The Plant Pun...Revised for Fairness

This may flop, but here goes...Can you figure out this plant pun?

EDITED ON 9/27 AT 6:39 PM....I THINK THE OPTIONS NEED TO BE NARROWED (although Thing's idea was clever). FIRST, THE PUN REPRESENTS THE NAME OF A FAMOUS PERSON, BUT IF YOU ARE UNDER 40 SOMETHING, YOU MAY NEVER HAVE HEARD OF HIM.

HINT: FOLK SINGER...ACOUSTIC GUITAR...BEARD (or was it a goatee?)


.....I told you this might flop.

REVISED AGAIN AT 8:37 PM ON 9/27... HINT: "LITTLE BITTY TEAR"
