Name: Susan Virginia (Zone 8a) God is the only thing that matters.
Is one plant all I need? How many plants is this, looks like a nice spread for a butterfly buffet.
Consider the lilies of the field, how they grow; they toil not, neither do they spin: And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these. Mat.6:28-29
One plant is a good start but one, you need quite a few as otherwise the butterfly larvae will strip them. Don't remember how many plants there are in the picture but it is a bunch.
