How to Grow

Planting Hemerocallis ‘Sidewinder Oh Seven’ is best done in spring or fall, ensuring the fibrous roots establish before extreme weather hits. These Daylilies perform well in a wide range of soils, but the ideal location features deep, fertile loams with medium moisture and excellent drainage. Place plants where they receive full sun for the best bloom count, though they tolerate part shade.

Maintenance for this low-maintenance variety is straightforward. Deadhead spent flowers daily, a practice that encourages repeat blooming, and remove the entire flower scapes once blooming has finished completely. While Daylilies tolerate heat and humidity, deep watering during dry spells is appreciated to keep the foliage looking lush and attractive throughout the summer.

For optimal performance, mature clumps of Daylily should be divided every three to four years, ideally in the spring, especially in colder winter regions like the St. Louis area. Be aware that Hemerocallis ‘Sidewinder Oh Seven’ is a winter dormant type; it requires a cold period for best blooming and is therefore less suitable for the warmest extent of its range (Zone 9 and above).

Landscape Uses

The reliable structure and vibrant blooms of Daylilies make them essential workhorses in landscape design. Hemerocallis ‘Sidewinder Oh Seven’ excels when used in mixed perennial borders, providing vertical accents softened by its slender, arching foliage. They are superb for edging pathways or mass planting over large slopes where their low maintenance requirements are highly valued.

Planting Daylilies in drifts creates a powerful visual impact, particularly when paired with contrasting textures like hostas or spiky ornamental grasses. While this cultivar matures to about two feet, smaller varieties are often utilized in rock gardens, though ‘Sidewinder Oh Seven’ is perfectly sized for mid-border placements where its unique pink blooms can be easily viewed.
