Atco goyo pine is one of several short-needled, naturally sculptural selections of Japanese white pine that were selected for use in Bonsai long ago. This conifer is an excellent choice for container culture or in-ground Niwaki sculpting. Be aware that plants allowed to grow "free range" will develop very long terminal shoots and become very lank and open.
Pinus parviflora 'Atco' is a short-needled, dwarf, upright selection of Japanese white pine. As already mentioned, this plant will look it's best when terminal candles are removed in the spring, allowing fully clothed shoots to develop. Plants will look best when these candles are shorted to 2-3 inches (5 - 7.5 cm) long each spring.
This cultivar is most-often seen listed under the name, Pinus parviflora 'Atco goyo.' Be aware that the use of "goyo" in this species is thought to be redundant and is therefor not used in the cultivar name. However it's perfectly acceptable to include it in the common name.
