This is the species that is used as THE cultivated walnut tree. It has pinnately compound leaves with about 7 alternate leaflets, larger towards the tip or terminal end.
Humans have enjoyed these nuts for so long that in many languages the word for nut is a word for THIS nut. Its original range is long forgotten, but it is grown across Eurasia, with China being the largest exporter for the worldwide market.
This WHITE little plant completely lacks chlorophyll and is often mistaken for a fungus or mushroom. In truth, it is a parasite of fungi that feed on tree roots, and is often found in the shade beneath beech or maple trees.
The brilliant blue, white, or pink of these flowers are actually 5 to 25 colored sepals rather than petals. They appear to float upon a mist of thread-like bracts above feathery, pinnately divided leaves.
