Utricularia uniflora · also called Single-flowered bladderwort, Single bladderwort · flowering
Utricularia uniflora is a small terrestrial bladderwort native to the east coast of Australia, particularly New South Wales and Tasmania, where it grows in bogs, seeping rock faces, and mossy stream-bank margins at low to moderate altitudes. Its name reflects the characteristic of typically bearing only one flower per scape — a mauve to lilac bloom with distinctive yellow and white ridges on the lower lip. It is a seasonally active species, blooming in spring and summer, and is best grown in cool, permanently moist, nutrient-poor conditions. Utricularia is not listed in the ASPCA database; classified as mildly-toxic as a precaution.
Plant type: flowering
The reasons single-flowered bladderwort isn't blooming
Almost every non-blooming single-flowered bladderwort 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 single-flowered bladderwort 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 single-flowered bladderwort to flower
- Maximise sun. Give single-flowered bladderwort 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 single-flowered bladderwort and get the feeding right with the single-flowered bladderwort 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
Single-Flowered Bladderwort 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 single-flowered bladderwort care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Why won't my single-flowered bladderwort flower?
Single-Flowered Bladderwort 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 single-flowered bladderwort bloom?

When does single-flowered bladderwort normally bloom?
Single-Flowered Bladderwort flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.
What should I do with single-flowered bladderwort after it flowers?
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.
What is the single biggest mistake stopping single-flowered bladderwort flowering?
Feeding single-flowered bladderwort a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.
