The Rose Family is also known as Rosaceae. When Rosacea is defined widely, it contains somewhere between about one thousand two hundred and three thousand and four hundred species, in about one hundred to one hundred and twenty two genera. This includes such diverse members as Apples, Hawthorns, Pears, Quince, Roses, Strawberries, and Dewberries. Also, Rosacea contains the Stone Fruits, which includes almonds, apricots, cherries nectarines, peaches, and plums. There is still at least a hundred other genera. Rosacea also includes thousands of cultivated varieties.
Most of the members of Rosacea have rather flat flowers that have five sepals, five petals and have wavy margins, with ten to many stamens. Also the members of Rosaceae that show up in the wild. Never have blue flowers, or red flowers. This is because Rosacea lacks the genes to produce true blue or pure red flower pigments.
Rosacea is of much importance, because it is a plant of worldwide importance. Such as the worlds most widely grown tree fruit the apple and also many other species. Rosacea is scattered throughout the world. Rosacea has relatively few important timber species, but many or the species are very important because of their edible fruit and/or ornamental value. Some ornamental plant members of the Rosacea are the crabb Apples (malus), hybrid Tea rose, Rosa "Eclipse.".
Some very important members of Rosacea are Apples, also known as malus and contains somewhere around thirty species of trees and shrubs in the Northern Hemisphere. Introduced to the U.S. during the colonial times. There is also Blackberries, also known as Rubus. Rubus contains somewhere around four hundred species of small shrubs and they are generally found in cold-climate regions of the Northern Hemisphere. New cones (stems) normally produce each year; cones live two years and flower fruit during the second year. Their leaves are generally compound and the cones usually have prickles.
