This is without a doubt, the most beautiful of all sedums. Sturdy, non -invasive, super hardy, and reliable. It not only looks fantastic in bloom, but the grey/blue/green foliage is attractive in its own right from early spring to late fall.
I have it cascading over a rock wall, and when it blooms in late Sept. it always draws praise from passers-by. The cool weather of autumn makes the colours absolutely glow. I have a row of dark pink chrysanthemums behind it- they bloom together-a real knockout combination!
It is a great height (around 9 inches)- not too short like most groundcover sedums or tall and floppy like the big upright sedums.
The muted mauve/pink blooms contrast perfectly with the bluish
blush on the leaves. It offers a spectacular finale to the season in my garden (zone 3). Very easy to propogate from cuttings, but not at all agressive as are some others like sedum acre.

Sedum sieboldii's round spoke-y habit always draws attention in my garden. I have a rocky spot where sedum seems a natural, so in went several Vera Jamesons with their maroon stems and a sieboldii with its blue-green leaves with maroon edges (several other varieties whose names escape me followed me home and joined the crowd, too). This sieboldii is happy on the east side of a white pine, where it gets sun, but not a huge amount. Love its form!

An elegant combination of mauve blloms and grey-green foliage. Sedum has a delicate appearance, but is a hardy, drought tolerant perennial to enjoy year and year. Native to the high mountians of Japan.
Allow potting mix to dry slightly between waterings. Do not allow to stand in water. Needs bright light indoors and bright indirect light to full sun outdoors.
Makes for a great spreading ground cover, often starting new plants from fallen leaves or broken off stems.
Mine are in full bloom at this moment (early fall) and many people comment to the lovely petite flowers.
