The Voynich Botanical Plants

Folio 22v. Tulips, are native to southern Europe, North Africa, and Asia. They are indigenous to mountainous areas with temperate climates and need a period of cool dormancy. They thrive in climates with long cool springs and dry summers. The variegated tulip, like the one shown in the VM folio, is the result of a viral infection. The virus weakens the plants so variegated tulips have been nearly eradicated. (C)
