The best true-blue Verbena every grown on T&M trials. Clusters of rich blue flowers against deep green foliate, look spectacular in borders or containers. An outstanding garden performer with good mildew resistance, but best of all, is its sweet evening fragrance.

Height: 25-30cm (10-12in).

Sow February to April. Sow in pots or trays of moist seed compost. Do not cover the seed. Place in a propagator or warm place, and keep at a constant temperature of between 24-27C (75-80F). After sowing, do not exclude light as this helps germination. Germination will usually take 14 to 21 days. Keep the compost on the dry side at all times, and water lightly as seedlings emerge.

When large enough to handle, transplant seedlings into 7.5cm (3 inch) pots or trays. Gradually acclimatise young plants to outdoor conditions for 10 to 15 days before planting out after all risk of frost, 30cm (12 inches) apart, or transplant into containers

For best results, provide any ordinary, well-drained soil in full sun.
