Plants in the worldwide, but especially temperate Rose Family (Rosaceae) are annual and perennial herbs, subshrubs, shrubs (sometimes rambling), and trees with often spiny stems, simple or compound, alternate or opposite leaves, flowers with 0, 4, or 5 petals and 4 or 5 sepals, and fruit in the form of an achene, follicle, berry, drupe, or pome. Many species in this family are cultivated as ornamentals (roses, etc.) or for fruit (raspberries, apples, cherries, peaches, etc.).
