FlytrapCare Carnivorous Plant Forums

I am hoping to come up with a planting aesthetic that works for our backyard to make my current array of black plastic concrete tubs look better in a more visible area so I can enjoy seeing my plants all of the time while keeping my wonderful spouse happy. I am looking at deep large vases like are used to display plastic shrubs inside of houses as they can be had for a pretty reasonable price second hand. They are generally glazed ceramic and up to about 24 inches deep. Is this too deep to work well and will water get too stagnant in the bottom of the vase? I will probably give it a go as they are affordable and I have plants that I can try with and just replant if they aren't happy, but I figured someone on here might have direct experience. I would imagine pitchers probably have very deep root systems in the wild, but do not know for sure. I am specifically thinking about S. flava, alata, or leucophylla, or a mix of all of them. Cheers and Happy New Year!
