Pre-purchase considerations

  • How it’s sold: Buying an established plant gives the fastest, most reliable start; growing from seed is possible but slower and less predictable.
  • Planting window: Plant in spring to autumn so roots establish in the right conditions.
  • Climate fit: Suited to zone 6+ — check it matches your winter lows before planting out.

Growing tips before you buy

  • Cold protection: Know your first-frost date and have shelter ready for young plants in a cold snap.
  • Space & siting: Allow for a mature size of about 0.7–1.2 m (2–4 ft); it also does well as a container houseplant in bright light.
  • Light mapping: Match your site to its needs — full sun to partial shade. Give the brighter end for the best flowering.
  • Soil readiness: Prepare fertile, well-draining soil before planting; a free-draining mix prevents root rot.

Cultivation & care standards

  • Potting & planting: Plant into fertile, well-draining soil in the ground or a container with good drainage holes.
  • Watering: Let the soil dry between waterings. Avoid waterlogging, which is the main cause of problems.
  • Light: Position in full sun to partial shade for healthy growth.
  • Feeding: Feed through the growing season with a balanced fertilizer to support steady growth.
  • Upkeep: Tidy spent growth and watch for the usual pests; good airflow keeps foliage healthy.
