Dianella tasmanica

<strong><a href="https://en.promessedefleurs.eu/perennials/perennials-by-variety/dianella.html" target="_blank" rel="noopener">Dianella</a> are rhizomatous perennials mainly native to Australia</strong>, forming clumps of long, narrow leaves reminiscent of Phormium foliage.<strong> The leaves come in various shades depending on the varieties</strong>: they can be green, blue-tinged, chocolate brown, or variegated with white. Dianella is also very decorative due to its flowering in light, airy panicles, bearing numerous small<strong> star-shaped blue flowers,</strong> with yellow stamens. These flowers then give way to stunning <strong>metallic blue berries</strong>. <strong>Dianella is one of the few perennials that produce very decorative berries.</strong> <strong>Dianella are not very hardy</strong>: they tolerate temperatures between -5 and -8 °C, and even down to -12 °C in a sheltered position and in perfectly drained soil. They can be planted in the ground in the Mediterranean basin and Atlantic coastal regions, where the risk of frost is low, but in the northern half of France, it is better to grow them in pots so they can be brought indoors for the winter. They are <strong>particularly suited to seaside gardens</strong> as they tolerate salt spray well. In the garden, they will easily find their place in a Mediterranean, exotic, or graphic style garden. <strong>Discover in this guide all our tips for successfully cultivating them, whether in the ground or in pots!</strong>
