'Morning Calm' Chinese Trumpetcreeper has huge open-faced flowers that are orange, apricot and yellow. Flowers are very attractive to hummingbirds. Slower growing and more woody, Campsis grandiflora 'Morning Calm' knows its place in the landscape better than the native form. The species is native to eastern and southeastern China. 'Morning Calm' was introduced by the JC Raulston Arboretum in Raleigh, NC in the mid 1980s.
