Dieffenbachia
Dieffenbachia seguine
Dieffenbachia seguine, commonly known as Dumb Cane, is a popular ornamental plant prized for its large, decorative leaves. It's a herbaceous perennial that typically grows upright with a thick, cane-like stem. The leaves are broad, ovate, and variegated with patterns of green, cream, yellow, or white. While it can grow outdoors in tropical climates, it's primarily cultivated as a houseplant for its attractive foliage. People grow it for its ease of care and ability to brighten indoor spaces, although its toxicity requires caution.
Mum
Chrysanthemum × morifolium
Chrysanthemum × morifolium, commonly known as mums, are popular flowering plants cultivated for their vibrant and diverse flower colors and forms. They are herbaceous perennials, typically grown as annuals in many climates due to their sensitivity to frost. Mums are characterized by their bushy growth habit and composite flower heads, which come in various shapes like daisy-like, pompon, and spider. While primarily outdoor plants, they are often brought indoors for short periods to enjoy their blooms, but they require specific conditions to thrive indoors long-term. People grow them for ornamental purposes, adding color to gardens and homes, and for cut flowers.
