Jupiter's Beard
Centranthus ruber
Centranthus ruber, commonly known as Jupiter's Beard, is a perennial plant typically grown outdoors for its vibrant clusters of small, star-shaped flowers. It forms a bushy clump of grey-green leaves and can reach up to 3 feet in height. The flowers are most commonly a deep rose-red, but can also be white or pink. While visually appealing, it is primarily an outdoor plant and may struggle to thrive indoors due to its high light requirements and potential for aggressive spreading via self-seeding.
Polyscias
Polyscias fruticosa
Polyscias fruticosa, commonly known as Ming Aralia, is an evergreen shrub or small tree prized for its intricately divided, fern-like foliage. It typically grows to 1-2 meters indoors, but can reach greater heights outdoors. The plant features woody stems and a dense canopy of small, rounded leaflets. It is primarily grown for its ornamental foliage, adding a touch of elegance and texture to indoor spaces. While it can be grown indoors, it requires specific conditions to thrive and is often considered a more challenging houseplant. Its unique appearance makes it a popular choice for bonsai enthusiasts.
