Most people see only single-stem lady slippers in the wild so the Esteps' garden with nearly 80 flowers is a rare sight to come across.
Lady slippers are terrestrial orchids. One difference between terrestrial orchids and other orchids is their ability to tolerate cold. Many species survive in freezing temperatures, and some actually require sub-freezing conditions to bloom. Like tulips, these orchids go dormant through the cold weather months and grow and bloom again when spring arrives.
