Characteristics of the white Lisianthus
The white Lisianthus, belonging to the botanical family of the Gentianaceae and to the genus Eustoma, is an annual semi-rustic herbaceous plant, if grown outside for the trade of cut flowers, and perennial if kept in pots in the apartment, for ornamental purposes. Lisianthus is highly appreciated for its elegant and simple appearance and is widely used for decorations for weddings, first communions and other celebrations. The plant originates from America, in particular from the southern United States and Mexico, therefore countries with a warm climate. It has a slow growth and its stems are generally about 50 cm long, thin and flexible, covered by lanceolate and waxy greenish-blue leaves. The white flowers are large and bloom at the tips of the stems. Lisianthus blooms between spring and summer.
Positioning, climate and reproduction
Lisianthus loves moderate climate, needs a lot of light and fears intense cold and rain. It is necessary, however, to avoid direct sunlight, to prefer partial shade, not to keep the plant near and sources of heat and not to subject it to drafts. The ideal growth temperature is between 18 and 22 degrees and never lower than 17. The multiplication of the white Lisianthus occurs by seed or by division of the tufts. The sowing will be carried out in boxes in winter, towards the end of February, leaving the soil in a sheltered place, at a mild temperature, until the seeds germinate completely. This type of reproduction ensures the best success, leading to a lush flowering in the summer. The division of the tufts should instead be carried out in spring by replanting the parts of the plant.
