Hosta ‘Autumn Frost’

Hosta 'Autumn Frost' is a medium-sized, very hardy perennial grown for its frosty blue-green leaves with wide yellow margins that mature to creamy white. It is a sport of 'First Frost' and is commonly sold in the Proven Winners SHADOWLAND® Collection.

Hosta 'Autumn Frost' typically grows about 10–12 inches tall and spreads around 24 inches wide. Some nursery references list a mature spread closer to 18–24 inches, depending on age and growing conditions.

Hosta 'Autumn Frost' is generally hardy in USDA Zones 3–9. In warmer zones, afternoon shade and consistently moist soil help protect the foliage.

Yes, Hosta 'Autumn Frost' is considered an easy-care perennial when grown in shade or part shade with average moisture. Its main recurring problems are slug damage, animal browsing, and drought stress.

Hosta 'Autumn Frost' grows best in part shade to shade, with protection from intense afternoon sun. Gentle morning sun can improve the yellow margin, but excessive direct sun may scorch the leaves.

Yes, Hosta 'Autumn Frost' can grow in full shade, although its growth may be slower and the yellow margins may be less vivid. Bright, indirect light or filtered shade usually produces the best balance of color and foliage quality.

Yes, Hosta 'Autumn Frost' usually tolerates a few hours of mild morning sun, especially when the soil stays evenly moist. Avoid hot late-afternoon exposure, which can bleach or scorch the variegated leaves.

Use moist, fertile, well-drained soil enriched with organic matter. The soil should retain moisture without staying waterlogged around the crown.

Provide average, consistent moisture, especially during the first growing season and during summer heat. Water deeply when the soil surface begins to dry, and do not allow container-grown plants to dry out completely.

Yes, Hosta 'Autumn Frost' can grow beneath trees in filtered shade if it receives adequate water. Avoid planting it directly against large tree roots, which can compete strongly for moisture.

The yellow margins naturally lighten to creamy white as the season progresses, while insufficient light can make the overall foliage appear greener. Excessive shade, drought, or plant stress may also reduce the clarity of the variegation.

Irregular holes in Hosta 'Autumn Frost' leaves are most often caused by slugs or snails, although deer, rabbits, hail, and chewing insects can also be responsible. Check the plant at night and inspect nearby foliage and soil for pests.

Reduce hiding places around the plant, keep mulch from touching the crown, and hand-pick slugs at night or use a locally approved slug-control method. Watering early in the day can also make the planting area less favorable overnight.

No, Hosta 'Autumn Frost' is not reliably deer resistant. Deer may eat the leaves and flower scapes, so fencing or a proven deer-management strategy may be necessary in areas with browsing pressure.

Hosta 'Autumn Frost' usually performs well with fertile soil and does not require heavy feeding. If growth is weak, apply a balanced slow-release fertilizer in spring according to the product label.

Remove the foliage after it has been killed by frost and begins to collapse. Cutting it back too early can reduce the plant’s ability to store energy for the following season.

Plant Hosta 'Autumn Frost' in spring or early fall when temperatures are moderate and the soil is workable. Water it thoroughly after planting and keep the soil consistently moist while roots establish.

Space Hosta 'Autumn Frost' about 24–30 inches apart to allow room for its mature mound. Closer spacing is possible for a faster visual fill, but crowded plants may have reduced airflow.

Yes, Hosta 'Autumn Frost' grows well in a container with drainage holes and a moisture-retentive potting mix. Choose a pot at least 12 inches wide initially and monitor it more often because containers dry out faster than garden soil.

Dig a hole about twice as wide as the root ball, set the crown at the same level it was growing in its container, and backfill with amended soil. Water deeply and apply a light organic mulch without covering the crown.

Yes, Hosta 'Autumn Frost' can be propagated by division. Divide established clumps in early spring as the shoots emerge, using a sharp knife or spade to separate sections with roots and growing points.

Divide Hosta 'Autumn Frost' only when the clump becomes crowded, weak in the center, or larger than its planting space. Healthy hostas can remain undivided for many years.

It can produce seeds, but seedlings may not retain the distinctive variegation of Hosta 'Autumn Frost'. Division or nursery-propagated plants are preferred when an identical plant is needed.

Yes, Hosta 'Autumn Frost' should be considered toxic to dogs if eaten. Ingestion may cause gastrointestinal signs such as vomiting, diarrhea, or depression, so contact a veterinarian if a dog consumes the plant.

Yes, Hosta 'Autumn Frost' should be considered toxic to cats if eaten. Keep cats away from the foliage and contact a veterinarian or animal poison-control service if ingestion occurs.

Hosta 'Autumn Frost' is not generally treated as a major human-poisoning concern, but ornamental hostas should not be eaten unless specifically identified and prepared as an edible hosta species. Keep plant material away from children and consult a medical professional after significant ingestion.

Hosta 'Autumn Frost' generally blooms in summer, often from early to midsummer depending on the climate. The flowers are pale lavender and rise above the foliage on upright scapes.

Hosta 'Autumn Frost' is grown primarily for its foliage, and its pale lavender flowers are not generally considered strongly fragrant. Fragrance is more characteristic of certain other hosta types, such as Hosta plantaginea cultivars.

Remove the flower scapes after blooming if you prefer a tidier appearance or want the plant’s energy directed toward foliage. Leaving them in place does not normally harm an established plant.
