The Tiger Lily in its natural state is already operating at a level of visual drama that most flowers aspire to and few achieve — swept-back petals, spots, the general air of having just arrived from somewhere considerably more exciting than your garden. The Chartreuse version has taken all of this existing theatricality and made it the color of electricity given botanical form. The Chartreuse Tiger Lily is 4.75 inches across, hangs on one screw, needs no water. Which is either too much or exactly enough. We have decided it is exactly enough. The decision is final.
