Appearance
Boechera plants are typically herbaceous, with a basal rosette of leaves and elongated flowering stems. The leaves are generally hairy and may be either simple or compound. The flowers are small and have four petals that are white, pink, purple, or yellow. The fruit is a long, narrow seedpod that splits open when mature, releasing numerous small seeds.
Care Guide
Boechera plants are generally easy to care for, requiring moderate watering and fertilization. They prefer well-drained soil and full sun to partial shade. Boechera plants are generally hardy in USDA zones 3 to 8.
Watering:
Water Boechera plants regularly, ensuring that the soil remains moist but not waterlogged. Avoid overwatering, as this can lead to root rot.
Fertilization:
Fertilize Boechera plants with a balanced fertilizer once per month during the growing season. Avoid overfertilization, as this can cause excessive vegetative growth at the expense of flowering.
Soil:
Boechera plants prefer well-drained, slightly acidic soil. If your soil is heavy clay or alkaline, amend it with organic matter such as compost or peat moss.
Sunlight:
Boechera plants prefer full sun to partial shade. If you live in a hot climate, provide afternoon shade to protect the plants from excessive heat.
Hardiness Zones:
Boechera plants are generally hardy in USDA zones 3 to 8.
Common Pests & Diseases
Boechera plants are relatively pest and disease-free, but they may occasionally be affected by aphids, whiteflies, or powdery mildew. To control pests, use insecticidal soap or a neem oil spray. To prevent powdery mildew, ensure good air circulation around the plants and avoid overhead watering.
Habitat
Boechera plants are found in a wide range of habitats, including alpine and subalpine meadows, open woodlands, and rocky slopes. They are generally adapted to cool, moist environments, but some species are found in dry, desert habitats.
