A small tree, sparsely branched, the branches elongated and elegantly twisted, hence ‘snake’. The foliage is a rich blue-grey. Hatch suggests it is initially upright, but Auders & Spicer say it will only form an upright tree when staked, otherwise it will slither along the ground. To 2.5 x 0.3 m in ten years when staked. Discovered by Piet Vergeldt of the Netherlands in 1962. (Auders & Spicer 2012; Hatch 2018–2020).
