Plant Information

Top Tips

Keep plants well-watered when in full growth to help produce the tallest spires of bloom

Care Guide

  • Grow in well-drained, moderately fertile soil in full sun. If growing in an exposed location, plants may need staking.
  • A perennial plant, this black hollyhock dies back to ground level over winter, with fresh, new growth emerging in the spring.
  • Remove flowering stems when blooms fade and in autumn cut the plants back to 15cm (6in) from the ground.
  • Before planting, prepare the soil by digging over and removing any weeds. Incorporate some well-rotted manure to enrich the soil if necessary.
  • When planting a number of perennials, arrange them on the surface so you can see how they will look before planting.
  • Individually knock out each plant from its container. Look at the roots – if they are circling around the compost, it is best to tease them out. To do this, push your fingers into the rootball along the bottom edge and pull. Do this in a couple of places. This should encourage the roots to spread into the surrounding soil.
  • Next use a trowel or spade to create a hole just deep and wide enough to set in the rootball.
  • The aim is to bury just the roots, leaving the bases of the stems (when in growth in summer) or the shoots (in spring) above ground.
  • Firm back around the soil, using your hand for small clumps and your heel on larger areas.
  • Water in well to settle the soil and prevent desiccation.
