toringo crab apple 'Aros'


The Malus toringo 'Aros', commonly known as the crabapple 'Aros', is an ornamental plant celebrated for its striking appearance throughout the seasons. The foliage of this plant is particularly noteworthy, characterized by its unique dark purple, almost black leaves that maintain their color intensity from spring until fall. The leaves are typically small, with a rounded and slightly serrated edge, attached to the branches by short stems. In spring, the crabapple 'Aros' becomes a focal point in gardens with its profuse floral display. The flowers burst forth in a dramatic contrast to the dark foliage, with blooms that are commonly a delicate shade of pink. These flowers are small, typically with five petals, and cluster together, creating an enchanting and dense floral canopy that is attractive to pollinators such as bees. Following the flowering period, the crabapple 'Aros' produces distinctive fruit. These small apples are usually less than an inch in diameter and can range in color from dark red to purplish, complementing the overall color scheme of the plant. While not typically consumed by humans due to their tartness, these crabapples are often appreciated by birds and wildlife and can add winter interest to the landscape as they may persist on the tree after the leaves have fallen. The branches of the crabapple 'Aros' are elegantly structured, creating a visual interest that is particularly notable during the winter months when the leaves have dropped, revealing the intricate framework of the tree. The bark itself is smooth, contributing to the plant's refined appearance. Overall, the crabapple 'Aros' is admired for its year-round beauty, from the strikingly colored leaves and charming spring blossoms to the eye-catching miniature fruit and elegant branch structure. This plant is a popular choice for gardeners looking to add dramatic color and varied interest to their landscapes.

  • skullToxicity

    • To humans

      Malus toringo 'Aros', commonly known as the Sargent Crabapple, is not considered significantly toxic to humans. However, caution should be exercised because consuming large quantities of seeds from the crabapple can be harmful. The seeds contain a compound called amygdalin, which can release cyanide when metabolized. Ingesting a few seeds is unlikely to cause harm, but consuming them in large amounts could lead to symptoms of cyanide poisoning, which may include headache, nausea, vomiting, abdominal pain, dizziness, and in severe cases, respiratory failure and death.

    • To pets

      The Sargent Crabapple is generally considered non-toxic to pets as well. However, similar to humans, the seeds contain amygdalin and can potentially release cyanide when digested. While a pet is unlikely to access or consume enough seeds to cause harm, ingestion of a large number of seeds could potentially lead to cyanide poisoning. Symptoms of poisoning in pets might include dilated pupils, difficulty breathing, panting, shock, and in severe cases, coma or death. It is always best to prevent your pets from consuming any part of plants that have potential toxicity.

    The Crabapple 'Aros' should be watered regularly to keep the soil evenly moist, especially during dry spells or in the growing season. It's best to water deeply once a week, providing about 1 to 1.5 inches of water each time. This corresponds to approximately 0.6 to 0.9 gallons for a young tree, depending on the size and the soil's moisture-holding capacity. During the winter, reduce watering to match the plant's dormant state and only water if the soil becomes very dry. Always check the soil moisture at a depth of a few inches and water if it's dry to the touch.

  • sunLight

    The Crabapple 'Aros' thrives in full sun which means it requires at least six hours of direct sunlight each day for optimal growth and bloom. It's important to plant it in a location where it can enjoy uninterrupted sunlight, away from taller structures or trees that might cast shade on it. Varieties like 'Aros' can tolerate a bit of light shade, but flowering and fruiting are best in full sun.

  • thermometerTemperature

    The Crabapple 'Aros' is hardy and tolerates a range of temperatures, thriving in conditions that are typically between 60°F and 75°F. It can withstand winter chill down to -20°F and summer heat up to 90°F. Plant 'Aros' in regions where typical seasonal temperatures remain within these bounds to ensure good health and growth.

  • scissorsPruning

    The Crabapple 'Aros' requires pruning to maintain its shape, remove any dead or diseased wood, and encourage healthy growth and flowering. Pruning should be carried out in late winter or early spring before the new growth starts. It's often ideal to prune just after the worst of winter's cold has passed but before the tree enters its spring growth phase.

  • circleLife cycle

    Malus toringo 'Aros', commonly known as Crabapple 'Aros', begins its life cycle when seeds germinate in spring, given suitable moist soil and sunlight conditions. Seedlings emerge and develop into juvenile plants, forming a small shrub-like structure. As the plant matures, it undergoes a vegetative stage characterized by the growth of dark purple, almost black leaves and a compact, upright habit. During spring, the mature crabapple 'Aros' produces striking dark red-pink blossoms that, if pollinated, will give way to small, ornamental purplish-black apples by late summer. These fruits can persist into winter, providing visual interest and a food source for wildlife. Over many years, the crabapple 'Aros' plant will reach its full size and may eventually decline with age after several decades, completing its life cycle.

      Spring-Early Summer

    • Malus toringo 'Aros', commonly known as the Sargent crabapple 'Aros', is typically propagated through grafting, which is the most popular method for this ornamental tree. Grafting involves joining a piece of a mature, productive Sargent crabapple 'Aros' (the scion) to a healthy rootstock of another Malus species that has desirable root traits. This is usually done during the dormant season, commonly in late winter to early spring. The scion, which is a twig with several buds, is selected from the desired 'Aros' cultivar and is carefully joined to the rootstock using a variation of grafting techniques such as whip grafting or cleft grafting. The graft union is then sealed with grafting tape or wax to prevent drying and disease entry. Within a few weeks to months, the tissues of the scion and rootstock grow together, resulting in a new tree that combines the ornamental characteristics of 'Aros' with the rootstock's vigor and disease resistance.
