Hummingbird Mint vs Living Stone Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Hummingbird Mint
Agastache spp.
Agastache, commonly known as Hummingbird Mint, is a genus of herbaceous perennial plants known for their aromatic foliage and vibrant, nectar-rich flowers. They typically grow between 1 to 5 feet tall, forming bushy clumps. The leaves are usually lance-shaped and toothed. The flowers, which bloom from summer to fall, come in a variety of colors, including purple, pink, orange, and red. Agastache is primarily an outdoor plant, valued for attracting pollinators like hummingbirds and bees to gardens. People grow it for its ornamental value, drought tolerance, and fragrant foliage.
Living Stone
Lithops spp.
Lithops are fascinating succulent plants that mimic the appearance of pebbles or stones in their native arid environments. They consist of one or more pairs of nearly fused, fleshy leaves that are mostly buried beneath the soil surface, with only the top surface exposed. These surfaces are often patterned with fissures, spots, and lines, providing camouflage. Lithops are grown for their unique appearance and ability to thrive in extremely dry conditions. They are primarily outdoor plants but can be grown indoors with very specific care.

💧 Watering Needs
Hummingbird Mint
Water thoroughly when the top inch of soil feels dry. Avoid overwatering, as this can lead to root rot. Signs of underwatering include wilting leaves, while overwatering can cause yellowing leaves and a soggy soil.
Living Stone
Water very sparingly, only when the leaves become visibly wrinkled and soft. Overwatering is the most common cause of death. During dormancy (winter), watering should be almost completely stopped. Signs of overwatering include mushy leaves and splitting. Signs of underwatering include excessive wrinkling and shriveling.

💡 Pro Tips For Comparing These Plants
Hummingbird Mint Care Tips
Hummingbird Mint is primarily an outdoor plant and requires full sun to thrive. Growing it indoors is challenging due to its high light requirements and potential for pest infestations. It needs well-draining soil and careful watering to prevent root rot. Indoor growth is often stunted and flowering is unlikely.
- Plant in well-draining soil to prevent root rot.
- Provide full sun for optimal flowering.
- Deadhead spent flowers regularly to encourage more blooms.
- Water deeply but infrequently, allowing the soil to dry out between waterings.
- Protect from strong winds, especially taller varieties.
Living Stone Care Tips
Lithops are challenging to grow indoors due to their high light requirements and sensitivity to overwatering. They need very well-draining soil, infrequent watering, and a period of dormancy in winter. Success depends on mimicking their native arid environment.
- Use a terracotta pot to promote drainage.
- Water only when the leaves are visibly wrinkled.
- Provide excellent ventilation to prevent rot.
- Avoid fertilizing during dormancy.
- Repot in fresh soil every 2-3 years.

❓ Frequently Asked Questions — Comparing These Plants
Hummingbird Mint
What are the light requirements for Hummingbird Mint?
Hummingbird Mint requires at least six hours of direct sunlight per day to thrive. Choose a location in your garden or on your patio that receives full sun exposure. If growing indoors, place the plant near a sunny window, preferably one facing south or west. Insufficient light can result in weak growth, fewer blooms, and leggy stems. If your plant is not getting enough natural light, consider supplementing with a grow light. Rotate the plant regularly to ensure even light exposure on all sides.
How do I care for Hummingbird Mint?
Hummingbird Mint thrives in full sun and well-draining soil. Water deeply but infrequently, allowing the soil to dry out between waterings. Avoid overwatering, which can lead to root rot. Fertilize lightly in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers regularly to encourage continuous blooming throughout the summer and fall. Prune back the plant in late winter or early spring to remove dead or damaged growth and maintain its shape. Provide good air circulation to prevent fungal diseases. In colder climates, provide winter protection by mulching around the base of the plant.
How do I propagate Hummingbird Mint?
Hummingbird Mint can be propagated through division, stem cuttings, or seed. For division, carefully dig up the plant in spring or fall and divide the root ball into smaller sections, each with healthy roots and shoots. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist until they root. Seeds can be sown indoors in early spring or directly outdoors after the last frost.
Living Stone
What are the light requirements for Living Stone?
Living Stones thrive in bright, direct sunlight. They need at least 4-6 hours of direct sunlight daily to maintain their compact shape and vibrant colors. An east or south-facing window is ideal. If you don’t have enough natural light, supplement with a grow light. Insufficient light can cause them to stretch and lose their color, a condition known as etiolation. Rotate your plant regularly to ensure even light exposure. Monitor your plant closely and adjust its position as needed to provide optimal light.
How do I care for Living Stone?
Living Stones require very specific care to thrive. Plant them in a well-draining succulent mix with added grit or perlite. Provide them with bright, direct sunlight for at least 4-6 hours daily. Water sparingly, only when the soil is completely dry, typically only a few times a year. Avoid watering during their dormancy period (usually late fall to early spring) when they are splitting. Overwatering is the most common cause of death. Maintain a temperature between 65-80°F (18-27°C). Repot only when necessary, and choose a pot with drainage holes. Fertilize very lightly, if at all, during the growing season (spring and summer).
How do I propagate Living Stone?
Living Stones are typically propagated by seeds or offsets. Offsets are small plants that grow alongside the parent plant. To propagate from offsets, gently separate them from the parent plant when they are large enough to handle. Plant the offsets in well-draining succulent mix. Water sparingly until they establish roots. Seed propagation is more challenging but can be done by sowing seeds on the surface of moist succulent mix. Cover with a clear lid or plastic wrap to maintain humidity. Keep in a warm, bright location until germination occurs. Gradually acclimate the seedlings to drier conditions. Leaf cuttings and stem cuttings are not viable methods for Lithops.
