Verbena bonariensis - 200 seeds

The Verbena bonariensis is an autumnal God-send, and I mean that for two specific reasons. It comes in to full flower when most other plants are busy producing seeds, and it is an excellent source of nectar for those pollinating insects brave enough to venture into the cold and blustery autumn weather.

As ideally suitable as it appears to be in our northern European gardens, Verbena bonariensis is a long way from home. This tall and slender-stemmed perennial is in fact a native of tropical South America where it grows throughout most of the warm regions, from Colombia and Brazil to Argentina and Chile.

It can grow to an impressive 6 foot tall, and can spread up to 3 foot wide.

Sow in trays, pots, etc of good seed compost in a propagator or warm place to maintain an optimum temperature of 60-65F (15-18C). Sow in well drained compost, just covering the seed with compost. Sowing Time: February to March. Very slow and irregular germination. Keep the seed compost cool and moist but not saturated at all times.
Transplant seedlings when large enough to handle into 7.5cm (3in) pots. Acclimatise young plants to outdoor conditions before planting out 60cm (24in) apart in full sun.

Plant in ordinary garden soil.
