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 end of the winter to spring so roots establish in the right conditions.
  • Climate fit: Suited to zone 8-11 — 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 0.3–1.5 m (1–5 ft); give it room to reach full size or choose a compact spot/pot.
  • Light mapping: Match your site to its needs — full sun. Give the brighter end for the best flowering.
  • Soil readiness: Prepare rich, acidic and moist soil before planting; slightly acidic soil that stays evenly moist.
