    More Information

    Dahlia imperialis, also known as Tree Dahlia, is a species of dahlia native to Central America and Mexico. It grows up to 3 meters tall with purple/pink flowers that bloom in the summer. The dark green foliage looks similar to a tree’s leaves, giving it its common name.

    It is an ideal dahlia for a tropical border in the garden, or you can grow it in a large greenhouse or conservatory, where its chances of flowering are greatly increased. The appearance is quite unlike your usual dahlia with single drooping pink flowers and foliage on bamboo like stems. With some patience and care, Dahlia Imperialis can add a unique, eye-catching element to your garden!

    Planting Dahlia Imperialis

    Begin by planting these dahlia tubers in well-draining soil, in a sheltered spot in full sun or partial shade. Make sure the soil is rich in organic matter, like compost or aged manure, and keep it consistently moist. Planting multiple dahlia tuber clumps together helps to create a bushier plant faster than single planted ones would. Keep in mind that they may take up to three years before reaching their full size of 3 meters.

    As the plant matures, pinch off any dead blooms to encourage new growth. Its stems are sturdy, so there is usually no need to stake.

    With mild winters and mulching they can be left in the ground with some success over winter. The tubers are very large and it often easier to leave them. Fertilize in the early spring with a balanced fertilizer for best results.
