That is a reasonable description, it does look like a stinging nettle but the two plants are not related. Urtica dioica, the Stinging Nettle is a member of the Urticaceae or Nettle Family and White Dead-nettle is a member of the Mint family.
Unlike the Nettle family the Dead-nettles don’t have a sting.
You can’t really confuse the two plants, the flowers are the give away and they start to form almost as soon as the plant appears.
Like other Dead-nettles Lamium album has a square stem.
The leaves are described as cordate (heart shaped) to ovate (oval with a tapering point). They are deeply veined with a net pattern and the edges are toothed. They are also covered in soft hair on both sides.
The White Dead-nettle is described as having a three lobed lower lip, It has a large central lobe, the two outside lobes are the very small tooth like projections either side of the central lobe in this next picture. They are fairly insignificant.
It is a valuable wild life plant providing a good source of nectar early in the year. It is very popular with bees and is sometimes known as the Bee Nettle. It is the food plant for a number of beetles and moths, including the Golden-Y Moth, the Rivulet, the Burnished Brass and the Speckled Yellow.
