About The Desert Lily (Hesperocallis)
As a part of the Hesperocallis, the Desert Lily is not part of the main “true lily” family. It was once classified as a member of the Liliaceae family, but that has been changed.
Hesperocallis undulata is the only member of the genus and the only flower that deserves the name Desert Lily. However, many other lily-like flowers share this common name, so it’s best to use the scientific name to avoid confusion when shopping for new plants for the garden.
Desert Lily plants are native to the deserts of the Southwest of North America. They are also commonly called Ajo Lilies.
The plants can grow up to 2 feet tall but tend to remain shorter. The leaves are sword-shaped with a wavy edge, usually displaying quite a pale gray to silver color in the native habitat.
Multiple lily flowers appear on a flower spike, a creamy white color inside and a dark silver on the outside. They’re very striking and easy to spot from a distance, making a significant impact on the landscape.
The plants aren’t huge, but they tend to form dense patches that can be three or four feet wide after a few years of growth.
The Meaning & Symbolism of Desert Lily
The Desert Lily is known by that name for its preferred habitat. It’s not found outside of the desert and won’t thrive in more humid or forested environments. Its other common name, the Ajo Lily, is based on the Spanish word for garlic.
The people native to the Southwest of North America used to dig up the bulbs and use them for seasoning food because it has a savory flavor similar to garlic.
The Latin name Hesperocallis comes from the name Hesperos, which means from the West, and kallos, which means beauty. It’s a literal name as well since the plant is only found in the Western part of the US and has a lovely appearance.
As a beautiful and almost exotic-looking flower, the Desert Lily symbolizes standing out from the crowd and thriving even in a different environment. It was once believed to be just another Daylily, but it’s now understood to be its own unique type of Lily.
Try giving it as a gift or including it in a flower arrangement for someone you want to encourage to stand out and tell them that you appreciate their unusual beauty or skill.
Uses and Benefits of Desert Lily
The tubers of this plant were once eaten as a seasoning and a survival food because they taste somewhat similar to garlic. However, it’s not known if the plants are safe to consume on a short-term or long-term basis, so it’s best not to experiment with them on your own. Many moths and butterflies visit the large flowers for nectar.
How to Grow Desert Lilies
It’s not easy to grow the Hesperocallis Lily, especially if you’re outside the plant’s native range. When planted in the winter, the seeds only break dormancy and need cold but wet conditions to trigger their growth.
Growing the Lilies from roots or tubers is slightly more straightforward, but you’ll still need to plant them in early spring or late fall to get them established before hot summer temperatures arrive. The plants can only grow in USDA Zones 8 through 11.
They don’t do well in containers or pots, but they can handle growing in planters with sufficient drainage. Look for sandy and very dry areas with a slight slope that can shelter them from wind that could dry them out or knock the blooms off.
Here are my essentials tips to successfully grow Desert Lilies in your garden:
Where to Plant:
Choose a planting location that provides full sun or partial shade. Desert Lilies prefer well-draining soil and can tolerate sandy or gravelly soils commonly found in arid regions. Ensure the planting area has good air circulation to prevent excess moisture buildup around the bulbs.
Best Soil:
Desert Lilies thrive in well-draining soil. Sandy or gravelly soil types are ideal for their growth. Amend heavy or clay soils with organic matter or sand to improve drainage.
Sunlight Requirements:
Desert Lilies require plenty of sunlight to grow and bloom successfully. Provide them at least 6 to 8 hours of direct sunlight daily. They can tolerate some shade, particularly in hotter regions, but full sun exposure is preferred.
Watering Frequency:
Desert Lilies are drought-tolerant plants that have adapted to arid environments. They prefer infrequent, deep watering rather than frequent shallow watering. Allow the soil to dry out between waterings, and water deeply when you do water to encourage deep root growth.
Fertilizing Needs:
Desert Lilies generally don’t have high fertilizer requirements. However, you can apply a balanced slow-release fertilizer or a light application of a phosphorus-rich fertilizer in early spring before new growth emerges. Follow the instructions on the fertilizer packaging for proper application rates.
Pruning:
After the blooming season, you can remove the spent flower stalks by cutting them back to the base. This helps maintain the plant’s appearance and directs its energy toward bulb development. Avoid removing foliage unless it is brown or completely dry.
Overwinter Care:
Desert Lilies are generally hardy in regions with mild winters and can be left in the ground. Mulching around the plants can provide some protection from frost. In colder areas, where freezing temperatures are typical, you can lift and store the bulbs in a cool, dry location until the following spring.
Caring for Desert Lily
Desert Lily plants rarely deal with any diseases or suffer from pests. Instead, they’re more likely to become injured from harsh winds if planted in an exposed spot. Full sun and heavy rains won’t hurt them, although a sudden rainfall may knock open flowers off.
You can prune or deadhead the plant for a cleaner look. It’s unlikely to trigger any further flowering, but it will help keep the plant under control if you don’t want it to spread many seeds.

Desert Lily FAQs:
How long do Desert Lily flowers bloom?
The Desert Lily blooms all summer and into the fall until cold temperatures end the appearance of new buds and blossoms. Depending on the warmth of the area, it may begin flowering again very early in the spring compared to other desert plants.
What is the ideal climate for growing Desert Lilies?
As the name suggests, these plants like warm desert climates. They can handle colder nighttime and winter temperatures as long as it’s not too dry. Summers can be incredibly dry and harsh without interrupting the flowering or growth of this plant as long as it’s well-established first.
Can Desert Lilies grow in containers or indoors?
They can’t grow indoors and won’t respond well to most containers. Desert lilies need dry soil and plenty of space to grow, so they’re best planted in the ground. Avoid planting them in planters with no drainage or even slow drainage since it will rot their roots over the winter.
How often should I water my Desert Lilies?
Only water new Desert Lily plants you’re trying to get established. Once they are growing steadily, avoid giving any further water. These plants are adapted to the desert and won’t respond well to watering.
When is the best time of year to plant Desert Lilies?
Desert Lily seeds must be planted over the winter to give them a chance to germinate. The roots and tubers can be planted in the fall or spring instead, but they need extra care during the summer for the first year if you choose to do that.
How can I protect my Desert Lilies from pests and diseases?
Desert Lily plants aren’t susceptible to most pests or diseases. Simply avoid fertilizing or watering the plants, which can weaken the roots and leave them open to rot or other issues. These plants only need what’s available in the dry, sandy soil of the desert and won’t respond well to anything richer. Many people have killed off their Desert Lily plants by trying to help them with mulch, fertilizer, or other unwanted additions to the soil.
How can I extend the lifespan of my Desert Lilies after they’ve been cut?
Desert Lily blooms tend to last two weeks or longer as long as you change the water daily in the vase. Don’t let them sit in full sun after cutting, and keep the flowers cool until you plan to display them.
