Fern Leaf Lavender vs Lacecap Hydrangea Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Fern Leaf Lavender
Lavandula pinnata
Lavandula pinnata, commonly known as Fern Leaf Lavender, is a perennial shrub characterized by its deeply divided, fern-like leaves, which distinguish it from other lavender species. It typically grows to a height of 1-3 feet. The plant produces fragrant, purple-blue flowers on long stalks, attracting pollinators. While it can be grown in containers, it is primarily an outdoor plant, thriving in sunny, well-drained conditions. People grow it for its unique foliage, aromatic properties, and ornamental value in gardens and landscapes. It is less cold-hardy than English lavender.
Lacecap Hydrangea
Hydrangea macrophylla 'Lacecap'
Lacecap Hydrangeas are deciduous shrubs known for their distinctive flower heads. They feature a central cluster of tiny, fertile flowers surrounded by a ring of larger, showy sterile flowers. This creates a delicate, lace-like appearance. Typically grown outdoors in gardens and landscapes, they offer beautiful blooms in shades of pink, blue, or white, depending on the soil pH. They are not naturally indoor plants and require specific conditions to thrive indoors, making them a challenging choice for indoor cultivation.

❓ Frequently Asked Questions — Comparing These Plants
Fern Leaf Lavender
What are the light requirements for Fern Leaf Lavender?
Fern Leaf Lavender demands ample sunlight to flourish. Aim for at least 6-8 hours of direct sunlight daily. Insufficient light can lead to leggy growth, reduced flowering, and a weakened plant. When growing indoors, place your Fern Leaf Lavender near a south-facing window where it can receive maximum sunlight. If natural light is limited, consider supplementing with a grow light. Rotate the plant regularly to ensure even light exposure on all sides. In hotter climates, some afternoon shade may be beneficial to prevent scorching. Observe the plant’s growth; if it stretches towards the light, it needs more illumination.
How do I care for Fern Leaf Lavender?
Fern Leaf Lavender thrives in full sun and well-draining soil. Water sparingly, allowing the soil to dry out completely between waterings to prevent root rot. Fertilize lightly in the spring with a balanced fertilizer to encourage blooming. Prune after flowering to maintain shape and promote bushier growth. Provide good air circulation to prevent fungal diseases. Protect from frost in colder climates by bringing potted plants indoors or covering them with frost cloth. Deadhead spent flowers to encourage further blooming. Monitor for pests like aphids and spider mites, and treat accordingly. Avoid overwatering, especially during the winter months. Ensure the plant receives at least 6-8 hours of sunlight daily. Repot every 2-3 years into a slightly larger container with fresh, well-draining soil. Provide adequate drainage in containers to avoid waterlogged soil.
How do I propagate Fern Leaf Lavender?
Fern Leaf Lavender can be propagated through stem cuttings, division, and occasionally from seed. For stem cuttings, take a 4-6 inch cutting from a healthy plant in the spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in well-draining potting mix and keep it moist. Roots should develop in a few weeks. Division involves separating a mature plant into smaller sections, each with its own roots, and replanting them. This is best done in the spring or fall. While keiki formation is uncommon in lavender, stem layering can be used to encourage root growth along a stem while still attached to the parent plant.
Lacecap Hydrangea
What are the light requirements for Lacecap Hydrangea?
Lacecap Hydrangeas prefer partial shade to dappled sunlight. They need at least 4 hours of sunlight each day, but too much direct sun can scorch their leaves and fade their blooms. Morning sun is ideal, followed by afternoon shade. Avoid planting them in locations that receive intense, direct sunlight, especially during the hottest part of the day.
How do I care for Lacecap Hydrangea?
Lacecap Hydrangeas thrive in partial shade with morning sun and afternoon shade being ideal. Water deeply when the top inch of soil feels dry, especially during hot weather. Maintain consistent moisture but avoid soggy conditions. Fertilize in early spring with a balanced, slow-release fertilizer formulated for hydrangeas. Amend soil with organic matter for drainage and fertility.
How do I propagate Lacecap Hydrangea?
Lacecap Hydrangeas can be propagated through several methods, including division, stem cuttings, and, less commonly, from keikis (though keikis are not typical for hydrangeas).
