 Horticulturists have hybridised the kurrajong with related "Brachychiton" species, including the Queensland bottle tree ("B. rupestris") and Illawarra flame tree ("B. acerifolius") to produce new garden ornamentals.The specific name "Brachychiton populneus" pertains to a perceived similarity to genus "Populus", the poplars.Sometimes "B. populneus" is also known by the names "lacebark kurrajong" and "bottle tree" (USA).
