Dianella Plant Description
Featuring leaves that grow up to one meter long, Dianella is an underground rhizome. It flowers in spring to produce blue flowers with three sepals and petals each. The prominent stems are yellow and leaves range in color from blue-green to pale-green.
The elongated or spherical, shiny berries can grow up to 5cm in diameter. They feature shiny black seeds and spongy flesh. Nearly all Dianellas are perennials; they feature gass-like leaves and develop tufts. They also have jointed stems with opposite leaves and terminal flowers.
The plant genus was named after the mythical sylvan hunting goddess, 'diminutive of Diana.'
Dianella plants can be propagated using rhizomes or through division. They grow in the USDA hardiness zones 8, 9 and 10. The plants are tolerant to drought, frost and salt.
The evergreen plants thrive in well-drained soils and require medium water to grow. Other growth requirements include partly shade to full sun, moderate fertilizer and temperatures of 100 F to 200 F.
