With global warming, dry gardens or at least very water-efficient ones have become trendy. If you are one of those gardeners concerned with conserving water resources, you can follow the xeriscaping trend by adopting a red yucca or Hesperaloe parviflora. I invite you to discover this xerophytic plant in 5 questions.
1- Why is Hesperaloe parviflora called false yucca?
Hesperaloe parviflora is a perennial succulent plant in the Agavaceae family.
Despite its nickname red yucca, this rosette-leaf succulent is not a yucca. That is why it is also sometimes called false yucca.
This plant, which can reach 1.2 meters in height and spread under good growing conditions, is native to the arid regions of the Chihuahuan Desert.
2- Why plant a red yucca in your garden?
With global warming and repeated heatwaves in summer, the species Hesperaloe parviflora is promised a bright future. This agave native to arid regions resists heat and drought very well.
In addition to being very water-efficient, it is very easy to grow and highly aesthetic. Its graphic silhouette is particularly effective in contemporary gardens and rockeries, especially since it produces light inflorescences in summer that can reach up to 1.5 meters in height.
With its bright red flowers, the red yucca certainly lives up to its name! It is also sometimes referred to by the vernacular name coral yucca. Its flamboyant and airy blooming is one of its greatest assets. Additionally, it has the advantage of attracting certain pollinating insects.
3- Where to plant a red yucca?
Despite its desert origins, Hesperaloe parviflora is not overly sensitive to cold. It tolerates temperatures down to -15°C, provided it is placed in a sheltered location with perfectly drained soil.
The red yucca was traditionally used in Mediterranean climate zones. However, its cultivation can now be considered in other regions of France, especially since it adapts well to a bit of humidity.
In your garden, it can find its place in a rockery, on a slope, or in a dry bed without any watering, preferably in full sun.
Caution: choose a location away from your house and plumbing. Like many desert plants, Hesperaloe parviflora has a very deep taproot, and its lateral roots can reach lengths of six to nine meters in nature!
4- How to plant red yucca?
If you live in a cold climate region, schedule the planting of the red yucca in spring. Everywhere else, it is best to plant this succulent in autumn.
Choose a well-sunny location and provide it with very well-drained soil, sandy and rocky. Avoid wet lands and too heavy soils.
If your soil is heavy, add river sand to the planting hole and plant Hesperaloe parviflora on a slope or mound.
The first year, to promote the plant's growth, you can water it once a week in summer. After that, it can do without watering completely.
5- What care is needed for the red yucca?
As we mentioned earlier, the red yucca is a very easy plant to grow. This species from the Agavaceae family is ideal for beginner gardeners who tend to forget watering!
Not only does it not need watering, but it also doesn't require fertilizer or pruning. Maintenance is limited to cutting off faded inflorescences and damaged leaves.
You don't need to worry about it because it is not very susceptible to pests and diseases. In summary, it's a trouble-free plant with surprisingly easy cultivation.
Note: you can easily propagate this plant by taking offshoots with their roots from its base. Simply replant them immediately, in spring or fall, depending on your region's climate.
