OSIANA ROSE|HYBRID TEA ROSE

OSIANA ROSE

• Osiana is a hybrid tea rose cultivar bred by Rosen Tantau in Germany in 1989. 

• It is sometimes listed under the synonym “Oceana”. 

• It belongs to the “grandiflora” / large-flower type of roses: large blooms, long stems, good for cutting. 

Appearance & Characteristics

• Flower colour: Ivory to creamy white, sometimes with peach or apricot blush tones. 

• Bloom size: Approximately 8-10 cm diameter in typical listings; some sources claim up to 10-12 cm. 

• Plant height: Typically about 1 m to 1.5 m (100-150 cm) for garden shrubs. 

• Growth habit: Bush/arbustive habit (a shrub rose rather than climbing).

• Fragrance: It has a fruity scent (some sources mention hints of vanilla, peach, or bergamot). 

• Usage: Suitable for garden planting, grouping, sometimes in containers; also good as a cut flower due to long stems and bloom quality. 

Growing & Care Notes

• Light: Prefers full sun (important for good bloom and form) rather than heavy shade. 

• Soil / moisture: Needs well-drained fertile soil; watering regular but ensure soil not left to dry out fully during growth.

• Temperature / climate: It is rated in one source as H6 (meaning hardy down to about –20 to –15 °C) in European hardiness ratings. 

• Care: Regular feeding (fertiliser for roses) and protective measures against pests & diseases suggested, since while attractive, it is described as “sensitive” in some write-ups. 

• Vase life / post-harvest: Interestingly, though good for cutting, research shows Osiana is highly sensitive to ethylene (a plant hormone/gas that accelerates senescence) which can drastically reduce its vase life if exposed. 

Pros & Cons Summary

Pros:

• Elegant, large blooms in attractive ivory/peach tones.

• Good for garden decorative use and potentially as cut flower.

• Established cultivar with good pedigree.

Cons:

• Sensitive to ethylene → reduced vase life if cut and transported or kept in less than optimal conditions.

• May need attentive care (soil, feeding, sun) to bring out best blooms.

• In some climates/florists’ environments might require more protection/control than very hardy/mass market roses.
