    Nursery contributed plant descriptions

    Graceful of habit & PERENNIAL, we adore this original ancestor of modern Petunias. Introduced into cultivation in 1837, we’re lucky to get seed from the U.C. Botanical Garden in Berkeley, CA. Large, 2.5” across, pure white flowers bloom from Spring to Fall, forming a 2x2’ mound of blooms that tastefully twirls itself around taller neighbors up to 4’. Night scented of vanilla & licorice, it’s pollinated by those amazing hawkmoths.
