Verbena 'Showboat Dark Violet' (Showboat Series)
verbena
A mounding, arching verbena (up to 50cm or 19in long) with clusters of rich violet-purple flowers all summer long. Verbena 'Showboat Dark Violet' from the ‘Showboat’ series is a new broad leaf type of trailing verbena, perfect for pots, containers and hanging baskets.
How to care for Verbena Showboat Dark Violet (Showboat Series):
Grow on under glass until all risk of frost has passed and they can then either be planted outside into a well-prepared bed, or used to fill decorative pots and hanging baskets for the patio (9cm plants don’t need potting on but require initial frost protection).
Pinching out the growing tips will encourage them to become bushier, and feeding with a high-potash fertiliser at regular intervals throughout the summer will promote even more flowers to form.
