The curassavica asclepias is an evergreen shrub native to Central and South America, widespread for some time as a wild plant in most of the tropical and subtropical areas of the globe; reaches 50-80 cm in height. It has an erect habit, not very branched, the stems are green, semi-woody at the base; the foliage is dark green, oval, 10-15 cm long; the leaves and stems contain a milky, poisonous sap, which can cause skin irritation. From late spring to the autumn cold, it produces numerous small flowers, gathered in roundish or umbrella-like racemes, of an orange red color, very showy, with a particular shape. In autumn the flowers are followed by fruits, small pods that contain some fertile seeds. Plant of easy cultivation, it is used as a background in the borders; it is also grown as an annual. To keep the shrub compact and favor a prolonged flowering it is advisable to remove the withered flowers and occasionally trim the erect branches.
The Asclepias curassavica is planted in a sunny, or partially shady place, needing a place where they can receive a few hours of direct light a day; they do not fear the cold, even if they can be ruined by intense or very long frosts; plants damaged by frost often produce new shoots during the following spring season. They are often grown as annuals, above all because they release many fertile seeds, so new plants are developed every year in the same area of the garden; these asclepias they flower quickly, a few weeks after sowing.
The asclepias curassavica can withstand short periods of drought, but to have healthy plants and abundant blooms it is necessary to water regularly, keeping the soil slightly damp, or intervening every time it dries.
In winter, on the other hand, it is necessary to thin out much watering, especially for plants that are grown in the ground.
From March to October, add the fertilizer for flowering plants to the water, every 15-20grioni.
Generally these plants adapt to any soil, as long as they are well drained; it is advisable to avoid too compact and poor soils. It is possible to cultivate curassavica asclepias in pots, in which case it is necessary to repot the plant every 2-3 years, to renew the soil and allow the correct development of the roots. Check that water does not build up, which can be dangerous for the health of the plant.
The multiplication of this genus of plants occurs preferably by seed, given the ease with which the seeds germinate and the rapid development of the plant; in late spring it is also possible to take apical cuttings, to be rooted in a mixture of peat and sand in equal parts.
