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 early spring or autumn (in hot area) when buy seeds so roots establish in the right conditions.
  • Climate fit: Suited to zone 3-11 — 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: give it room to reach full size or choose a compact spot/pot.
  • Light mapping: Match your site to its needs — full sun to partial shade. Give the brighter end for the best flowering.
  • Soil readiness: Prepare well-draining loam soil before planting; moist but never waterlogged.

Cultivation & care standards

  • Potting & planting: Plant into well-draining loam soil in the ground or a container with good drainage holes.
  • Watering: Keep consistently moist in growth. Don’t let it dry out during active growth.
  • Light: Position in full sun to partial shade for healthy growth and the best flowering.
  • Feeding: Feed through the growing season with a balanced fertilizer, switching to a bloom feed as buds form.
  • Upkeep: Tidy spent growth and watch for the usual pests; good airflow keeps foliage healthy.
