Coreopsis tripteris belongs to the Aster family, Asteraceae, and genus Coreopsis.
Gold Standard coreopsis is its famous cultivar. This cultivar is made by the Mt. Cuba Center by seeds obtained from Alabama. It combines all the attributes of the typical species with a smaller habit, featuring sturdy stems that never flop. This means that the flowers of Gold Standard coreopsis are bunched and presented in a better way as compared to the ordinary species.
Coreopsis tripteris Care
This is a hardy plant that is easy to grow and care for. It is unfussy, long-lived, and stays in bloom for extended periods. The following are the optimal conditions it needs.
Light & Temperature
Coreopsis tripteris is a true sun lover. It enjoys full sun and partial shade, so look for a sunny spot to grow it in your garden. It is sturdy and heat-tolerant with USDA Hardiness Zones 4 through 9.
Water & Humidity
Tall coreopsis is drought tolerant. It has very low watering needs, especially during the colder months of the year. You can water it regularly during the bloom time but refrain from overwatering as it can lead to waterlogged soil.
Soil
This is a hardy plant that thrives well in rocky soils or sandy soil of poor to medium quality. The soil must be well-drained but the soil moisture must remain consistent. This is because in soil with consistent moisture expect fuller and taller plants as compared to plants that are grown in dry soil.
Poorly drained soils will most assuredly kill this drought tolerant plant, so plant in soil that drains well. Dry soil isn’t a problem as long as your tickseed is established.
Fertilizer
This plant does not require fertilizer for growing or blooming its yellow flowers. It grows and flourishes well in poor soil. You can top it off with some compost annually to feed the soil.
Repotting Coreopsis tripteris
In the right growing conditions, this plant can naturalize to form large colonies as it self-seeds abundantly. If you plant it in a pot or borders, plant division will be required every one to two years.
Coreopsis tripteris Propagation
This plant generally propagates through seeds. It self-seeds vigorously like other members of the genus Coreopsis, which makes it the perfect plant for naturalization. Mature plants can also be propagated through division. Simply dig up the mature plants, divide the stems, and replant them.
Pruning Coreopsis tripteris
Pruning is good as it encourages additional bloom. Deadhead the old flower head before or after the flowering season to enjoy the full bloom.
Removing spent flowers is also a great way to avoid surplus self-seeding and restricting the spread of tall coreopsis in your garden. The best time for trimming your plants is in late April. This will also help in maintaining the desired height of the plant.
Troubleshooting
The good news for gardeners is that this plant does not have any serious insect or disease problems. However, overwatering can be a problem as waterlogged soil can be harmful to the plant.
