Hoa cà phê(Xuân Diệu)
Hoa cà phê thơm lắm, em ơi Hoa cùng một điệu với hoa lài
Trắng ngà, trong ngọc, xinh mà sáng
Như miệng em cười đâu đây thôi
Hoa dạt dào thơm, mắt dạt dào Mỗi hoa như thể một vì sao
La đà mỗi nhánh hoa chi chít
Tất cả hoà hương: sâu, rộng, cao...
Em đến đây em, đặng bốn bề Ta cùng lạc giữa hoa cà phê
Cho sương ướt tóc, hương đầy áo
Cho trĩu hồn thơm, mới trở về
Buôn Ma Thuột, 12/02/1979
