Hollyhocks (Alcea rosea), with their predominant stems of brightly coloured, double blooms, stand tall amongst the rest of the garden from spring to summer. They can grow up to a whopping 2 metres in height and are ideal as an annual decorative backdrop along sunny walls and fences.


How to grow hollyhock in a garden

  1. Fill starter pots or trays with Yates Black Magic Seed Raising Mix. Sow Hollyhock Double Elegance or Hollyhock Pink Powderpuff seeds, cover, firm down and water well.
