    Rare and dwarfest we've ever seen. Hallasan is fast becoming a favorite serrata around here, which is really tough to say with all the competition in this family. But, dwarf form, really! Native to the Hallasan National Park in South Korea, it's compact and spreading nature could rival your favorite ground cover. Richly pigmented blooms and dark green foliage are absolutely stunning.
