Flowering Period

Planting and flowering details
  • Planting
  • Hollyhocks are real sun worshippers! An area such as a sunny south facing wall or fence is ideal for this romantic, summer flowering plant. Well-drained, sandy soil will be perfect. Don’t forget to fertiliser and don’t let the plants dry out. Recommended spacing for the young plants is approx. 50 cm apart.
    Hollyhocks next to climbing roses works well. Both varieties have the same requirements and blend together perfectly. Plus with lavender in the vicinity you will have a beautiful result.

  • Care
  • The plants you receive from us will flower during the same year. The Hollyhock is a biennial which means that the plant dies after flowering. When the plant turns to a brownish colour in autumn, you can cut the whole plant.
    The seed pods are very decorative, leave them to ripen and when the pod looks dry the seeds can be used for sowing. Sow the seeds in June in a shady spot. In September, choose the best place in your garden for planting. Cover in winter with a layer of fallen leaves to protect from frost. The plants will bloom the following year from June to July.

  • Specifics
  • The large hollyhock ‘Nigra’ flowers are stunning. The almost black colouring forms a great contrast when planted alongside pink Coneflower (Echinacea purpurea) or the airy inflorescence of Rue (Thalictrum rochebrunianum).
    The tall, sturdy flower stems of the Hollyhock provide a powerful vertical accent in your garden. They look so impressive in the background of the border but the wonderful thing about Hollyhocks is that they look beautiful even in the simplest areas of the garden.
