This year it looks like the western monarchs will be able to feast on some awesome native plant blooms in California. The heavy rains this state has been experiencing over the winter have been making up for the long drought. Sprouting of several species is already being seen in the Antelope Valley California Poppy Reserve, so their typical mid-March into Mid-April Poppy (Eschscholzia californica) bloom should be spectacular and just in time for the Western Monarch Migration.
Saddleback Butte State Park in California is actually experiencing an early bloom and expect to see some spectacular floral showings this year.
