Penny Mac (Hydrangea macrophylla ‘Penny Mac’)

Grow Hydrangea macrophylla 'Penny Mac' in morning sun and afternoon shade, rich moisture-retentive soil, and keep it evenly moist. Protect it from intense afternoon heat, drying winds, and prolonged drought.

Hydrangea macrophylla 'Penny Mac' performs best with morning sun and afternoon shade. It can tolerate more sun in consistently moist soil, but hot afternoon exposure may cause wilting, leaf scorch, or faded flowers.

Water Hydrangea macrophylla 'Penny Mac' deeply whenever the soil surface begins to dry, especially during hot or dry weather. The soil should remain evenly moist but never constantly waterlogged.

Plant Hydrangea macrophylla 'Penny Mac' in rich, humus-rich, moisture-retentive, well-drained soil. Incorporating compost or other organic matter can improve moisture retention without creating stagnant, soggy conditions.

Hydrangea macrophylla 'Penny Mac' is generally suitable for USDA Zones 5 through 9, with protection in colder locations. Severe cold, late freezes, and exposed sites can still damage flower buds and stems.

Hydrangea macrophylla 'Penny Mac' can grow in full sun only where the soil stays consistently moist and summers are not excessively hot. In most U.S. gardens, morning sun with afternoon shade is a safer placement.

Choose a site with morning light, afternoon shade, shelter from drying wind, and organically rich soil. A location near a building or under high, open-canopy trees can provide useful protection without dense shade.

Hydrangea macrophylla 'Penny Mac' commonly grows about 4 to 6 feet tall and wide. Allow enough room for its mature spread so it does not need frequent hard pruning.

Wilting is usually caused by heat, dry soil, intense afternoon sun, or root stress. Check the soil several inches below the surface, water deeply if it is dry, and improve afternoon shade if wilting repeatedly occurs.

Brown leaves commonly result from drought, hot sun, wind, or fertilizer injury. Keep the root zone evenly moist, apply mulch without touching the stems, and avoid heavy fertilizer applications during hot or dry weather.

A lack of flowers can result from winter damage, late spring freezes, excessive shade, drought stress, or pruning at an unfavorable time. Because 'Penny Mac' can bloom on old and new growth, healthy new growth may still produce later flowers after earlier buds are lost.

Hydrangea macrophylla 'Penny Mac' usually needs only moderate feeding in spring if the soil is fertile. Use a balanced, slow-release fertilizer according to its label, because excessive nitrogen can encourage foliage at the expense of flowers.

Yes, apply about 2 inches of organic mulch over the root zone to conserve moisture and moderate soil temperature. Keep mulch a few inches away from the stems to reduce the risk of rot.

Apply a thick organic mulch over the root zone and protect the shrub from drying winter winds. In colder or exposed areas, loosely covering the plant after dormancy can help protect buds, although its reblooming habit may allow later flowers if some buds are damaged.

Plant Hydrangea macrophylla 'Penny Mac' in spring after severe freezes have passed or in early fall while the soil remains workable. Water thoroughly after planting and maintain steady moisture during the first growing season.

Yes, Hydrangea macrophylla 'Penny Mac' can grow in a large container with drainage holes and rich, moisture-retentive potting mix. Container plants dry out and freeze faster than in-ground shrubs, so monitor watering and provide winter protection.

Space Hydrangea macrophylla 'Penny Mac' about 4 to 6 feet apart, depending on whether you want individual shrubs or a fuller hedge. Use the expected mature width and local growing conditions to refine the spacing.

Yes, Hydrangea macrophylla 'Penny Mac' can be propagated from softwood stem cuttings. Take healthy, nonflowering shoots in late spring or early summer and root them in a clean, moist, well-drained medium under high humidity.

Take softwood cuttings from Hydrangea macrophylla 'Penny Mac' during the active growing season, commonly from May through July in the United States. Choose flexible new growth that is beginning to firm but is not yet woody.

Yes, layering is a practical way to propagate Hydrangea macrophylla 'Penny Mac'. Bend a low flexible branch to the soil, lightly wound or bury part of it, secure it, and separate it after roots have formed.

Prune Hydrangea macrophylla 'Penny Mac' immediately after flowering if shaping or size reduction is needed, or remove dead and weak wood in late winter. Avoid routine severe pruning because it can reduce the first flush of flowers.

Hydrangea macrophylla 'Penny Mac' is more tolerant of hard pruning than many traditional bigleaf hydrangeas because it can bloom on new growth, but hard pruning is still best avoided unless necessary. Moderate thinning and removal of the oldest stems usually preserve better structure and flowering.

Hydrangea macrophylla 'Penny Mac' should be treated as moderately toxic if eaten by pets or people. Keep leaves and flowers away from children and animals, and contact a veterinarian or poison-control service if ingestion occurs.

Yes, Hydrangea macrophylla 'Penny Mac' is a reblooming or remontant cultivar that can flower on both old and new growth. This allows additional flowers after early flower buds are damaged or after limited pruning.

Hydrangea macrophylla 'Penny Mac' flowers can range from blue and lavender to pink depending mainly on soil acidity and available aluminum. Color may also vary with local soil conditions, weather, and the plant’s genetics.

To encourage bluer flowers, grow Hydrangea macrophylla 'Penny Mac' in acidic soil with available aluminum and use a labeled hydrangea-bluing product if needed. Results are gradual and depend on soil chemistry, drainage, and the product’s directions.

To encourage pinker flowers, maintain less-acidic soil and use garden lime only according to a soil test and product directions. Color changes may take more than one season and will not be equally strong in every plant.

Flower color changes when soil pH and aluminum availability change around the roots. Hydrangea macrophylla 'Penny Mac' may show blue, purple, or pink flowers in different parts of the plant or in different years as soil conditions vary.

Hydrangea macrophylla 'Penny Mac' generally begins blooming in early to midsummer and may continue into late summer or early fall. Exact timing depends on climate, winter conditions, pruning, moisture, and the plant’s establishment.

Yes, Hydrangea macrophylla 'Penny Mac' is suitable for fresh arrangements and dried flowers. Cut stems when flower heads are fully developed, and for drying, allow the heads to begin aging and becoming papery before cutting.
