure, meaning at least 6 hours of direct sunlight each day. However, these plants can thrive in partial shade, too. It is important to note, however, that too little direct sunlight may cause the plants to experience a reduction in flower production and an overall decrease in health. In general, it is best to provide the plants with at least 4 to 6 hours of sunlight each day for optimal growth and health.

pruning

Dropseed Rockcress should be pruned quarterly to ensure the health and longevity of the plant. Pruning should be done in late winter or early spring, right before the emergence of new growth. During pruning, remove any flower spikes that may have developed, as well as any dead or damaged leaves. Trim any spindly shoots to encourage bushier growth, and thin out crowded areas to promote air circulation. Finally, remove any yellowing leaves to reduce the risk of disease.
