Oh - Ok, the first set of butterfly photos is from last year. Didn't catch that.
first off, I'll send you a lutea . . . it's a weed, and the flowers are small, but it's great butterfly feed and if you ever get into hybridizing, it's hardy and sets fruit easily, so it's a good one.
Second, they will eat almost any passiflora . . . but the nice thing about having lots of lutea or incarnata or caerulea (all weeds) is that you can move the cats there and still have the butterflies. Give me another couple of weeks and I'll send you whatever you want of those 3 cuz they are growing all over the back 40 . . . . and I will owe you forever for that song . . . .
