How to tell the difference between morning glory and bindweed?

When it comes to distinguishing between bindweed and morning glory, there are a few key factors to consider. Let’s delve into the various characteristics of these plants to help you tell them apart.

1. Leaf Shape and Size:
Bindweed leaves are arrow-shaped, slender, and smaller compared to the leaves of annual morning glory. The leaves of morning glory are generally larger and heart-shaped, providing a fuller appearance. By examining the shape and size of the leaves, you can easily differentiate between the two plants.

2. Flower Appearance:
Another distinguishing feature is the appearance of their flowers. Bindweed flowers are typically white or pink and measure around 1 inch in diameter. On the other hand, morning glory flowers come in a variety of colors and can be much larger, ranging from 2 to 6 inches in diameter, depending on the cultivar. The vibrant and larger flowers of morning glory are often a highlight in gardens and landscapes.

3. Growing Habit:
Bindweed and morning glory also differ in their growing habits. Bindweed is a perennial vine that can be invasive and difficult to control. It twines around other plants and structures, often causing damage. Morning glory, on the other hand, is an annual vine that grows from seed each year. While it can still be vigorous and spread, it is generally easier to manage compared to bindweed.

4. Weed-Like Characteristics:
Bindweed is often considered a weed due to its invasive nature and ability to rapidly spread. It can quickly take over gardens and landscapes if not controlled. In contrast, morning glory is cultivated as an ornamental plant and is intentionally planted in many gardens for its attractive flowers and lush foliage. However, it’s important to note that certain cultivars of morning glory can also have invasive tendencies in some regions.

5. Cultivation and Control:
If you find bindweed or morning glory growing in your garden, it’s essential to take appropriate action to manage them effectively. For bindweed, manual removal can be challenging, as it has an extensive root system that can regrow from even small fragments. Persistent digging and the use of herbicides specifically designed for bindweed control may be necessary. Morning glory is typically easier to manage, and regular weeding and cutting back can help prevent it from spreading excessively.

In my personal experience as a gardener, I have encountered both bindweed and morning glory in various landscapes. The distinct leaf shapes and flower sizes have always been my go-to method for identification. Additionally, observing the growth habit and considering the plant’s behavior in the garden can also provide valuable clues.

To summarize, differentiating between bindweed and morning glory involves examining leaf shape and size, flower appearance, growth habit, and considering their weed-like characteristics. By paying attention to these factors, you can confidently identify these plants and implement appropriate management strategies in your garden or landscape.
