Coreopsis verticillata · also called Moonbeam Coreopsis, Whorled Tickseed · flowering

Coreopsis verticillata 'Moonbeam' is a long-blooming prairie perennial producing a months-long display of soft, pale yellow daisy-like flowers from early summer to autumn above delicate, thread-like foliage. It is highly drought-tolerant once established, requiring little maintenance. Considered non-toxic to pets based on ASPCA data for Coreopsis.

Plant type: flowering

The reasons threadleaf tickseed 'moonbeam' isn't blooming

Almost every non-blooming threadleaf tickseed 'moonbeam' 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 threadleaf tickseed 'moonbeam' 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 threadleaf tickseed 'moonbeam' to flower

Maximise sun. Give threadleaf tickseed 'moonbeam' 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 threadleaf tickseed 'moonbeam' and get the feeding right with the threadleaf tickseed 'moonbeam' 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

Threadleaf Tickseed 'Moonbeam' 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 threadleaf tickseed 'moonbeam' care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.
