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.

The Fall Flower Show is over, but yesterday enough of the chrysanthemums were still in place for one last glimpse. These are hurried snapshots from a cell phone, but they give us some notion of the spectacle. Meanwhile, the Winter Flower Show is half installed, and already looks spectacular.
