Introduction & History

Deep, mysterious, and hauntingly beautiful, 'Ebb Tide' is a floribunda that pushes the boundaries of rose color into territory few breeders have dared to explore. Introduced by Tom Carruth of Weeks Roses in 2006, this variety produces some of the deepest plum-purple blooms in the rose world, with old-fashioned, fully double flowers that look like they belong in a Pre-Raphaelite painting. Also sold as 'Purple Eden,' Ebb Tide combines this extraordinary color with a rich, powerful spice-clove fragrance that is as unusual and intoxicating as the blooms themselves. The color is so dark and saturated that individual blooms seem to absorb light, creating pools of purple shadow in the garden that shift and deepen as the day progresses. For gardeners who crave the unusual, Ebb Tide is an irresistible siren call.

Breeding History

Bred by Tom Carruth and introduced by Weeks Roses in 2006 under the registration name 'WEKsmopur.' Also marketed as 'Purple Eden' in some regions. The parentage involves 'Sweet Chariot' crossed with 'Blue Nile,' combining miniature rose fragrance genetics with hybrid tea purple coloring. Ebb Tide represents Carruth's exploration of the purple color spectrum, building on years of selecting for deeper, more saturated purple pigments. The variety has received high marks from the American Rose Society and has been featured in numerous rose publications as a color breakthrough.

Flower Form & Fragrance

Blooms are 7-9 cm across with 35-45 petals in a fully double, old-fashioned quartered rosette form. The color is extraordinarily deep plum-purple, among the darkest purples available in roses, sometimes appearing nearly black in bud. Flowers appear in clusters of 3-5 blooms. The fragrance is strong and distinctive: a rich, exotic blend of clove, spice, and old-rose damask that is unlike any other modern floribunda. The scent is most powerful in warm, still conditions. Petals have a velvety texture that enhances the depth of color.

Garden Design & Uses

Ebb Tide creates dramatic focal points in the garden with its intensely dark blooms. Plant near white or pale pink roses for maximum contrast. Silver-foliaged plants like artemisia and lamb's ear make superb companions. It pairs beautifully with lilac, pale yellow, and chartreuse flowers for sophisticated color harmonies. Use in containers near seating areas where the fragrance can be enjoyed. The dark color can get lost in shady spots, so position in good light where the purple tones glow.

Growth Habit & Hardiness

Compact and bushy, reaching 60-90 cm tall with a spread of 45-60 cm. The habit is somewhat compact, making it suitable for smaller spaces and containers. Foliage is medium green, semi-glossy, and medium-sized. Thorns are moderate. Growth is moderate rather than vigorous, with the plant producing quality over quantity. New growth may emerge with purplish tints. The compact stature positions it well as a foreground plant or container specimen.

Climate & Hardiness

Hardy in USDA zones 5b through 9. The deep purple color is most saturated in moderate temperatures of 18-25C. Extreme heat above 35C can cause the purple to lighten or develop blue-magenta tones. Cool weather and overcast conditions produce the deepest, most velvety purple. Cold hardiness is reliable with standard winter protection. Rain can damage the fully double blooms, causing balling in very wet weather. Best in Mediterranean and temperate maritime climates.

Seasonal Care Calendar

Planting & Container Growing

Plant in full sun to light afternoon shade in well-drained, fertile soil at pH 6.0-6.5. Space 45-55 cm apart. Some afternoon shade in hot climates helps preserve the deep purple color and prevents heat stress. Amend soil with compost and well-rotted manure. Mulch with 5-8 cm of organic material. Good drainage is essential, as the compact root system is sensitive to waterlogging.

Container Growing

Feasibility rating: Excellent. The compact habit makes Ebb Tide ideal for containers of 40-50 cm diameter. Use quality potting compost with perlite for drainage. Water when the top 3 cm dries, always at the base. Feed fortnightly with liquid rose fertilizer. Container culture allows precise placement near seating areas for fragrance enjoyment and in positions with optimal light for the best purple color. An outstanding patio rose.

Seasonal Care & Pruning

Spring: Prune to 25-35 cm, maintaining a rounded form. Apply balanced fertilizer and fresh mulch. Begin preventive fungicide program. Summer: Deadhead carefully, as the double blooms can hold water. Water at the base only. Feed fortnightly. Provide afternoon shade in hot areas. Autumn: The deepest purple color returns with cooler temperatures. Continue feeding into early autumn. Clean up fallen leaves. Winter: Standard winter protection. Mound soil in zones 5-6.

Common Mistakes to Avoid

1. Planting in full blazing sun in hot climates where the purple color bleaches. 2. Overhead watering that causes the densely petaled blooms to ball and rot. 3. Under-feeding, which reduces bloom size and color intensity. 4. Expecting the vigor and productivity of a standard floribunda; Ebb Tide prioritizes quality over quantity. 5. Not providing afternoon shade in hot areas, which is important for preserving the dark color.

Propagation

Commercially propagated by budding onto rootstock. Softwood cuttings can be attempted with moderate success rates around 40-50%. The deep purple coloring is generally maintained in cutting-grown plants, though the compact vigor may be reduced. Own-root plants establish slowly but eventually perform well. Difficulty rating: Moderate to difficult. The compact growth habit and moderate vigor make it somewhat slower to root and establish than more vigorous varieties.

Diseases & Pests

Moderate disease susceptibility. Black spot can be problematic in humid climates. The deep purple petals show fungal damage and botrytis readily. Powdery mildew may appear in favorable conditions. A preventive spray program is recommended, particularly in humid areas. Aphids target new growth. Thrips can damage buds before they open. Japanese beetles may feed on the darkly colored blooms. Regular monitoring and proactive care maintain plant health and bloom quality.

Cut Flowers & Exhibition

Cut when buds are half to three-quarters open for the deepest color. The dense petal count means buds take longer to open fully. Stems of 20-30 cm are typical from the compact bush. Place in water with preservative. The unique deep purple color and rich clove fragrance create extraordinary arrangements. Vase life is 5-7 days. Pair with white or cream flowers for stunning contrast. Handle gently, as the dark petals show handling damage.

Collector & Exhibition Notes

Ebb Tide is a must-have for collectors of unusual-colored roses, particularly those building purple and blue rose collections. It performs well in fragrance classes and novelty classes at shows. The extraordinary depth of purple is competitive in any exhibition. Select specimens grown in cool conditions for the most saturated color. The variety represents the current frontier of purple rose breeding. Available from specialist nurseries and online retailers.

Comparison with Similar Roses

Compared to 'Angel Face,' Ebb Tide offers a much deeper, more saturated purple and a more old-fashioned bloom form, with comparable fragrance strength. Against 'Burgundy Iceberg,' Ebb Tide is more consistently purple (rather than temperature-variable burgundy) and more fragrant, but smaller and less vigorous. Versus 'Midnight Blue,' Ebb Tide has a more refined bloom form and stronger fragrance, while Midnight Blue offers a more shrub-like habit.

Heritage & Conservation

As a modern, commercially available variety, Ebb Tide is not at conservation risk. It represents the current state of the art in purple rose breeding and is maintained by Weeks Roses. The variety is significant in the ongoing story of breeding roses in the blue-purple color spectrum, a goal that has driven rose hybridizers for centuries.

Cultural Significance

Ebb Tide represents the ongoing quest by rose breeders to create a true blue rose, approaching from the purple end of the spectrum. The deep plum-purple color has made it a favorite of gardeners interested in dark, gothic, or moody garden aesthetics, a growing design trend. The variety has been featured in floral art exhibitions and design magazines exploring the appeal of dark-colored flowers. It bridges traditional rose culture with contemporary design sensibilities.
