some dozens of annual or perennial herbaceous plants belong to the genus diascia, all originating in southern Africa. The D. barberae is a small perennial plant, hanging or semi-climbing, with thin green stems, arched or prostrate, in general these plants remain less than 30 centimeters high, the leaves are thin and delicate, almost needle-like, sometimes oval , light green in color; from late spring to the early cold it produces small apical spikes of red, yellow, pink, white or orange flowers. The Diascia cordata bloom profusely until autumn, to make the flowering more abundant it is advisable to remove the withered flowers. With the arrival of the cold the flowering stops, and with the fall of temperatures the plant goes into vegetative rest, drying the aerial part.
To get the best result and enjoy a copious flowering it is good to plant in a sunny place, or in partial shade, so that the plants can enjoy a high brightness, which promotes the production of flowers. A shadow exposure, in fact, does not allow a large flowering and the production will be very poor.
Often they are grown as annuals, but if desired it is possible to grow them in pots and store the containers in a sheltered place until the following spring, in order to shelter them from cold climates, which would cause their death.
