Perennial, 2-6 weeks at 15-18°C, sow April-June. Sedum is easily planted. For shorter varieties, simply laying the sedum seed on the ground where you want it to grow is normally enough to get the sedum plant started there. They will send out roots from wherever the stem is touching the ground and root itself. If you would like to further ensure that the plant will start there, you can add a very thin covering of soil over the plant. Grow inside anytime for indoor plant use.
