The white succulents Succulents are a group of plants highly valued in gardening and decoration for their elegance and unique appearance. Although pure white species are particularly rare in nature, there are numerous types of succulents that appear white due to a layer of wax or bloom that covers their leaves and stems. This layer serves an essential function: it protects them from intense solar radiation in their native habitats and also reduces water loss, helping them survive in arid environments.
Do you want to know the names of these white succulents and how to care for them so they look healthy and spectacular? In this comprehensive guide, you'll find detailed information on the most popular species, as well as all the steps and expert advice for keeping them pristine, from the right substrate to how to water them properly, adapt them to different spaces, and protect them from pests and diseases. We also share inspiring photographs so you can recognize them and add them to your collections.
Types and varieties of white succulents
If you'd like to add a sophisticated touch to your home, balcony, or garden, white succulents come in a wide range of shapes, sizes, and hues. Below is a selection of the most popular species:
caputia tomentosa
Popularly known as woolly senecio or snow succulent, the caputia tomentosa It is native to the Cape (South Africa). Its fleshy leaves, covered in a dense whitish wax, grow vertically and can reach between 10 and 25 cm in height. Although it blooms, its flowers go unnoticed because they are whitish, like the plant itself.
Cotyledon orbiculata
This Cotyledon is a succulent shrub that can grow to 1,5 metersWith branched stems, it develops glaucous green leaves with red margins and both sides covered in white wax. It blooms in spring with orange or yellow flowers on stems up to 60 cm tall.
Cotyledon undulata
This African species is a small shrub that can reach 50 cmIt branches from the base and is notable for its scallop-shaped leaves, covered with a whitish layer of wax. If it receives more sunlight than usual, its leaves may acquire a reddish hue on the edges and undersides. Its flowers, in spring, are orange or yellow.
Dudleya brittonii
Native to Mexico, the Dudleya brittonii forms rosettes of fleshy triangular leaves covered with waxIt can reach 1 meter in height, although it generally remains more compact. The greenish flowers sprout on 30-35 cm stems.
Farinosa dudleya
Native to Oregon and California, this Dudleya forms rosettes of light green leaves, with a diameter of up to 6 cm and a height of 5 cm. It displays numerous, small, yellow flowers in spring and summer.
Echeveria sings
La Echeveria sings It is one of the most striking species due to the size of its rosettes: up to 30 cm in diameter and 50 cm in height. Its color ranges from glaucous green to whitish depending on the amount of wax present. It produces pink flowers in spring.
echeveria laui
Echeveria laui is a rosette native to Mexico that grows to about 30 cm in diameter and 5-7 cm in heightIts leaves are fleshy and dark green, almost hidden by the white wax covering them. It blooms in spring with pink flowers at the end of a 10 cm stem.
Senecio candicans 'Angel Wings'
Known as Senecio 'Angel Wings', this hybrid can reach 1 meters tall (less so if pruned). Its leaves are large and green, but with a dense layer of white powder on both sides and serrated edges. Its orange-yellow flowers bloom during the winter.
How to care for white succulents?
The secret to keeping your white succulents looking healthy and attractive is to replicate their natural habitat as closely as possible. Beyond watering, there are several factors to consider: Substrate, light, location, temperature, fertilizer, and pest and disease preventionHere's a practical and detailed guide:
Location and Light
Where you place your white succulents is essential. They need plenty of natural light to maintain their compact shape, color, and growth. Ideally, they should receive at least 6 hours of direct or indirect sunlight per dayIf they are indoors, place them near a south, east, or west-facing window where the sun shines through most of the day.
If you've had your succulents indoors and want to acclimate them to the outdoors, do so gradually: increase sun exposure by one hour per day each week, preferably in spring or fall, to prevent them from getting burned by intense sun.
In the colder seasons or in case of frost, many succulents tolerate low temperatures (up to a few degrees below zero), but it is preferable protect them indoors If there is a risk of severe frost or excessive rain, avoid placing them next to heat sources such as radiators, as sudden temperature changes can stress them. If they are outdoors and you expect frost, cover them with plastic or glass to create a small greenhouse that maintains heat and humidity, while also ensuring good ventilation when temperatures rise outside.
Can they be inside the house?
White succulents can be grown indoors, as long as the room is very bright and preferably with direct sunlight. A poorly lit location will cause unsightly elongation and loss of color (a process known as etiolation). If there is frost, indoors is the best option, avoiding placing them too close to heaters.
Soil and substrate for white succulents
The substrate should be very light and drain water quickly., since excess moisture causes root rot. You can use commercial mixes specifically for cacti and succulents, or prepare your own substrate with the following expert-recommended recipe:
- 2 parts potting soil (or black soil)
- 1 part solid humus
- 3/4 part coarse sand (never beach sand, it may have salt)
- 1/2 part vermiculite
- 1/2 part perlite
- 1/2 part charcoal (improves drainage and prevents mold)
Mix all of these ingredients and fill the pot, making sure it has drainage holes. If you're planting in the garden, make sure the soil doesn't become waterlogged and is very loose.
Watering: frequency and tips
Irrigation is The most delicate aspect of caring for white succulentsWater only when the substrate is completely dry. The frequency varies depending on the season and environmental conditions: in summer it may be once a week, while in winter, once every 2, 3, or even 4 weeks is sufficient.
- Always wait until the substrate is dry to a depth of 2-3 cm. You can check this with a toothpick, a moisture meter, or simply by inserting your finger.
- Water deeply, until water runs out of the holes in the pot.
- Avoid wetting the leaves, especially those of species covered in bloom: humidity encourages fungi and the loss of the whitish layer.
- In winter, reduce watering to a minimum. The plant enters dormancy, and the soil takes much longer to dry.
- Observe the plant's signs: wrinkled or dehydrated leaves indicate a lack of water; yellow or translucent leaves indicate overwatering.
Excess water is the biggest enemy of succulents, as it rots their roots. If you grow outdoors and it rains heavily, keep the pots covered, especially if they don't have good drainage.
Fertilization and fertilization
During spring and summer, when succulents are growing, feed every 3 to 4 weeks using specific fertilizers for cacti and succulentsAvoid fertilizing in fall and winter, when the plant is dormant. If you prefer organic fertilizers, use very small amounts of well-sifted worm castings.
Transplant and reproduction
Repot every 2 or 3 years or when the plant has filled all the available space. The best time is spring, when it resumes active growth. When repotting, remove rotten roots and let the plant dry out of the substrate for a few hours to prevent infection.
White succulents are also easily propagated from leaf, stem, or sucker cuttings. Let the cutting dry for a couple of days before planting it in dry soil, avoiding watering for the first few weeks.
Resistance to cold and heat
Most white succulents tolerate high temperatures and brief drops to -2ºC/-4ºC., but it's essential to protect them if the temperature drops further or if there's heavy rain. If they're outdoors during the winter, create a microclimate by protecting them with frost-resistant fabric, plastic, or glass, and ventilate them if temperatures rise. Sudden changes and constant humidity are the greatest risks.
Prevention of pests and diseases
White succulents are generally hardy, but can be affected by:
- Cottony cushion scale and shield scale: Appears as small white or brown bumps on leaves and stems. Remove manually with an alcohol-soaked swab or apply a specific insecticide for succulent plants.
- Fungi and rot: Caused by overwatering or lack of ventilation. If you see soft or black spots at the base of the plant, cut off the affected part and apply fungicide. Improve drainage and reduce watering frequency.
- Snails and slugs: They can chew through leaves, especially outdoors. Remove manually or use physical barriers if there is an infestation.
Expert tips for growing white succulents
- Avoid handling leaves covered in pruina: it is easily erased and does not regenerate in the same way, detracting from the plant's beauty.
- To maintain a compact and symmetrical shape, rotate the pot periodically if it receives side light.
- In humid spaces, ventilate daily and use even more draining substrates.
- If you grow in offices or air-conditioned spaces, keep succulents away from direct currents and check your watering regime: the environment can dry out the substrate more quickly than usual.
Frequently Asked Questions About White Succulents
- Why is my white succulent changing color? Sunlight intensity, water stress, or temperature changes can cause them to develop reddish tones or lose their whitish color. Maintain a consistent exposure and avoid sudden changes to preserve their colors.
- Can I recover a white succulent with soft leaves? If the leaves are soft and translucent, reduce watering, improve drainage, and let the soil dry thoroughly. Cut and remove any damaged parts and wait for the plant to recover.
- What do I do if the leaves are dusty? The whitish layer is natural and protective; don't wipe it off; just brush off the dust with a soft, dry brush to avoid damaging the wax.
White succulents, with their delicate hues and hardiness, are among the most rewarding and attractive plants for both gardening experts and beginners. They require very little care if you respect their need for light, good drainage, and controlled watering. This guide provides all the keys to ensuring they look impeccable and become a part of your decor with personality and originality.
