Adeniums, which all have poisonous sap, produce flowers in striking reds, pinks, and mauves; red-and-white bicolored flowers are fairly common. They are interesting caudiciform plants and make ideal container subjects. Known to occur in more arid regions, adeniums are sensitive to frost and waterlogged soils. The plants are usually deciduous during winter or the dry season. South African species of Adenium do well in warmer gardens and their rather handsome flowers make them an attractive addition to a garden.
