38.Creeping Thyme
Creeping Thyme is another excellent ground cover, with its flexibility and delicate elegance. Creeping Thyme is a hardy perennial that has a trailing, horizontally vining habit similar to mint. It can easily cover large areas and is simple to start from seed over large areas.
It has many purple flowers, which make a lovely backdrop for any other flowers it grows near. While it cannot tolerate full shade, it can cover a wide range of other difficult-to-cover areas. This is the flower for you if you like the color magenta.
39.Giant Allium
Look no further than the Giant Allium if you are looking for a show-stopper with remarkably long-lasting flowers. It is related to garlic, onion, and other Allium family members, as the Allium part of its name implies, and its flowers represent that relationship.
It appears early in the spring and rapidly fills its growing area with bright green leaves that resemble tulip greens. Depending on the season, the flowers will last for several weeks and are extremely attractive. It rewards gardeners with big globes covered in tiny purple flowers at the top of long, thick stems in the early summer.
