In addition to being grown for their ornamental foliage, Licorice Plants are sometimes used for their aromatic qualities.

The leaves have a mild licorice scent when crushed, hence the plant’s common name. However, this scent is not as strong as that of true licorice (Glycyrrhiza glabra).


Pansies are cool-season annuals, meaning they thrive in cooler temperatures, making them ideal for window boxes in spring and fall. They can withstand light frost, allowing you to enjoy their blooms even as temperatures begin to drop.

Pansies are known for their distinctive “faces,” characterized by two upper petals overlapping two lower petals, resembling a smiling face.

These petals come in many amazing colors, including shades of purple, yellow, orange, blue, red, white, and bi-color combinations. Some pansy varieties also feature contrasting blotches or dark markings on their petals.

Pansies are available in a wide range of varieties, including large-flowered pansies, miniature or multiflora pansies, and trailing pansies. Large-flowered varieties are known for their showy blooms, while miniature pansies are more compact and suitable for smaller spaces.

Dwarf Marigolds

Both the flowers and leaves of nasturtiums are edible, adding a unique flavor to salads and other dishes. This dual-purpose makes them not only visually appealing but also functional.
