Bells of Ireland is an annual flowering plant known for its tall spikes of vibrant green, bell-shaped calyces (modified leaves) that surround tiny, inconspicuous white flowers. It typically grows to a height of 2-3 feet. While it can be grown indoors, it's primarily an outdoor plant, often cultivated in gardens for its unique architectural form and long-lasting cut flowers. People grow it for its ornamental value, particularly in floral arrangements, where its bright green color adds a striking contrast.
Musk Mallow
Malva moschata
Musk Mallow is a herbaceous perennial plant known for its delicate, musky fragrance, though this is often faint or absent. It typically grows to a height of 30-80 cm (1-2.5 feet). The plant features deeply divided, palmate leaves and produces attractive, five-petaled flowers that are usually pink or white. It is primarily an outdoor plant, favored in cottage gardens and wildflower meadows for its charming appearance and ability to attract pollinators. While it can be grown in containers, it is not ideally suited for indoor environments due to its need for ample sunlight and space.
