Verbena Bonariensis

Description

Dramatic, tall border  ( up to 180cm ) plant with rich purple flower clusters. A magnet for butterflies and bees. Possibly one of the most valuable summer flowering plants. This beauty from Brazil threads its stiffly upright stems through other perennials, floating hundreds of amethyst color spheres loftily throughout your garden. Ideal for the back of the border where it softens the outline of its garden companions.

These perennial seeds germinate very irregularly over a long period. Lower temperatures of less than +5°C [41°F] are very effective. Sow indoors. Sow into moist well-drained seed compost. Just cover the seed with compost. Propagate at 18-21°C. This can have very slow and erratic germination(14-90 days). Germination occurs in the dark. Keep the soil moist but not saturated. Once germinated remove the cover to prevent damping off. Reduce temp. to 15°C(windowsill ideal). Transplant seedlings when large enough to handle 8cm pots.
