Agapanthus Dark Silk | 9cm Pot

A dark blue flowering herbaceous perennial . 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 August Hardiness: hardy (may need protection from frost in winter) A deciduous clump-forming perennial, ‘Dark Silk’ has intense purple buds which open to deep blue flowers. The rich green shade of the broad foliage creates a wonderful contrast. If you’re looking for continuity of display for your borders, these agapanthus can be used to great effect following allium varieties and Nectaroscordum siculum. 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 in spring. Divide plants that have become too big in spring, but remember you will often get more flowers when the roots are constricted.
