About Meadow Blazing Star

Liatris ligulistylis · also called meadow blazing star, Rocky Mountain blazing star · flowering

Meadow blazing star is a North American prairie perennial famous as a monarch magnet, its rose-purple button flowers among the most attractive of all Liatris to migrating butterflies. Tall flower spikes rise from a corm above grassy foliage in late summer. It prefers full sun and moist-to-medium, well-drained soil, tolerating more moisture than its dry-prairie relatives.

Plant type: flowering

The reasons meadow blazing star isn't blooming

Almost every non-blooming meadow blazing star traces back to one of these, roughly in order of how common they are:

  1. Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
  2. Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
  3. The plant has not been deadheaded, so it stops flowering once it sets seed.
  4. Irregular watering — drought or waterlogging at the budding stage makes buds abort.
  5. It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding meadow blazing star 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 meadow blazing star to flower

  1. Maximise sun. Give meadow blazing star the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
  2. Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
  3. Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
  4. 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 meadow blazing star and get the feeding right with the meadow blazing star 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

Meadow Blazing Star 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.
