Thryallis plants are indeed considered medium to fast-growing shrubs. In their first season, they have the potential to grow as much as 4 feet (1.2 meters), which is quite impressive. However, it’s important to note that the growth rate may vary depending on various factors such as environmental conditions, soil quality, and overall care.
To ensure optimal growth, Thryallis plants should ideally be grown in a sunny and sheltered space. They thrive in full sunlight and require at least six hours of direct sunlight per day. This abundant sunshine helps them develop sturdy and healthy stems, as well as promote flower production.
While Thryallis plants may tolerate some shade, it’s important to understand that reduced sunshine will have an impact on their overall growth and flower production. In shadier conditions, the plant may become more spindly and have a thinner body. This can result in a less desirable appearance and potentially fewer blooms.
In my personal experience, I have seen Thryallis plants thrive when grown in a sunny location with well-draining soil. I have observed that they tend to grow more vigorously and produce an abundance of vibrant flowers when provided with ample sunlight. When grown in a partially shaded area, the growth rate tends to slow down, and the plant may appear less robust.
To summarize, Thryallis plants are considered fast-growing shrubs, especially in their initial season. However, providing them with sufficient sunlight is crucial for optimal growth and abundant flower production. While they may tolerate some shade, it’s best to provide them with as much direct sunlight as possible to ensure a healthy and vigorous plant.
