Apex Crevice Garden
Wanting to create a unique destination garden at the site of a new recreational park, Arvada Parks and Recreation District decided to build a crevice garden. It was designed and built by Kenton Seth, with help from Paul Spriggs, a student of the current Czech master of crevice gardening, Zdenek Zvolanek.
Built with 60 tons of Dakota sandstone from southern Colorado, 14 tons of sand, and another 20 tons of other gravels and materials, it is one of the largest crevice gardens in the world, if not the largest. Envisioned as the first public xeric crevice garden in the traditional Czech style, it contains an estimated 200 species of xeric plants which can live with fortnightly or less watering. It is almost exclusively focused on buns and cushions to introduce the public to this form of vegetation, amongst some dramatic accent plants and manzanitas. The five separate beds provided an opportunity to try different soil mixes; the bottom layer is always the native clay and the top is always a dressing of gravels, but the middle layers vary, including pure sand, sand and expanded shale over loam, sand and gravel, sand and compost, and sand over a little compost.
Arvada Parks and Recreation District owns and administers the site, but the Rocky Mountain Chapter of NARGS is considering adopting the garden to maintain and use for outreach.
