Gunnera 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 so roots establish in the right conditions.
• Climate fit: Suited to zone 6+ — 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 1–3.5 m (3–11 ft); it also does well as a container houseplant in bright light.
• Light mapping: Match your site to its needs — full sun to full 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: Keep consistently moist in growth. Don’t let it dry out during active growth.
• Light: Position in full sun to full 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.

Gunnera earns its place by offering decorative foliage. With a long season of interest from spring to summer, it works well in beds, borders, patio pots or as an indoor specimen. You may also see it sold as Giant Rhubarb.
