With many garden worthy species Brachychiton are often seen as a tall growing tree to over 30m. Although this is true of some of the species, many of the new cultivars and hybrids are much smaller growing than this.
Many of the recently released varieties will reach between 4 and 6m over 20 years, others up to 10m. The height will depend on the particular hybrid as well as the growing conditions. Some will grow a lot larger in warmer sub tropical climates than they will in the temperate zones.
