Thompson & Morgan National Trust Range Verbena bonariensis 200 seed

A very popular perennial, producing robust plants with masses of wiry stems topped by attractive clouds of eye-catching, rosy lavender blooms. Ideal interplanted amongst other perennials, adding height and a tranquil feel to borders.

Sow seed onto the surface of a good, free-draining, damp seed compost. Apply a very fine sprinkling of dry vermiculite. Place in a propagator or seal container in a polythene bag at a temperature of 24-27°C (75-80°F) until after germination which takes 14-21 days. Do not exclude light as this helps germination. Keep compost on the dry side then water lightly as seedlings emerge.
