Details



Coreopsis grandiflora ‘Sunray’ is a newcomer to the numerous coreopsis offerings, with double flowers this shorter variety grows to around 45 to 50cm (18 to 20in) in height. They are very easily grown, are pest resistant and will flower the first year from an early sowing.

When it comes to all out colour Coreopsis is hard to beat. This clump forming, very showy, sun loving perennial with deep yellow daisy like flower heads and mid green leaves begin flowering in late spring and continue through most of the summer. They can hold their own in front of the showiest kniphofias, crocosmias, cannas and dahlias.
For almost any sort of garden, a hardier, more beautiful flower would be difficult to find. They are drought tolerant plants, which will adapt to poor soil, have great durability and perform best in full sun or light shade. ‘Sunray’ can be grown in the garden but is also useful for a large container. They make a beautiful and enduring cut flower and cutting the blossoms will encourage the plant to bloom even more

Butterflies adore coreopsis (next to purple flowers, butterflies like intensely yellow blooms best), so gardeners wanting to attract butterflies would do well to include coreopsis in their plans.
Deadhead the plants to provide a continual show, at the end of the flowering season, allow seeds to remain for the birds to enjoy.



Sowing: Sow in late winter/late spring or late summer/autumn.
Sow at temperatures of around 16 to 21°C (60 to 70°F)
Fill pots or containers with a well draining seed compost, stand the containers in water to moisten thoroughly, then drain.Sow the seed on the surface or the soil, and press them lightly into the soil. Do not cover them, as they need light to germinate. Keep moist. Seed will germinate in 20 to 25 days
When seedlings have their first pair of true leaves and are large enough to handle, transplant into 7.5cm (3in) pots.
For autumn sown seedlings, pot on again and grow on in a cool greenhouse or sheltered part of the garden. Plant outside into their permanent positions in the spring after all risk of frost has passed. Plant 38cm (15in) apart in a sunny spot on light well drained soil.


Cultivation:
Coreopsis do not require a highly fertile soil, and feeding them too much makes them tall and floppy. A half-handful of general purpose slow acting granular fertiliser scattered on the soil or worked into the soil around each plant in the spring is plenty for the season.
Trim spent flowers off regularly to promote continuous production of new flowers. If not deadheaded, only naked flower stalks will remain above the foliage. Cut plants back severely after flowering and the new growth will be strong and healthy. Cut back nearly to the ground in the winter. Coreopsis are pest resistant. Leaf spots may be a problem especially in wet years, but they usually don't affect the first bloom.


Plant Uses:
Cottage/Informal Garden, Flower Arranging, Flowers Borders and Beds, Gravel Garden
Low Maintenance or Wildlife Gardens


Natural Dyes:
The blossoms of the Coreopsis can be used to make yellow and orange dye.
It yields a bright permanent orange when used with alum.


Nomenclature:
The name coreopsis is derived from Greek opsis meaning 'resemble' and koris, meaning 'bedbug.'
Its seeds, possessing two horns, might be said to remind one of a bedbug. It is not surprising, then, that a common name for the coreopsis is tickseed, due to some people's opinion that the seeds look like ticks.
