The Hall's Hardy Almond Tree features a medium sized hard-shelled almond, with a sweet to slightly bitter kernel. Roasting and salting will remove bitterness. The tree has beautiful, profuse pink blooms and are sometimes sold just for its beauty. Hall's Hardy Almond is a heavy bearer, and very cold hardy. It's also semi-self-fertile, but works better with a pollinizer. This particular almond tree requires only 800 chill hours, and ripens in October.
