Littleleaf Milkpea: A Delicate Native Gem for Your Garden

Meet the littleleaf milkpea (Galactia microphylla), a charming native perennial that might just become your new favorite ground cover. This delicate member of the pea family brings subtle beauty and ecological value to gardens across the southeastern United States, proving that sometimes the most understated plants make the biggest impact.

What Makes Littleleaf Milkpea Special?

Don’t let the name fool you – while it’s called milkpea, this native beauty is actually a legume that produces lovely small flowers rather than the white sap you might expect. As a perennial forb, littleleaf milkpea lacks woody stems but returns year after year, making it a reliable addition to your native plant collection.

You might also see it listed under its botanical synonyms Galactia floridana var. microphylla or Galactia minor in older gardening references.
