The Yucca Gloriosa plant prefers alkaline soil with a pH of 5.5 to 6.5. This intriguing plant is hardy in USDA hardiness zones 6 – 10 and can withstand temperatures as low as 10° F (-12° C). Since the flower of this species is extremely fragile, it is best to grow Yucca Gloriosa as a houseplant.

Yucca Gloriosa tolerates pruning well and will respond with rapid growth when propagated from cuttings. The growth habit is more shrub-like than tree-like, but this plant makes a great specimen plant or upright hedge that can be kept trimmed and tidy. Pruning should be done during the dormant season to promote continual growth.

How Do You Care For Yucca Gloriosa?

Yucca Gloriosa is relatively easy to care for and requires little maintenance. Yucca gloriosa should be planted in full sun, which means at least six hours of direct sunshine every day. Some plants may flourish in partial sunshine, ranging from three to six hours of sunlight every day.

Once established, the shrub requires very little care. As a result, it does well in both well-drained sandy soil and rocky soil. The Yucca Gloriosa plant thrives in alkaline soil with a pH of 5.5 to 6.5. This intriguing plant is hardy in USDA hardiness zones 6 – 10 and can withstand temperatures as low as 10° F.

Yucca Gloriosa is drought resilient and may live in extremely dry conditions; nonetheless, it is preferable to water on a regular basis. When the soil dries out, provide thorough watering. Allowing Yucca plants to stand in water causes necrotic, black patches on the leaves. The following are the factors to consider when caring for Yucca Gloriosa:


Yucca Gloriosa thrives in full sun to partial shade. Plant or position your Yucca gloriosa in a full sun location that provides your shrub with at least six hours of bright, direct sunlight per day. Note that if you plant or position a Yucca gloriosa in a location that receives too little sun, it will not have access to the sunlight it needs to produce its characteristic white blossoms.


Yucca Gloriosa should be planted in well-drained soil. However, the soil ought to be mulched with a layer of acidic mulch like pine needles, pecan shells, or oak leaves to maintain an acidic soil pH of 5.5 to 6.5.

This plant is native to the sandy, coastal areas of the southern United States, from North Carolina to Florida. As a result, it does well in both well-drained sandy soil and rocky soil.


Yucca Gloriosa is a drought-tolerant plant. In the summer, water it once every three to four days. During the winter, water Yucca Gloriosa once a month. To avoid overwatering, water the drought-tolerant Yucca gloriosa sparingly.

When rainfall fails to deliver a comparable level of moisture, give the shrub only 1/2 inch of extra watering each week. You may need to increase the watering frequency if the plant becomes very dry. However, do not allow your plant to stand in water. Standing in water can cause black patches on leaves.


Fertilize your Yucca gloriosa in the early spring before new growth appears. Use a balanced, water-soluble all-purpose fertilizer or one designed specifically for evergreen plants. Follow the package directions for a single fertilizer application. Apply a balanced fertilizer at half-strength every time you water during the growing season.


Yucca Gloriosa can withstand a greater temperature range than many other popular indoor plants. The optimal temperature range is between 65 and 75 degrees Fahrenheit. They are, however, fully at home in 50 or 90 degrees Fahrenheit. The frost-sensitive Yucca gloriosa can be brought inside during the winter. In fact, this hardy plant is an excellent houseplant that will thrive whether grown indoors, in a greenhouse, or outside.


Yucca Gloriosa is a very hardy plant that can tolerate low humidity levels. Yucca Gloriosa types demand almost dry air (10% humidity or more). Irrigation should be done every two to three days in the summer and every 10 days in the winter.

As a result, Yucca Gloriosa is very adaptive to most indoor temperature variations and conditions. They want moderate humidity for growth, but as desert plants, they are completely happy in dry circumstances, and there is no need to shower this plant.


Yucca Gloriosa is propagated easily from stem cuttings and seeds during the spring and summer. When propagating Yucca Gloriosa, it is essential to keep the stems at the same level of moistness as the root.

If the stem dries out, it produces a lot of calli, which is thick and will eventually drop off naturally. On the other hand, new shoots will form if the stems are kept wet for several weeks before propagation.

Cuttings can be rooted in sand or soil mixture and potted in a standard soil mix or potted in a 3″ potting mix. Propagation by seeds can take 4-6 weeks to germinate.


Yucca Gloriosa is a relatively slow-growing species. Repotting should be done every two to three years during the spring. When repotting indoor Yucca Gloriosa plants, remove the yucca from the container with care, and use your fingers to dislodge any compressed roots.

Place the plant in the new pot and adjust the soil level, so it is seated at the same soil depth as in the previous container. Fill in around the roots with potting mix and lightly press it down to remove any air pockets.


Yucca Gloriosa needs to be pruned every year. Remove any discolored, diseased, or dead leaves as needed during the growing season to keep your Yucca gloriosa looking good and healthy. Sharpen and sterilize pruning shears to remove undesirable foliage from the bush.

Leave the removed leaf at the base of your shrub to avoid inviting or increasing undesirable insect activity.

Pests and Diseases:

Is Yucca Gloriosa Frost Hardy?

Yucca Gloriosa is hardy to zone 8. However, that plant may not survive a cold winter if it is not well-protected. Keeping your Yucca Gloriosa in a place with temperatures below 0 degrees Fahrenheit is ideal. That plant can tolerate temperatures as low as 20 degrees Fahrenheit, but below the freezing point will cause the stems to die.

The best way to keep your Yucca Gloriosa from freezing outdoors is to grow your houseplants in containers. It can be root bound and may need to be repotted every couple of years. If it has been wintering outdoors for several years, plant it in a container garden and provide good drainage for flowering and fruiting.

The frost-hardy Yucca Gloriosa can also be trained up a trellis. Container-grown plants may need to be pinched back occasionally to stimulate new growth, and you will want to protect them from severe frost by covering the plant with hardware cloth.

However, Yucca Gloriosa is known to survive as far north as zone 6 if they have been previously cultivated and kept over winter. They have survived temperatures to -20 °F (-28 °C).

Yucca gloriosa plants are very easy to care for. They don’t require frequent watering and can easily survive with only once a month watering during the winter months.

Yucca gloriosa is native to the southern coast of North America and thrives best in USDA plant hardiness zones 7 through 11. Yucca gloriosa is prized for its minimal moisture requirements and thrives in warm, dry regions with little maintenance.

When growing Yucca gloriosa indoors, keeping the soil evenly moist is important. A good watering schedule is once a week during the winter or twice a month during the summer.

Yucca gloriosa needs moderate to little water when grown indoors. Yucca Gloriosa plants need to be kept evenly moist with water that drains through the drainage holes at the bottom of the potting pot. The sunlight and temperatures in your home may dictate the amount of water your yucca gloriosa needs.
