Variegated Maiden Grass. Variegatus is an antique maiden grass cultivar that has been in cultivation since the 18th century. The grass grows to 8 feet tall, with a spread of about 5 feet, producing light green leaves striped with white. In the fall, the grass boasts pink flowers.
You can think of elements as different sized marbles (except, in this case, the marbles are all very, very tiny!). Based on the relative sizes of the marbles, they can be stacked in different ways (see the figure). A good example of a simple mineral is table salt (Yes, salt is a mineral.). The proper mineral name for table salt is halite, and a geologist will often identify it by tasting it. Salt is composed of two elements; Sodium (Na) and Chlorine (Cl). Sodium and chlorine are strongly attracted to each other and stack together into a cubic crystal structure (see figure).
Natural sea salt has little parts and pieces of other minerals besides sodium chloride. Rock salts that can be eaten are sometimes a little grayish in color because of these other minerals. Sodium (Na) and chlorine (Cl) are the two elements that make up sodium chloride. Both of these are needed for all living creatures, including humans, but they are not always eaten in the form of salt, where they are found together in large amounts.
