Wikijunior:Summer Flowers of Northern New England/Rosa
Roses are familiar to almost anyone who loves flowers. However, the roses you buy from a florist or see in the grocery store do not look a whole lot like the wild ones you might find out in a field. Wild roses have five petals. The flowers are showy and large, usually an inch or two across. The center of the flower has many yellow stamens (stay-mins) which are little thread-like structures. The leaves generally have toothy edges. The plant itself grows anywhere from one to six feet tall. The stems are often thorny.
In the fall, the flowers turn into rose hips, which are small round fruits.
