Thank you, GW members, for providing such an enjoyable forum! I'm new here, am an amateur veg and flower gardener, and appreciate the vast body of knowledge this forum makes available.

Now, may I please tap that hivemind knowledge? I went a little overboard with ordering seeds this year (sound familiar?) and will have rafts of flowers that are winter-sown and also under lights in flats.

Many are new to me; most are perennials. In contemplating them all and considering height, color, type of foliage, light needs....my head started to spin. Which of my flowers would make the prettiest pairings (or triplet combos?)

My situation: I have 9 3'-by3' raised boxes in my front yard. Each one has a dwarf fruit tree, leaving plenty of full-sun area for flowers. I also have sunny spots in the backyard that could harbor a flowerbed or two. May I ask, how would you combine the following flowers? I would be very grateful for your ideas! I have some, but I enjoy learning from others more experienced than me. Thank you in advance for any insights!
