Special Attributes

Breeding a good white daylily has long been the Holy Grail among daylily breeders and Joan Senior is simply one of the best white daylilies to ever be created. Large flowers, 5-6" across, emerge creamy to pale yellowish white and become almost pure white as the day progresses. The ruffled petals are slightly recurved and the flowers have a soft lime-green eyezone. A long flowering period for two months during summer.




Landscape & Garden Uses

Growing to in a 25 inches tall and gradually spreading to form an 18 to 24 inch wide clump, the Joan Senior Daylily is ideal for use in groupings, stunning mass plantings or as a border along paths and walkways in landscape borders or mass planted on embankments, hillsides and slopes. Also nice as an accent or small grouping in small garden spaces or as a solo or mixed with other sun-loving plants in combination container gardens. A fine addition to daylily gardens, perennial gardens or white color theme gardens. 

Spacing:  15-18 inches for mass plantings or as a solid border edger; 36 inches or more for space between plants





Cultural Preferences

When planted right and in the right spot, Daylilies are exceptionally easy to grow. Though they will perform well in a wide range of soil types and conditions, they prefer a moist but well-drained soil of average fertility. Full to mostly sun is preferred however plants will tolerate some lightly filtered sun or shade.We suggest at least 5 hours of direct sunlight for best flowering. Daylilies don't require deadheading but the removal of spent flower scapes (stems) encourage rebloom. When established, daylilies are moderately drought tolerant.
