Forelle pears are almost as small as seckels. They are yellow-green with red patches. A relative of ebony, the persimmon tree is a source of hard, strong wood that has traditionally been used to make golf club heads. Kakis were introduced into France and the Mediterranean in the 19th century and, soon after that, brought to California.
