Yuccas for landscaping
Yuccas for landscaping (Agavaceae). Here are a few drought-tolerant Yucca plants that can be used just about anywhere the sun shines. Depending on the variety they can grow from east Texas, Denver and all the way to southern California. Their blooms are a spectacular pale white color and often will have several spikes shooting out at the same time.
They are slow-growing however, additional summer watering will help speed up the process. Yucca faxoniana is hardy to about 10° f. It’s also called a Spanish Dagger.
The torreyi yucca is hardy to about 0° f. Yucca aloifolia has very stiff leaves and is a bit faster growing than the above mentioned. This one does well in containers with fast draining soil. A little shade will help darken the color of the leaves if it gets too much sun.
Yucca’s are drought tolerant. Many landscapers will install a drip system for these type of plants. But you should remove the drip system after 3 years of growth.
They are quite often overwatered. However, if you have your Yucca plant in a container they will require more watering as opposed to normal ground planting – Mainly during the hot summer months.
Yucca’s Require little water
Very little water if any during the winter months. They thrive in sandy soils and lots of full hot sun. You would apply insecticides the same as other non-drought tolerant plants.
Most are very low maintenance. Prune or remove dead or dying leaves to encourage new growth. They are durable easy to grow plants but they can get diseases and insects will eat the fronds. Grubs are also a problem in a landscape environment. Grubs will eat the root system of Yucca’s.
Types of Yucca’s
Yucca rigida. Also called the Blue Yucca because of its blue very sharp fronds. It will grow up to 12 ft. in height. Like most Yuccas, it will shoot out nice white plumes typically around mid to late spring.
The soaptree Yucca flower is New Mexico’s State Flower. There are many species of the Yucca plant but the flower will bloom on most of these species. Yucca Elata (Soaptree Yucca photo below) – This one is the most common yucca around the southwest. Very slow-growing thin leaves with creamy white-colored flowers during the spring months. When the flower seeds dry up the wind will blow them into the soil and with a little rain, they will germinate.

A brighter red tip Yucca. This is a smaller version of the red tip yucca. It does not set seed pods so there is less maintenance and it is an evergreen in the Southwest. Can be used in a container and perfect for Xeriscape or rock gardens.
Adams Needle – Yucca filamentosa. A perfect Yucca for a container. Slow growing Yucca with sharp-edged dark green fronds. Beautiful fragrant snow-white blooms during late spring or early summer. It will retain its color and fronds during the cold months. Easy maintenance and care.
Yucca recurvifolia – Also called soft leaf Yucca. Great blue-green fronds that create an interesting year-round color. Tall flower spike white blooms. An excellent accent plant that really grabs attention! A great choice for containers or as a specimen. Another great evergreen yucca that does well in and around a patio, porch or front entrance.
The Variegated Spanish Dagger (Yucca gloriosa ‘Variegata’): Perfect in a decorative formal pot. Easy care very low water. Make sure your container drains well.
Yucca treculeana – Spanish Dagger. It resembles a type of palm but it is a true Yucca. It can grow up to 20 ft. in height. The long dark green bayonet-type fronds will grow about 3 ft. long. You can remove the bottom bark for a smoother trunk design.
The Banana Leaf Yucca (Yucca Baccata) and the Variegated Agave (Americana Agave Variegated).
Both require very little water. Plant them in a desert landscape with rocks and other low water type plants. Yucca’s are somewhat susceptible to mealybugs. Look for white cotton-like appearance along the inner sides of the fronds. Spray with neem oil to kill them.
