Amaranth vs Pineapple Sage Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Amaranth
Amaranthus spp.
Amaranth is a genus of annual or short-lived perennial plants known for their vibrant foliage and grain-like seeds. They vary greatly in appearance, from upright, bushy forms to drooping, tassel-like inflorescences. Many species are cultivated for their edible leaves and seeds, which are highly nutritious. Others are grown as ornamentals for their colorful foliage, which can range from green to red, purple, and gold. Amaranth is primarily an outdoor plant, thriving in full sun and warm temperatures. While some smaller varieties might temporarily survive indoors, they will struggle to achieve their full potential.
Pineapple Sage
Salvia elegans
Pineapple Sage is a perennial shrub known for its fragrant leaves that emit a distinct pineapple scent when crushed. It typically grows to a height of 3-5 feet outdoors. It features vibrant green, ovate leaves and produces bright red, tubular flowers in the late summer and fall. While primarily an outdoor plant, it is grown for its aromatic foliage and edible flowers, which add a unique flavor to culinary dishes and attract pollinators like hummingbirds and butterflies. It is not naturally an indoor plant and requires specific conditions to thrive indoors.

❓ Frequently Asked Questions — Comparing These Plants
Amaranth
What are the light requirements for Amaranth?
Amaranth demands ample sunlight to thrive and produce its characteristic vibrant blooms. Aim for at least 6-8 hours of direct sunlight daily. Inadequate light can result in leggy growth, faded colors, and reduced flowering. When grown indoors, place Amaranth near a south-facing window where it can receive maximum sunlight exposure. If natural light is insufficient, supplement with grow lights to ensure optimal growth. Rotate the plant regularly to ensure even light exposure on all sides. Be mindful of intense afternoon sun, which can scorch leaves, especially in hot climates. Consider using sheer curtains to filter the light during peak hours. Monitor the plant closely for signs of light stress, such as pale leaves or elongated stems, and adjust its position accordingly.
How do I care for Amaranth?
Amaranth thrives in full sun and well-draining soil. Water regularly, especially during hot weather, keeping the soil consistently moist but not waterlogged. Fertilize every 4-6 weeks during the growing season with a balanced fertilizer to promote healthy growth and vibrant blooms. Deadhead spent flowers to encourage further blooming. Amaranth is relatively low-maintenance, but monitoring for pests and diseases is essential. Provide support for taller varieties to prevent them from bending or breaking. Ensure good air circulation to minimize the risk of fungal issues. Prune as needed to maintain shape and remove any dead or damaged foliage. Consider mulching around the base of the plant to retain moisture and suppress weeds. Regularly inspect the plant for signs of nutrient deficiencies, such as yellowing leaves, and adjust fertilization accordingly.
How do I propagate Amaranth?
Amaranth is primarily propagated from seeds, which are readily available. Sow seeds directly into the garden after the last frost or start them indoors 6-8 weeks beforehand. For direct sowing, scatter seeds thinly over prepared soil and lightly cover with soil. Keep the soil consistently moist until germination, which typically occurs within 7-14 days. Thin seedlings to allow for adequate spacing. Amaranth can also be propagated via stem cuttings, although this method is less common. Take 4-6 inch cuttings from healthy stems, remove the lower leaves, and place them in water or directly into moist potting mix. Rooting should occur within a few weeks. Division is not a common propagation method for Amaranth. Keiki propagation is not applicable to Amaranth.
Pineapple Sage
What are the light requirements for Pineapple Sage?
Pineapple Sage needs a significant amount of sunlight to thrive and produce its characteristic vibrant red flowers. Ideally, it should receive at least 6 hours of direct sunlight each day. When grown indoors, place it near a south-facing window where it can soak up the most sunlight. If you don’t have a sufficiently sunny window, consider supplementing with grow lights.
How do I care for Pineapple Sage?
Pineapple Sage thrives in well-draining soil and requires full sun (at least 6 hours per day). Water thoroughly when the top inch of soil feels dry, but avoid overwatering. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer, switching to a bloom-boosting formula as flowering approaches. Prune regularly to maintain shape and encourage bushier growth, removing any dead or yellowing leaves.
How do I propagate Pineapple Sage?
Pineapple Sage can be easily propagated through stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant it in a pot filled with well-draining potting mix. Keep the soil moist and provide bright, indirect light. Roots should develop in 2-4 weeks.
