Calabaza is the Spanish name for any type of pumpkin. In English, it refers to West Indian Pumpkin, or Calabassa, a winter squash grown in the Caribbean and Tropical America. Botanically, it is Curbita moschata.
At Richard Lyons Nursery it is grown under the rows of Jakfruit and Sapodilla trees. It is unfortunately a host plant for the Clabaza Squash Moth. The moth is a pollinator, however its caterpillars are very destructive defoliators.
Richard Lyons Nursery currently has this squash/pumpkin for sale.
