Despite the fact that the average gardener has absolutely no idea why any
plant is so named the way it is, I will tell you why.

Bottom line:

Type species for genus Sedum L. is Sedum acre L. and is a dwarf evergreen
perennial with connate kyphocarpic carpels.

Genus Hylotelephium H.Ohba (formerly Sedum section Telephium) are deciduous
perennials, usually with a tuberous rootstock, and with separate stipitate
(slender stalked) carpels.

It should be obvious that the growth form of Hylotelephium is very different
from that of typical Sedum.

Dissect the flowers and you will the differences between the two genera.
