The “Ultimate Red” daylily likely refers to the famous daylily hybrid Hemerocallis ‘John Benz’ (or occasionally a deeply saturated red cultivar like ‘Red Volunteer’). Known for its saturated ruby red petals, lighter watermark, and distinctive white/green throat, this striking tetraploid perennial is highly sought after by collectors. [1, 2, 3, 4]
Key Characteristics
- Flower Form: Broad ruby-red petals featuring teeth, fangs (ranging from white to chartreuse green), and a lime-green throat.
- Plant Type: Tetraploid daylily (44 chromosomes). These tend to be sturdier with larger, bolder blooms.
- Foliage: Semi-evergreen.
- Bloom Time: Early to midseason bloomer, often showing flowers in early July with some ability to rebloom. [1, 2, 3]
Care & Cultivation
- Sunlight: Prefers full sun to partial shade (at least 6 hours of direct sunlight daily for optimal color).
- Soil: Adaptable but thrives in organically rich, well-draining soil with moderate moisture.
- Hardiness: Generally cold-hardy and heat-tolerant across USDA Zones 3 to 9.
- Spacing: Space plants about 18 to 24 inches apart
