Verbena bonariensis 600 seeds


A very useful plant for the border, producing its heads of bright blue or rose-lavender flowers from June until October. If you sow the seeds early, it will flower the same year in the summer. Particularly effective if grown in a mass. May need winter protection in cold districts. Flowers July - September. Clump forming perennial with small lilac-purple florets on tall slender stems. Can flower in first season from an early sowing.

Sow indoors in seed compost. Just cover the seed lightly with compost. Propagate at about 20°C. The germination can be very slow 20- 90 days and needs no light. 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 to 8cm pots. Acclimatise and plant out 60cm apart in full sun.

Grow in a larger base for best effect. Pinch back when first planted to encourage branching. Water deeply to encourage root growth. May require a frame on which to grow.

If sown early it will flower in the same year. Cut and come again variety. Cut flowers regularly to encourage growth and to prolong flowering window. Take off the spent flower heads if you do not want the plant to self-seed. Cut down in spring once new shoots emerge at the base.
