First flower of a Bloodroot , Sanguinaria canadensis
It never ceases to amaze me what joy a tiny flower can evoke. Each plant (or more correctly each stem arising from the rhizome) produce only a single flower wrapped by a single furled leaf making each more precious.
From Wikipedia: "Bloodroot is also known as bloodwort, red puccoon root, and sometimes pauson. Bloodroot has also been known as tetterwort in America, although that name is used in Britain to refer to Greater Celandine."
And: "Bloodroot is one of many plants whose seeds are spread by ants, a process called myrmecochory. The seeds have a fleshy organ called an elaiosome that attracts ants. The ants take the seeds to their nest, where they eat the elaiosomes, and put the seeds in their nest debris, where they are protected until they germinate. They also get the added bonus of growing in a medium made richer by the ant nest debris."
