Paradise-tree

Simarouba glauca

The Story

Plant Bio

Simarouba glauca, commonly known as the paradise-tree, is an evergreen tree native to southern Florida, Central America, and the Caribbean. It develops a straight cylindrical trunk with an upright, narrow to spreading canopy of alternate pinnate leaves that emerge bronze-red before maturing to a glaucous blue-green.

This species is dioecious, producing small, yellowish-white flowers in large terminal panicles during spring and summer that attract bees and butterflies. Female trees produce fleshy purple drupes that serve as an important food source for local bird species.

Uses & Benefits:

Ornamental UsesFeatures striking bronze-red new foliage that matures to a glossy, glaucous blue-green, providing year-round canopy interest.
Practical UsesHighly tolerant of coastal salt spray and drought, making it an excellent windbreak or street tree in sandy, calcareous soils.
Ecological BenefitsProvides nectar for native bees and butterflies, while the fleshy purple drupes feed local bird populations.

Planting

How to Grow

  1. Select a planting site in full sun to partial shade with well-drained soil, avoiding areas prone to standing water.
  2. Dig a hole twice as wide as the root ball and of equal depth to ensure the root flare sits flush with the soil surface.
  3. Water deeply immediately after planting to settle the soil, then maintain regular moisture until the root system is established.
  4. Apply a layer of organic mulch around the base to conserve moisture, keeping it several inches away from the trunk.

Pro Tip

Avoid heavy or indiscriminate pruning into old, leafless wood, as this species recovers slowly and produces patchy regrowth.

Keep It Thriving

Care Guide

Do

  • Ensure excellent soil drainage to prevent root rot.
  • Prune young trees early to establish a strong central leader and structural framework.
  • Protect young specimens from freezing temperatures, as the species is highly frost-sensitive.

Don't

  • Do not plant in low-lying, waterlogged, or heavily compacted soils.
  • Do not cut back heavily into old, bare wood during routine maintenance.
  • Do not over-fertilize, as this species is adapted to nutrient-poor sandy and limestone soils.

Common Questions

Paradise-tree questions

What zones can Paradise-tree grow in?

Paradise-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.

When does Paradise-tree bloom?

Paradise-tree 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 Paradise-tree need full sun?

Paradise-tree does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Paradise-tree drought tolerant?

Yes — once established (usually after the first full season), Paradise-tree handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
