Tips for Growing Carnations

Some carnations are perennial, others are annual, there are tall species, there are low and even dwarf, but they all develop from a woody strain with fine foliage, between green and gray. It is not complicated to get this plant from seeds, although you can also buy already established bushes and create spectacular flower beds very quickly.

The carnation flower is cup-shaped and its petals, wavy or curly, can be of all colors except blue.
