Bletilla, also known as the Chinese ground orchid, is a popular choice for gardeners and landscapers due to its beautiful and unique flowers. There are several different types of Bletilla that are commonly cultivated, each with its own characteristics and growing requirements.
1. Bletilla striata: This is the most commonly grown species of Bletilla. It is known for its hardiness and ability to tolerate a wide range of growing conditions. The flowers of Bletilla striata are typically pink or lavender in color, with a lip that has purple markings. This species is native to China, Japan, and Taiwan.
2. Bletilla ochracea: This species of Bletilla is less hardy than Bletilla striata and requires slightly more care. It is native to southeastern China and has yellow or orange flowers. Bletilla ochracea prefers slightly warmer temperatures and may not be suitable for colder climates.
3. Bletilla formosana: Another commonly cultivated species, Bletilla formosana is native to Taiwan and has a more compact growth habit compared to Bletilla striata. The flowers of Bletilla formosana can range from white to pale pink and have a delicate fragrance.
4. Hybrids: There are also hybrids available that are a cross between different species of Bletilla. These hybrids often combine the best traits of their parent plants, such as hardiness, flower color, and growth habit. They can come in a wide range of colors, including shades of pink, purple, and white.
When choosing a type of Bletilla to grow, it is important to consider the climate and growing conditions of your area. Bletilla striata is generally the most reliable and adaptable species, making it a good choice for beginners or those with less ideal growing conditions. However, if you live in a warmer climate or prefer a specific flower color, you may opt for Bletilla ochracea, Bletilla formosana, or a hybrid variety.
In my personal experience, I have grown Bletilla striata in my garden and found it to be a resilient and beautiful plant. The flowers bloom in late spring or early summer and can last for several weeks, providing a burst of color in the garden. I have also seen Bletilla ochracea and Bletilla formosana grown in botanical gardens and was impressed by their unique flower colors and delicate appearance.
The different types of Bletilla offer a range of options for gardeners and landscapers looking to incorporate these beautiful orchids into their outdoor spaces. Whether you choose Bletilla striata for its hardiness, Bletilla ochracea for its vibrant yellow flowers, Bletilla formosana for its compact growth habit, or a hybrid variety for a combination of traits, you are sure to be rewarded with stunning blooms and a touch of elegance in your garden.
