The Story
Plant Bio
Harpullia pendula, the tulipwood, is an evergreen Australian tree reaching twenty to thirty-three feet in garden cultivation, forming a dense, symmetrical, and rounded canopy. The alternate, compound leaves are glossy green with soft, copper-pink or fawn-colored new growth, producing pendulous sprays of small, greenish-yellow flowers from spring to summer.
The species is highly resilient to urban pollution and coastal salt air, making it an exceptional street or shade tree for warm, frost-free climates. After flowering, it drops decorative capsules and small seeds that can accumulate on the ground and attract ants.

Planting
How to Grow
- Plant in a full sun to partially shaded location with well-drained soil, as the roots are highly intolerant of prolonged waterlogging.
- Apply a balanced fertilizer or compost at planting to assist with establishment, watering thoroughly to settle the soil.
- Provide regular water during the first few seasons; once established, the tree exhibits high drought tolerance.
- Protect young trees from even light frosts, though established specimens can tolerate mild, occasional cold spells.
Pro Tip
Perform formative pruning early to establish a single, strong central leader, as branches naturally emerge low on the trunk. Avoid aggressive pruning into old, leafless wood, which limits recovery.

Care Guide
Do
- Prune young trees early to establish a single central trunk.
- Ensure the planting site has excellent drainage to prevent root rot.
- Sow fresh seeds immediately after harvest, as they rapidly lose viability when dry.
Don't
- Do not prune aggressively into old, leafless wood.
- Do not allow the soil to remain waterlogged or poorly drained.
- Do not over-fertilize established trees, as they require minimal ongoing feeding.

Common Questions
Tulipwood questions
What zones can Tulipwood grow in?
Tulipwood is hardy in USDA Zone 10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
When does Tulipwood bloom?
Tulipwood typically blooms in spring through summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Tulipwood need full sun?
Tulipwood does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Tulipwood drought tolerant?
Yes — once established (usually after the first full season), Tulipwood handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
