Blue Ginger vs Cedar Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Blue Ginger
Dichorisandra thyrsiflora
Dichorisandra thyrsiflora, commonly known as Blue Ginger, is a striking tropical perennial native to Brazil. Despite its common name, it is not a true ginger. It features upright, cane-like stems adorned with glossy, dark green leaves. The plant is prized for its vibrant, cobalt-blue flowers that bloom in dense, terminal clusters (thyrses), typically in late summer or fall. It is primarily grown outdoors in warm climates as an ornamental plant, adding a splash of color to gardens and landscapes. While it can be grown indoors, it requires very bright light and high humidity to thrive and flower successfully.
Cedar
Cedrus spp.
Cedrus species, commonly known as true cedars, are coniferous evergreen trees characterized by their aromatic wood, needle-like leaves arranged in spirals on long shoots and in dense clusters on short shoots, and barrel-shaped cones. They are large trees, typically reaching heights of 30-40 meters (100-130 feet) or more in their native habitats. Cedars are primarily outdoor trees, valued for their majestic appearance and use in landscaping. They are not naturally indoor plants and struggle to thrive in the confined conditions of indoor environments. People grow them for ornamental purposes, timber production, and their cultural significance.

❓ Frequently Asked Questions — Comparing These Plants
Blue Ginger
What are the light requirements for Blue Ginger?
Blue Ginger requires bright, indirect light to thrive and produce its vibrant blue bracts. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves. An east-facing window is ideal, providing gentle morning light. A north-facing window can also work if the light is bright enough. If you’re using a south- or west-facing window, filter the light with a sheer curtain. Insufficient light will result in leggy growth, reduced flowering, and dull foliage. Rotate the plant regularly to ensure even light exposure on all sides. Artificial grow lights can supplement natural light, especially during winter months.
How do I care for Blue Ginger?
Blue Ginger thrives in bright, indirect light. Direct sunlight can scorch its leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain high humidity levels, ideally above 60%, through misting, a humidifier, or pebble tray. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Reduce watering and fertilization in fall and winter. Repot every 1-2 years in spring, using a well-draining potting mix. Prune spent flower stalks to encourage new growth. Maintain temperatures between 65-80°F (18-27°C). Protect from drafts and sudden temperature changes. Monitor for pests like spider mites and mealybugs and treat promptly. Provide support for taller stems as needed. Ensure adequate air circulation.
How do I propagate Blue Ginger?
Blue Ginger can be propagated through division, stem cuttings, or keiki (offsets).
Cedar
What are the light requirements for Cedar?
Indoor cedars thrive in bright, indirect light. Placing them near an east- or west-facing window is usually ideal. Avoid direct sunlight, especially during the hottest part of the day, as it can burn the delicate needles. Insufficient light can lead to leggy growth and yellowing foliage. If you don’t have access to sufficient natural light, consider supplementing with a grow light. Rotate your cedar regularly to ensure all sides receive adequate light. During the winter months, when sunlight is less intense, you may need to move your cedar closer to a window or increase the amount of supplemental light. Pay close attention to the plant’s growth and adjust its position accordingly.
How do I care for Cedar?
Indoor cedar trees require bright, indirect light; avoid direct sunlight, which can scorch the foliage. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix formulated for conifers or evergreens. Maintain moderate humidity, especially during dry winter months. Fertilize sparingly, only during the growing season (spring and summer), with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain the desired shape and remove any dead or yellowing foliage. Repot every 2-3 years, or when the plant becomes root-bound, into a slightly larger pot. Ensure adequate air circulation to prevent fungal diseases. Monitor for pests such as spider mites or scale and treat promptly. Provide stable temperatures, avoiding drastic fluctuations. Rotate the plant regularly to ensure even growth on all sides.
How do I propagate Cedar?
Cedar can be propagated through stem cuttings or air layering. For stem cuttings, take 4-6 inch cuttings from new growth in spring or early summer. Remove the lower needles and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist and humid. Rooting can take several weeks to months. For air layering, make a small incision in a branch, apply rooting hormone, and wrap the incision with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots have formed, cut the branch below the roots and pot it up. Both methods require patience and careful monitoring. Maintain consistent moisture and humidity for successful propagation. Choose healthy, vigorous branches for the best results.
