Medlar. A member of the pear family, medlar bears interesting fruits (figure A)--flat and quite large--and they're edible only when they've split apart and completely softened. Eating a medlar fruit too soon can be like eating an unripe persimmon.Although it's not readily available in North America, it is worth the search. Adds Nancy Moore. "There is a lot of sexual innuendo connected with this plant in Romeo and Juliet. So if you like live on the racy side, this would be an interesting plant to have." Medlar is hardy to USDA Zone 4.
Mulberry tree. Shakespeare had a mulberry tree (figure B) in his garden. It's hardy to USDA Zone 4 and can grow up to 40 feet tall. If you decide to add one to your garden, opt for a seedless variety.
Rose. The rose (figure C) is the plant that's mentioned the most in Shakespeare's plays. The red rose of Lancaster is mentioned in the War of the Roses.
Historical roses are known as heritage roses. The white form is the alba rose and the red is the gallica. Both are very fragrant and disease-resistant. They are used for making potpourri. In Shakespeare's time, the flowers would have been used for strewing in the home.
Herbs. Playing a very important role in Shakespeare's works, herbs were used to mask poor hygiene. Lavender means "to wash" but it was actually used by Elizabethans who didn't.
"They wore it as a posy or carry it as a little bouquet simply because it alleviated some body odor," says Moore.
