From upright to creeping verbenas. You can think of bringing a dramatic twist to your landscape by using creeping varieties.

But, we know you are here for the groundcover, the “eye-catchy ones” and variety that would suit the best groundcover result. Right!?
So, let’s get started on Verbena Groundcover!
How to choose Verbena for Groundcover?
Choosing the correct species for Verbena Groundcover is the most important step here.
- Choosing the verbena variety that usually grows close to the ground, trailing types, and don’t attain much height, perhaps there are many varieties of verbena that grow as bushes of about 4-5 feet tall.
- The verbena(creeping ones) grow by vegetative propagation spreading out the stems from which roots emerge and new plants are formed.
- The upright types of the verbena propagate via rhizomes that give out the new shoots. These two spread out more, staying low to the ground, and obviously would form an outrageous groundcover.
- Make sure that the ground cover also needs proper spacing. You can play them in the triangular form groups with about a little space, approximately 12 inches gap between them. The measurements may vary depending on your space and the size of the area.
- It is important to know the square foot area of the garden to get an idea about the plant’s number. This will also reduce the chances of “mildew”(white powdery patches) on parts of verbena plants.
How do you spread Verbena?
Verbena grows well in good sunlight, well drained-moist soil but not overly watered soil type. A full day of sun exposure is important for a good verbena landscape, avoiding too much shade can let the growth cycle move unbothered. Verbena is a perennial plant and popular for the groundcovers, filling spaces, or hanging its beautiful branches with flowers in pots. To spread verbena better, trimming the plant short to one-fourth of its height can be beneficial. Make sure water reaches and spreads thoroughly to verbena. The hardiness in winter, that may appear and leads to difficulty in their survival, can be reduced by continuous pruning.
How to Grow and Care for Verbena?
As we have already made you aware of the water and soil conditions required for ‘great’ verbena groundcovers, other requirements are:
Fertilizer: Adding a layer of organic fertilizer in mid to late springtime, don’t go for too many additions of fertilizers. The continuous fertilizers in the garden beds should be done during the planting times of verbena.
Pruning and Deadheads: Deadheading is not much required in verbs to let the blooms stay healthy. The trimming will help to reduce too many elongated ends that are hindering the growth of other plants. Trimming for verbena is highly beneficial but yeah! Light trims work best!
- The verbenas, in most cases, are short surviving plants, so you wouldn’t want to keep the dead plant or flowers in the garden bed, make sure to replace the plants after two to three years. The trailing ones grow well in the garden and some can re-seed on their own, and regrow naturally.
