I took these pictures for Bonnie. They aren't iris....although I saw some good spots to put NOIDs.
My little boxwoods that top off at 5 feet and other trees that are supposed to top off at 16 feet max are posted. Of course, anything can be trimmed or bonsaied.
I also planted a number of larger evergreens - American and Green Giant Thujas that are supposed to stop somewhere around 40 - 50 feet; 3 spruce to 150 feet and a pile of Scotch Pine 50 - 60 feet. Those large ones will create a forest garden for trillium, Lady Slippers, Jack-in-the-Pulpit and the like. All of the big trees went on the northwest side of the house where the sun last shines in the winter anyway. As they increase in size, sun loving flowers will be moved or migrate themselves into the sun.
Chicagoland Boxwood. Has grown maybe 5 inches fluffier in 3 years and is 15? inches now. This one keeps its beautiful color all winter without that blah browning of many evergreens.
Abies Koreana Aurea - Dwarf Korean Fir - often sold as a Bonsai and can be quite expensive. I got mine on eBay for $13 delivered and it was very healthy! This tree should be about 8 feet high in 10 years and will top off at 16. I may move it closer to the house so I can see it from my massage studio window. Here is one on eBay so you can see better pictures.

An Emerald Arborvitae - supposed to get 20 - 25 feet high and 2.5 feet wide with 2 boxwoods. These are surrounded by a mulberry bush, a cherry and a plum tree that will be kept under 20 feet. The front of that garden is screaming for some Siberian iris that need to be separated.
My good neighbor's ugly stuff pile and chain link fence. The little boxwoods at the bottom will grow just high enough to cover this without stealing sunshine. I am going to prune these so they fill out more. The prunings will be stuck in the ground to start new plants.
A male and female holly, supposed to go to 12 feet next to a Blue Spruce that will get really tall unless it is pruned. The hollies come in a number of sizes, but can all be pruned. Zone checking is important with holly. Many wouldn't work in colder zones, but enough do. A male and female are needed for berries.

Dwarf Alberta Spruce - supposed to get 12' tall and 12' wide.
