Introduction

Flower Carpet® YELLOW is a buttercup-yellow groundcover rose, one of the series of Flower Carpet groundcover roses introduced by Anthony Tesselaar International. Bred by Noack Rosen, the German rose hybridizers known for their early commitment to disease-resistant hybrids, Flower Carpet YELLOW shares the impressive natural disease-resistance of its Flower Carpet cousins.

Flower Carpet YELLOW is a top-performing groundcover rose that blooms profusely from late spring through fall and, like its predecessors, exhibits excellent natural disease-resistance in the landscape. It is worth noting that Flower Carpet YELLOW is the most upright and shrubby variety of the Flower Carpet series.

Flower Carpet YELLOW has yellow semi-double flowers with darker yellow stamens. Its color doesn’t fade quickly in the sun, the rich yellow blossoms stay vibrant for a day or more then slowly soften in hue over time while still retaining a vivid yellow presence in the landscape. The flowers are arrayed in clusters of 5 to 6 blossoms each, on average. Its glossy green foliage continues to look fresh all season.

Suggested Uses

Flower beds, mass plantings, large containers, landscapes, hanging baskets, and as tree roses. A perfect commercial landscaping plant for low-maintenance color.

Growth Habit

Bushes are vigorous and compact, more upright than the other Flower Carpet ground cover roses.

Growth Pattern

To invigorate blooming once plants are established, cut canes back to 10 inches annually in late winter or early spring.

Plant Size

36 inches in height, 30 inches across (spread) depending upon pruning. Pruning to induce branching makes bush more compact.

Flower Size

2- to 2½ - inches in diameter.

Spacing

Plant 3 per square yard, for ground cover. Plant 2 feet apart to establish boundaries.

Hardiness

Will thrive in USDA zones 5 through 10. In colder zones, protect over the first winter. In zones 5 and below, continued winter protection is advised. Handles warm climates well. In areas of intense dry heat protect by planting in semi-shade (with plenty of filtered light), keeping well-watered.

Flowering Period

Produces masses of blooms late Spring to Fall. Flowers typically last 3 to 4 days.

Flower Color

Buttercup-yellow semi-double flowers with yellow stamens, 15 to 20 petals each. Color doesn’t fade quickly in the sun as many yellow roses do.

Fragrance

Not fragrant.

Foliage

Rich glossy green, medium sized leaves.

Pruning/Pinching

No fancy pruning needed. Cut back by ⅔ annually in late winter or early spring. Trim to shape anytime of year, if desired. The bush is self-cleaning with few rose hips, no dead-heading required, petals fall away cleanly.

Light Needs

For best bloom, grow in full sun. Grows well in partial shade (4 to 5 hours of sun per day) with reduced blooms. In areas of intense dry heat and sun, plant in semi-shade/filtered light.

Soil Needs

Can thrive in a variety of soil conditions. Performs best in well-drained friable garden soil with added organic matter.

Water Needs

When planting in the landscape, water in well particularly during hot conditions and continue to water regularly until the plant is established. Flower Carpet roses are very tolerant of dry conditions once established.

Fertilizer

For maximum flowering and performance, feed with a balanced rose food. It is best not to feed roses in fall and winter as forcing new growth that late in the season can increase the chances of cold-damage over winter. In warm climates (USDA zones 8 and up): feed in early spring and late summer. In cold climates (USDA zones 5 through 7): feed in spring only.

Disease Tolerance

Very resistant to common rose blights such as black spot and mildew. It does not require routine chemical spraying and dusting, apply only if needed.

Pest Issues

Treat for insect pests only as needed.

Special Care

In zones 5 and below, winter protection is advised, especially in first winter.
