Yucca is a beautiful tall growing succulent with large rosettes of blade like, long and thin (and sharp!) leaves and massive, long lasting panicles of white and bell shaped flowers. In fact the blooms can last for months. And many of the species in this genus are very cold hardy.
For this reason, gardeners love yuccas: beautiful, generous, tough and, in many cases, even edible! But which yucca is best for you?
There are about 40 to 50 species of yuccas in the world, some are more tree like, others more shrub like.
The range goes from the large Joshua tree (up to 70 feet tall) to dwarf yucca (only 8 inches tall!) Thus, there is a range that goes from landscape planting to hedges, beds and even small spaces, like pots or small rock gardens. There are couple of varieties like Yucca guatemalensis and Yucca aloifolia which can be grown indoors as houseplants.
And to help you make the perfect choice, we have searched far and wide and found out the best yucca trees for different conditions, types of gardens and spaces.
Here are 18 popular yucca plant varieties for your landscape, along with our best tips for growing these drought-tolerant architectural plants in your garden or container.
Yucca Plant Overview
Yucca is a genus of 40 to 50 species of perennial plants, shrubs and trees native of the Americas and Caribbean islands. They are distinctive because of their sharp, sword like leaves (they actually can cut you) arranged in a rosette at the end of stems.
These stems often look woody, like trunks. But they are succulents, and succulents have no trunks as such, but stems. In fact, they are classed as shrubs, and not trees. Nevertheless, the stems often have a very upright habit, which makes them very decorative, as the ensemble looks a bit like the silhouette of a palm tree.
Where To Plant Yuccas In Garden: For this, they have a “sultry exotic look” as they are associated with dry places, like the Joshua Tree National Park in California. But they also have excellent architectural qualities. Yucca plants like arid growing conditions and they cannot stand swampy places.
Their natural areas are deserts or semi-deserts where it rains little, but also where the soil is sandy and very well drained. You will need to try to reproduce these conditions if you want healthy plants. On the other hand, the arid deserts and semi-deserts they come from also have very cold nights.
This means that yuccas are usually very hardy, they can withstand even sharp changes in temperatures and many species are actually cold hardy.
Some varieties will survive in USDA zone 5 (even 4!) and it’s not unusual to see them in the snow… I have even seen them – hold yourself – in full bloom under a coat of snow! For this reason, yuccas are different from many succulents, and gardeners love them very much.
Bloom time: They are very generous bloomers, with a huge number of long lasting flowers. Sometimes, they can bloom for virtually a whole year, including through the winter, depending on the species and conditions. The flowers are also often edible (they have a very sweet and delicate flavor, a bit like vanilla).
Soil: They are very tough plants, often very cold hardy and at the same time drought resistant and adaptable to most types of soil, as long as well drained, including infertile and poor ones. For this reason, they are very low maintenance.
And now you are about to find out what they have in common, how to grow them and how they all differ as well.

They are shorter than other yuccas, reaching a maximum of 22 inches in length (55 cm). They are of a dark green color and the effect of the rosette is “bushy”.

There are also cultivars of this yucca, notably ‘Golden Sword’ and ‘Garland Gold’. It is excellent for smaller gardens and spaces, including large containers. It is also very cold hardy.
6. Beaked Yucca (Yucca Rostrata)
Beaked yucca is a stunning, showy tree-like type of yucca. The rosette is made up of a multitude of thin, needle like leaves of a light blue to silver color.
These have an almost “fluffy” appearance, especially as they cone on top of a single trunk like stem, which coated in the whitish (yellowish) fibers of the old leaves.
It is, basically, “the Cousin It of yuccas”. However, don’t be deceived by the look; these leaves are so sharp they can easily pierce and cut.

It will also have filaments, like strings, that grow among the foliage, and this adds to its wild, rebellious look. The flowers will grow on tall panicles that look like feathers far above the foliage and they are white.

It is so decorative and sculptural that it won the Award of Garden Merit by the Royal Horticultural Society.The flowers of this variety of yucca are classical: they come in panicles that grow just above the foliage, they are bell shaped and their color is cream. This is a salt resistant plant too, so, it is ideal for gardens by the sea.
17. Thompson’s Yucca Plant (Yucca Thomsoniana)
Thompson’s yucca plant looks a bit like beaked yucca, but it is smaller. It has very spherical rosettes, with sharp, thing and light silver green or silver blue leaves. The effect is that of light and airy “fans” or palm trees.
In fact, they grow on thin stems and they too preserve the old dried up foliage, like palms, which end up looking like Hawaiian skirts under the rosettes.
The stalks with panicles will grow just from the middle of the rosettes and point straight upwards, giving rich inflorescences of may cream colored and cup shaped flowers.(Yucca thonpsoniana)
18. Joshua Tree (Yucca Brevifolia)
And we close with the giant of yuccas: the Joshua tree. Despite being the tallest of them all, it tales its Latin name (brevifolia) from its short leaves.
But this gives it its distinctive look, with a tall “trunk”, imposing branches still covered in the old dried foliage and… at the very end, small and compact rosettes of rapier shaped green leaves.
This look is very iconic of American deserts! The flowers come in panicle that can be 20 inches long (50 cm) at the end of the rosettes, and they are profuse and white.
However, they need a specific moth to pollinate them, called Tegeticula antithetica. It is bold statement in a garden, and one that will last, as this is a very long lived yucca: it can last for 150 years in fact!
