Sester’s Dwarf Colorado Blue Spruce retains the symmetrical growth habit and deep blue color of the species in a much reduced size. The pyramidal shaped tree at maturity will be 6’ – 8’ tall and 3’ – 5’ wide. Hardy outdoors in the Chicago area, specimens used indoors for Holiday displays should be kept in a cool sunny location after the exhibit is closed until the outdoor temperatures are reliably above 25 degrees Fahrenheit.  Plant in a sunny location that does not have standing water after a rain storm (well drained). Great tree for under power lines or for gardeners with small yards.
