About Double Angel's Trumpet

Brugmansia suaveolens 'Plena' · also called Double Angel's Trumpet, Double White Angel's Trumpet · flowering

Brugmansia suaveolens 'Plena' is a cultivar of the Brazilian angel's trumpet, notable for its spectacular double or semi-double pendulous white trumpets with an intensely sweet evening fragrance. It grows vigorously and flowers prolifically from summer through autumn. All parts are severely toxic. An impressive patio or conservatory specimen.

Plant type: flowering

Watch for — Lack of double flowers or reverting: Cuttings taken from vigorous basal water shoots can sometimes revert to single flowers; propagate from mature, branching wood above the first Y-fork to preserve the double-flowered trait.

The reasons double angel's trumpet isn't blooming

Almost every non-blooming double angel's trumpet 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 double angel's trumpet 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 double angel's trumpet to flower

Maximise sun. Give double angel's trumpet 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 double angel's trumpet and get the feeding right with the double angel's trumpet 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

Double Angel's Trumpet 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.

For everything else this plant needs day to day, see the full double angel's trumpet care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Double Angel's Trumpet blooming — frequently asked questions

Why won't my double angel's trumpet flower?

Double Angel's Trumpet 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.
