Verbena Bonariensis

Dramatic, tall border plant with rich purple flower clusters. Hardy with some protection.

How to Sow and Grow

  • Sow indoors, January-April, to flower the same year, 0.5cm (¼”) deep, in trays of compost.
  • Water well and place in a greenhouse or on a warm, kitchen windowsill.
  • A temperature of 20-25°C (68-77°F) is ideal.
  • Keep moist.
  • Seedlings usually appear in 21-35 days.
  • If germination is slow or erratic, place the tray in a refrigerator or outside for 1-2 weeks, then return to the warmth.
  • Transplant seedlings to 7.5cm (3″) pots of compost, when large enough to handle.
  • Always hold by a leaf, never by the stem.
  • Gradually accustom young plants to outside conditions (avoid frosts), before planting out into well-drained soil, May-June, 45cm (18″) apart, when frosts are over.
  • Flowers: July to October.
