About Bladder Cherry
Physalis alkekengi var. franchetii · also called Bladder Cherry, Chinese Lantern · flowering
Bladder Cherry is a large-fruited variety of Physalis alkekengi selected for its especially showy, oversized orange-red papery calyces. It is grown primarily as an ornamental for autumn and winter dried arrangements. Extremely cold-hardy and vigorous, it spreads by rhizomes. As with the species, unripe berries and green parts are toxic to pets.
Plant type: flowering
The reasons bladder cherry isn't blooming
Almost every non-blooming bladder cherry 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 bladder cherry 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 bladder cherry to flower
- Maximise sun. Give bladder cherry 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 bladder cherry and get the feeding right with the bladder cherry 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
Bladder Cherry 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 bladder cherry care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Why won't my bladder cherry flower?
Bladder Cherry 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.
