These plants can reaches a height of 80 cm. The leaves are up to 15 cm long, glaucous, greyish green to blue-green, and thin.
The red, delightfully scented blooms are produced single or up to five at a time in a cyme. The original natural flower colour is a vivid pinkish-purple, although cultivars of other colours, such as red, white, yellow, and green, have been developed.
These sturdy plants have large, full flowers that release an overly sweet spicy scent. Start by giving the seeds a proper indoor start. Six to eight weeks before the last day of frost in your location, sow the seeds.
Problems with insects and diseases are rare. Use pesticides, repellents, or fungicides as soon as an insect or disease problem arises. In order to offer the appropriate level of support, you must determine in advance how tall each variety will grow. To ensure that the stems remain upright, the support should be put in place as soon as the plants are planted or when they first appear from the ground in the spring.
