When reviewing online nurseries selling this coreopsis, I see that all have some non-descript tag or asterisk that probably raises no red flag for most people (like me.) Only after some sleuthing does one learn what the nomenclature and anacronyms refer to. Can I be fined by the Plant Police (um. . . I mean the 'Plant Variety Protection Office') if I divide the plant? Will I be hauled off to the slammer if the plant decides to reproduce itself? Not to worry - the plant is sterile, probably bred that way to prevent unauthorized propagation.
So who holds the patent? I cannot find that information online at the Patent and Trademark Office. I did find PP#18183 (the number before #18184 coreopsis) is an Alstroemeria. I also found the following information about plant patents at the US -PTO Office:
The law provides for the granting of a patent to anyone who has invented or discovered and asexually reproduced any distinct and new variety of plant, including cultivated sports, mutants, hybrids, and newly found seedlings, other than a tuber-propagated plant or a plant found in an uncultivated state.
Three or four blooms created only disappointment when it was planted last spring. After a summer pampering and a hearty winter, the plant peeked out in late spring, then bolted into the loose, lacy mound of foliage now exhibited. Blossoms are coming on strong and are incredibly interesting.
Two-color petals attract attention without the gaudiness they would on a larger plant. Don't believe the photos in the catalogs (as if you ever do.) Although the coreopsis has grown into a foot high mound (30 cm), it is anything but thick and dense. Descriptions also state "Attracts butterflies and bees." Attracting nothing here. "Forms a compact mound." Try sparse and floppy. "Blooms repeatedly." Maybe later this year.
If you want a piece of the action (er, a piece of Autumn Blush) at our next plant swap, meet me in the parking lot - I will be the one in the trench coat and sunglasses carrying the brown paper bag.
