About Pires's Sinningia

Sinningia piresiana · also called Pires's Sinningia · flowering

Sinningia piresiana is a tuberous caudiciform gesneriad from Brazil, valued among collectors for its silvery, white-haired foliage arranged in a whorl of six leaves atop a compact stem, and its cherry-pink tubular flowers with prominent crimson stripes towards the throat. In general habit it resembles the closely related S. canescens and S. leucotricha. After flowering the plant goes dormant, dying back to the tuber until conditions trigger regrowth. The ASPCA lists the Sinningia genus as non-toxic to cats and dogs; this species is not individually verified.

Plant type: flowering

The reasons pires's sinningia isn't blooming

Almost every non-blooming pires's sinningia 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 pires's sinningia 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 pires's sinningia to flower

Maximise sun. Give pires's sinningia 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 pires's sinningia and get the feeding right with the pires's sinningia 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

Pires's Sinningia 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 pires's sinningia care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Pires's Sinningia blooming — frequently asked questions

Why won't my pires's sinningia flower?

Pires's Sinningia 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 pires's sinningia bloom?

Give pires's sinningia 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.
