Coreopsis lanceolata aka Coreopsis

Taxonomy

Coreopsis lanceolata, also known as lanceleaf coreopsis, lanceleaf tickseed, lance-leaved coreopsis, or sand coreopsis, is a North American species of tickseed in the Asteraceae family. It grows in small clumps, but can form extensive colonies, reaching heights of 1-2 1/2 feet. The leaves are 3-4 inches long, opposite, and sometimes alternate near the top. Some leaves are deeply cut, almost forming 3 leaflets. The yellow flower heads are 1-1 1/2 inches across, with distinct yellow center or disk flowers and 4-lobed ray flowers attached just below them. Lanceleaf Tickseed is native to Southeastern Canada to the Central and Eastern United States. It is a relatively rare houseplant that thrives with regular watering and should be placed in direct light, less than 1 foot from a window. The plant prefers well-draining soil and doesn't need added fertilizers if repotted each time it doubles in size.

How to care for Coreopsis

Difficulty

If you're looking for a plant that offers a moderate level of challenge, Coreopsis is a great choice to test your gardening skills.

Water

Coreopsis should be watered regularly, allowing the soil to dry out between waterings.

Soil

Coreopsis loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Coreopsis requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Garden Coreopsis is always in the right place to thrive.

Dormancy

During the cold period, it is common for Coreopsis to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.

Toxicity

Ploi lacks confirmed information on the toxicity of this plant. If you, a relative, or your pet accidentally consume plant material with unknown toxicity, it's best to consult a medical expert.

Fertilizer

The Coreopsis should be repotted when it has doubled in size or annually, whichever comes first. Providing fresh potting soil with all the essential nutrients each year ensures the plant's well-being, eliminating the need for fertilizer. Remember, plants derive their energy from the sun and not fertilizer.

Growth-pattern

The Coreopsis is characterized by clumping growth, with new shoots emerging from the soil around the primary plant.
