About Phlomis-Like Sage

Salvia phlomoides · also called Phlomis-like sage, Woolly-leaf sage · flowering

Salvia phlomoides is a robust, subshrubby perennial native to the Iberian Peninsula and north-west Africa, taking its common name from the strong resemblance its large, felted, grey-woolly leaves bear to plants in the genus Phlomis. It produces whorled spikes of pale lavender to violet flowers on stout stems in summer and thrives in hot, exposed positions with fast-draining, lean soil. Like other Spanish sages, it is highly drought tolerant once established and suffers most from excess winter moisture. ASPCA lists Salvia as non-toxic to cats and dogs.

Plant type: flowering

The reasons phlomis-like sage isn't blooming

Almost every non-blooming phlomis-like 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 phlomis-like 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 phlomis-like sage to flower

Maximise sun. Give phlomis-like 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 phlomis-like sage and get the feeding right with the phlomis-like 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

Phlomis-Like 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.

Phlomis-Like Sage blooming — frequently asked questions

Why won't my phlomis-like sage flower?

Phlomis-Like 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 phlomis-like sage bloom?

Give phlomis-like 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.
