Norfolk Island Pine
Araucaria heterophylla
The Norfolk Island Pine is a coniferous evergreen tree characterized by its symmetrical, pyramidal shape and soft, needle-like foliage. While it can reach towering heights of up to 200 feet in its native habitat, it remains significantly smaller when grown indoors, typically reaching 3-8 feet. It is often grown as a decorative indoor plant, especially during the holiday season, due to its resemblance to a miniature Christmas tree. It is not a true pine, but belongs to the Araucariaceae family. People grow it for its unique architectural form and its ability to tolerate indoor conditions better than many other conifers.
Sweet Pea
Lathyrus odoratus
Sweet peas are annual climbing plants, known for their beautiful, fragrant flowers. They are not naturally indoor plants and are typically grown outdoors in gardens. They feature delicate, papery petals in a wide range of colors, including pink, purple, red, white, and bi-colors. Sweet peas climb using tendrils, reaching heights of 1 to 2 meters. People grow them for their ornamental value, the delightful fragrance of their blooms, and their use as cut flowers.
