My area is more dry and hot during late Spring to Summer, and Butterflies that make it to my garden seem to have a color preference rather than scent preference: It is fun to watch them as they make their specific choices
Eastern Swallowtail and Monarch Butterflies love my Asclepias currasavica:
With or without blooms this Monarch kept coming back to Asclepias currasavica
Eastern swallowtail seems to like to see yellow& red and bluish/purplish and white blooms:
On our yarrow
On our dwarf agapanthus
On our calamondin tree
On our Asclepias currasavica
Skipper butteflies loves our yellow lantana
This painted lady butterfly just loves anything pink:
On the Lewisia
On Crassula springtime
