The Pink Lily of the Valley, Convallaria majalis ‘Rosea’, offers a charming and less common alternative to its widely recognized white counterpart. This delicate plant offers a unique touch to garden spaces as an unusual groundcover. Its subtle coloration and sweet fragrance make it a distinctive specimen for shaded areas.
Understanding Pink Lily of the Valley
Appearance and Uniqueness
Pink Lily of the Valley distinguishes itself with delicate, bell-shaped flowers that display a pale mauve-pink hue. These fragrant blooms typically emerge in late spring, hanging gracefully along slightly arching stems. The flowers are complemented by broad, elliptic green leaves that contribute to its lush, spreading groundcover habit. This unique coloration offers a gentle visual interest in shaded garden spots.
Rarity and Appeal
Compared to the common white Lily of the Valley, the pink variant is relatively rare, making it a sought-after specimen for plant enthusiasts and collectors. Its scarcity enhances its appeal, drawing gardeners who desire to cultivate something distinctive. The plant’s ability to naturalize and form extensive colonies, combined with its low-maintenance nature, further adds to its desirability.
Scientific Name
The botanical name for Pink Lily of the Valley is Convallaria majalis ‘Rosea’. This classification places it within the genus Convallaria, which contains a single species, C. majalis, commonly known as Lily of the Valley. The ‘Rosea’ designation indicates it is a specific cultivar selected for its pink flower color. It belongs to the Asparagaceae family.
Cultivating Pink Lily of the Valley
Site Selection and Soil
Pink Lily of the Valley thrives in shaded or partially shaded locations, making it an excellent choice for woodland gardens or beneath trees. It prefers fertile, organically rich, and well-drained soil that maintains consistent moisture. An ideal soil pH ranges from slightly acidic to neutral, typically between 5.0 and 7.0. While it can tolerate a range of soil conditions, including clay, amending the soil with compost or well-rotted manure improves drainage and nutrient content, promoting healthier growth.
Planting Pips
Pink Lily of the Valley is typically planted using rhizomes, often referred to as “pips.” The optimal time for planting is in early spring or fall. Dig a hole large enough to accommodate the rhizome, ensuring the pointed growth buds face upwards. Spread the roots out, and cover them with soil so the growth bud is about 1/2 inch below the surface. Space individual pips approximately 4 to 6 inches apart.
Light Requirements
This plant flourishes in partial to full shade, performing best when protected from intense midday and afternoon sun. While it can tolerate some morning sun, especially in cooler climates, full shade is preferable in warmer regions to prevent foliage from browning. Adequate shade also helps maintain consistent soil moisture.
Watering Practices
Consistent moisture is important, as Pink Lily of the Valley prefers evenly moist but not waterlogged soil. Regular watering is particularly important during dry periods or when the plant is establishing itself. Watering in the early morning allows the plant to absorb moisture throughout the day and helps prevent fungal issues. While it appreciates humidity, avoid overwatering to prevent root rot.
Temperature and Climate
Pink Lily of the Valley is a hardy perennial, thriving in USDA Hardiness Zones 2 through 8. It tolerates cold winters, requiring a period of cold dormancy for optimal blooming. However, it does not perform well in hot, dry climates, where summer heat can cause the foliage to die back. In such conditions, providing full shade and consistent soil moisture is important.
Fertilizing
Pink Lily of the Valley generally does not require extensive fertilization, especially if planted in soil rich in organic matter. If the soil is poor, a light application of a balanced slow-release granular fertilizer in spring can be beneficial. Alternatively, incorporating compost or well-rotted manure into the soil in early fall can provide necessary nutrients and improve soil structure. Avoid over-fertilizing, as this can encourage leaf growth at the expense of flowers.
Ongoing Care and Propagation
Pest and Disease Management
Pink Lily of the Valley is generally robust and does not suffer from many serious pest or disease issues. Occasionally, slugs and snails may appear, causing ragged holes in the leaves. Fungal diseases like leaf spot or powdery mildew can occur, especially in humid conditions. Ensuring good air circulation by avoiding overcrowding and watering at the base of the plant helps prevent these issues. Promptly removing affected foliage can also help manage disease spread.
Winter Care
As a hardy perennial, Pink Lily of the Valley naturally enters a dormant state in winter and requires minimal care. The above-ground parts of the plant die back, while the underground rhizomes remain alive. In colder regions, a light layer of mulch can be applied around the plants in late fall to provide additional insulation, though it is not always necessary due to the plant’s hardiness.
Propagation Through Division
Propagating Pink Lily of the Valley is effectively done through the division of its rhizomes. This process can be undertaken in late fall or early spring when the plant is dormant. To divide, carefully dig up a clump and gently separate the rhizomes, also known as pips, into smaller sections. Each section should have some roots attached. Replant these divisions at the same depth as the original plant, about 4 to 6 inches apart, and water thoroughly. Division also helps rejuvenate older, dense patches and encourages more vigorous blooming.
Safety and Sourcing
Safety
All parts of the Lily of the Valley plant, including the pink varieties, are toxic if ingested due to cardiac glycosides. Exercise caution, especially in gardens frequented by children or pets. Wearing gloves when handling the plant is also recommended.
Sourcing
Due to its relative rarity, Pink Lily of the Valley may not be as readily available at all local garden centers. Interested gardeners can typically find pips or plants from specialty nurseries, online retailers, or mail-order catalogs. When sourcing, look for reputable suppliers to ensure healthy and true-to-type plants.
