Kwanzan Cherry, Prunus Kanzan

The Kwanzan Cherry, known scientifically as Prunus serrulata 'Kwanzan', is a highly popular ornamental cherry tree noted for its profuse and showy pink blossoms.

Here's a list of facts about this beautiful tree:

Origins: The Kwanzan Cherry is native to Japan, and it's named after a mountain there. It's one of the most popular cherry blossom trees in Japan and has been widely planted around the world, especially in temperate climates.

Blossoms: The tree is famous for its large, double-pink flowers, which bloom in clusters making a very striking display. Unlike some other cherry trees, Kwanzan Cherry blossoms are not fragrant.

Leaves: After the flowering season, the tree has attractive, dark green leaves that turn to yellow, orange, or bronze in the fall, adding seasonal interest.

Growth Habit: The Kwanzan Cherry grows to a height of 30-40 feet (9-12 meters) and has a vase-shaped growth pattern that becomes rounder with age. It's known for its upright branches, making it a good choice for street or lawn planting.

Lifespan: While stunningly beautiful, Kwanzan Cherry trees have a relatively short lifespan, typically around 15-25 years, which can be even shorter in urban conditions due to stress factors like pollution, compacted soil, and limited space.

Planting Conditions: This tree prefers well-drained, moist soil and a sunny to a partly sunny location. It's relatively adaptable but doesn't do well in extremely wet or dry conditions.

Maintenance: Kwanzan Cherry trees require some maintenance, including regular watering, especially in dry periods, and occasional pruning to remove dead or crossing branches and to maintain shape.

Pests and Diseases: They can be susceptible to pests and diseases like aphids, spider mites, and fungal infections such as cherry leaf spot and powdery mildew. Proper care and monitoring can help minimize these issues.

Non-Fruit Bearing: Unlike its fruit-bearing relatives, the Kwanzan Cherry does not produce edible fruit. The fruit is bitter and has little edible flesh.

Cultural Significance: Cherry blossoms, including those of the Kwanzan Cherry, hold significant cultural importance in Japan, symbolizing the transient nature of life due to their short blooming period. The annual cherry blossom festivals in Japan and other countries celebrate this aspect with great enthusiasm.

These facts highlight the Kwanzan Cherry's beauty and popularity as an ornamental tree, despite some of its challenges and limitations.

Juneberry, Amelanchier

Juneberries, also known by various names such as saskatoon, serviceberry, and shadbush, are small, woody, and multi-stemmed shrubs or trees that thrive in a variety of climates and soil types, including swamps, woods, and thickets. They prefer rich loamy soil but can grow in heavy clay soils and are more wet-tolerant than other members of their genus. These plants can reach 20 to 30 feet in height and have a lifespan of up to 50 years in the wild. Their fruit is small, berry-like, and matures to a dark purplish-black color, offering several health benefits such as a stronger immune system, healthier skin, and reduced risk of heart disease and cancer​​.

Juneberries are often confused with blueberries due to their similar appearance, but they are technically a pome fruit, closely related to apples and pears. They have a detectable almond flavor when eaten fresh, which becomes more pronounced when cooked into pies or cobblers. Despite their delicious taste, juneberries have not been widely commercialized, although efforts are being made to change this, particularly in Canada and the United States. They are easy to grow, not as finicky as blueberries regarding soil pH, and bloom early in the spring, providing an early fruit harvest around the 4th of July in the Northeast​​.

Research led by Cornell University indicates that juneberries are winter-hardy and can grow in USDA zones 2 through 5, making them a resilient fruit crop for colder climates. Initial consumer taste testing suggests a promising future for juneberries in the market, with many consumers liking their flavor and nutritional benefits. However, challenges such as consumer familiarity and pest management still need to be addressed for larger-scale cultivation​​.

Japanese stewartia, Stewartia pseudocamellia

The Japanese Stewartia, known scientifically as Stewartia pseudocamellia, is a small to medium-sized deciduous tree that is native to Japan and Korea. It is valued for its multi-seasonal interest, featuring white, Camellia-like flowers with gold stamens in the center during the summer, and green to brownish fruit capsules. This tree is particularly noted for not having serious insect or disease problems, making it a relatively low-maintenance choice for gardens.

It can grow to a height of 12 to 40 feet and a width of 8 to 25 feet, and it thrives in full sun to partial shade conditions. The Japanese Stewartia prefers evenly moist, organically rich, moderately acidic, well-drained sandy loams. It doesn't do well in heavy, clay, dry, thin, rocky soils, or soils with poor drainage. Consistent moisture is important for this tree, and it is intolerant of drought conditions. Partly shaded conditions are recommended in climates with hot, humid summers to avoid the stress of afternoon sun.

There are several cultivars of the Japanese Stewartia, each with unique characteristics. For example, 'Ballet' has a spreading habit and large flowers, 'Cascade' has a semi-weeping habit with red-purple fall foliage, and 'Milk and Honey' is known for its profuse flowering and bright bark color. Other cultivars include 'Harold Hillier' with excellent fall color, 'Julia' with large white flowers, 'Mint Frills' with pale greenish flowers, 'Pilar Bella' with a columnar habit and large flowers, and a rare 'Pink Form' with whitish-pink flowers and pink buds.

Jacaranda, Jacaranda mimosifolia

Jacaranda mimosifolia, commonly known as the blue jacaranda, is a sub-tropical tree originally from south-central South America, specifically southern Brazil, northwestern Argentina, and southern Bolivia. It's known for its stunning and long-lasting violet-colored flowers and has been widely planted around the world for its ornamental value. The tree is capable of reaching heights of 25-50 feet with a spreading crown that can extend 15-30 feet wide. Its leaves are fern-like, bi-pinnate, and can reach up to 20 inches in length, turning brown in the autumn. The blue jacaranda produces fruit in the form of woody seedpods that are mahogany-colored and round, opening to reveal several winged seeds. The bark of mature trees takes on a finely scaly appearance and texture​​​​.

In its native range, the jacaranda is threatened by uncontrolled logging and land clearing for agriculture, leading to its classification as Vulnerable on the IUCN Red List. Despite its beauty, the jacaranda is considered an invasive species in some regions, such as parts of South Africa and Queensland, Australia, where it can out-compete native species​​.

Jacarandas are known for their preference for full sun and sandy soil with good drainage. Once established, they are quite drought-tolerant, although they are not salt-tolerant. They are suitable for USDA Hardiness Zones 9B through 11. The trees are deciduous, shedding both leaves and flowers annually, which can create significant leaf litter. Proper pruning is essential for maintaining a strong structure, as poorly structured trees are prone to splitting. Despite their beauty, jacarandas are not ideal for pool-side plantings due to the mess from the dropped flowers and leaves​​.

The jacaranda has also been embraced in various cultures and locations worldwide, including parts of the United States like California and Florida, as well as in cities across Southern Africa and even in Europe along the Mediterranean coast. Its flowering in spring has made it a symbol of the season in many places, and it has even found its way into popular culture, being mentioned in songs and other media​​.
