This painting, Orange Daylily , is a work by Zhang Da-Qian under heavy influence of style and poem of Li Chan, one of the eight eccentrics of Yangzhou. Li's poem was used as the inscription of the painting. From the style of the artist's signature and the three seals used, one can roughly estimate the completion period to be around the 1930s. In the painting, the flower slanted upwards from the bottom left corner. Using green ink and swift strokes, long leaves were depicted with grace. At the other end, orange and red were used in boneless style to depict the budding daylilies. Each flower has its own form. The petals were depicted with 3-dimensional and semi-transparent effects. An ink-saturated dot was used for the stamen, which instantly enlivened the painting. One can see the exceptional skills used in the painting. Details were meticulously drawn with gongbi technique and broad brush was used for boneless technique.

Daylily carried the meaning of "carefree spirit" in ancient China and was also commonly referred to as a "mother", which could be traced to a poem by Meng Jiao of Tang Dynasty. To express his gratitude to his own mother, daylilies became his common subject of flower depiction. Aside from this painting, another work of similar subject, Daylily and Butterfly , completed by later 1930s, was kept in the Chengdu Museum. Both were copies of Dafeng Tang's Daylily and Butterfly from an anonymous artist of the Yuan Dynasty. Seal and Clerical Script could be suggested from the lines of bamboo and daylily. This was suggested to be under the influence of Zhao Meng-Fu, who promoted the concept of drawing with calligraphic script. Similar painting Daylily (1965) was displayed at the "Silhouette of a Great Master: A Retrospective of Chang Dai-Chien's Art on the 120th Anniversary of His Birth" at the National Palace Museum of Taipei. This more recent painting was depicted with a combination of boneless colouring of Chen Chun and Li Chan and calligraphic script of Yuan artists. By comparing the three paintings, one could observe Zhang Da-Qian's mastery of painting and his love for his mother.
