About Long-stamened Sage

Salvia exserta · also called Long-stamened sage, Extended-stamen sage · flowering

Salvia exserta is a rare South African sage named for its conspicuously long, exserted stamens that protrude far beyond the tubular rose-pink to magenta flowers, creating a striking display that attracts long-tongued sunbirds and insects in its native habitat. It is an upright, tender perennial that blooms in summer and autumn, best grown in pots that can be overwintered frost-free. Plant in full sun with very free-draining soil to prevent rot. Salvia is listed by the ASPCA as non-toxic to cats and dogs.

The reasons long-stamened sage isn't blooming

Almost every non-blooming long-stamened sage 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 long-stamened sage 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 long-stamened sage to flower

Maximise sun. Give long-stamened sage 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 long-stamened sage and get the feeding right with the long-stamened sage 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

Long-stamened Sage 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 long-stamened sage care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Long-stamened Sage blooming — frequently asked questions

Why won't my long-stamened sage flower?

Long-stamened Sage 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 long-stamened sage bloom?

Give long-stamened sage 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.
