Cup and Saucer Vine

Cobaea scandens

Cobaea scandens, commonly known as the Cup and Saucer Vine, is a vigorous, fast-growing perennial climber typically grown as an annual in temperate climates. It features distinctive cup-shaped flowers (the 'cup') sitting atop a saucer-like calyx. The flowers start as greenish-white and mature to a rich purple, attracting pollinators like bees and hummingbirds. It's primarily an outdoor plant, prized for its rapid growth and ability to cover fences, walls, and trellises quickly. While some attempt to grow it indoors, it requires very bright light and significant space, making it challenging.

Mandarin Orange

Mandarin Orange

Citrus reticulata

The Mandarin orange is a small, evergreen tree typically reaching 2-8 meters in height. It's known for its easily peeled fruit with a sweet, slightly tart flavor. While primarily an outdoor tree cultivated for commercial fruit production, it can be grown in containers indoors with significant effort. People grow Mandarin oranges for their delicious fruit, ornamental value (fragrant blossoms and attractive foliage), and as a symbol of good fortune in some cultures. Indoor cultivation is challenging due to high light and humidity requirements.
