Giant hyssop makes a lovely addition to a cottage garden planting scheme. It makes an attractive addition to borders or wildlife gardens, being highly attractive to pollinating insects (on the RHS Perfect for Pollinators list). Its minty fragrance adds a lovely scent to the garden, so try planting where you will benefit from its fragrance.

Harvesting
Leaves can be picked as soon as they appear, although for a healthy plant it is best to let it become fully established. Flowers may be harvested as soon as they appear. Whole stems may be cut out, and both leaves and flowers from that stem can then be used.
