Expert tips
The key tip
Plant it in well-draining soil (add gravel if clay), it hates stagnant winter moisture. Pinch young stems in May to make it bushier rather than leggy.
The common mistake
Most gardeners overwater it and put it in soil that's too rich: it rots at the roots in winter and refuses to flower abundantly.
The pro's trick
Sow it in pots from March in an unheated cold frame: young plants get much stronger and will flower more densely in the first year.
Seasonal watch
In wet autumn, watch for powdery mildew on foliage at the base of the plant; lightly aerate around it in September to prevent basal rot.
Care
Exposure
Plant your globularia in full sun for generous flowering and compact growth. It tolerates light partial shade but flowers less abundantly. Avoid heavily shaded areas that promote legginess.
Watering
Water moderately after planting to establish the root system. Once well established, globularia is very tolerant of drought thanks to its xeophytic nature. Reduce watering in winter and avoid excessive moisture, particularly in heavy soil.
Soil
Prefer very well-drained, light soil that is preferably chalky or neutral. Improve heavy soils by incorporating coarse sand or gravel. Avoid compact and permanently humid soils.
Pruning and maintenance
Pruning is not really necessary. You can lightly cut back after flowering to maintain a dense and compact habit. Remove any dried parts in late winter.
Fertilizer
Globularia is not demanding in nutrients and thrives in poor soils. Avoid generous fertilizer applications that would promote growth at the expense of flowering. A light annual application in spring is more than sufficient.
Diseases and pests
Very hardy and robust, globularia presents few health problems. Excess stagnant moisture can occasionally promote fungal development. Ensure optimal drainage to prevent any issues.
Did you know?
The heartleaf globularia owes its scientific name 'Globularia' to the shape of its inflorescences: small balls or pompoms of blue-violet flowers that attract bees and butterflies. Once used in alpine herbalism for its supposed virtues, it remains an excellent plant for Mediterranean rock gardens that thrive in difficult conditions.
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.
