Devil's Backbone
Euphorbia tithymaloides
Euphorbia tithymaloides, commonly known as Devil's Backbone, is a succulent shrub characterized by its unique zig-zagging stems and fleshy, ovate leaves. It can grow up to 6-8 feet tall outdoors, but typically remains smaller when grown as a houseplant. The leaves are typically green, but variegated forms with white or pink edges are also popular. Small, slipper-shaped red or pink flowers appear sporadically. It's grown for its unusual form and ease of care, though it's important to note its toxicity.
Forget-Me-Not
Myosotis sylvatica
Myosotis sylvatica, commonly known as Forget-me-not, is a biennial or short-lived perennial plant typically grown for its delicate, vibrant blue flowers. It forms a low-growing, bushy habit, reaching heights of about 6-12 inches. The plant features small, hairy, lance-shaped leaves and clusters of tiny, five-petaled flowers with a yellow center. While primarily an outdoor plant, it is sometimes attempted indoors for its charming blooms, though success is limited due to its need for specific temperature and light conditions. People grow it for its sentimental value and the beautiful carpets of blue it creates in gardens.
