The Sievert Garden - Sunday, July 26
Waukesha, WI
About
The gardens on this one-acre property are largely the life’s work of one man, the owner, who designed, planted and built what you see today.
The property is predominantly a symphony of shade gardens with perennials selected mainly for their foliage, including 800 hostas. A celebrated feature is the abundance of local mosses used on flat ground, on mounds, in over 300 containers, and over 700 rocks. There is a water garden with three separate parts, a Japanese-style garden, a cactus and succulent garden, a sunken garden, a hillside garden, a stumpery, and a Williamsburg-inspired formal garden.
Five thousand paving bricks and 2,000 cobblestones were salvaged and used blend in with nearby wooded areas. The property has most recently been featured in the book, Garden to the Max: Joyful, Visionary, Maximalist Design by Teresa Woodard and Bob Stefko, and in articles in the Summer issue of Midwest Living Magazine, and the July 16, 2025, edition of the New York Times.
This garden's estimated size is 1 acre.
This Garden Host reports the following Terrain Notes about the garden: There are many steps in the gardens, most with railings. The paths and stairs are composed of bark mulch, antique bricks and cobblestones which can be uneven. Because the property was formed by a glacier, it is steep in places.
