1. Common Ivy

Also known as English ivy, this plant is a good cover for walls and similar structures. The ivy likes shady to full sun exposure. It grows slowly but reaches up to 50 feet. As super climbers, they are low-maintenance as long as the soil is moist.

However, the common ivy is a notorious weed. The plant is a threat where there is vegetation. As they climb, tree trunks, branches, and twigs get enveloped by the vines.

As a result, the ivy prevents sunlight from reaching the tree's foliage. After many years, the tree will die. You should refer to your state regulations before you plant outdoors.

2. Creeping Phlox

This plant is native to North American mountains. The phlox is an attractive groundcover growing well in full sun on moist, well-drained soil. Once it has matured, it becomes drought-tolerant.  

Although it naturally spreads horizontally, you can place it in hanging pots, so the colorful flowers overflow on the rims.

When growing on pots, here are the steps:

  1. Grow the phlox seeds indoors at least 6 weeks before the last frost. You can also buy them from a local plant nursery to start with the small plant.
  2. After the frost, transplant it to a pot with a good potting mix. Make sure that the pot has a draining hole.
  3. Do not overcrowd the plant to allow it to sprawl. Leave around 6 inches between each plant.
  4. Water the plant immediately after planting.

Avoid watering too much to prevent rot. Cutting the plant back also helps to encourage more blooms.
