Red Yucca - Hesperaloe parviflora: Generalities
Succulent, evergreen shrub, native to central-southern America. Stemless, it has long cylindrical, arched leaves, which give rise to large rounded bushes, which reach 90-100 cm in height. The leaves of the esperaloe are thin, fleshy and pointed, of green-gray color; on the edge of the leaves there are characteristic "curls" constituted by a material with a paper consistency. From the spring to the cold autumns from the center of the bush develops an erect stem, even 150-180 cm tall, stiff, on which numerous bell-shaped flowers bloom, of red or rosé color. This succulent can be grown in pots, but it is also suitable as an exotic specimen in Mediterranean-style gardens, or even as a low hedge.
Exposure: the hesperaloe prefer sunny, or even partially shady, positions; they can withstand temperatures of very low degrees below zero, but in winter they need to be positioned in very sunny places, possibly sheltered from the cold wind.
Watering: from March to October water only in case of very prolonged dry periods; during the cold months avoid watering. These succulents can easily withstand drought, and are generally satisfied with the rains. In spring sprinkle around the plant a small dose of slow release granular fertilizer, specific for flowering plants or succulents.
Soil: they are grown in not too fertile, sandy or even stony, very well drained soil; these shrubs are very suitable for creating low maintenance gardens.
Multiplication: takes place by seed, in spring, in a seedbed protected from the cold.
Pests and diseases: in general they are not affected by pests or diseases; occasionally the cochineal can nestle under the foliage. Excessive watering or a very humid climate can favor the development of radical rot.
