Phlox Paniculata
Phlox paniculata
Phlox paniculata, commonly known as Garden Phlox, is a herbaceous perennial prized for its vibrant, fragrant flowers. It typically grows to a height of 2-4 feet with an upright, clump-forming habit. The lance-shaped leaves are arranged oppositely along the stems. Native to moist meadows and woodlands, Garden Phlox is primarily an outdoor plant, cultivated for its showy blooms in shades of pink, purple, white, red, and orange. While technically possible to grow indoors, it's challenging to provide the necessary light and air circulation for optimal health and flowering.
Queen's Tears
Billbergia nutans
Billbergia nutans, commonly known as Queen's Tears, is an epiphytic bromeliad characterized by its arching, grass-like foliage and striking, pendulous inflorescence. The plant features tubular, metallic green leaves that form a vase-like rosette. It is primarily grown for its unique flowers, which consist of pink bracts and iridescent blue-green petals tipped with purple. While adaptable to indoor conditions, it thrives best with bright, indirect light and good air circulation. People grow it for its unusual blooms and relatively easy care.
