Definition, Please
OK, so my guess is that the garden in question is growing flowers or vegetables, and the butterflies are merely a nice fringe benefit.
But, I like the imagery — and I give the listing agent (Edina Realty’s Pam Bandy) credit for creativity!
“Butterfly garden” was the term the sellers used for this flower bed. The flowers they planted were chosen specifically to attract butterflies. Perhaps an early version of today’s “pollinator gardens.”
