About Botanique Designers
A landscape practice founded on plant science.
The Story
Botanique Designers started with trees — specifically, with the work of identifying and labelling them. At learning institutions across Kenya, Widson Ambaisi walked campus grounds, keyed out species using botanical references, and installed labels showing each tree's scientific name, common name, family, and origin. That work — applied plant taxonomy — became the foundation of everything that followed.
The name "Botanique" comes directly from this botanical practice. It reflects a belief that knowing a plant at the species level — its growth habits, its soil preferences, its altitude range, its water needs — is the starting point for any landscape decision. Not aesthetics first. Science first.
Today the practice covers landscape design, landscape architecture, garden implementation, and ongoing maintenance. Widson leads design and plant science. Martine Lotom, a landscape architect from JKUAT, leads architectural-scale planning and site supervision. Together they deliver projects across Kenya, Tanzania, Uganda, Rwanda, and Somalia.
