Hydrangea vs Lungwort Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Hydrangea
Hydrangea macrophylla
Hydrangea macrophylla is a deciduous shrub known for its large, showy flower heads. Naturally an outdoor plant, it typically grows to 3-6 feet tall and wide. The flower color is pH-dependent, ranging from blue in acidic soils to pink in alkaline soils. White varieties exist as well. People grow hydrangeas for their ornamental value, particularly the vibrant and long-lasting blooms that add color to gardens. While sometimes forced to bloom indoors, they struggle to thrive long-term as houseplants due to high light and humidity requirements.
Lungwort
Pulmonaria officinalis
Pulmonaria officinalis, commonly known as Lungwort, is a herbaceous perennial native to Europe. It's characterized by its distinctive spotted leaves, which are typically green with white or silver blotches. The plant forms a low-growing clump and produces clusters of small, bell-shaped flowers that change color from pink to blue as they mature. Lungwort is primarily grown as an ornamental plant in gardens for its attractive foliage and early spring blooms. It is NOT naturally an indoor plant and will struggle without proper conditions.

🔬 Botanical Information — Comparing These Plants
Hydrangea
| Scientific Name | Hydrangea macrophylla |
|---|---|
| Family | Hydrangeaceae |
| Native To | Japan |
| Also Known As | Bigleaf Hydrangea, French Hydrangea, Lacecap Hydrangea, Mophead Hydrangea |
| Leaves | The leaves are large, ovate to elliptic, and coarsely toothed. They are typically dark green and have a slightly leathery texture. Leaf size can range from 4 to 8 inches long. |
| Flowers | Hydrangeas rarely flower indoors unless provided with very specific conditions. Outdoors, they produce large, globe-shaped or flattened flower heads composed of numerous small flowers. The flower color varies depending on the soil pH. |
Lungwort
| Scientific Name | Pulmonaria officinalis |
|---|---|
| Family | Boraginaceae |
| Native To | Europe |
| Also Known As | Lungwort, Common Lungwort, Jerusalem Cowslip, Spotted Dog |
| Leaves | The leaves of Lungwort are ovate to lance-shaped, typically 10-25 cm long, and have a rough texture. They are characteristically green with white or silver spots, which vary in size and distribution depending on the cultivar. The spots are caused by air pockets within the leaf tissue. |
| Flowers | Lungwort flowers in early spring. The flowers are small, bell-shaped, and borne in clusters. They start as pink or reddish-purple buds and gradually change to blue or violet as they mature. This color change is due to changes in pH levels within the petals. |

💧 Watering Needs
Hydrangea
Water deeply when the top inch of soil feels dry to the touch. Hydrangeas are sensitive to both overwatering and underwatering. Overwatering can lead to root rot, indicated by yellowing leaves and a musty smell. Underwatering causes wilting and dry, crispy leaves. Ensure good drainage.
Lungwort
Keep the soil consistently moist, but not waterlogged. Water when the top inch of soil feels dry to the touch. Overwatering can lead to root rot, while underwatering can cause the leaves to wilt and brown.

❓ Frequently Asked Questions — Comparing These Plants
Hydrangea
What are the light requirements for Hydrangea?
Hydrangeas generally prefer partial shade, with morning sun and afternoon shade being ideal. Too much direct sunlight can scorch their leaves and fade the blooms, while too little light can result in fewer flowers. East-facing locations are often perfect, providing gentle morning sun.
How do I care for Hydrangea?
Hydrangeas thrive with consistent care. Plant in well-draining soil enriched with organic matter. Water deeply when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Fertilize in early spring with a balanced fertilizer formulated for flowering plants, and again after the first flush of blooms.
How do I propagate Hydrangea?
Hydrangeas can be propagated through several methods.
Lungwort
What are the light requirements for Lungwort?
Lungwort thrives in partial to full shade. Direct sunlight can scorch the leaves, especially during the hottest part of the day. Ideally, provide morning sun and afternoon shade, or dappled sunlight throughout the day. When planting Lungwort, consider its light requirements in relation to other plants in your garden. Avoid planting it in areas that receive intense, direct sunlight for extended periods. If growing Lungwort indoors, place it near a north-facing window or in a location with filtered light. Insufficient light can result in leggy growth and reduced flowering.
How do I care for Lungwort?
Lungwort prefers partial to full shade and well-drained, humus-rich soil. Water regularly, especially during dry periods, keeping the soil consistently moist but not soggy. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers. Mulch around the plant to retain moisture and suppress weeds. Deadhead spent flowers to encourage further blooming and prevent self-seeding. Divide established plants every few years to maintain vigor and prevent overcrowding. Monitor for pests such as slugs and snails, and take appropriate action if necessary. Provide good air circulation to prevent fungal diseases.
How do I propagate Lungwort?
Lungwort can be propagated by division, stem cuttings, or root cuttings.
