My first experience with this evening primrose species was in Pennsylvania, where it grew in our narrow driveway bed. I was always enamored of its pink flowers In late May and June. Up close, they are even more interesting, with their bright white plus-sign stigmas. The foliage is nothing to write home about - a bit scraggly, but at least it stays green. Even in PA, the plant wanted to scramble around by its roots, but in the marginal conditions provided by our driveway bed, it was just manageable.

Fast forward to Texas, and evening primrose is one of the main wildflowers growing along roadsides, sharing the stage with other Texas luminaries such as bluebonnets and Indian paintbrushes. So lovely! So well-adapted! Too well-adapted! Alas, in our new garden, pink evening primrose is without a doubt a weed. A lovely weed – but one that will conquer all if not battled vigorously.The photo below gives an impression of the effect when weeding efforts are only half-heartedly applied. Note they have invaded the lawn as well, making eradication next to impossible.
