Abies lasiocarpa 'Logan Pass' / Logan Pass Alpine fir
Abies lasiocarpa 'Logan Pass' is a witch's broom selection of Alpine fir. This plant is a true miniature, growing only about .5 inch (1cm) annually. Over time, it becomes a tight, round ball of short, gray-green needles and prominent buds. After ten years the plant will only be 6 - 8 inches (15 - 20 cm) around.
Discovered by Günter Horstmann around 1976 on Logan Pass in Glacier National Park, Montana
This is a perfect selection for use in troughs and rock gardens as it will likely never outgrow its place in the garden.
As with many tight-growing witch's brooms, chances for the plant's long-term survival can be strengthened through a yearly cleaning out of dead needles and twigs. Doing so will diminish the risk of fungal diseases and suffocation during hot weather.
