A rhizome is a piece of a hop plant that will sprout roots when planted, and it's what you will need to purchase if you want to add hops to your garden. Rhizomes are available from most online and local home brew shops in the spring.
More recently they have become symbolic of sinister things. A snake ring worn on the first finger suggests this is an egotistical person and they are using the snake to enhance their status. A snake ring on the second finger suggests this is a materialistic person and they are using the snake to enhance their wealth.
In a dream, a snake could be a symbol of evil, treachery, medicine, healing or wisdom, as well as many other possibilities. To see a snake or be bitten by one in your dream signifies hidden fears and worries that are threatening you.
