Purple Porterweed

Stachytarpheta frantzii

Deep velvety purple blooms are produced continuously from spring to fall on this upright to spreading perennial. The Purple Porterweed is a medium sized variety becoming fairly dense as it matures.

Porterweeds are likely the number one favorite nectar plant for butterfly gardeners and surely for the butterflies themselves. I would be surprised to find a plant that produces a more continuous supply of nectar rich flowers from summer to frost, even most Lantana has to catch its breath from time to time during the heat of summer. This is one of the few plants that you will find consistently at nearly every butterfly conservatory. In zone 8B we find that the larger growing Porterweeds, like Lavender, Coral, and Purple, may return from the roots in late spring if well mulched. In zone 10 it is likely to be a reliable perennial if not evergreen. Porterweed is known to reseed particularly in mild winter climates.
