Also Known As Garden Phlox, Summer Phlox, Perennial Phlox
Leaves Oppositely arranged, lance-shaped leaves that are typically 2-6 inches long and 1-2 inches wide. The leaves are medium green and have a slightly rough texture.
Flowers Flowers profusely outdoors in summer. Individual flowers are small, about 1 inch in diameter, but are borne in large, showy clusters (panicles) at the top of the stems. Flowers come in a wide range of colors, including pink, purple, white, red, and orange. Rarely flowers indoors due to insufficient light.

Rainbow Chard

Scientific Name Beta vulgaris subsp. cicla
Family Amaranthaceae
Native To Mediterranean region
Also Known As Rainbow Chard, Swiss Chard, Silverbeet
Leaves The leaves are large, typically 15-30 cm long and 10-20 cm wide, with a crinkled or puckered texture. They are dark green in color, contrasting with the brightly colored stalks and veins, which can be red, orange, yellow, pink, or white.
Flowers Rainbow chard may produce flowers if it bolts (prematurely flowers), especially in hot weather. The flowers are small, greenish, and arranged in clusters. Flowering typically makes the leaves less palatable, so it's best to harvest before bolting occurs. It rarely flowers indoors.

  • Provide good air circulation to prevent powdery mildew.
  • Deadhead spent flowers regularly to encourage more blooms.
  • Water deeply at the base of the plant to avoid wetting the foliage.
  • Divide plants every few years to maintain vigor.
  • Choose disease-resistant varieties to minimize problems.
❄️ Winter: Cut back stems to the ground after the foliage dies back in late fall. Provide a layer of mulch around the base of the plant to protect the roots from freezing temperatures. Reduce watering significantly during winter dormancy.
☀️ Summer: Water deeply and regularly during hot, dry weather. Deadhead spent flowers to encourage continuous blooming. Provide support for taller varieties to prevent them from flopping over. Monitor for pests and diseases and treat as needed.

Rainbow Chard Care Tips

Rainbow chard is primarily an outdoor plant. Growing it indoors is challenging due to its high light requirements and need for consistent moisture. It requires full sun and well-draining soil. Indoor plants are unlikely to thrive and may not exhibit the vibrant colors seen in outdoor-grown chard.
