Agapanthus 'Windsor Grey'
- available to order from autumn
- 9cm pot
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
- Position: full sun
- Soil: fertile, moist, well-drained soil (or John Innes no. 3 compost for containers)
- Rate of growth: average
- Flowering period: July to September
- Hardiness: frost hardy (may need some protection in winter)
Tolerant of drought once established, this decorative perennial produces large heads of pale, grey-blue flowers from mid-to-late summer. Agapanthus make fine specimens in a pot, where their architectural silhouette can best be appreciated - or dot them through the summer border.
- Garden care: Apply a balanced liquid fertiliser monthly from spring until flowering. Towards the end of September ease back on the watering and feeding of plants in containers to allow the foliage to toughen up. In cold areas, protect the crown of the plant with a deep, dry mulch to protect them from hard frosts, or grow in a pot so they can be overwintered in an unheated greenhouse. Divide plants that have become too big in spring, but remember you will often get more flowers when the roots are constricted.
