Moonbeam Coreopsis, or tickseed as it is sometimes called, is one of the threadleaf varieties of coreopsis. It is an herbaceous perennial, meaning the above-ground portion of the plant dies back to the ground during the winter months while it hibernates.

Moonbeam is a little more compact than other threadleafs, topping out at around 2’ tall and wide. The flowering is no less brilliant, though. From June through September or even October the plant is smothered in flowers.

The flowers are a buttery yellow with a darker yellow in the center. They appear singly in loose clusters atop each stem. The stems tend to be reddish-brown, especially at the base of the plant and at the tips. Thin, willowy leaves are green. Moonbeam is a fast grower, reaching its full size in a couple of seasons.

Moonbeam will spread by underground rhizomes. You can divide it every couple years if you’d like. This will help keep it in the place and size you want it.

Moonbeam was the 1992 Perennial Plant of the Year. It has grown and performed consistently well all over the United States and Canada.


Clipping off the faded flowers will help to encourage more blooming. My experience, though, is that this is not really necessary. Moonbeam is a prolific bloomer. The one time you might give it a trim is in late August, only if it seems to be slowing down. Just take the hedge trimmers and cut the tops off for an even buzz cut. Within two weeks it will be full of flowers once again.

Grow it in a sunny spot. Once established, it is somewhat drought-tolerant. It is also a great attractor of bees and butterflies. In fact, they go nuts over this plant. Place them near vegetable crops to ensure a steady supply of busy polinators.

Uses: Cut flowers, edging, sunny border, containers, mass plantings. Try planting three to five of these in a bed interspersed with other 2-3’ tall perennials or shrubs. The repeating pattern of these bright masses of flowers will really stand out! They would make a fine neighbor with potentilla because their flowers are somewhat similar in shape and they have a similar bloom period, and both are prolific bloomers. Their pale yellow flowers also go well with darker-colored neighbors such as Crimson Pygmy Barberry or Black Mondo Grass.

Problems: Nah, this is an easy one to grow. If you can’t grow these your thumb is worse than brown. Ideal for beginners.
