Cleome hassleriana for Sale: Pre-Purchase & Growing Guide

• 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 better to buy plant or another option to start from seeds yet more challenging so roots establish in the right conditions.
• Climate fit: Suited to zone 5+ — check it matches your winter lows before planting out.

• 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 0.3–2 m (1–7 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.

• Potting & planting: Plant into fertile, well-draining soil in the ground or a container with good drainage holes.
• Watering: Average amount. Avoid waterlogging, which is the main cause of problems.
• 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.
