When I was removing weeds and trimming plants for the winter yesterday (in Nassau County, New York), I collected 47 of these 1/4 inch in diameter pink purple and white round hard marbles. They also look like small hard grapes. They were mostly around the remnants of my collection of Amaryllis ‘Belladonna Lily Pink Hybrids (Naked Ladies)’ but some of them were up to 10 feet away in either direction. Below are links to photos of those plants and its flowers when they were blooming in my garden. I cannot see how these marbles came from that plant so they may be remnants of some weed but I never saw them hanging from any weed that I removed. I do not know if they are seeds or the remnants of flowers. If anybody knows what they are or anybody wants a few to try planting, please let me know.
