Dwarf Conifers at demonstration garden 

There are over 20 varieties of dwarf conifers at Demonstration Garden. They are located near the south arbor. Plants nearest the arbor were installed in 2002. Likewise, years later the south entry was modified. This resulted in the expansion of the existing rose and conifer displays. Renovated in 2010 and 2011, many unique conifers now live here.  Flagstone was added to demonstrate ‘outcropping’. A large circular berm serves as home to spruce, cypress, juniper, arborvitae and pines of differing shapes and sizes. See detailed list below.
