I've had or have problems with almost everything you all have mentioned above. Cleome is another really bad reseeder, but I really do like it and usually end up letting one or two grow each year. Moning glories also have the reseeding problems. Been years since I've let any bloom and I still pull lots and lots each year. The low growing sedums I love more than I hate, so let many of them grow, but pull up many each year. Not too bad since they are so easy to pull. Had a blue globe thistle that I also got rid of because it reseeded all over and they were hard to pull unless you got them right away. Goldstrum rudbeckia has left my garden too because of the reseeding and also most asters because they reseed or get diseases. Talinum paniculatum. Same problem with reseeding. Gout weed, spreads too much.
