Beware! These California superblooms are beautiful but treacherous

Tourists and travelers driving to visit California’s superblooms this year may see some striking vistas along the way — swaths of bright yellow, perhaps, covering formerly drab hillsides.

Before you ooh and aah, keep in mind: Some of that growth is invasive species that pose a treacherous threat. Experts say these plants can create stark and dramatic changes to the environment, altering soil chemistry and erasing native flora in some areas.
