Cherry blossoms are celebrated for their ephemeral beauty, typically seen in soft pink and pure white petals. However, a lesser-known, yet equally captivating, segment of these trees displays blossoms in shades of yellow. These unique yellow varieties offer a distinctive visual appeal, providing an unexpected twist to the traditional cherry blossom spectacle. They highlight the diverse range within the cherry blossom family.
The Nature of Yellow Cherry Blossoms
Yellow cherry blossoms exist, offering a unique coloration. Their greenish-yellow tones are often attributed to specific pigment compounds like carotenoids and flavonols, and sometimes chloroplasts within the petals. These blossoms are considerably less common than pink and white varieties, making them a distinctive and sought-after sight, and their rarity adds to their allure.
Prominent Yellow Cherry Blossom Varieties
Among the most well-known yellow cherry blossom cultivars are ‘Ukon’ and ‘Gyoiko’, both originating from Japan. Prunus serrulata ‘Ukon’ has semi-double flowers that emerge greenish-yellow, gradually transitioning to a creamy yellow hue. As the blooms mature, their centers often develop a delicate pink tint. This variety typically blooms in late April to early May, with its new coppery-bronze foliage providing a striking contrast.
Prunus serrulata ‘Gyoiko’ offers a distinct display. Its double-petaled flowers often feature a unique blend of white and light green, sometimes infused with pink shades. The green coloration in ‘Gyoiko’ flowers is attributed to chloroplasts. As these blossoms age, a red stripe can become more pronounced in their centers. ‘Gyoiko’ tends to bloom slightly later than other popular varieties, offering its distinct palette in mid-spring.
Growing Yellow Cherry Blossoms
Cultivating yellow cherry blossoms generally follows the same principles as growing other Prunus serrulata varieties. These trees thrive in full sun. They prefer well-drained, fertile soil that is slightly acidic, though they can tolerate a range of soil pH levels. Consistent moisture is beneficial, requiring regular watering, but allowing the soil to dry partially between waterings helps prevent root issues.
Yellow cherry blossoms are hardy in USDA zones 5 through 8, indicating their adaptability to temperate climates. Providing good air circulation helps mitigate the risk of common cherry tree diseases. Minimal pruning is typically required, mainly for removing dead or damaged branches, as they generally flourish when left undisturbed.
Notable Locations for Yellow Cherry Blossoms
To witness the unusual beauty of yellow cherry blossoms, certain locations host these unique varieties. In Japan, Tokyo’s Shinjuku Gyoen National Garden is a notable place to observe ‘Ukon’ cherry blossoms. While many gardens worldwide feature diverse cherry blossom collections, specific yellow varieties like ‘Ukon’ and ‘Gyoiko’ are more specialized. Gardens focusing on a wide array of cherry cultivars, especially those with extensive Japanese collections, may also feature these yellow blooms.
