Tree Dahlia
Notes

Popular tall perennial  shrub. Large pink flowers  grow on long bamboo like canes. Propagation can be done by separating sections of the cane and planting horizontally in the soil. Tree Dahlias need to be protected from frost and strong winds. The long canes can be staked as they are brittle.  Tolerates a variety of soil but it must be well drained.
