Dahlia is a small genus of herbaceous to evergreen perennials with tuberous storage roots. They are native from Mexico to South America. Most species have showy, bright colored flowers in profusion from late spring to autumn. All are easily grown in any rich, well drained soil in a sunny spot in the garden. In autumn tuberous roots should be lifted after the first freezing nights have touched the leaves and stored rather dry in a cool, yet frostfree spot at a minium of some 10°C. Replant in spring as soon as the last strong frost are over.
Sow seeds flat in any humus-rich, well drained substrate at some 20°C throught the year. Keep young plants in pots under frostfree conditions and in a sunny spot for one to two years before planting out by the end of spring.

Dahlia imperialis (Bell Tree Dahlia)

Dahlia imperialis (Bell Tree Dahlia)

250 (350)cm, Bell Tree Dahlia is only for its size one of the showiest species in the genus. Dahlia imperialis is a fast growing herbaceous perennial species native of mountaineous regions from southern Mexico to northern Colombia. It makes annual tall shoots from a strong tuberous rootstock, and terminal lose clusters of large intense rose flowers from late autumn to early spring. Easily grown in any rich, well drained soil in a sunny to partially shaded spot. With a good winter protection (e.g. a thick dry mulch layer) the rootstock is reliably winterhardy. However due to its late flowering season it is best grown in a cool wintergarden or greenhouse under frostfree conditions. Seeds are from a motherstock originally collected near Puerto Caté, Chiapas province, Mexico at some 1650m. Flowers in this population are more open and of a richer rose color in comparison to the usually more closed, bell-shaped and pale rose flowers of plants available in the garden trade. VI-VIII.
