About Primulina 'Patina'

Primulina 'Patina' · also called Patina Primulina · flowering

Primulina 'Patina' is a compact rosette gesneriad grown for its thick, patterned silver-and-green quilted leaves as much as its lavender tubular flowers. Slow, tidy and long-lived, it tolerates lower light and less-frequent watering than many gesneriads, making it an easygoing windowsill or terrarium plant. Not individually listed by the ASPCA.

Plant type: flowering

Watch for — Slow or no flowering: Low light or under-feeding limits blooms on this naturally slow grower. Brighten the position and apply a dilute feed in the growing season.

The reasons primulina 'patina' isn't blooming

Almost every non-blooming primulina 'patina' 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 primulina 'patina' 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 primulina 'patina' to flower

Maximise sun. Give primulina 'patina' 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 primulina 'patina' and get the feeding right with the primulina 'patina' 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

Primulina 'Patina' 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.

Why won't my primulina 'patina' flower?

Primulina 'Patina' 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.
