About Pink mountain heather

Phyllodoce empetriformis · also called Pink mountain heather, Red mountain heather · flowering

Pink mountain heather is a spreading alpine subshrub native to western North America, from Alaska to California and the Rocky Mountains, bearing abundant rose-pink to magenta urn-shaped flowers in late spring. Its dense, needle-like evergreen foliage forms attractive mats suited to acidic cool rock gardens, and it is among the most ornamental of the mountain heathers.

Plant type: flowering

Watch for — Sparse flowering: Insufficient winter cold or excessive shade can reduce flower production. Ensure at least some direct sunlight and allow plants to experience natural cold winters. In very mild regions, flowering is often poor regardless of other conditions.

The reasons pink mountain heather isn't blooming

Almost every non-blooming pink mountain heather 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 pink mountain heather 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 pink mountain heather to flower

Maximise sun. Give pink mountain heather 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 pink mountain heather and get the feeding right with the pink mountain heather 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

Pink mountain heather 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 pink mountain heather care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Pink mountain heather blooming — frequently asked questions

Why won't my pink mountain heather flower?

Pink mountain heather 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.
