Browallia

The genus Browallia includes b species of herbaceous annuals and perennials, but used as annuals or shrubs. Plants are decorative thanks to the tubular flowers that bloom throughout the summer until early autumn. The flowers are colored in various shades of blue, purple, sometimes white. Leaves are ovoid or lanceolate. American Brovallia (Browallia americana) is a species up to 60 cm high, with blue or purple large single flowers. Large-flowered brovallia (V. grandiflora) is characterized by large white or blue flowers. Brovallia beautiful (B. speciosa) - a species 60 cm high, with lanceolate green leaves and single violet-blue (less often pure white or purple with a white throat) flowers, larger than in other species. Brovallia sticky (B. viscosa) does not grow above 30 cm; ovoid leaves, numerous blue flowers with a white throat, white, purple.

Cultivation

Plants of the Brovallia genus are grown outdoors in flower beds, in curbs, for cutting or in pots on balconies, terraces and in rooms. When grown outdoors, seeds are sown in the spring when the danger of frost is over. For early flowering, seeds can be sown early in a greenhouse, and planted in a flower bed in early June. If the seeds are sown in pots in late summer, the plants will bloom at home in winter. Brovallia is undemanding to the soil, responds well to feeding during the growing season. In spring and summer, once every 30-40 days, a complex mineral fertilizer is added to the water for irrigation in an amount of 10 g per bucket. Tall specimens require a garter. If the plants are too stretched or grow erratically, they are pinched.

Location

Brovallia is photophilous, it is placed in a sunny place in the garden or it is chosen with maximum illumination when growing in pots.

Temperature

Plants of the Brovallia genus are resistant to high air temperatures.

Watering

Water regularly, in moderation, avoiding stagnation of water in the soil.

Care

Remove faded or damaged parts of the plant.

Reproduction

Brovallia is propagated by seeds, which are sown in early spring in boxes filled with seed soil, maintaining the temperature at 18 °C. The grown seedlings are transplanted into pots one by one. Placed in open ground at the end of May.

Diseases

Entyloma browalliae causes rotting and wilting of plants. It is difficult to get rid of it even with the help of chemicals, so it is very important to take care that the soil in the garden or the substrate in the pot is sufficiently loose and well-drained. Aphids and chlorosis provoke yellowing and weakening of plants. It is easy to get rid of aphids by treatment with preparations against this insect; chlorosis treatment requires feeding with iron chelates.

Acquisition

Plants of the Brovallia genus are easy to find in nurseries and horticultural centers. Make sure they are free of chlorine stains.
