Princess Feather, scientifically known as Persicaria orientalis, offers unique visual appeal and vertical interest to many garden spaces. Its distinctive form, prolific blooms, and ease of cultivation make it a popular choice for both new and experienced gardeners.
Understanding Princess Feather
Persicaria orientalis is an annual plant, completing its life cycle within a single growing season. It typically grows quite tall, reaching heights between 4 to 9 feet, though some varieties may be shorter. The plant features broad, ovate to heart-shaped, mid-green leaves that contribute to its full appearance.
Its defining characteristic is showy, pendulous flower plumes, ranging from pink to red, sometimes white. These dense, tassel-like spikes dangle gracefully from arching stems, earning common names like ‘Kiss-Me-Over-the-Garden-Gate’ and ‘Prince’s Plume’. Native to Eastern Asia and Australasia, this fast-growing plant blooms continuously from mid-summer until the first frost.
How to Grow Princess Feather
Light Requirements
Princess Feather thrives in locations that receive full sun, which promotes the most abundant flowering. While it prefers ample sunlight, it can also tolerate partial shade, particularly in hotter climates where intense afternoon sun might be too strong. Plants grown in shadier conditions may grow taller but might produce fewer flowers or bloom later in the season.
Soil Preferences
Princess Feather thrives in well-draining, moist soil rich in organic matter, with a pH from slightly acidic to neutral. While it prefers fertile conditions, Persicaria orientalis tolerates a range of soil types, including those with modest fertility. Good drainage is important to prevent waterlogging, which can harm roots.
Watering Needs
Consistent moisture benefits Princess Feather, especially during dry periods. Keep the soil moist but not waterlogged, as excessive wetness can cause issues. Established plants tolerate some drought, but regular watering promotes vigorous growth and flowering.
Planting Seeds and Spacing
Sow Princess Feather seeds directly outdoors after the last frost or start indoors for earlier blooms. For optimal germination, cold stratify seeds by refrigerating them for three to four weeks. Sow thinly, lightly cover with compost, and maintain 18-22°C (64-71°F) for germination, which takes two to eight weeks. Once seedlings are large enough, space them 30-60 cm (12-24 inches) apart for air circulation and mature growth.
Ongoing Maintenance
After establishment, Princess Feather care is straightforward. Deadheading spent flower spikes encourages more blooms and prevents excessive self-seeding. Taller varieties may need staking to prevent flopping, especially in wind. While the plant prefers modest fertility, a balanced liquid fertilizer (e.g., 10-10-10 N-P-K) can be applied every 4-6 weeks if growth is slow or flowering inhibited. Avoid over-fertilizing, particularly with high nitrogen, as this can cause lush foliage at the expense of flowers or leggy growth.
Uses and Garden Impact
Princess Feather integrates well into various garden designs. Its towering stature and graceful, arching flower plumes make it an an excellent choice for the back of borders, cottage gardens, or as a striking focal point. It also performs well in large containers, adding a vertical element to patio or balcony displays.
Beyond its aesthetic contribution, Persicaria orientalis attracts a variety of beneficial insects to the garden. Its nectar-rich flowers are particularly appealing to pollinators like bees, butterflies, and hummingbirds. The long-lasting blooms also lend themselves well to floral arrangements, serving as a unique and elegant cut flower for indoor displays.
Troubleshooting Common Issues
Princess Feather is a robust plant, generally experiencing few pest or disease problems. Slugs may occasionally be observed, but issues are typically not severe.
Leggy or sprawling stems can occur from insufficient light or overly rich soil. Adequate sunlight and avoiding excessive fertilization help maintain an upright form. Pinching back leggy stems encourages bushier growth, though extensive pre-flowering pruning may reduce blooms. A lack of flowering may indicate insufficient light or nutrient imbalance; ensure full sun and appropriate feeding for better bloom production. Protecting tall plants from strong winds also prevents damage and flopping.
