The Story
Plant Bio
Clusia rosea, the autograph tree, is a dense, broad-canopied evergreen tree or large shrub native to the Caribbean and southern Florida. It often begins life as a hemi-epiphyte, sending thick aerial roots down from branches to anchor in the soil, and bears distinctive leathery, paddle-shaped leaves.
The rigid, dark green foliage retains permanent marks when scratched, allowing writing to remain visible on the leaf surface. In summer, it produces thick-petaled, cup-shaped white or pale pink flowers with a central ring of yellowish-red resin.

Planting
How to Grow
- Select a planting site in full sun to partial shade with sandy, loamy, or rocky limestone soil that drains rapidly.
- Dig a hole twice as wide as the root ball and set the plant at the same depth it was growing in the container.
- Water deeply immediately after planting, then allow the soil to dry out completely before watering again.
- Apply a balanced, slow-release fertilizer sparingly during the active spring and summer growing seasons.
Pro Tip
Provide exceptionally sharp drainage to prevent root rot, as this species utilizes CAM photosynthesis and is highly drought-tolerant once established. Avoid pruning harshly into old, leafless wood, which lacks the capacity to regenerate new shoots.

Care Guide
Do
- Allow the soil to dry out completely between waterings to prevent root rot.
- Grow as an indoor container plant if winter temperatures drop below 32 degrees Fahrenheit.
- Wear gloves when pruning to avoid contact with the irritating, sticky latex sap.
Don't
- Do not overwater or plant in heavy, poorly-drained clay soils.
- Do not prune heavily into old, bare wood that lacks active foliage.
- Do not plant outdoors in regions prone to frost, as freezing temperatures cause severe tissue damage.

Common Questions
Autograph Tree questions
What zones can Autograph Tree grow in?
Autograph Tree 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.
Is Autograph Tree deer resistant?
Not reliably. Deer may browse Autograph Tree, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Autograph Tree bloom?
Autograph Tree typically blooms in summer through autumn. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Autograph Tree need full sun?
Autograph Tree does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Autograph Tree drought tolerant?
Yes — once established (usually after the first full season), Autograph Tree handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
