Sedum sieboldii (aka October Daphne or Hylotelephium sieboldii) is a deciduous succulent plant hailing from Japan.
The flowering Sieboldii October Daphne is a bright pink plant is named after a German researcher of Japanese botany during the 1800s, Franz Philippe von Siebold.
October Daphne is just one of many different types of the genus, and it is often thought of as being the most beautiful.

The Sedum sieboldii is a small, attractive plant with a low, spreading growth habit.
Sieboldii grows in attractive, circular mounds and sends out horizontal branches from a central crown. The blue-green leaves are about three quarters of an inch around and grow in sets of three.
Leaf edgings are deep pink, and this flower color intensifies as the growing season progresses into late summer and fall. When the plant gets the right amount of light, fall leaf color may be pink, orange, yellow or even bright red.

How To Propagate The Stonecrop Sedum sieboldii
Propagation of Sedum seiboldii is extremely easy.
Grow new sedum plants from:
- Softwood cuttings
- Plant propagation through division

Early spring is the best time to divide this plant.
Stonecrop Pests or Disease Problems
When growing outdoors, plants may have problems with slugs and snails. Prevent slugs and snails by:
- Picking off these individual pests
- Working the ground around the plant regularly
- Using slug and snail bait
- Introducing nematodes to the soil to help control the pests
Excessive watering may cause bacteria and fungus to grow.
Fungus, in turn, may cause damaged roots, and withering and discoloration of shoots and leaves. Reduce watering and provide well-draining soil.
Aphids, mealy bugs and/or scale insects may also be a problem in an outdoor or indoor setting.
Outdoors aphids, mealybugs and scale insects are best dealt with them by encouraging natural predators such as parasitic wasps, ladybugs and the like.
Indoors, these pests may be washed off with a strong spray of water and/or scraped off. Discourage them with occasional treatments of neem oil and water.
Outdoors vine weevils may also be problematic. Remove them by handpicking, treating with a neem oil solution and introducing nematodes to the soil.
