The Herb Twopence Fairy

Have you pennies? I have many:
Each round leaf of mine’s a penny,
Two and two along the stem—
Such a business, counting them!
(While I talk, and while you listen,
Notice how the green leaves glisten,
Also every flower-cup:
Don’t I keep them polished up?)

Have you one name? I have many:
“Wandering Sailor”, “Creeping Jenny”,
“Money-wort”, and of the rest
“Strings of Sovereigns” is the best,
(That’s my yellow flowers, you see.)
“Meadow Runagates” is me,
And “Herb Twopence”. Tell me which
Show I stray, and show I’m rich?
