'Cardinal Star'

Flowers are like small petunias and colour is warm red with yellow star centres in each flower.
Proper watering is the key to growing Superbells. Never allow the roots to get too wet, so water them only when the top of the potting mix/soil is dry. As they bloom so profusely they will benefit from regular applications of a well-balanced fertiliser throughout the flowering period. A regular addition of seaweed extract is beneficial. They are best grown in full sun. Occasionally pinch back the trailing stems to reinvigorate growth.
