What was blooming at Junipero Serra?

Mexican Schools were not uncommon in Southern California.  These were schools that were established as segregated schools for Mexicans, not schools that eventually had an almost exclusive Mexican population because the families coming to live in the area all shared Mexican heritage.
To date we mostly have images that were taken at Junipero Serra school.

This seems to be from some school program in the last 1920s.  I'm betting it was a spring program because of the flowers and bees.

Not sure what the fellow in the far right is supposed to be representing.  I'm pretty sure he wishes he were wearing a different costume, or perhaps no costume at all.
