Two years ago an area in our front yard was invaded by the beautiful mexican primrose, here in Long Beach, CA. The flowers are beautiful - then die out about this time of year, leaving rhyzomes for next year. I let them grow, but now that they're dying, I'm pulling out the dead foliage and impressed by the sheer amount of material involved!
In spite of the flowers in season, I'm wondering if I should try to eliminate this stuff, and if so how to go about it. Or, should I just mix in a little extra topsoil and nutrients, go ahead and plant the area with some ground-covering perennials, and let things go until the primrose's return next spring?
Any advice, war stories, and the like?
Thanks.
