How to Grow

Hemerocallis ‘Tetrina’s Daughter’ should be planted in the spring or fall in average, well-drained soil, although they tolerate a wide range of soil types, preferring deep, fertile loams for optimal performance. Positioning is flexible; ensure the location receives full sun for the most prolific blooming, though they adapt well to partial shade, which may slightly reduce flower count.

Regular water is necessary, particularly during dry spells, as deep watering helps maintain attractive foliage through summer heat and humidity. Maintenance is generally low; the primary task involves deadheading spent flowers daily to maintain neatness and removing the entire flower scape once blooming concludes. Avoid fertilizing heavily, as this can encourage too much foliage growth at the expense of flowers.

For long-term health and vigor, plan to divide clumps of this Daylily every three to four years. Spring division is recommended, especially in colder winter zones. Remember that Hemerocallis ‘Tetrina’s Daughter’ is a winter-dormant type, necessitating that cold period for the best subsequent bloom display, precluding its use effectively in Zone 9 and higher.

Landscape Uses

Hemerocallis ‘Tetrina’s Daughter’ is an exceptionally versatile herbaceous perennial ideal for creating dynamic structure within garden designs. Their predictable height and clumping habit make them perfect for defining the middle layer of flower borders or providing clear, clean edging along pathways. A large mass planting of this Daylily creates a bold, almost architectural statement defined by its uniform lemon-yellow blossoms.

Due to their resilience and low water needs once established, they function well in areas needing reliable color without constant attention. Consider pairing the 3-4 foot height of Hemerocallis ‘Tetrina’s Daughter’ with lower-growing perennials like Salvia or Geraniums in the foreground, or contrasting taller ornamental grasses behind them to emphasize their clean, linear foliage. For large sites, they are excellent for massing over extensive areas where a sweeping wash of color is desired.

Noteworthy Characteristics

The genus name Hemerocallis originates from the Greek words for “day” and “beauty,” reflecting that each spectacular flower lasts only 24 hours, though blooms appear continuously through the season. Hemerocallis ‘Tetrina’s Daughter’ specifically displays 4-inch diameter, trumpet-shaped flowers featuring a light lemon-yellow hue atop stems rising 35-38 inches high. Like most commercial Daylilies, this plant is an extensively developed hybrid featuring fibrous roots and linear, arching, grass-like foliage.

Tolerances

• Rabbit
• Erosion
• Air Pollution

Potential Problems

Daylilies are celebrated for their adaptability and general resistance to pests and diseases, making them a straightforward choice for most gardeners. However, watch for occasional outbreaks of mites, aphids, or thrips, which can usually be managed with targeted insecticidal soap sprays or horticultural oil if populations become concerning. In humid climates, Daylily rust might become an issue; prevention includes ensuring good air circulation around the crowns and removing old foliage promptly in autumn. Rabbits typically ignore these plants entirely, offering pest-free enjoyment.

Before planting, confirm your garden falls within USDA Zones 4-9 to ensure this beautiful Daylily provides its best performance next season.

Companion Planting

Selecting appropriate companions enhances the presentation of Hemerocallis ‘Tetrina’s Daughter’ while supporting a diverse garden ecosystem. Because Daylilies prefer well-drained soil and full sun to part shade, pair them with other mid-summer bloomers that share similar cultural needs. Consider planting shorter mounds of Catmint (Nepeta) or Coral Bells (Heuchera) in front to soften the fans of linear foliage at the base of the Daylilies.

Incorporate Spanish or Siberian Irises nearby, as their foliage emerges earlier, filling in the space as the Daylily foliage begins to develop fully. Companions like Russian Sage or Coneflowers (Echinacea) work well toward the back, as they appreciate the same sun exposure and drainage required by this Daylily cultivar.

Propagation Tips

The primary method for increasing your stock of Hemerocallis ‘Tetrina’s Daughter’ is through division, as hybrid cultivars do not reliably produce true offspring from seed. Division should be performed every 3 to 4 years in early spring or early fall, with spring being the preferred time in very cold climates. Gently dig up the entire clump, taking care not to damage the thick, fleshy roots.

Once the clump is unearthed, use a sharp spade or knife to carefully separate it into smaller sections, ensuring each new division has several fans of foliage attached to a healthy root structure. Replant these divisions immediately at the same depth they were previously growing, watering thoroughly to settle the soil and encourage new root establishment of your Daylily plants.
