This black spruce broom Picea mariana ‘Sand River’ was discovered while maneuvering through a bog to harvest Picea mariana ‘MinneHaHa’! This broom had numerous small cones. Seeds from the broom cones were germinated and we saved the seedlings that exhibited a miniature growth rate. The broom scions also grafted well! One of the ‘Sand River’ specimens is on display at the beautiful Oregon Garden arboretum in Silverton.
