Verbena bonariensis Cut Flower Information
|Seed Quantity:||Approx. 300 seeds per pack.|
|When to Sow:||February-April.|
|Site Conditions:||Sunny, well-drained.|
|How to Sow:||Sow the seeds direct on the surface of free-draining, pre-watered seed compost in plug trays to avoid root disturbance. Cover the seed with a layer of vermiculite and refrain from watering again until the seed has germinated. Cover tray and keep at 18-22°C until germination takes place. Germination can be erratic and may take 2 weeks or more. After 5 weeks ‘pot on’ to individual small pots and then transplant outside when large enough (60cm apart), after a period of ‘hardening off’.|
|Care:||Cut flowers down to ground in autumn and mulch to help through winter. Self-seeds easily so take care if you don’t want lots of little ones. To help it get through winter cover with a thick layer of dry mulch in the autumn, and don’t cut down the flower stems.|
|Flowers:||July to October (until first frosts).|
