Tickseed
Coreopsis grand flora is a native of the southern United States and was introduced into European
gardens in 1826. It flowers here in southeastern Indiana in late May to mid June. There are many
different varieties of this perennial flower, and similarities between C. grand flora and C
lanceolata have led to confusion in both seed and nursery catalogs and perennial books.
Hardy to USDA Zone 4, Coreopsis grandflora is one of the more desirable flowers to have in the
perennial garden. The name "coreopsis" has origins in Greek, and means "resembles a bug". This term
refers to the seed which resembles a small tick, which is also the common name, Tickseed.
Coreopsis grand flora is a fairly short lived perennial flower, surviving around two years or so.
It will self seed, so it can perpetuate itself in your garden in that fashion. It will grow around
ten to twelve inches tall and flowers profusely for about four weeks. If you dead head the plants, it
is possible to get another small flush of bloom, but you will sacrifice the seeds which may give you
more plants.
This Tickseed, like all coreopsis, will tolerate poor soils and likes full sun the best. The bright
yellow flowers with dark markings will brighten any perennial garden and will provide lots of color
with little effort after the plant is established. Coreopsis grandilflora is a good choice for your
perennial garden.
