Walnut is a common name for about 20 distinct species such as deciduous trees.
Approximately six of these grow in Northern America, the USA and Canada. These have a tendency to be of a darker variety since the sample here shows. The walnut itself will display a number of the linear lines but you will also see marblezation and swirls within the grain pattern.
Quite frequently the sapwood for what the milder parts will look naturally as a yellow or syruppy color. These are subsequently stained, darken the wood and give it complete a more consistent tone.
Whilst it is not quite a robust or as durable as oak, typically the floors will be tremendously finished with a number of layers of security. Other species of walnut derived from Europe, Asia and South America, though these are inclined to be milder and more will have more color variation.
