About Candelabra Sage

Salvia candelabrum · also called Candelabra sage, Candelabrum sage · flowering

Salvia candelabrum is a tall, branching, semi-evergreen perennial native to the mountains of southern Spain, particularly the Sierra Nevada. It produces dramatically candelabra-like branched stems bearing whorls of large, two-lipped, violet-blue flowers with a white lower lip from midsummer through to early autumn, making it one of the showiest of the hardy Spanish sages. It requires good drainage and full sun and is borderline hardy in the UK, benefiting from a sheltered position or a protective dry mulch in colder gardens. ASPCA lists Salvia as non-toxic to cats and dogs.

Plant type: flowering

Watch for — Aphid attack on new growth: Soft spring shoots can attract aphid colonies; check new stems regularly and blast off with water or apply an insecticidal soap spray, avoiding open flowers that attract pollinators.

The reasons candelabra sage isn't blooming

Almost every non-blooming candelabra 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 candelabra 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 candelabra sage to flower

Maximise sun. Give candelabra 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 candelabra sage and get the feeding right with the candelabra 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

Candelabra 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 candelabra sage care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Candelabra Sage blooming — frequently asked questions

Why won't my candelabra sage flower?

Candelabra 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 candelabra sage bloom?

Give candelabra 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.
