Please help me with identification of this Sedum. It grows wild but in the urbanized area. It looks like Sedum purpureum but the flowers are yellow.
I'm inclined to think, based on the leaf shape, that it's not a Sedum, but the flowers say otherwise. Try Sedum hispanicum (yellow form) or Sedum aizoon (aka Sedum maximowiczii). Aeoniums have very similar flowers, but the stems on that are all wrong for Aeonium.
Its no longer a Sedum. Its Aizopsis aizoon. It is not a native to North America. It is an escape from cultivation. It looks nothing like Sedum (now Hylotelephium) purpureum, other than being succulent and Crassulaceous. BTW, there is no yellow form of Sedum hispanicum. That is a moss-like species with white flowers and glaucous terete leaves and looks nothing like the species in question. Aeonium and all the other Sempervivoideae have flowers with six or more parts in a whorl and are usually rosulate.
Thank you very much! It does look like Sedum aizoon. I checked the origin of this species and it is Siberia. Is it a common species anywhere in North America?
