The Norway maple 'Globosum', often known for its unique rounded shape, stands out with its dense and neatly symmetrical crown. This well-proportioned deciduous tree displays a luscious, deep green canopy with broad leaves that have a classic maple shape, boasting five distinctive lobes with finely toothed margins. The leafy dome emerges with a delightful hint of reddish tint in spring, transitions to a steadfast green in summer, and then treats onlookers to a glorious display of yellow hues in the fall, signaling the change of seasons. Small, attractive yellow-green flowers may be observed in clusters as the foliage unfolds, providing an additional visual interest and attracting pollinators to the garden. The bark of the tree maintains a subtle grey-brown shade, presenting a smooth texture that becomes more rugged with age.

  • water dropWater

    The Globe Norway Maple should be watered deeply and regularly during its first growing season to establish a deep root system. After establishment, water the tree less frequently, but still deeply, to encourage root growth. Typically, providing 1 to 1.5 gallons of water once a week should suffice, with increased amounts during periods of drought. Overwatering or allowing the tree to sit in soggy soil can lead to root rot, so ensure the soil drains well.

  • sunLight

    The Globe Norway Maple thrives in full sun to partial shade. It is best situated in a location where it receives at least six hours of direct sunlight daily, but it can tolerate some light shade, especially during the hot afternoon hours. Avoid deep shade, as this can lead to reduced vigor and sparse foliage.

  • thermometerTemperature

    The Globe Norway Maple can withstand a wide range of temperatures, suitable for USDA zones 4 through 7. It can survive minimum winter temperatures down to -30°F and can handle summer temperatures well into the high 80s°F. The ideal temperature range for this maple is between 50°F and 75°F to encourage optimal growth.

  • scissorsPruning

    The Globe Norway Maple should be pruned to shape it and remove any damaged or diseased branches, best done in late winter or early spring before the sap starts to flow. Prune sparingly to maintain its natural round shape, and avoid heavy pruning as this can lead to excessive growth of undesirable shoots. Inspect the tree annually for pruning needs.

  • circleLife cycle

    The Norway Maple 'Globosum' begins its life when a viable seed from a mature tree germinates in a suitable environment, typically in spring. After germination, the seedling emerges and establishes roots and shoots, entering the juvenile growth phase where it focuses on developing a robust root system and foliage. As the sapling grows, it enters a vegetative state, characterized by the expansion of its distinctive globe-shaped crown made up of dense, lush foliage. Over several years, the tree reaches maturity and begins to reproduce, producing small yellow-green flowers in early spring that are followed by the development of characteristic winged fruits called samaras. These samaras disperse by wind, allowing new seeds to spread and potentially germinate to continue the species' life cycle. In its mature stage, the Norway Maple 'Globosum' can live for decades, contributing to the ecosystem by providing shade, habitat, and seasonal autumn color before eventually senescing and dying, completing its life cycle.

      Spring-early summer

    • The Norway Maple 'Globosum', scientifically known as Acer platanoides 'Globosum', is commonly propagated by grafting, which is the most popular method for this particular cultivar. Grafting is usually performed in late winter or early spring before the sap begins to flow. The process involves taking a scion, which is a cutting from a desired parent tree that includes buds, and attaching it to a rootstock, which is a seedling or a young tree that provides the root system. The scion and the rootstock are cut at matching angles, bound with grafting tape and often sealed with wax to prevent drying out. This joins the vascular systems of the two, allowing them to grow together and form a new tree that possesses the desired characteristics of the 'Globosum' canopy but with the hardiness of the rootstock's root system.
