What is the difference between Camellia japonica and Camellia Williamsii?

Camellia japonica and Camellia Williamsii are two popular species of camellia plants. While they share some similarities, there are several key differences between them.

1. Hardiness: One of the main advantages of Camellia Williamsii over Camellia japonica is its hardiness. Williamsii varieties are fully hardy in almost all parts of the UK, making them suitable for growing in cooler areas. On the other hand, Camellia japonica may struggle in colder climates and is more suited to milder regions.

2. Flowering Period: Another notable difference is the flowering period. Camellia Williamsii plants produce flowers over a longer period, typically from mid-March to late April. This extended bloom time allows for a more prolonged display of beautiful blossoms. In contrast, Camellia japonica tends to have a shorter flowering period, usually from late winter to early spring.

3. Flower Form: Camellia Williamsii and Camellia japonica also differ in their flower forms. The flowers of Camellia japonica are usually large and showy, with ruffled petals and a prominent central cluster of stamens. They come in a wide range of colors, including white, pink, red, and variegated varieties.

On the other hand, Camellia Williamsii flowers are generally smaller and more delicate, with a single row of petals surrounding a cluster of stamens. They often have a simpler, more elegant appearance. Williamsii varieties also offer a diverse color range, including shades of pink, red, and white.

4. Leaf Characteristics: While both species have evergreen foliage, there are slight differences in their leaf characteristics. Camellia japonica has glossy, dark green leaves that are typically oval or lance-shaped. In contrast, Camellia Williamsii leaves are often broader and have a lighter green color.

5. Hybrid Origins: Camellia Williamsii is actually a hybrid between Camellia japonica and Camellia saluenensis, a species native to China. This hybridization has resulted in a plant that combines the best traits of both parent species, including hardiness, extended flowering period, and attractive flowers.

In my personal experience as a gardener, I have found Camellia Williamsii to be a versatile and reliable plant. Its ability to withstand colder climates makes it a great choice for those living in cooler regions. The extended blooming period also adds interest to the garden for a longer period of time. The delicate and elegant flowers of Williamsii varieties can create a stunning display, and their diverse colors offer plenty of options for garden design.

While Camellia japonica has its own appeal with its showy flowers, Camellia Williamsii has the advantage of hardiness, extended flowering period, and a wide range of attractive flower colors. Consider your climate and desired flowering period when choosing between these two camellia species for your garden.
