Tower Hill’s Orchid Show is inspired by the vibrant colors of street art and blends custom-made graffiti art by local Worcester artist Croc and stunning plant displays created by our Horticultural team. As you explore the Limonaia and Milton Gallery, we invite you to enjoy the art and plant displays featuring over 500 orchids. Discover the complex relationships between animals (humans included!) and their environment.

Street art adds color and highlights the vibrancy of urban, public spaces which often have little plant life. By combining the two we hope to encourage discussion about the relationship we have with nature and to highlight the value of diversity in both people and nature.

About Orchids: There are more than 22,000 species in the orchid family (Orchidaceae), making it the second largest flowering plant family. Orchids are extremely adaptable, and grow on every continent in the world except Antiartica. Orchid species can differ greatly from one another, in size, weight, and color. Orchid flowers range from no more than 0.1 inch to over a foot long. Orchids fall into two main categories: epiphytic (growing with roots above ground) and terrestrial (growing with roots in the ground).

Orchid flowers also have several unique physical traits that make them stand out. All orchids have three sepals (modified leaves) and three petals, one of which, called the labellum or lip, is specialized to attract pollinators. The lip is usually very colorful or has a special shape to attract insects for pollination; it also serves as a landing pad for visiting insects. Unlike most flowers, the male and female parts in orchids are combined into the column. Click here to read more about orchids and their pollinators.
