Daylily (Hemerocallis ‘Autumn Red’)

Hemerocallis 'Autumn Red' is commonly called the Autumn Red daylily. It is an herbaceous perennial known for dark red flowers with gold throats and midribs.

Hemerocallis 'Autumn Red' grows best in full sun to partial shade. Provide at least 6 hours of direct sun for the strongest flowering, although it can tolerate some afternoon shade.

Water Hemerocallis 'Autumn Red' moderately, keeping the soil evenly moist while it establishes. Once mature, it tolerates short dry periods but benefits from deep watering during prolonged summer drought.

Hemerocallis 'Autumn Red' is generally suitable for USDA Zones 3 through 9. Local performance can vary with winter exposure, drainage, and whether the plant is grown in the ground or in a container.

Hemerocallis 'Autumn Red' typically forms a clump about 2.5 to 3 feet tall and 1.5 to 2.5 feet wide. Its flower scapes can rise to roughly 39 inches.

Hemerocallis 'Autumn Red' prefers fertile, well-drained loam but also grows in sandy or clay soil. Improve very heavy or compacted ground with organic matter and avoid locations that stay waterlogged.

Hemerocallis 'Autumn Red' can grow in clay soil if drainage is adequate. Incorporate compost and plant slightly high if necessary, because consistently saturated roots can reduce vigor and increase disease problems.

Hemerocallis 'Autumn Red' can grow in partial shade, but flowering is usually stronger in full sun. Too much shade may produce attractive foliage while reducing the number and quality of flowers.

Hemerocallis 'Autumn Red' has some drought tolerance after establishment. Extended dryness can reduce flower size and bud production, so water deeply during prolonged hot or dry weather.

Hemerocallis 'Autumn Red' is generally easy to grow and requires low maintenance. Good drainage, adequate sunlight, and occasional deep watering during drought are usually sufficient for reliable performance.

Insufficient sunlight is a common reason Hemerocallis 'Autumn Red' fails to bloom. Other possibilities include drought stress, excessive nitrogen, overcrowding, or a recently divided plant that is still reestablishing.

Deadhead Hemerocallis 'Autumn Red' by removing spent flowers for a tidier appearance. Deadheading is optional for plant health, but it can prevent seed formation and direct more energy toward the clump.

Cut the flower scapes of Hemerocallis 'Autumn Red' back after blooming finishes. Remove yellow or dead foliage as needed, while leaving healthy leaves in place until they naturally decline.

Hemerocallis 'Autumn Red' may occasionally be affected by aphids, thrips, mites, slugs, or snails. Inspect new growth and flower buds regularly, and remove heavily damaged plant material.

Hemerocallis 'Autumn Red' can be affected by leaf spot, rust, or rot, especially in crowded or poorly drained conditions. Improve air circulation, water at the soil surface, and remove diseased foliage.

Plant Hemerocallis 'Autumn Red' in spring or early fall. Spring planting is preferable in regions with severe winters, while early fall planting gives roots time to establish before freezing weather.

Space Hemerocallis 'Autumn Red' about 18 to 24 inches apart. This allows the clumps to expand while preserving airflow and reducing overcrowding as the plants mature.

Plant Hemerocallis 'Autumn Red' with the crown about 1 inch below the soil surface. Spread the roots outward, backfill firmly, and water thoroughly after planting.

Hemerocallis 'Autumn Red' can be grown in a large, wide container with drainage holes. Choose a pot that allows room for the clump and protect the root ball from extreme winter freezing.

Divide Hemerocallis 'Autumn Red' by lifting the clump and separating it into smaller sections, each with roots and several fans. Replant the divisions promptly in well-drained soil and water them thoroughly.

Divide Hemerocallis 'Autumn Red' in early spring or early fall. Spring is generally safer in colder climates, while fall division should be completed early enough for roots to establish before the ground freezes.

Divide Hemerocallis 'Autumn Red' about every 3 to 4 years when the clump becomes crowded or flowering declines. Healthy plants can remain undivided longer if they continue blooming well.

Hemerocallis 'Autumn Red' can produce seeds, but seedlings will not reliably reproduce the named cultivar. Divide the clump instead when you want new plants that match the parent.

Yes, Hemerocallis 'Autumn Red' is toxic to cats. All parts should be kept away from cats because ingestion can cause serious poisoning, and suspected exposure requires immediate veterinary advice.

Hemerocallis 'Autumn Red' usually blooms in midseason, commonly from June through August in much of the United States. Exact timing varies with climate, weather, and growing conditions.

Hemerocallis 'Autumn Red' produces dark red to velvety red flowers with gold throats and lighter midribs. The flowers are typically single and about 5 inches across.

Hemerocallis 'Autumn Red' may rebloom lightly after its main midseason display. Reblooming is influenced by sunlight, moisture, plant maturity, and regional growing conditions, so it is not equally strong every year.

Each flower of Hemerocallis 'Autumn Red' usually lasts for one day, occasionally two. Because many buds open in succession, the entire clump can remain attractive for an extended flowering period.

Hemerocallis 'Autumn Red' can attract butterflies and other flower-visiting insects. Its succession of showy red blooms makes it useful in perennial borders and pollinator-friendly garden plantings.
