Wildlife

Said to attract hummingbirds.

Larval host of the polka dot wasp moth (Syntomeida epilais), but there is a question whether or not that's a native moth as that is the moth that defoliates oleander and desert rose plants.

Skipper butterflies visit the flowers.

Said to attract butterflies.
