The appearance is quite unlike your usual dahlia with single drooping pink flowers and foliage on bamboo like stems.

Begin by planting Tree 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 Tree 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.

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, Tree Dahlia tubers 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.
