Care
Watering
Teesdale prefers rather dry conditions once established. Water moderately in spring during growth, then gradually reduce. Avoid excess moisture which could promote root rot, particularly in winter.
Exposure
Place this plant in full sun or partial shade. It appreciates abundant light for generous flowering and compact growth. A sunny exposure will also strengthen its hardiness.
Soil Preparation
Prepare well-drained, light soil that is rather chalky or neutral. If your soil is heavy or clayey, improve it with sand or gravel. Avoid rich and overly moist soils which stimulate excessive growth at the expense of flowering.
Fertilizer
Teesdale is undemanding when it comes to nutrients. A moderate application of balanced fertilizer in early spring is more than sufficient. Poor soils suit it well and promote more abundant flowering.
Pruning and Cleaning
Remove faded flowers regularly to prolong flowering and stimulate new flower production. At the end of the season, eliminate dried parts. Light pruning after flowering maintains a harmonious, bushy shape.
Diseases and Pests
This hardy plant resists common garden pests and diseases well. Be careful with stagnant moisture which can cause rot. Ensure optimal drainage and good air circulation.
Did you know?
Teesdale owes its scientific name to British botanist John Tees (1777-1846), who collected herbarium specimens during his travels in England. This small spring-flowering crucifer was long considered a ruderal species of roadsides before being rediscovered and appreciated by gardeners for its delicate white and pink flowers that illuminate rock gardens and mountain gardens in early spring.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
