Diascia cordata


dozens of annual or perennial herbaceous plants, all native to southern Africa, belong to the diascia genus. D. barberae is a small perennial plant, falling or semi-climbing, with thin green stems, arched or prostrate, generally these plants are kept at a height of less than 30 centimeters, the leaves are thin and delicate, almost needle-like, sometimes oval , light green in color; from late spring to the first 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 cold, flowering stops, and as temperatures go down, the plant goes into vegetative rest, drying up the aerial part.


To get the best result and enjoy a copious flowering it is good to put it in a sunny place, or in the partial shade, so that the plants can enjoy a high brightness, which promotes the production of flowers. Exposure in the shade, in fact, does not allow a great 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 place the containers in a sheltered place until the following spring, so as to repair them from cold climates, which would cause their death.


To obtain the best possible growth, it is good to water the specimens belonging to this variety regularly, but allowing the soil to dry between one watering and another; in July-August it is good to water often, wetting deeply the soil. Avoid the formation of water stagnations that can cause radical radicals dangerous for this kind of plant.
For a luxuriant and abundant flowering it is advisable to provide fertilizer for flowering plants, every 10-15 days, mixed with the water of the waterings.


The Diascia cordata are placed in rich, loose and well-drained soil, which does not allow the formation of stagnant water which is dangerous for the growth of these plants. You can use universal soil mixed with a little sand or pumice stone with medium granulometry; these plants can be planted in the ground, but they grow very well even in pots; with this solution it is possible to enjoy the slightly falling flowering better if the pots are placed in hanging containers.


The multiplication of diascia cordata specimens occurs by seed, at the beginning of spring in a seedbed held or 18-20 ° C, or directly at home in April-May, when the external temperatures are milder and there is no risk of frost late that would compromise the growth of these plants; in May it is also possible to practice cuttings that can be placed in full ground, in bright but sheltered areas, to allow the new shoots to take root.
