Christmas Island is covered with lush green vegetation and is notable for its flora and fauna. It is home to around 411 plant species, of which 213 are native and about 18 endemic. This stamp issue depicts four common species of flowering shrub native to the island: Colubrina pedunculata, Abutilon listeri, Urena lobata var. sinuata and Indigofera hirsuta.
Artist Deirdre Bean has detailed the shape and texture of each shrub's foliage and flower, as well as the relationship between the leaf and bloom. The approach is from the long tradition of botanical art. This is the first stamp issue for which Deirdre has been commissioned.
