The bursary, from the Landscape Institute and the Stephen Lawrence Charitable Trust, helped Perry, aged 40, into Kingston University and Mistry, aged 19, into Leeds Metropolitan University.
The institute explained that it started up the fund to encourage people from different backgrounds to become landscape architects.
President elect Sue Illman said: "We want to make landscape architecture a career that more people think about when planning their future."
Doreen Lawrence, director of the trust named after her son, Stephen, who was murdered in 1993, said the charity was delighted to work with the institute.
