Key Identifying Features
Donkey Tail, or Burro's Tail (Sedum morganianum), is a trailing succulent recognized at a glance by its long, rope-like stems completely covered in plump, overlapping leaves that resemble a braided or scaly tail.
- Trailing stems up to 60 cm or more, hanging straight down
- Densely packed, fleshy, teardrop leaves spiraling around each stem
- Blue-green to grey-green color with a powdery, waxy bloom (farina)
- Leaves drop very easily at the slightest touch
Leaves & Stems
Each leaf is 1.5–2.5 cm long, plump, pointed-oval (lanceolate), and fleshy, curving slightly upward. They overlap like fish scales or braided rope, hiding the stem entirely. The signature silvery-blue waxy coating (farina) rubs off where touched, leaving fingerprints — a reliable ID and handling clue. Stems are weak and pendant, which is why the plant is grown in hanging pots. A closely related, more common plant, Sedum × Burrito (Baby Burro's Tail), has shorter, rounder, more tightly packed leaves with blunt tips — often what is actually sold as donkey tail.
Flowers & Fruit
Mature, happy plants produce small, star-shaped flowers in red, pink or pale red clustered at the tips of the trailing stems, usually in summer. Flowering is occasional indoors and a pleasant bonus rather than a primary ID feature.
How to Tell It Apart from Look-Alikes
- vs. Sedum × Burrito (Baby Burro's Tail): that has rounder, blunt, tighter leaves; true morganianum has longer, pointed, more spaced leaves
- vs. String of Bananas/Pearls (Senecio): those have widely spaced, individual round or banana-shaped beads on thin bare stems, not a solid sleeve of leaves
- vs. Sedum 'Donkey' uprights: many sedums are upright; donkey tail is distinctly pendulous
Where You'll Find It
Almost exclusively a houseplant or patio plant in hanging baskets, where the tails can dangle freely. Native to southern Mexico (Veracruz), it grows on shaded rocky cliffs and ledges.
Quick ID Checklist
- Long pendant stems hanging like tails
- Plump teardrop leaves overlapping all around the stem
- Blue-green color with powdery waxy bloom
- Leaves detach at the lightest touch
- Grown in a hanging pot, trailing downward
Frequently asked questions
Why do the leaves fall off so easily?
Donkey Tail leaves are very loosely attached as a natural propagation strategy — dropped leaves root and form new plants. Handle the trailing stems as little as possible.
What is the silvery coating on the leaves?
It is a natural waxy bloom called farina that protects against sun and water loss. It rubs off where touched, leaving visible fingerprints.
How do I tell Donkey Tail from String of Pearls?
Donkey Tail stems are completely sleeved in overlapping plump leaves, while String of Pearls has separate round beads spaced along a thin bare stem.
Is my plant true Sedum morganianum or the 'Baby' version?
True morganianum has longer, pointed, slightly spaced leaves. The common Sedum × Burrito has shorter, rounder, blunt, tightly packed leaves.
