Following the completion of the acclaimed Tari, Topeng and Wayang series, Dato' Yusof Ghani initiated the Hijau series, marking a significant transition towards subject matter drawn from the natural world. The series embodies the artist's reflections on the beauty of flora and fauna while expressing concern over the gradual encroachment of development upon the environment. These works were later presented in a solo exhibition at Galeri Petronas in 2002. Hijau Series 'Pokok Beringin' is rendered in the language of Abstract Expressionism, characterised by energetic brushstrokes in vibrant hues of yellow, red, green, blue, and black. Through vibrant chromatic harmonies that convey the ephemeral qualities of light and air, Dato' Yusof reimagines the landscape as an emotionally charged and expressive realm. Dato' Yusof Ghani started out doing Art-related jobs for 10 years without formal education. He was artist-illustrator at the Agriculture Ministry (1967), instructor in the Fisheries Institute, Penang (1971) and a graphic artist at Radio-Television Malaysia (1977). Then he got a scholarship to study for his BFA at the George Mason University in the United States (1981), and MFA at the Catholic University in Washington, USA (1983). On his return, he lectured at the Universiti ITM with the rank of Associate Professor, but unleashed some of the most memorable art series: Tari, Topeng, Wayang, Hijau, Segerak, Biring, Wajah, Ombak, Kuda and Cenderawasih. He organised the Shah Alam Biennale involving artists from 15 countries in 2016. Yusof Ghani made his London foray with an exhibition, Segerak VI - Transcendent Figures, at the Asia House in early April 2017. Henry Butcher Art Auctioneers with partners Galeri Prima and Pinkguy Gallery organised Segerak VIII: Utopia, the final edition of Segerak series, in August 2019. The exhibition received good responses. In December 2021, a painting from the Tari series painted by Dato' Yusof Ghani realised RM 403,200 at Henry Butcher Art Auction.
