Hops need at least 6-8 hours of sun a day, so the South facing side of your home or an exposed site is a good location. Hop vines (called bines) can grow to over 25 feet and weigh over 20 pounds, so vertical space for a trellis is important as well.
Often observed flicking its tongue, snakes use their forked tongue to smell the air. Snakes are ectotherms, meaning they must regulate their body temperature externally by sunning themselves or retreating to cool, shaded areas. Snakes hibernate during the winter. Snakes must shed their skin three to six times per year.
A snake may appear threatening when it flicks its tongue out, but it's simply trying to get a better sense of its surroundings by tasting the air. To compensate for their poor eyesight and limited hearing, most snakes have an excellent sense of smell. Although snakes have nostrils, they also use their tongues to pick up the scent of nearby prey or predators. When a snake flicks its tongue, it collects odors that are present in miniscule moisture particles floating through the air. The snake darts the tongue into its Jacobson's organ, which is located inside the roof of the snake's mouth.
