Yucca recurvifolia, called curved-leaved yucca or weeping yucca is a shrub plant belonging to the family Agavaceae. Yuccas are one of the few plants that can be described as a tree among monocots.
Yucca recurvifolia is native to the southeastern coasts of the United States, often found in sandy dunes or in seaside scrub. It is botanically considered to be a variety from Yucca gloriosa, sharing his robustness and hardiness, but with a more flexible form, a beautiful silhouette softened by its drooping leaves.
The weeping yucca is a remarkable landscape plant in the look xérophyte and exotic: where winters are too harsh, it is an interesting alternative to variegated agaves.
Description of curved leaf yucca
Yucca recurvifolia presents an apical rosette of leaves carried by a trunk, a plant which becomes 2 to 3 m tall with age, and which branches somewhat. In the long run, when his rod rises and is stripped he takes it the look of a small palm tree.
Its leaves are sword-shaped, 60 to 90 cm long and 5 to 7 cm wide. They have the characteristic of being flexible and hanging. They have a smooth margin and end with a sharp point. The natural shape is a pretty bluish green hue, all the more striking as this blade flattens out to fall. Its lighter variegated shapes are also well highlighted by the shape of the sheet.
Flowering comes from the center of the rosette of leaves, when this is sufficiently developed and closes the growth of the apical bud in favor of lateral ramifications or stump shoots. Yucca recurvifolia ends up forming a small colony over time.
The inflorescences are imposing : a conical spike that rises 60 to 150 cm above the foliage. It bears pendulous flowers with 6 waxy tepals of cream color. They bloom in late spring and early summer.
In its native region, the curved-leaved yucca is pollinated by a specific insect, non-existent in Europe. It therefore does not produce fruits or seeds in France, unless you make a pollination manual and cross.
