I rather like pseudacorus. I had it for a while, but it's far too dry here for it to establish enough to become invasive. It lived 3-4 years as long as I was providing supplemental water, but declined and disappeared when that option was no longer viable. Some of the Louisiana iris actually lived a couple of seasons longer than the pseudacorus. I am currently growing some pseudatas, but they are being treated solely as container plants. I sometimes have issues with what plants are described as 'invasive'. A native plant can certainly take advantage of poor management or extended droughts or extended wet periods to aggressively dominate other native plants. For my part that is invasive whether the plant is a native one or not. With our extended drought here, the mesquite and opuntia have taken that opportunity and their establishment in greater numbers will be permanent at the expense of other native plants regardless of whether the weather changes back in favor of the other plants. That's invasive growth whether the plant doing it is native or not. Otherwise, the word 'invasive' is applied too broadly. Texas covers a lot of square miles. To say a plant is invasive in Texas is not sufficient. It's just not specific enough. A plant may be invasive in west Texas, but not in east Texas or vice versa. On the other hand, you seldom see non-natives like Bermuda grass or Johnson grass described as invasive. They both are considerably more opportunistic non-native plants than other plants that get the designation. Off the soapbox now!
