Millington Greenhouse The 4000 square foot greenhouse on the roof of Millington Hall was built in 1969 and is slated to be rebuilt within the next few years. The greenhouse maintains quite a large collection of orchids: This plant gets its name from the spines that guard the stems: Crown of Thorns (Euphorbia Splendens). The picture on the left is of a beautifully flowering specimen of Veltheimia glauca.
