Sometimes I wonder how known bad actor plants get into our wild areas. I guess I don't need to wonder that much. Here's photo from Sunday's grocery shopping trip to Sprouts market.
That was a sarcastic nice.
Actually Cal-IPC says, "“Sweet broom” (Cytisus spachiamus or Genista racemosa) is
not known to be invasive. However, because we lack information on its
potential for invading wildlands, we do not recommend it as a substitute
for other brooms." So it may not be as bad as the known invasive brooms, but why would we take the chance? Even if it's not invasive, it may hybridize with invasive brooms and make a big problem bigger. Blech.
