What is mosspink?
Basically it's a flowering plant (see photo on right), often used as a ground cover because of its low-growing nature and its ability to thrive in even the worst conditions. At times it is considered a weed because it can be invasive.

Why mosspink?
To answer this second most asked question I will quote in almost its entirety my very first blog entry from Dec. 29, 2001:

Back in college, Mike W. and I were tripping and traipsing through the U.C. Berkeley Botanical Gardens on a warm spring day. After experiencing a fit of laughter which landed me on a stone paver, I looked up at a simple but beautiful flower. Its name was mosspink and it was quite arresting. ... Mosspink's ability to thrive in adverse conditions, its low-growing humbleness, and its perkiness in any environment all struck a chord with me. And so, I decided to adopt it as a personal mascot from that day on.

Why isn't mosspink moss- or pink-colored?
From what I know, the "moss" part of this plant derives from the fact that it grows low and is often found on rocks, much like real moss. "Pink" is the common name for a carnation.

Anything else?
