Trachelospermum asiaticum · also called Asian star jasmine, Japanese star jasmine · flowering

Trachelospermum asiaticum is a tough evergreen twining climber and groundcover with small, glossy dark leaves and fragrant creamy-yellow pinwheel flowers in summer. Slightly hardier and more compact than its cousin T. jasminoides, it self-clings as it climbs and roots as it spreads. Excellent for fences, low walls or as scented evergreen ground cover.

Plant type: flowering

Watch for — Slow to flower: Young plants and those in shade may take a year or two to bloom well. Give it a sunnier position and be patient while it establishes a strong root system.

The reasons trachelospermum asiaticum isn't blooming

Almost every non-blooming trachelospermum asiaticum traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding trachelospermum asiaticum a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get trachelospermum asiaticum to flower

Maximise sun. Give trachelospermum asiaticum the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for trachelospermum asiaticum and get the feeding right with the trachelospermum asiaticum fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Trachelospermum asiaticum flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

Trachelospermum asiaticum blooming — frequently asked questions

Why won't my trachelospermum asiaticum flower?

Trachelospermum asiaticum blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make trachelospermum asiaticum bloom?

Give trachelospermum asiaticum the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
