Harvest Tips
Leaves can be harvested year-round for tea, though traditional harvesting occurs in late spring/early summer when leaves are most aromatic. Cut fresh stems and hang-dry in shade. For ornamental purposes, flowers can be cut for fresh arrangements in spring. Seeds can be collected by allowing capsules to dry and split naturally on the plant.
