Mass planting of a single color for butterflies?
I'm starting to realize what a difference it makes to have a large area of a single color, single plant, to attract butterflies. I'd read this before several times but it took awhile to sink in I guess.
I've noticed as my verbena bonariensis has spread into a bigger patch every year that it has become more attractive. The first year I had it, I had four plants, and the butterflies completely ignored it. I was disappointed. But as the patch grows, the butterflies get thicker every year.
I'm almost sure that's why my Scarlet Flame zinnias were a butterfly magnet this summer. Not because it had better nectar than my other scattered zinnias, or that it was a special color, but because I had a big patch of a SINGLE color to draw them in.
I don't think it's just that I have more butterflies every year. My pentas and lantana didn't get much action this summer but I suspect if I had a BIG patch of those instead of just a few, the butterflies would be flocking to them.
I'm going to try to keep this in mind this year when I order seeds. Instead of trying several different things, I want to try to plan a couple more big masses of color.
What do you think? What would you plant a lot of? What do you already have a lot of?
