Many blossoms and trees are mentioned in
The Tale of Genji. For example:
"The hills were high in the southeast quarter, where spring-blossoming trees and bushes were planted in large numbers. The lake was most ingeniously designed. Among the plantings in the forward parts of the garden were cinquefoil pines, maples, cherries, wisteria, yamabuki, and rock azalea, most of them trees and shrubs whose season was spring. Touches of autumn too were scattered through the groves."
