Colebrookea oppositifolia: complete guide

Overview

Colebrookea oppositifolia, better known as Indian Squirrel Tail or Opposite-leaf Drysophylia, is a unique, herbaceous plant from the Himalayan region. The plant grows primarily in Pakistan, India, and China. The common name 'squirrel tail' refers to the unique shape of the inflorescence. This is a beautiful plant for alpine plant enthusiasts and for greenhouses.

Appearance and bloom

Colebrookea oppositifolia grows into a compact shrub reaching 30 to 60 centimeters tall. The leaves are small, opposite, and dark green. The most striking feature is the flower spikes that resemble a squirrel's tail - narrow, pink to purple flowers packed tightly in slender spikes. The bloom lasts from summer to fall, giving the plant a long flowering period.

Ideal location

This plant loves full sun to partial shade. In warm areas, some shade may be preferred. Plant in a well-draining location where water does not accumulate. The plant tolerates moderate cold and can grow outdoors in sheltered locations in temperate climates. In very cold regions, greenhouse overwintering is advisable.

Soil

Use well-draining, light soil, preferably mixed with sand or gravel. The plant thrives better in poor soil than in rich, fertilized garden soil. Limestone is accepted. A mixture of garden soil, sand, and perlite works excellently.

Watering

Water moderately. The plant tolerates drought better than excessive watering. In pot culture, water when the top 2 centimeters feel dry. In winter, water very carefully - minimal moisture is sufficient. Avoid wet feet, as this leads to root rot.

Pruning

After flowering, you can lightly cut back the plant to maintain a compact form. Remove dead flowers and weak branches. Excessive pruning should be avoided as it damages flowering.

Maintenance calendar

March to April: Careful pruning if needed. May to September: Regular watering when dry. October to February: Minimal watering, no fertilization. Throughout the year: Check for aphids and spider mites.

Winter hardiness

Colebrookea oppositifolia tolerates moderate frost (-5 to -10 degrees Celsius) if drainage is good. In very cold regions or where frost persists longer, greenhouse overwintering is advisable. Protect from heavy snow and strong wind.

Companion plants

Perfect for alpine troughs and rock gardens. Plant with other drought-tolerant plants such as sedum or sempervivum. In greenhouses, combines well with other alpines.

Closing

Colebrookea oppositifolia is a magnificent plant for alpine gardeners and greenhouse enthusiasts. With minimal care and good drainage, this plant will flower for years. The unique flower spike makes it an attractive addition to any garden. Search online nurseries for seedlings of this special plant.
