| Length of adult plant leaf in centimeters. Typical size of the mature plant | 25-60 Large |
|---|---|
| Optimal number of rosettes for mature plant | 1-3 |
| Phase change. Quickness of transition to flowering phase | Crowding Needs constant thinning. Typically, these varieties bloom poorly |
| Salt-sensitivity | Salt-resistant Can tolerate adding 5% of organic fertilizer |
| The optimum and maximum pot size for two-year-old plant in centimeters | 18-25 |
| Intensity of transpiration | Standard type Standard type found in most hybrids |
| Leaf chlorophyll concentration | Standard foliage Standard foliage has rich green color, requires a lot of filtered light; 2-3 times greater than African Violets |
| Leaves thickness | Average |
| Stiffness of the leaves | Average Average |
| Ratio of length to width of the leaf. Leaves’ forms | Narrow The length of the leaf 5-8 times the width |
| Length of the flower stalk (peduncle) | Very long peduncles Distance between flowers and foliage more that 15 cm. These flower stalks could cascade if not supported |
