Eulalia (Miscanthus sinensis 'Rigoletto')
Miscanthus sinensis 'Rigoletto', or Eulalia, is a compact ornamental grass featuring green leaves striped with white, offering year-round texture.
Complete Plant Information
Overview
Miscanthus sinensis ‘Rigoletto’, commonly known as Eulalia, is a highly valued cultivar prized for its striking, densely variegated foliage. This compact, clump-forming ornamental grass brings strong vertical interest to the garden with narrow green leaves streaked vividly with white stripes. It maintains good stature, growing shorter and more upright than some similar variegated types, reducing late-season flopping.
This Eulalia is a reliable warm-season performer, offering texture and structure throughout the growing season, culminating in attractive bronze flowers beginning in late summer. It transitions beautifully into winter, providing architectural presence, especially when dusted with frost or snow. Miscanthus sinensis ‘Rigoletto’ offers low maintenance once established, making it an excellent choice for long-term structural planting.

How to Grow
Plant Miscanthus sinensis ‘Rigoletto’ in the spring or early fall, ensuring it receives average, medium-moisture, well-drained soil. While it performs best in full sun, this Eulalia tolerates part shade, though reduced light can lead to less vigorous growth and increased flopping late in the season. This cultivar is remarkably adaptable and tolerates a wide soil range, from sandy substrates to the heavy clays common in many regions.
Water moderately, especially when establishing; the plant prefers moist conditions but is quite drought-tolerant once fully rooted. Fertilizing is rarely necessary, as excessive nutrients can encourage weak, floppy growth patterns. Since clumps expand slowly via short rhizomes while remaining tightly tufted, division is only occasionally required, typically done in late winter or early spring before new shoots emerge.
A key element of care involves winter preparation. Keep the foliage standing throughout winter to protect the crown and provide desirable winter structure. Wait until late winter, just before new growth begins, to cut the entire clump back close to the ground. Be mindful that in milder sections of its range, Miscanthus sinensis ‘Rigoletto’ may reseed, so mulch application can help inhibit unwanted spread.
Landscape Uses
Miscanthus sinensis ‘Rigoletto’ excels as a versatile structural element in diverse landscape designs. Its variegated foliage and defined upright habit make it an ideal accent plant to break up masses of solid green perennials or shrubs. Use it as a specimen to draw the eye, or group several together for a dramatic border effect along walkways or property lines.
The sturdy texture of this Eulalia also integrates well into wild gardens, meadows, or cottage garden settings, providing contrast against softer-textured companions. Because the dried flowers and plumes retain their form well into winter, they are excellent for adding lasting interest to naturalized areas or near pond peripheries. The long-lasting nature of the plumes also makes them a superb choice for use as dried material indoors.

Noteworthy Characteristics
The ‘Rigoletto’ cultivar forms a distinct, densely-tufted foliage clump featuring narrow, arching green leaves boldly variegated with white stripes. Unlike some other variegated forms, this Miscanthus sinensis adapts to grow shorter and more erect, resisting the tendency to flop in the late season. Tiny bronze flowers appear in tassel-like inflorescences in late summer, maturing into silvery white plumes that provide ornamental appeal lasting well into winter.

Potential Problems
This stalwart ornamental grass generally avoids frequent insect or disease issues. However, gardeners should monitor for potential problems such as miscanthus mealybug, which develops inside the stems causing severely stunted growth and proves difficult to eradicate. Additionally, miscanthus blight, a fungal disease, attacks the blades and sheaths, and leaf rust can occasionally manifest. To manage potential invasive reseeding, especially in warmer climates, ensure adequate mulching around the base of your Miscanthus sinensis ‘Rigoletto’.

Conclusion
Miscanthus sinensis ‘Rigoletto’ proves invaluable garden asset due to its reliability, low maintenance needs, and dramatic white-striped foliage that lights up the landscape all season long. Integrating this handsome Eulalia into your design ensures textural contrast and winter structure. Before planting, confirm that your site falls within USDA Zones 5-9 to guarantee the best performance from your new specimen.
Companion Planting
Selecting appropriate neighbors helps showcase the unique vertical texture and variegation of Miscanthus sinensis ‘Rigoletto’. Pair this Eulalia with broad-leafed, mounding perennials that contrast its fine texture. Consider planting near plants that bloom later than the Miscanthus, such as late-blooming coneflowers (Echinacea) or sedums, to maintain interest into the fall and winter. Because this grass prefers medium moisture, companion plants should share similar water requirements to simplify irrigation management.
Design Ideas: Winter Structure
One of the significant benefits of planting Miscanthus sinensis ‘Rigoletto’ is its architecture after the growing season ends. Unlike deciduous plants that disappear entirely, the dried foliage and spent plumes of this ornamental grass maintain a strong vertical, often feathery, form throughout winter. Place the clump where it can be viewed from a window or near an entrance path. The neutral beige-tan tones are beautiful when backlit during low winter sun or highlighted by snow, preventing the garden from looking sparse during colder months.
