Donkey's tail (Sedum morganianum) is a popular succulent with rows of fleshy, tear-drop-shaped leaves that are blue-green. Native to Honduras and Mexico, mature specimens of the donkey tail plant grow slowly and steadily but can reach trailing lengths of up to 4 feet long in six years time (though the average length is closer to 24 inches). They are most commonly grown as potted plants, often suspended as hanging specimens. Indoors, the succulent can be planted and very easily propagated year-round by stem cuttings or laying a dropped leaf on top of soil, while outdoors it does best planted in early spring. Red or pink flowers can emerge in late summer, though the plant rarely blooms indoors. The donkey tail plant is safe and considered not toxic to people or pets.

Donkey's Tail Care

All things considered, donkey's tail succulents grow easily if you follow a few simple rules. Like most succulents, they do well if left slightly neglected—if you forget to water them once or twice, they'll still be just fine. In fact, overwatering is the worst thing you can do to a donkey's tail. Where you really have to treat your donkey's tail with care is while handling it. Its eye-catching pointed leaves covering draping stems are actually extremely fragile and can break off with even the slightest touch. For that reason, it's best to choose a sunny spot to place or hang your donkey's tail succulent and then, quite literally, forget about it.

As with many succulents, donkey's tail thrives best with lots of warm sunlight, though it will tolerate a partial shade location. If you're choosing to house your plant indoors, opt for a sunny windowsill that boasts several hours of daily light. If you're growing your succulent outdoors, place it in a pot or spot in your garden that gets plenty of morning sunlight but is partially shaded during the more aggressive afternoon hours to avoid scorching its leaves.


In order for your donkey's tail succulent to grow successfully, it should be housed in well-draining, sandy soil. If you plan to plant your succulent in a container (either to keep outdoors or to live inside), opt for a gritty soil mixture suited specifically for cacti or succulents. Choose a container with a drainage hole to ensure the roots don't sit in water. If you're including it as part of a larger garden, be sure to choose a spot amongst other plants that prefer well-drained soil, as too much retained water will cause it to die (you can even consider mixing sand into your ground soil to aid in drainage). Additionally, donkey's tail thrives in soil with a neutral to alkaline pH but isn't too picky in this regard.


When it comes to watering your donkey's tail succulent, less is more. Like many succulents, donkey's tail is drought resistant once established, so you'll want to water it more frequently during its spring and summer growing season, then taper off throughout the fall and winter months. Generally, opt for a single heavy watering each month if your plant is indoors, increasing to once every two or three weeks if you're housing your succulent outdoors. A good rule of thumb: The soil of your succulent should dry out completely in-between waterings. Check the soil with your finger to make sure the soil is dry at least an inch down before watering the plant.

To aid in drainage, choose a pot with holes at its base; a terracotta or clay material can also help wick water from the soil. When in doubt, err on the side of less watering rather than more—donkey's tail holds moisture in its plump leaves and can tolerate periods of drought but is not at all tolerant of over-watering. The leaves will also begin to pucker like a raisin, indicating that it's time to water.

Temperature and Humidity

Donkey's tail prefers warm weather, though it stands up better to cooler temperatures than some other succulents. On average, try to maintain an environment of 65 degrees to 75 degrees Fahrenheit whether you keep your plant indoors or outdoors. It can survive when exposed to temperatures as low as 40 degrees Fahrenheit, but only briefly, so be sure to bring it inside before the first frost or move it away from drafty windows in the winter months.

When it comes to humidity, donkey's tail has no special needs. In fact, it prefers average levels of humidity and can rot if attempts are made to increase the humidity of its environment (so no need to mist its leaves or keep it somewhere more humid, like a bathroom).


While fertilizing donkey's tail succulent isn't necessary for its successful growth, it also won't hurt and can be a great way to give the plant added nutrients. Focus on feeding your plant at the beginning of its growing season in spring, using a controlled-release, balanced 20-20-20 fertilizer, which contains equal parts nitrogen, phosphorus, and potassium. Mature succulents may prefer the fertilizer at one-quarter strength, while younger plants may prefer fertilizer with less nitrogen.

Types of Donkey's Tail

There are two closely related forms of this plant.

  • Sedum morganianum, the species form, is usually known as "donkey's tail", and it can be identified by its notably pointed leaves.
  •  S. morganianum 'Burrito' is the only named cultivar sold, usually marketed as "burro's tail." It is identified by its more rounded leaves. Other than this, the plants are identical.


Should stems grow sparse from leaves that drop off, you can clip off the stem near the plant crown. Otherwise, no pruning is necessary—unless to harvest leaves for propagating new plants.

Removing leaves from a portion of the stem can sometimes stimulate side-branching at this point.

Propagating Donkey's Tail 

Since donkey's tail rarely flowers indoors, propagating by seed isn't a viable option. But, like most succulents, donkey's tail is easy to propagate through stem cuttings or by its leaves which is good news, as they seem to fall off at the slightest touch.

How to propagate by stem cuttings:

  1. With a sterilized cutting tool, snip off a plump and healthy stem that measures a couple of inches.
  2. Take off the bottom few leaves (and you can propagate those, too).
  3. Place the stem in a shallow box or box top, place it in a room with bright light, and let it heal and develop a callus before planting. This should take a couple of weeks. However, some gardeners will put the cutting directly into succulent potting mix without letting the callus develop.
  4. Stick the stem into a pot that you would like to keep the plant in for a while. Fill it with cacti or succulent potting mix. Keep it in a space with indirect light.
  5. Water only when the soil is dry.
  6. Roots can develop in a couple of weeks.

How to propagate by leaf cuttings:

  1. If you notice your plant has shed some of its leaves recently, simply put aside healthy plump ones until the skin has callused over, about two to three days. Avoid working with shriveled or damaged leaves.
  2. From there, fill a pot with cacti or succulent potting mix. Lay the leaves on top of the soil, making sure they make contact with the medium.
  3. Mist regularly (about once a week), making sure the soil stays moist but not soggy, until you see new growth start to emerge. Then, reduce watering and treat the new plant as you would an established plant. Young plants do need more water than mature plants until they're established, but be careful not to overwater.

Potting and Repotting Donkey's Tail

Because of their fragile nature, great care should be taken when repotting a donkey's tail succulent. Wait until it's absolutely necessary. The plant doesn't mind being a bit root bound, so you'll only need to repot once every few years. Be careful to avoid losing many of your "tails" and leaves to jostling when replanting. However, if you must repot your succulent, you will find the most success in the warmer months. Make sure the soil is completely dry before beginning, then gently remove the succulent from its current vessel, knocking away any old soil from the roots of the plant. Place it in a new pot (a shallow clay pot works best) and backfill with soil, making sure to spread out the roots in the new, larger pot. Allow it to "rest" for a week or so before giving it the first watering in its new home.


Whether you are growing donkey's tail indoors as a houseplant or outdoors in a climate where it is hardy, reduce watering to every other month in the winter and omit feeding during this period of low growth.

Common Pests & Plant Diseases

The donkey's tail succulent is not particularly susceptible to pests, but if it does experience an infestation, it's likely to be from aphids. Though aphids can typically be hosed off a plant, that's not the best solution for donkey's tail succulents given their fragile nature. Instead, opt to mist them every few days with diluted organic neem oil until the aphids disappear (typically around two to three weeks). Mealybugs can also be an issue and can also be handled with neem oil.

When planted outdoors, slugs and snails can be a problem, best handled by picking them off by hand or setting out baits for them.

The only significant disease problem is root rot, which can occur if the plant is overwatered or grown in dense, poorly draining soil.

How to Get Donkey's Tail to Bloom

This plant blooms infrequently, especially when grown indoors, and they are not likely to bloom at all until they are quite mature. The small, yellow, white, or red flowers, when they do appear, bloom in late spring or early summer. The flowers are not especially showy, but growers have noticed that slightly stressing the plant with cooler outdoor temperatures (though not to such excess that it endangers the plant) sometimes stimulates them to bloom.

These plants also need plenty of sunlight to bloom, but feeding should be kept at a minimum.

Common Problems With Donkey's Tail

Donkey's tail is a largely problem-free plant that thrives on neglect, but several cultural issues may raise questions:

Leaves Turn Gray

If you notice your plant turning grey or a very dull green (rather than its typical rich blue-green), that's probably a sign that it's getting too much harsh light. You may also notice a chalky white, waxy appearance on the beaded leaves of your donkey's tail succulent. Don't stress—it's a completely normal occurrence called epicuticular wax, which the plant produces to protect itself from too much harsh sun exposure.

Leaves Shrivel and Shrink

When the leaves of donkey's tail curl up and shrink, it is usually because the plant needs water. This is not such a big problem, as they will soon swell up again as soon as you give it a thorough watering. Many growers find that it's better to wait for this sign before watering than to water too frequently.

Stems Turn Soft and Collapse

If the stems on your donkey's tail collapse and turn soft, it's likely because the plant has been overwatered and rot is setting in. If you immediately allow the plant to dry out, it sometimes can be saved, but with advanced cases of rot, you'll need to discard the plant.

Leaves Wilt, Fall Off

If you notice leaves drooping and beginning to fall off, don't mistake this as a sign the plant needs water—with donkey's tail, this is actually a sign that the plant is overwatered.

  • How can I use this plant in the landscape?

    Donkey's tail is most commonly grown in containers, especially in hanging baskets where the trailing stems display to best effect. Potted plants are readily moved back and forth between indoor and outdoor locations with the change in seasons. In warmer climates, it can also make a good garden plant to trail over garden walls or banks. When using it as a hanging plant, make sure to place it out of the way so that it can't be brushed against and damaged.

  • Does donkey's tail make a good ground cover?

    Because it looks similar to many sedums that are commonly used as ground cover plants, donkey's tail is sometimes planted with that purpose in mind. But this is a fairly delicate plant that is easily damaged and does not tolerate any foot traffic at all.

  • Are there other sedums with a similar look that are cold-hardy?

    Several sedums with similar-looking leaves are hardy up to zone 4. Try Sedum album, S. divergens, or S. reflexum, all of which make good cold-hardy ground cover plants.

  • Is donkey's tail toxic to pets?

    Donkey's tail (Sedum morganianum) is safe and not toxic to pets. However, there is another plant, Euphorbia myrsinites, that has the same common name of donkey's tail, and this perennial is toxic to pets.

  • Does touching succulents hurt them?

    Succulent leaves are fleshy but delicate. They can be damaged and scratched easily so it's best to avoid touching them.
