Sedum

Sedum spp.,Stonecrop, Autumn Joy Sedum, Burro's Tail, Donkey's Tail

Sedum is a vast genus of succulents belonging to the Crassulaceae family, native to various regions globally, though many popular species are native to Mexico. They are incredibly diverse, ranging from low-growing groundcovers to upright, clumping plants. All species are characterized by thick, fleshy leaves that store water, making them highly drought-tolerant. They are extremely popular for their resilience, ease of propagation, and often colorful foliage, which includes shades of blue-green, yellow, pink, and burgundy, especially when exposed to bright sun or cooler temperatures. Popular cultivated varieties include S. morganianum (Burro's Tail), S. rubrotinctum (Jelly Bean), and S. rupestre 'Angelina'.

Care Guide

LIGHT

  • Requires bright light, including direct sun, to maintain compact form, prevent stretching, and enhance vibrant leaf colors (reds, pinks, yellows).
  • Place in a South or West-facing window for best results.
  • Insufficient light causes stretching (etiolation), making the stems sparse and the leaves pale.
  • When grown indoors, most varieties benefit from the brightest available light.

WATER

  • Highly drought-tolerant. Overwatering is the biggest risk and causes mushy leaves and stem rot.
  • Water thoroughly and deeply, then allow the soil to dry out completely and remain dry for at least one to two weeks before watering again.
  • The leaves will often look slightly deflated or wrinkled when the plant is thirsty.
  • Reduce watering drastically in the fall and winter dormancy.

SOIL

  • Needs an extremely fast-draining, gritty, and lean soil mix.
  • Use a mix formulated for cacti and succulents, with a high percentage of pumice, perlite, or coarse sand.
  • Heavy potting soil will retain too much water.

GROWTH HABIT

  • Ideal conditions: Full sun, warm temperatures (65-80F), and low humidity.
  • Growth rate & size: Growth rate is slow to moderate, depending on the variety. Forms vary widely from trailing stems to upright clumps.

PROPAGATING

  • Propagates extremely easily from leaf cuttings or stem cuttings.
  • Leaf Cuttings: Gently twist a leaf off and allow it to callus (dry) for a few days, then place it on top of dry soil until roots and a new plant form.
  • Stem Cuttings: Cut a stem, allow it to callus, and plant it in dry, gritty soil.

PRUNING

  • Pruning is often necessary to control the shape and deal with legginess.
  • Cut back leggy stems to encourage bushier growth and use the cuttings for propagation.
  • Trailing varieties (like Burro's Tail) require minimal pruning, only removing broken or damaged strings.

REPOTTING

  • Repot infrequently, typically every 2-3 years, as they are slow-growing and prefer to be slightly pot-bound.
  • Repot in spring or early summer.
  • Use a shallow pot (especially for trailing varieties) only slightly larger than the root ball, and refresh the gritty soil.

FERTILIZING

  • Fertilize very sparingly during the spring and summer growing season (once or twice per season).
  • Use a liquid fertilizer formulated for succulents diluted to half strength or less.
  • Do not fertilize in fall or winter.

FLOWERING

  • Produces small, star-shaped flowers in clusters, often pink, yellow, or white, typically in late summer or fall.
  • Flowering is a sign of a healthy, mature plant.

TOXICITY

  • Most Sedum species are considered non-toxic or only mildly toxic, but the safety varies widely; it's best to keep them away from pets that chew.

PRO TIPS

  • Leaf loss is common on trailing varieties (like Burro's Tail); this is normal, and fallen leaves can be left on the soil to propagate.
  • If the plant is turning pale green or stretching, it is desperate for more sunlight.
  • Watering only when the leaves visibly wrinkle is the safest way to prevent rot.

Variability in Care

Trailing Varieties

Examples: Sedum morganianum (Burro's Tail), S. dasyphyllum

  • Best grown in hanging baskets to allow the long stems to cascade.
  • Very sensitive to rough handling, which causes the leaves to drop easily.

Clumping/Upright Varieties

Examples: Sedum x 'Autumn Joy', S. rubrotinctum (Jelly Bean)

  • These have a more upright, bushy habit and are easier to manage in standard pots.
  • The leaves of 'Jelly Bean' are famous for turning bright red under full sun and mild stress.

Groundcover Varieties

Examples: Sedum rupestre 'Angelina', S. acre

  • These are often smaller and grow closer to the soil.
  • Very tolerant of cold but require the same high light indoors.
