Crimson King Maple Acer platanoides 'Crimson King'
The Crimson King maple is distinguished for its eye-catching foliage that sets a dramatic tone in the landscape. This ornamental tree showcases leaves that are a deep, rich maroon or burgundy throughout the growing season, contrasting sharply with the more typical green of other trees. The leaves are shaped like a classic maple leaf, with five pointed lobes, and are arranged in an opposite leaf configuration on the branches. During the spring, small flowers may appear, adding a subtle flourish to the tree's overall visual impact. These flowers are usually followed by samaras, which are the winged fruits characteristic of maples, often known colloquially as helicopters due to their swirling descent to the ground. The Crimson King maple has a dense and rounded crown, presenting a full, lush appearance. Its bark is gray and fairly smooth when the tree is young, but as it matures, the bark develops furrows, and the texture becomes more rugged and corky. Its striking coloration and attractive form make the Crimson King maple a sought-after choice for those looking to make a statement in their landscapes with a bold splash of color that endures from spring until fall.

The Crimson King Maple requires watering once or twice a week, providing deep irrigation to help establish a robust root system. During dry spells or extreme heat, increase the frequency to ensure the soil remains consistently moist but not waterlogged. Provide the tree with 10 to 15 gallons of water per session, making sure to water slowly at the base to allow for deep soil penetration. Adjust the amount and frequency as needed based on rainfall, temperature, and soil conditions.
The Crimson King Maple thrives in a location that receives full sun to partial shade. The ideal spot would allow for at least six hours of direct sunlight daily, with some protection from harsh afternoon sun. Ensure that the tree is planted in a space where it has room to grow both upwards and outwards without being shaded by nearby structures or trees.
The Crimson King Maple is hardy and adaptable, tolerating a wide range of temperatures. Ideal growth occurs between 60°F and 70°F, but the tree can survive in temperatures as low as -40°F and as high as 90°F. It is important to avoid temperature extremes during the initial planting and establishment phase to reduce stress on the young tree.
Pruning the Crimson King Maple is necessary to remove any dead, damaged, or diseased branches and to maintain its shape. The best time for pruning is in late winter or early spring before the sap starts to flow. Prune sparingly and selectively, as this tree can be sensitive to heavy cutting. Depending on growth and structural integrity, pruning may be needed once every 3 to 5 years.
The 'Crimson King' Norway Maple thrives in moist, well-draining soil enhanced with organic matter, and prefers a pH ranging from 5.5 to 7.5. A balanced soil mix containing loam, compost, and sand or perlite can support healthy growth.
'Crimson King' Norway Maples are large trees and do not typically require repotting as they are often planted directly in the ground. However, younger trees might need to be transplanted every few years until they are established.

- Life cycle
The Norway Maple 'Crimson King' begins its life with seed germination in the spring, following dispersal from the parent tree in autumn. The seedling establishes itself with primary leaves and begins to form a taproot. It progresses into a juvenile phase where it develops a woody stem and true leaves, distinctive for their crimson-purple color. As it matures into an adult tree, it develops a round-to-oval crown and starts flowering typically after 5-7 years, producing small yellow-green flowers that are followed by characteristic winged samaras. The tree reaches reproductive maturity and enters a period of growth and reproduction, producing seeds annually. In its final stage of life, the Norway Maple 'Crimson King' may experience a decline in vigor, potentially succumbing to environmental stressors, pests, or diseases, leading to senescence and eventually death.
Late winter-early spring
The Norway Maple 'Crimson King' can be propagated through various methods, but the most popular way to propagate this tree is by seed. The seeds, or samaras, should be collected in the fall once they have turned brown and begin to drop from the tree. Seeds require a period of cold stratification to break dormancy; this can be accomplished by mixing the seeds with moist sand or peat moss and storing them in a refrigerator for around 90 to 120 days at temperatures between 33 to 41 degrees Fahrenheit (1 to 5 degrees Celsius). After stratification, seeds can be sown in pots or in a prepared seedbed, ideally in the spring. The seeds should be planted about half an inch (1.27 centimeters) deep and kept consistently moist until germination, which can take several weeks. Once the seedlings have established, they can eventually be transplanted outdoors to their permanent location.
