How we ship our plants

Most of our plants are shipped bare-root. Please note that the plant you receive may not be an exact likeness of the images shown.

Le Cotyledon orbiculata undulata, aussi connu sous le nom de couronne d'argent, est une succulente très sculpturale. Comme vous pouvez le voir, elle produit ces incroyables feuilles en forme de coquille d'huître qui se chevauchent parfaitement. Chaque feuille est recouverte d'une poussière argentée (pruine) qui la protège des rayons du soleil intenses.

Avec le temps, elles produiront des rejets. Elles produisent également un magnifique éventail de fleurs orange et jaunes en forme de clochette sur une longue tige florale du milieu à la fin de l'été.

Toutes les espèces de Cotyledon sont originaires d'Afrique du Sud et semblent être semi-rustiques. Le Cotyledon orbiculata a été connu pour survivre à des températures aussi basses que -6°C pendant de courtes périodes.

Elles font de superbes succulentes en pot seules ou vous pouvez les essayer avec un mélange d'autres succulentes comme les Echeveria, les crassula et les sempervivums pour créer votre propre petit paysage de succulentes à faible entretien.

On Arrival

Cotyledon orbiculata undulata is delivered bare-root and will need time to establish in its new pot. Unpack it carefully, remove all protective material and check the leaves, stems and roots have arrived in good condition.

Plant Cotyledon orbiculata undulata in fresh, free-draining compost, spreading the roots naturally rather than forcing them in. Keep every healthy leaf and the growing point above the surface, then tap the pot on the bench to settle the mixture without pressing it down hard.

Wait five to seven days before watering so small root injuries from lifting and transport can dry. After that, water lightly while the roots establish and move to the normal 3 D's routine once the plant is firmly rooted. Keep Cotyledon orbiculata undulata bright, sheltered and out of fierce midday sun while it settles.

Watering

Water Cotyledon orbiculata undulata using our 3 D's method: drench, drain and dry. Water thoroughly so the whole root area is moistened and every excess drop escapes through the drainage holes, then wait until the compost has dried before watering again.

Judge watering by the compost and the weight of the pot rather than a fixed timetable. A small terracotta pot in bright warmth dries quickly, while a large or glazed pot stays wet far longer. Water in the morning and avoid leaving water sitting in the centre of a rosette.

Reduce watering considerably through cold, dull weather. Fleshy leaves and stems store moisture, so a healthy plant tolerates a dry spell far more safely than cold, permanently wet compost.

Light and position

Provide Cotyledon orbiculata undulata with Plein soleil - Plus de 5 heures d'ensoleillement. Suitable positions can include Table d'extérieur, Véranda et Rebord de fenêtre ensoleillé. Most succulents need strong natural light to keep compact growth and their best Blanc colouring; too little light causes stretched, pale, leggy growth.

Rotate a pot-grown plant regularly so it develops evenly, and introduce it to stronger sunshine gradually after winter, delivery or a spell indoors, as unadjusted foliage can scorch. Provide temporary shade during intense heatwaves.

A few succulents prefer bright indirect light rather than fierce sun. If Cotyledon orbiculata undulata's leaves bleach or brown in strong summer sun, move it to a slightly shadier spot.

Compost and drainage

Plant Cotyledon orbiculata undulata in a free-draining mixture. A standard multi-purpose compost or a John Innes No.2 (sandy) mix with around 30 to 40 percent by volume of drainage media, such as horticultural grit, sharp sand or perlite, suits most succulents well. Always choose a pot with unrestricted drainage holes.

Choose a container only moderately larger than the root system, as surplus compost stays wet for too long. Terracotta is a useful choice in the cool, humid UK climate because its porous sides help the compost dry evenly.

A thin layer of horticultural grit around the base keeps the lowest leaves off damp compost and helps the surface stay open and airy.

Feeding

Fresh compost should contain enough nutrients to support Cotyledon orbiculata undulata for approximately three to six months. Once these are used, apply a balanced liquid feed at half the recommended strength every two to four weeks while the plant is in active growth.

Feed only when the compost is already moist, preferably shortly after watering. Stop feeding through autumn and winter, or whenever growth has paused.

Do not overfeed to force colour or size. Strong light, sharp drainage and correct watering matter far more than fertiliser.

Winter care

The recorded minimum temperature for Cotyledon orbiculata undulata is -6°C. Unless the product page confirms it is hardy, treat Cotyledon orbiculata undulata as tender and move it into a bright, airy, frost-free position before conditions fall below its recorded minimum.

Keep the compost much drier through winter, as cold, wet roots rot readily. Avoid standing the plant above a radiator, where dry heat and weak light cause soft, distorted growth. A greenhouse, conservatory or bright, cool windowsill gives good protection.

Where Cotyledon orbiculata undulata is genuinely hardy, its main enemy is winter wet rather than cold: keep drainage sharp and clear wet debris from around the crown.

Summer care

Spring and summer are the main growing season for most succulents, so check the compost regularly and water thoroughly whenever it has dried. Many can spend the frost-free months outdoors once acclimatised gradually to sun, wind and rain.

Ventilate greenhouses and conservatories in hot weather, as heat trapped behind glass can scorch leaves. Provide temporary afternoon shade during exceptional heatwaves.

Strong light often deepens red, bronze and purple tones. If Cotyledon orbiculata undulata flowers, enjoy the display and remove the dried stems afterwards if you prefer a tidier plant.

Repotting

Repot Cotyledon orbiculata undulata in spring when the roots fill the pot, the plant becomes unstable or the compost has broken down. Ease it out while supporting the base rather than the leaves, and remove as much old compost as possible.

Inspect the roots and cut away any brown, hollow or soft ones with clean snips, leaving fresh cuts to dry. Replace with a fresh, free-draining mixture in a pot only one or two sizes larger.

Keep Cotyledon orbiculata undulata at its previous depth and wait three to five days before watering so any root injuries can seal.

Common problems

Stretched, pale, widely spaced growth almost always means Cotyledon orbiculata undulata needs more light. Move it gradually somewhere brighter and rotate the pot.

Soft, translucent, mushy leaves, a darkening stem base or sudden collapse point to excess moisture and rot. Remove the plant from wet compost, cut away damaged tissue and roots, and let healthy material dry before repotting or taking rescue cuttings.

Check leaf joints and the root area for white, cotton-like mealybug, which shelters in sheltered spots. Isolate and treat affected plants promptly. Dry brown patches usually indicate sun scorch, so introduce direct light gradually.
