Grow it: This sun-loving plant needs good drainage. Use a small pot filled with gravel and a light soil.
Use it: It has antiseptic and anti-inflammatory properties. Crush a handful of the heads and add to a bowl of boiling water to use as a steam bath for your face. You can also dab the oil from the flowers on blemishes, says Marrone.
