need more info really...tall plants? Do you mean herbaceous perennials?
it depends on your soil and how warm it is, etc., but I grow several tall perennials. Veronicastrums, salvias uliginosa, guaranitica and even Amistad is tall. Acteas, heleniums, delphiniums, verbena bonariensis, some agastaches I grow are over 5' too. Cannas will soar. Consider Dieramas.....grass like mounds producing flower spikes as much as 6' high. Tall grasses like Calamagrostis, miscanthus, panicums, molinias and STIPA gigantea add movement as well as height. Foxgloves of course and I'm sure others will add to the list.
loads of mid height perennials...dahlias can be tall, middling or small.....like echinaceas, rudbeckias, asters, summer "chrysanthemums" like Broadway Lights, and even Astrantias can be quite tall to almost cushion like.
As I said, you will prob be inundated now with ideas from others here. But exciting to plan Minosgardener?
