Congea and Sempervivum, are which type of items?
Sempervivum Sempervivum (Brit. , U.S. sem-per-VEE-vum) is a genus of about 40 species of flowering plants in the Crassulaceae family, commonly known as houseleeks. Other common names include liveforever (the source of the taxonomical designation "Sempervivum", literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offsets, and several species are valued in cultivation as groundcover for dry, sunny locations.
Arem-arem Arem-arem is an Indonesian Javanese snack made of compressed rice cake in the form of a cylinder wrapped inside a banana leaf, filled with diced vegetables, "tempeh" or "oncom", sometimes also filled with minced meat or "abon" (beef floss), and eaten as snack. Arem-arem is often described as a smaller size "lontong" snack with fillings, thus sometimes also called lontong isi (lit. "filled lontong").
