Tradescantia virginiana and Tradescantia ohiensis are two species of plants that belong to the genus Tradescantia. While they may share some similarities, there are several key differences between the two.
1. Appearance and Growth Habit: Tradescantia ohiensis tends to be taller and more spindly in growth compared to Tradescantia virginiana. The stems of T. ohiensis can reach heights of up to 3 feet, while T. virginiana typically stays around 1-2 feet tall. This difference in height can be significant when planning a garden or landscape design, as taller plants may be better suited for certain areas.
2. Tolerance to Sunlight: Tradescantia ohiensis is known to be more tolerant of hot, sunny sites compared to T. virginiana. This makes it a great choice for gardens or landscapes with full sun exposure. On the other hand, T. virginiana may prefer some shade or partial sun, as it can be more susceptible to heat stress.
3. Leaf Color and Texture: While both species have narrow, lance-shaped leaves, there is a slight difference in color and texture. T. ohiensis leaves have a grayish-blue tinge, giving them a unique appearance. In contrast, T. virginiana leaves are typically green in color. Additionally, T. ohiensis leaves may have less pubescence (fine hairs) on the sepals compared to T. virginiana.
4. Geographic Distribution: Tradescantia ohiensis is native to the central and eastern regions of the United States, including parts of Ohio, Indiana, and Kentucky. On the other hand, Tradescantia virginiana has a broader distribution and can be found in various parts of North America, including the eastern and central regions as well as parts of Canada.
In my personal experience, I have found Tradescantia ohiensis to be a great addition to sunny garden beds. Its tall and slender growth habit adds vertical interest to the landscape, while its tolerance to heat and sun makes it a reliable choice for hot summer climates. On the other hand, Tradescantia virginiana can be a lovely addition to shadier areas, where its green leaves provide a vibrant pop of color.
To summarize, the main differences between Tradescantia virginiana and Tradescantia ohiensis lie in their appearance, growth habit, tolerance to sunlight, leaf color and texture, and geographic distribution. By understanding these differences, gardeners and landscapers can make informed decisions about which species to choose for their specific needs and preferences.
