"strongylodon macrobotrys" is not frost-tolerant; it needs a minimum temperature of 15 °c (59 °f). it is prized in tropical and subtropical gardens for its showy flowers which are a highly unusual colour, unlike that of almost any other plant. it is usually grown over a pergola or other tall support to display the spectacular cascading flower trusses which are produced generously once the vine is mature (after 2 years or more, depending on pruning regime). curiously, on a large plant, the pale-coloured blooms can be difficult to see in strong sunlight and could be overlooked if not for the fallen blooms below the vine. fallen blooms change color as they dry out, from mint green to blue-green to purple.
