hiomapinnasta

Hiomapinnasta, also known as the **Finnish maple leaf** (*Acer platanoides* 'Crimson King'), is a popular ornamental tree cultivar valued for its striking foliage and compact growth habit. Originating from a chance seedling discovered in Finland, this cultivar was developed for its dense, rounded canopy and vibrant autumn colors, which range from deep purple to brilliant red. Unlike its wild counterpart, the Norway maple (*Acer platanoides*), the Crimson King exhibits consistent coloration and a more manageable size, typically reaching 12–15 meters (40–50 feet) in height with a similar spread.

The tree is widely planted in urban landscapes, parks, and gardens due to its adaptability to various soil types, though it thrives best in well-drained, slightly acidic to neutral soil. It tolerates urban pollution and partial shade, making it suitable for street plantings and small urban spaces. Its leaves are palmately lobed, resembling those of the American sugar maple (*Acer saccharum*), but with a glossier texture and more pronounced veins. In spring, the tree produces clusters of greenish-yellow flowers, followed by winged samaras that disperse seeds in autumn.

Hiomapinnasta is often confused with other maple cultivars, such as 'Schwedler' or 'Globosum,' which share similar compact forms but may differ in leaf color or growth rate. While generally low-maintenance, it may require occasional pruning to maintain its shape and remove deadwood. The cultivar is hardy in USDA zones 4–7 and is particularly popular in Nordic and temperate climates, where its vivid foliage enhances seasonal interest.

Beyond its ornamental use, the Crimson King maple contributes to biodiversity by supporting pollinators with its spring flowers and providing shelter for birds. However, its seeds can become a nuisance if left unchecked, as they may self-sow in gardens. Overall, hiomapinnasta remains a favored choice for landscapers and homeowners seeking a striking, low-maintenance tree with seasonal color.
