14.5-15.5% AA. Grows well in dry, hot climates. Vigorous but susceptible to mildew diseases. Columbus is a high-alpha hop that provides a neutral bitterness and an excellent aroma. The flavor and aroma are very pungent, so it is often used for late-addition hopping or dry-hopping. Great in IPA's. Flavor is slightly floral with some citrus notes. Also goes by the names Tomahawk, Zeus, and CTZ. Rhizomes should be planted immediately for best results. If your area is still experiencing frost then you can plant them in a planter indoors until it is safe to transplant outside. The first years crop will generally be smaller than subsequent years. Since these are live plants, we cannot guarantee they will grow, so we recommend buying two of each type to help insure their success. Since the rhizomes are presale items, we ask that you do not place other items on your rhizome presale order. Any additional items placed on rhizome presale orders will be split into their own order, and subject to additional shipping fees.
