This is in Texas?

Yes

If you do a web search for the topic of planting near pools a recurring theme will be the need to choose kinds like bananas and palms that don't produce lots of little bits of stuff that clog filter intakes. Of course, if you get another killer winter anytime soon subtropical types like these will fail. And it's not unusual for eye opening winters to come in clusters. So what you probably need is something filtered for big parts + cold hardy. What grows natively around where you are, wherever there is any natural vegetation still present? Maybe some kind of tall growing yucca, perhaps?

It may not pass the tiny litter test, but Texas Mountain laurel, Sophora secundiflorum will give you the same size and form with grape Kool aid smelling flowers in a Texas native. The Japanese Blueberry gets complaints about the litter so it can't be worse?
