A perennial which brings height, movement and beautiful late-summer colour to the garden. A hardy North American wildflower producing slender, upright spikes covered in tiny violet-blue flowers, opening gradually from the bottom upwards. Its distinctive branching stems create an almost candelabra-like appearance, with delicate flower spikes rising above attractive green foliage. Reaching heights of approximately 100–130 cm, it creates a lovely haze of colour when planted in groups.
Flowering from July through to September, Verbena hastata is particularly suited to naturalistic planting schemes, cottage gardens and prairie-style borders. Its nectar-rich flowers attract bees, butterflies and other pollinators, while the tall, slender stems provide structure without overwhelming neighbouring plants. A hardy perennial which returns year after year, combining beautifully with ornamental grasses and other late-flowering perennials.
When to Sow: Feb–Apr & Sep
HOW TO SOW:
Sow seeds onto moist compost and cover lightly with fine grit to approximately their own depth. Keep at 15–20°C to encourage germination, maintaining even moisture without waterlogging. Germination can be slow and irregular, and some seeds may not emerge in their first year. If germination does not occur, place the seed tray in a sheltered outdoor position to experience natural winter chilling, as some seeds may only germinate the following spring. Once seedlings are large enough to handle, transplant into individual pots and grow on until well established before planting outside
