Pumpkin-on-a-Stick is another ornamental crop harvested for its attractive fruit-bearing stems, this species is a relative of eggplant, and shares some of its diseases and insect pests. Pumpkin on a Stick has been delighting gardeners for more than 125 years, and goes by many names. Some call it Pumpkin Tree or Pumpkin Bush, because of the sturdy, long-lasting branches set with large purple thorns. Others call it Mock Tomato, because it really does resemble a heavily ribbed tomato, especially when the fruits first turn from green to scarlet. They won’t get their pumpkin-orange tones until they begin to dry out. Still others know it as Hmong Eggplant, Red China Eggplant, or Scarlet Chinese Eggplant, reflecting its origin in Southeast Asia.
