Horticulture Science
Transforming the built environment
Home / Biodiversity Initiatives / Horticulture Science
Horticulture takes a variety of forms, from public parks and roadside plantings to front yards and balcony flowerpots. No matter what the effort, think “Right plant. Right place.”
That is the grounding principle of Horticulture Science at CNPS. In California, native plant gardening is on the rise, as drought and the state’s conservation ethos drive the transformation of both public and private landscapes. But there are risks: The wrong plants in the wrong places can threaten rare plant populations in the wild, introduce disease, and harm local ecosystems. CNPS is working alongside partners to ensure the best available science supports our healthiest built landscapes, literally from the ground up.
As we face the emerging crises of climate change and extinction, plant genetics can provide helpful clues into how species are able to respond to changes in the environment and how they might survive.
