Although native trees such as coast live oak and California buckeye are present, most of the park bordering Lake Merritt has been landscaped with plants from around the world. As early as 1910, City Park Commissioners recognized Oakland as a city of immigrants, and felt that "visitors to the park would want to see plants from their native lands". This theme of diversity in the park landscape has continued with landscape renovations. The lake's iconic plant is the New Zealand tea tree ("Leptospermum" sp.), which grows with picturesque gnarled branches along the water's edge.
