UCLA alumnus Morton La Kretz has donated $1 million to the university's seven-acre Mildred E. Mathias Botanical Garden.
The money will be used to create a new entrance to the garden, which was created in 1929 and is now used as an outdoor lab for some school courses, according to the university.
"This is a hidden gem on the UCLA campus," La Kretz said in a statement. "I'm delighted to be able to lend my support to such an important UCLA asset."
The garden hosts thousands of plant species, in addition to salamanders, lizards and koi, according to the university.
"The garden is really special," said director Philip Rundel in a statement. "When I give tours, everybody is amazed by the beauty of the garden, particularly if they are seeing it for the first time. They can't believe they are in West L.A."
