Magic lilies are the bane of my existence here in Hermann. I do not exaggerate when I say I have dug out 12 buckets ( 5 gallon buckets!) of the things. I give them away. We also composted many of them.
This is now my second year of digging the MF things. At some point I want to, ya know, plant my own stuff and not have to suffer the crap previous owners put in the ground.
The rampant non- blooming daylily. The ubiquitous non blooming Siberian iris. There is way too much of this junk.
