It is a herbaceous perennial plant growing to 80 cm tall. The leaves are glaucous greyish green to
blue-green, slender, up to 15 cm long. The flowers are produced singly or up to five together in a cyme;
they are 3–5 cm diameter, and sweetly scented; the original natural flower colour is bright pinkish-
purple, but cultivars of other colours, including red, white, yellow and green, have been developed.
Carnations require well-drained, neutral to slightly alkaline soil, and full sun. Numerous cultivars
have been selected for garden planting. Typical examples include 'Gina Porto', 'Helen', 'Laced Romeo',
and 'Red Rocket'. Colombia is the largest carnation producer in the world.
For the most part, carnations express love, fascination, and distinction, though there are many

Light red carnations represent admiration, while dark red denote deep love and affection.
White carnations represent pure love and good luck, while striped (variegated) carnations

Pink carnations have the most symbolic and historical significance. According to a Christian
legend, carnations first appeared on Earth as Jesus carried the Cross. The Virgin Mary shed tears
at Jesus' plight, and carnations sprang up from where her tears fell. Thus the pink carnation
became the symbol of a mother's undying love.
