Coreopsis verticillata 'GRANDIFLORA'

Coreopsis - tickseed is a wonderful, maintenance-free perennial which shines its way through any garden with rich-coloured flowers all summer long. You can have a country garden or be a city garden enthusiast, coreopsis will still have features suitable for your plot. Thread leaf tickseed is probably the most sought after species in the market. It is tough, reliable, hardy, and apart from removing last year's stems it requires no care.

Grandiflora is a thread leaf tickseed variety, not to be mistaken for coreopsis grandiflora which is a different species. Its daisy-like flowers are bright golden-yellow with 8 accuminate petals, and appear for an extremely long flowering period from early summer (June) until the last warm days of autumn. Deadheading will enhance flowering and make the plant look nicer but is not necessary. It flowers abundantly every year without any help.

The fluffy, thread-like leaves are very decorative on their own yet before the flowers come out. And if you don’t mind me saying that they look like dill (without the scent). The desirable advantage of this variety is that it is not invasive, and does not seed itself around like some other coreopsis species, especially annuals. Grandiflora is very similar to a newer, shorter variety called Zagreb. Both the varieties are compact and bushy, but Grandiflora is taller and grows some 50 cm tall.

It will grow in nearly any soil, and as it withstands drought it is popular for rockeries. Grow it in full sun, possibly with a slight partial shade. No fertilizing required. Making it a glowing feature in your perennial garden bed is the reasonable and expected way of using it. But placing it among shrubs with different foliage and flowers will mean an honour for this easy and affordable beauty. Fully hardy to min. -34°C (USDA zone 4).
