Pinus resinosa ‘Knee Knocker’
About Pinus resinosa ‘Knee Knocker’: This fluffy broom was knee high on a young red pine tree, a real “knee-knocker”, discovered near Marquette, Michigan. This cultivar is part of the Davisons’ Gitche Gumee Collection of the Lake Superior region. The broom grafts nicely and the lush dark green long needles of the grafted specimens almost have a tropical texture, but hardy to zone 3, as noted by Sam Pratt of the Conifer Kingdom/Rare Tree Nursery. Pinus resinosa ‘Knee Knocker’ is in the conifer collections of the Green Bay Botanical Garden in Green Bay, Wisconsin, and the Oregon Garden Arboretum in Silverton.
