The Winter Flower Show has always involved lights, but this year Phipps pulled out all the stops—especially in the outdoor garden, where glowing shapes constantly change colors.

A blue Vanda. Blue is the rarest color in the orchid family, and even the blue Vandas only approach blue by way of violet.

A Dendrobium hybrid.

A Stanhopea, whose incredibly complex flowers have clever mechanics that trap the pollinating insect until it has done its job very thoroughly.

Probably some sort of Laeliocattleya hybrid.

A Paphiopedilum.

Though miniaturized through the use of advanced transistor technology, this azalea still manages to put on a good display for the Spring Flower Show.

Hebe, the Greek goddess of youth and the cupbearer of Olympus, stands in the middle of a riotously colorful Victorian patchwork garden in Phipps Conservatory.

The Spring Flower Show is going on right now at Phipps Conservatory, and here are some of the stars.
