Setup, Compatibility & Care

  1. Sowing Seeds: Sow Verbena bonariensis seeds from February to April on the surface of a good, free-draining, damp seed compost and lightly cover with vermiculite.

  3. Outdoor Planting: When all risk of frost has passed, gradually acclimatize Verbena plants to outdoor conditions before transplanting them into any well-drained soil in full sun. Space plants 30cm (12") apart.
  4. Watering and Feeding: Feed and water frequently throughout the summer to ensure an endless supply of flowers.
  5. Deadheading: Verbena flowers do not require deadheading.
  6. Compatibility: Verbena bonariensis is compatible with a wide range of plants, including ornamental grasses, Echinacea, and Rudbeckia. It thrives in well-drained soil and full sun, ensuring compatibility with other sun-loving perennials.
