Abstract
A carnation plant known by the cultivar name Crestone was developed through a breeding program and is particularly characterized as to uniqueness by its dwarf growth habit and the following combined characteristics: upon pinching a rooted cutting, forms 3 to 5 lateral stems 18 to 25 cm long, each developing a terminal flower and 4 to 6 lateral buds which open intermittently after the terminal flowers seneses; white flowers 4.5 to 5.5 cm in diameter have a purple picotee edge, but without fragrance; can be grown under specified environmental conditions either as a single pinched plant per 10 cm pot or 3 pinched plants per 13 cm pot, which results in an ideal new flowering house plant.
