Currently, the jellyfish plants commonly found on the seedling market in China are primarily from the genus *Malus*, which belongs to the Rosaceae family. There are around 35 species of this genus worldwide, distributed across Asia, Europe, and North America. China is considered the center of diversity for *Malus*, with approximately 25 native species. Internationally, cultivars within this genus are typically divided into two categories based on fruit size: apples and jellyfish. Jellyfish refers to varieties with fruits smaller than 5 centimeters in diameter, often used for urban landscaping and beautification. These are commonly referred to as modern jellyfish. Different varieties of modern jellyfish can be adapted to various garden settings. Some are ideal for solitary planting, while others thrive when grouped together. Some are suitable as street trees, and a few even produce fruit during the winter months. Since the 1990s, China has introduced numerous modern jellyfish varieties, leading to widespread propagation and use in cities such as Shenyang, Xining, Qiqihar, Urumqi, Qingdao, and Jinan. Below are some of the popular varieties currently available. '**Malus Dolgo**' grows to a height of 10–12 meters with a crown width of 8–10 meters. It has yellow-green bark, white flowers, and bright red fruits measuring about 3.5 cm in diameter. It blooms in mid-April and ripens in July, shedding its leaves in November. This variety is known for its early flowering and cold tolerance, though it is less commonly used in large-scale projects due to limited availability. '**Flam**' (also known as *Malus Flame*) reaches a height of 4.5–6 meters with a crown width of 4.5 meters. It features yellow-green bark, white flowers, and dark red fruits that are about 2 cm in diameter. It blooms in late April and fruits mature by August. The fruit persists on the tree for a long time, making it well-suited for northern regions. It is cold-hardy and widely used in landscaping projects. '**Malus Jewelberry**' is a compact variety, growing to about 3 meters tall with a crown of 3.5 meters. Its bark has a brownish-red color, and it produces pink flower buds that open to white. The fruit is bright red and only 1 cm in diameter. It blooms in late April, and the fruit remains on the tree through the season. While it has a long fruiting period, it is not widely available as seedlings. '**Malus Red Splendor**' reaches a height of 6–7.5 meters with a crown of 6 meters. It has pink flowers and bright red fruits measuring 1.2 cm in diameter. It blooms in late April, and the fruit ripens from August to October. This hybrid between apple and *Shandongzi* exhibits strong disease resistance and vibrant flowering. It is commonly used in engineering projects and is more readily available. '**Malus Royalty**' is a tree-shaped variety, reaching 4.5–5.5 meters in height with a crown of 6 meters. It has dark purple flowers and deep purple fruits that are 1.5 cm in diameter. It blooms in late April, and the fruit ripens from June to October. This variety is known for its striking purple foliage and is widely cultivated, although it is less commonly found as seedlings.
