Blue Sparkler Larch

Blue Sparkler is an upright, blue-needled selection of tamarack, the American larch (*Larix laricina*). Its dense, congested branches angle outward, and pale blue needles mature to gray-blue through the growing season. [The American Conifer Society’s record](https://conifersociety.org/conifers/larix-laricina-blue-sparkler) identifies it as a witch's-broom seedling selected in 1985 by University of Connecticut horticulturist Sidney Waxman. ## Size and seasonal form The Society reports about 3 feet tall and 30 inches wide after ten years, with annual growth of roughly 3–4 inches. That is a ten-year size reference rather than a fixed ultimate limit. Tamarack is deciduous: its needles yellow and drop in fall, then fresh foliage appears the following growing season. Use the compact, cool-colored form as a specimen or in a mixed conifer planting where its developing width has room. ## Site [USDA’s Tamarack plant guide](https://plants.usda.gov/DocumentLibrary/plantguide/pdf/pg_lala.pdf) reports the species in wet peatlands and moist upland soils and notes that seedlings need full light and constant moisture. These species-level conditions provide a useful starting point, while the selection's final size will depend on site and growing time. The exact Blue Sparkler record is *Larix laricina*, even though the selection is sometimes listed as Japanese larch. ## Maintenance Keep the root zone from drying for long periods, particularly while the tree establishes. Maintain enough clearance for the branches to expand and remove only dead or damaged growth; avoid routine shearing that would erase the selection's natural outline.
