Picture Description
A vibrant specimen of Euphorbia lactea ‘Variegata’ (Striped Form) displaying upright winged stems decorated with fine cream-colored stripes radiating across deep green succulent tissue. The evenly spaced variegation produces a striking zebra-like pattern, while the gently undulating margins are lined with paired reddish spines and tiny developing leaves. The symmetrical branching and vivid coloration highlight one of the most elegant ornamental forms of the Dragon Bone Euphorbia. Photographed at Green Desert Agritourism Park, this specimen demonstrates the remarkable diversity of variegation found within Euphorbia lactea.
Plant Description
Euphorbia lactea ‘Variegata’ (Striped Form) is an ornamental cultivar distinguished by its finely striped cream and green stems. Unlike heavily marbled variegated forms, this cultivar displays narrow, regularly spaced cream markings that extend across the winged ribs, giving the stems a distinctive zebra-like appearance. The striking contrast between the bright green tissue and delicate cream striping makes the plant attractive throughout the year.
Like the species, it develops upright candelabra-like branches with four winged angles and gently scalloped margins bearing paired spines. Because portions of the stem contain reduced chlorophyll, growth is generally slower than in the normal green form. Its refined variegation and strong architectural habit make it a highly desirable specimen for collectors and botanical displays.
Basic Information
Scientific Name: Euphorbia lactea ‘Variegata’ (Striped Form)
Author Citation: Based on Euphorbia lactea Haw.
Family: Euphorbiaceae
Genus: Euphorbia
Plant Type: Variegated succulent shrub
Origin: A cultivated variegated form of Euphorbia lactea, native to India and Sri Lanka.
Plant Overview
This striped form represents one of the many ornamental expressions of Euphorbia lactea. Instead of broad marbling, the stems exhibit fine cream bands that emphasize the natural ribbing of the plant. New shoots emerge bright green before gradually developing their characteristic striping.
Its upright branching habit, combined with subtle but striking variegation, creates a refined architectural specimen that complements both green and white forms of the species. It is especially admired by collectors who appreciate the diversity of variegation patterns within Euphorbia lactea.
