Another garden designed specifically to highlight the Winter season is the Macadam Winter Garden in Tukwila. It is a relatively new garden planted in 2007. We have been visiting the past couple of years and it has really started to come of age. It is not large. The highlights are the shrubs and trees along with a small stream lined with large grasses. Don't miss the beautiful Amelanchier. witch hazels, the birches and grasses. It can be a little hard to find but don't miss it.
