Glossary

Farina

Growers call it the powdery blue-gray bloom on the skin of some plants. It rubs off, so oils, sprays and scrubbing remove it, growers say.

Farina is a powder sitting on the skin, not a color in it. Wipe a finger across a blue plant and the green underneath comes straight through — which is also why a plant handled a lot stops looking blue.It grows back on new growth. It does not come back on the piece you rubbed.
