Snapdragons – Antirrhinum majus – are not native to this area but they are a host plant for the buckeye butterfly. I haven’t been able to locate a source for any host plants for this butterfly that are native. Mine have been blooming for a little while now. They start blooming pretty early in the summer and sometimes keep blooming for a long time. I started some new plants from seed this year too and I am hoping that they will bloom later this summer.
Once – I think 2 years ago I actually found a buckeye caterpillar on my plants. If there have been more I missed them. Now don’t quote me on this, I’m a bit rusty with some of my butterfly knowledge – but I believe buckeyes are partial migrators and don’t get up here for a while usually, at least not in large numbers.
My favorite snapdragon flowers are the bright, nearly solid yellow ones and the read dark red ones:
