The Story
Plant Bio
Tabernaemontana litoralis, commonly known as the milky way tree, is a large evergreen tropical shrub or small tree distinguished by its dichotomous branching and glossy, intense dark green foliage. The plant produces an abundant, highly toxic milky latex sap throughout its stems and leaves.
The highly fragrant, pure white flowers feature a contrasting yellow throat and a distinct salverform shape with overlapping lobes. Borne in small terminal clusters of two to six, these blooms release a sweet, musky scent continuously throughout the spring and summer.

Planting
How to Grow
- Select a planting site that receives full sun to partial sun, ensuring it is completely free from standing water.
- Dig a hole twice the width of the root ball and backfill with standard garden loam, amending if necessary to guarantee high drainage.
- Water regularly during the establishment phase and during dry spells to support continuous flowering.
- Apply a balanced, slow-release fertilizer during the active spring and summer growing seasons.
Pro Tip
Never cut back hard into old, leafless wood where buds cannot break; instead, prune lightly after flowering to shape the canopy.

Care Guide
Do
- Wear gloves when pruning to avoid skin irritation from the toxic milky sap.
- Provide full sun to maximize flower production and maintain a compact growth habit.
- Ensure the planting medium is highly permeable and drains rapidly.
Don't
- Do not plant in heavy clay or low-lying areas prone to waterlogging.
- Do not prune hard into old, leafless wood where new buds cannot break.
- Do not allow the plant to experience frost, as it is a tender tropical species.
