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 Source: Xuân Diệu- Một khoảng trời thơ, Sở VHTT Nghĩa Bình, 1986.
