Ask the Expert: what is this plant? Hello. This orange plant has come up in my perennial garden. I don’t know what it is. I get plants from friends and stopped at a “free perennials, you dig” site one day this summer, and I’m not sure who gave me tis plant. The foliage looks like an iris but the flower looks like a columbine. It has just started flowering this past week. I live in NH. Thanks.
