I brought this jelly-bean sedum back from the US back in 2007.
At first I kept the plant in the shade house, the plant looked all green and lanky.
Then I moved it outside to get more sun. It turned to a dark chocolate color, and still looked lanky.
To improve the look of the plant, I trimmed off almost all the long growths and kept the plant in full sun. After several months, the plant has achieved this new look.
