Canna indica

Canna indica, commonly known as Canna lily, is a rhizomatous perennial with large, paddle-shaped leaves and showy flowers. It's primarily grown outdoors for its tropical appearance and vibrant blooms, which come in various colors like red, orange, yellow, and pink. The plant grows from rhizomes, spreading readily in suitable conditions. While it can be grown indoors, it requires very bright light and ample space to thrive, making it more challenging than typical houseplants. People grow them for their bold foliage and exotic-looking flowers.

Madder

Rubia tinctorum

Rubia tinctorum, or Madder, is a herbaceous perennial vine primarily cultivated for its roots, which yield a natural red dye. It features sprawling stems that can grow several feet long, adorned with lance-shaped, rough-textured leaves arranged in whorls around the stem. Small, yellowish-green flowers appear in clusters during the summer. While it can be grown in gardens, it's not typically suited for indoor cultivation due to its vining habit and need for ample sunlight. People grow it mainly for dye production and historical interest.

💡 Pro Tips For Comparing These Plants

Canna Lily Care Tips

Canna lilies are primarily outdoor plants that require full sun and ample moisture. Growing them indoors is challenging due to their high light requirements and potential for aggressive rhizome spread. They need large pots and frequent fertilization to thrive indoors. Expect less flowering indoors.

  • Provide ample sunlight – at least 6 hours of direct sun is crucial for flowering.
  • Water deeply and regularly during the growing season, but avoid soggy soil.
  • Fertilize every 2-4 weeks with a balanced liquid fertilizer to promote healthy growth and flowering.
  • Protect from strong winds, which can damage the large leaves.
  • Overwinter rhizomes indoors in colder climates by storing them in a cool, dry place.
❄️ Winter: In colder climates, Canna lilies are not winter hardy. After the first frost, cut back the foliage and dig up the rhizomes. Store them in a cool, dry place (around 4-10°C) in peat moss or vermiculite until spring.
☀️ Summer: Provide ample water and fertilizer during the growing season. Protect from strong winds. Deadhead spent flowers to encourage continued blooming. Monitor for pests and diseases.

Madder Care Tips

Madder is primarily an outdoor plant and requires full sun and well-draining soil. It can be challenging to grow indoors due to its need for intense light and its spreading habit. It is toxic to pets. Regular monitoring for pests and diseases is necessary.

  • Provide a trellis or support for the vines to climb.
  • Monitor regularly for pests and diseases.
  • Harvest roots in the fall after the plant has matured for at least two years.
  • Wear gloves when handling the plant, as some individuals may experience skin irritation.
  • Control its spread by containing the rhizomes.
❄️ Winter: In colder climates, the plant may die back to the ground. Protect the roots with a layer of mulch to prevent frost damage. Reduce watering during dormancy.
☀️ Summer: Ensure adequate watering during hot, dry periods. Monitor for pests and diseases, and provide support for the vines to climb. Fertilize lightly in early summer.
