Characteristics of Pentas lanceolata
La pentas lanceolata It is a perennial plant with a rounded and compact shape, native to warm regions of Africa and the Middle East. It can reach up to 1 meters tall and its maximum width is usually around the same size, depending on space and care. Its stems are erect and woody, branched, and support a dense foliage formed by large, elliptical or lanceolate leaves, deep green in color with very pronounced veins. These leaves and young stems have a slight pubescence that gives them a unique texture.
Their flowering is undoubtedly the most attractive feature. Pentas produce clusters or corymbs of small flowers shaped like a five-petaled star. The most common colors are red, magenta, pink, mauve, white, and lilac. In warm climates, flowering lasts almost year-round, while in temperate climates, it is enjoyed mainly from spring to early winter.
Location and light exposure

In the colder months or when grown indoors, it's ideal to place it near south- or west-facing windows where natural light is most abundant. Although it tolerates partial shade, its flower production will be significantly lower.
Type of soil and suitable substrate
The ideal soil for Pentas lanceolata is rich in organic matter and with excellent drainage. It can be planted in both gardens and deep pots. A mixture of universal soil with worm castings and some sand or perlite is recommended to improve aeration and prevent waterlogging.
It prefers a slightly acidic substrate, with a pH around 6,5, although it adapts well to most soils as long as excess lime and compaction are avoided. It's important to have a well-drained base of the pot to prevent water from accumulating and causing root rot.
Irrigation: frequency and recommendations
Watering the Pentas lanceolata should be abundant during the growing and flowering season, especially in summer. It is preferable to apply regular watering but without waterloggingThe best time to water again is when the top layer of the substrate has dried. In humid climates or in autumn and winter, it's advisable to space out waterings, as the plant enters dormancy and needs less water.
In summer, frequent, short waterings may be necessary to avoid water stress, but always ensure that the substrate dries slightly between waterings. Avoid leaving water in the pot's saucer to prevent the development of fungus and root diseases.

Pruning, pinching and maintenance
Pruning is essential to stimulate branching and maintain a compact and vigorous plant. At the end of winter, perform a light prune to remove dead branches and control its shape. Remove faded flowers throughout the year to encourage new blooms. If you want a denser, more balanced plant, you can pinch off the apical buds from time to time.
