US Plant Patent PP4217
Chrysanthemum plant
PUBLIC DOMAIN
Patent expired February 21, 1995. This plant is in the public domain — anyone may propagate and sell it.
Twenty years from the filing date would end on March 3, 1997, but this patent ends 741 days earlier — a terminal disclaimer gives term back. A source that calculates twenty years from filing would tell you this plant is still protected when it is already free.

No cultivar name of record
This patent does not name the plant, and for its era that is ordinary rather than an omission. Before about 1980, breeders frequently patented a plant without giving it a cultivar name at all — the grant identified it by its number, its parentage and a written description of the flower and foliage. Most plant patents from the 1930s to the 1970s have no name in them.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
A novel chrysanthemum characterized by long lasting blossoms having spooned, white ray florets enclosing a yellow anemone center.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
What is claimed is: 1. A new and distinct cultivar of chrysanthemum plant substantially as herein shown and described, characterized particularly as to novelty by anemone type flowers consisting of white spooned ray florets loosely arranged in 1 to 2 concentric rows about the yellow cushion of disc florets which results in the dainty, airy, bicolor appearance of the flowers, by the slow development of the flowers which remain attractive from their youngest open stage past full maturity resulting in long "shelf life", by the versatile nature of the flowers in that they may be grown either disbudded for increased size or in sprays for increased production of smaller flowers, by flower buds which develop normally in from 71/2 to 9 weeks from start of initiation throughout the year, and by strong, leafy plants which average 3 to 5 breaks per pinched plant making a showy display of 31/2" to 4" disbudded flowers or of 2" to 3" flowers borne in sprays.
