Originally found in the San Sabastian region of northern Bohemia,in The Czech Republic, along with many other witches brooms, it was given a number 24, but that has since been dropped and the name 'Xenie' given. The plant is a natural hybrid of Pinus mugo and Pinus uncinata, thus ssp. uncinata. The growth is less than 3/4" per year, so is considered a miniature conifer, and will make a tight miniature flat bun over time. Rare.
