Small succulent, big weakness for velvet. 🌿
Family: Crassulaceae · Pot diameter: 5.5 cm
Crassula mesembryanthoides ‘Tenelli’ is a small succulent with narrow, elongated leaves dressed in very fine hairs. Their soft surface catches the light and shifts the green towards a silvery, almost frosted tone.
The leaves form in opposite pairs along slender stems, gradually building a dense, upright and branching silhouette. The precision of their arrangement and velvety texture give ‘Tenelli’ a character best appreciated up close.
Its distinctive appearance comes from three genuine characteristics: the hairy surface, opposite leaf arrangement and slender, upright branching habit.
Numerous fine hairs cover every narrow leaf, creating a soft, luminous surface without hiding its green colour.
The leaves appear in pairs, with each new pair changing direction to form a regular crossed pattern around the stem.
The slender, fleshy stems branch and fill out, allowing the young plant to develop into a compact succulent clump with a clear vertical line.
Why you’ll love it: it combines the clean outline of a small succulent with an unexpectedly soft texture that invites a second look — not a touch.
On a very bright shelf or near a window, where side light picks out the fine hairs without visually flattening their texture. A small pot in deep green, terracotta or matt charcoal creates a crisp contrast with the silvery-green surface.
Create an arrangement of contrasting lines and textures with succulents that appreciate abundant light, good drainage and a clear drying interval. Keep each species in its own pot so its watering can follow its own rhythm.
A very bright position with filtered light or gentle morning sun. Any stronger exposure requires gradual acclimatisation.
Water deeply once the mix has dried well, then allow all excess water to drain away. No small, frequent sips.
Good airflow and leaves that remain dry. Protect it from frost, prolonged cold and stagnant humidity.
There are insufficient cultivar-specific data. Keep it out of reach and seek veterinary advice in the event of possible ingestion.
Place it in a very bright position with abundant indirect light and, if it is already acclimatised, gentle morning or late-afternoon sun. Do not move it abruptly from indoors into strong summer midday sun — especially behind glass — because the leaves can become marked.
Wet the entire root zone evenly and allow the water to run from the drainage holes. Repeat only once the mix has dried well and the pot feels noticeably lighter. Light, temperature, season and root size all change the drying time, so there is no safe fixed schedule in days.
The dense, hairy surface holds droplets and dust, so avoid misting and closed terrariums. Water the substrate without repeatedly wetting the foliage and provide airflow, especially when the room is cool or evaporation is slow.
The usual warm conditions of a bright home suit it, but it needs protection from frost and prolonged cold. There is no documented obligatory summer dormancy for ‘Tenelli’. Watch the new growth: when it slows because of heat, low light or season, leave the mix dry for longer and stop fertilising.
Use a porous, airy cactus and succulent mix that does not compact and drains excess water quickly. The pot must have drainage holes and should be only slightly larger than the root system.
If you have just repotted into Sybasoil Cacti & Succulent Premium Mix, use its initial nutrition first for about two months. Afterwards, and only while you can see active growth, use Cactus&Succulent Focus at the label rate and water with plain water between applications. Repot once the roots have filled the pot, and hold the fragile fuzzy stems at the base without rubbing them.
The RHS lists Crassula mesembryanthoides ‘Tenelli’ PBR as an accepted name in the family Crassulaceae. Kew accepts the species Crassula mesembryanthoides (Haw.) D.Dietr.; this is also the correct spelling of the specific epithet.
It is a named cultivar, and the RHS notes plant breeders’ rights (PBR) without publishing a breeder or introducer, parents or selection method, place and date of first introduction, or the PBR number or rights holder. A cultivation note from 2015 proposed a hybrid origin based on floral characteristics, but it identified no parents and provided no pedigree evidence. The hypothesis remains unconfirmed and does not replace the RHS’s current accepted placement under Crassula mesembryanthoides.
Kew records wild Crassula mesembryanthoides as native to the south-eastern Cape Province of South Africa and as a terrestrial succulent subshrub of the subtropical biome. SANBI assesses wild Crassula mesembryanthoides subsp. mesembryanthoides as endemic to the Eastern Cape and Least Concern. These data concern wild populations; they do not mean that the commercial ‘Tenelli’ grows wild there or establish its placement within a subspecies.
From natural habitat to care: ‘Tenelli’ is a cultivar, not a wild plant; its ecological reference is Crassula mesembryanthoides, under which the RHS places it. The wild species is a terrestrial succulent subshrub from the subtropical south-eastern Cape Province. In a pot, the conservative interpretation is abundant light, a porous mix and a cycle of deep watering followed by thorough drying, without labelling the cultivar summer-dormant or keeping the root zone permanently wet.
Each node bears two opposite leaves, and the next pair turns by approximately a right angle. This arrangement, known as decussate phyllotaxy, creates the symmetrical rhythm around the stem.
The fuzzy appearance comes from numerous fine epidermal trichomes. By scattering and reflecting light, they make the green leaf appear greyer or more silvery.
In ‘Tenelli’, the leaves are narrow to linear, with an acute tip and an entire — untoothed — margin. Their fleshy interior forms the main water-storage tissue.
Kew describes the species as a succulent subshrub. Its upright form is built from repeated leafy stems, while the older lower sections can gradually harden and become woody.
Useful answers about light, watering, compact growth, the fuzzy surface and pets.
Once acclimatised, it can take gentle morning or late-afternoon sun. Do not move it abruptly from indoors into strong summer midday light, especially behind glass. Increase exposure gradually and pull it back if bleached or brown patches appear.
When the mix has dried well at depth and the pot feels noticeably lighter. Water evenly until it runs from the drainage holes, then let it drain. Check the substrate rather than counting days, because the pace changes with light, temperature and season.
Longer internodes, sparser leaves and a strong lean in one direction are often associated with insufficient or one-sided light. Move the plant gradually to a brighter position and turn the pot a little from time to time. New growth can become denser, but already elongated sections will not shorten.
No obligatory summer dormancy has been documented for ‘Tenelli’. It may, however, slow down in extreme heat or when conditions do not support new growth. Then reduce watering frequency while checking that the mix dries, and do not fertilise until active growth appears again.
No. Misting traps water among the fine hairs without meaningfully watering the roots. Remove dust gently with a dry, very soft brush, and avoid a wet cloth or vigorous rubbing.
There are insufficient cultivar-specific safety data to describe it responsibly as either safe or toxic. Keep it out of reach and, if chewing or ingestion occurs, contact a veterinarian and provide the plant’s full botanical name.
