I've been spending some time doing lots of research on trees, which is an area I'm less familiar with, because we're about to lose two very special trees. The tree cutters were supposed to come this week but the weather has kept them away.
We'll be taking out the rest of the cedar that was badly damaged (and threatening to eat our house) during a late winter snowstorm as well as the giant birch that is sickly and has needed to be removed for years. I'm especially upset about losing the latter and I'll be honest and tell you I might even shed a tear over that one.
I have a personal goal to plant a new tree somewhere on our property every time we take one out. Part of the beauty of our property is the hundreds of mature trees and I want to make sure that future owners will be able to enjoy them as well.
One tree I'm very interested in and actively trying to find is a Venus dogwood. I first read about this tree on Deborah Silver's blog a few years ago and when I read a mention of it elsewhere the other day it sparked a mental note I had saved that this was a tree to look into should I ever have a place to put one.
Well guess what Venus, a hybrid developed by Dr. Elwin Orton at Rutgers University, has going for it? No disease issues. Huge flowers (up to 4 inches, they claim). Bloom that lasts for maybe as much as four weeks (at least it does for Deborah who lives and gardens in Detroit). Fall color. Fast growing. Pretty bark. Twenty feet wide and tall at maturity. What's not to love? You can see why Deborah calls it, "the most spectacular white flowering tree on the planet." High praise.

We are having the birch stump ground out so we'll be able to replant in almost the same space. It's a special spot—the main focal point in the back yard—and we've enjoyed having a large three there so we're hoping to replace that with something prominent. I'm not sure what that will be yet. I'd love to plant an American beech (Fagus grandifolia) there because I love the other beeches growing on our property and we are in one of the few places in Wisconsin where they will thrive. But beeches are notoriously difficult to propagate in a nursery situation so it's very difficult to find one of any size.
We're going to wait to decide if we need an evergreen for screening purposes where the cedar will be removed. If we do, it won't be another cedar. The deer adore cedar and there isn't a cedar tree in our neighborhood (which happens to be called Cedar Beach) that has foliage below 7 feet. This is fine for mature cedars because they flourish above the deer-eating line, but it is impossible to grown them big enough to get to that point without a deer attack. Deer can destroy a cedar that's 10 feet or less in one night.
If we don't need the screening, I think this might be an opportunity for a small specimen tree. The location is just out the living room window so it has to be something special.
First of all, I love dogwoods. Most have a lovely layered branching habit that to me is the perfect combination of found-in-nature casual rambling and strict Japanese-style pruning (if such a combination is possible). Secondly, some, including Cornus kousa and Cornus florida have beautiful four-petaled flowers. Unfortunately they are also prone to a disease called anthracnose, which eventually kills the tree.

There are questions with hardiness. It is listed as hardy to zone 6 in some places and zone 5 in others. We are technically considered zone 5b ever since the USDA updated the zone map last year, but I'm wary of that qualification. It only takes one bad winter to cause major damage. Deborah says she has planted 80 of them in the last several years and hasn't lost one, but Detroit is definitely a warmer zone than us.
So if I go down this road and can find a Venus dogwood, it will be with a bit of trepidation and finger crossing. Sometimes that's road that a gardener can't help but take.
