Grape hyacinths are small plants, usually not much more than 10cm tall, and produce blue or purple grape-like flowers. One grape hyacinth doesn’t look like much but in a mass planting they can be a knockout. Planted at the base of deciduous trees and shrubs and left to naturalise, they can have a stunning effect.
Plant in autumn.
Plant in a well-drained soil, enriched with organic matter at a depth of about 8cm. Water well at planting. Subsequent water is needed only if soil dries out.
As clumps thicken over time fertilising becomes important.
Bait for snail and slugs during the growing period.
