Malus
The genus of apples and crabapples with spring blossoms and autumn fruit
Malus is a group of small deciduous trees and shrubs in the rose family, known for apples and crabapples. Native to temperate regions of the Northern Hemisphere, these trees have showy spring flowers and bear fruit that ranges from sour wild apples to sweet cultivated varieties.
- Malus includes apples, crabapples, and wild apples
- Flowers are white, pink, or red and bloom in spring
- Fruit size ranges from small wild crabapples to large cultivated apples
- Crabapples are used as rootstocks and pollinizers in orchards
- Seeds contain cyanide compounds and are toxic if eaten
What does Malus look like?
Malus trees are small to medium-sized, typically reaching 4 to 12 metres in height. They have a dense, twiggy crown and simple, serrated leaves. In spring, clusters of five-petalled flowers appear, ranging in colour from white to pink or red. The fruit, known as an apple or crabapple, is round and varies in size from small wild types to large cultivated apples. The seeds inside the fruit contain cyanide compounds.
Where does Malus come from?
Malus is native to the temperate regions of the Northern Hemisphere. Fossil records show the genus has existed since the Eocene, with ancient species found in North America, Russia, and China. Over time, Malus species have hybridized freely, leading to a wide variety of apples and crabapples. The domesticated apple, along with many wild and ornamental forms, all belong to this genus.
When and how Malus blooms
Malus trees bloom in spring, after accumulating enough warmth. Most species require cross-pollination by insects, especially bees, though some cultivars can self-pollinate. Crabapples are often grown as ornamental trees for their blossoms and persistent fruit, and are also used as rootstocks to improve cultivated apples. The trees thrive in temperate climates and are grown from seed or by grafting.
How Malus is used
Crabapples are valued for their spring flowers and colourful autumn fruit, making them popular in gardens and as bonsai. The fruit is usually too sour to eat raw but is used in jellies, as a condiment, and sometimes in cider. Crabapples are also used as pollinizers in apple orchards. The wood is prized for its slow-burning, fragrant smoke and for making tool handles.
Kinds of Malus
The genus includes about 32–57 species and many hybrids. Cultivated apples (Malus domestica) and various crabapples differ in fruit size, taste, and ornamental qualities. Some crabapple cultivars have won horticultural awards for their garden value. Fossil species show the genus has a long evolutionary history, with forms once native to North America, Russia, China, and Romania.
What Malus means
Malus trees are widely grown for their beauty and fruit. Crabapples are important in ornamental horticulture and are sometimes used as emblems or symbols. In some Southeast Asian cultures, the fruit is eaten with spices as a sour treat. The wood has been valued for toolmaking and smoking foods. Seeds are toxic due to cyanide compounds.
