What colour is Rose Osiria?

The bicolour effect is the main attraction of Rose Osiria.

Its flowers can display:

• deep red
• crimson
• burgundy-red
• cream-white
• silvery-white petal reverses

As the flowers open, the pale reverse of the petals becomes more visible, creating the distinctive red-and-white contrast associated with this variety.

The balance of red and pale colouring may vary naturally with temperature, sunlight and flower age.

This makes Osiria especially appealing to gardeners searching for a red and white rose, two-tone rose or bicolour Hybrid Tea rose.

Fragrance

Rose Osiria has a strong fragrance.

Its perfume, combined with the dramatic flower colour, makes it particularly suitable for planting near:

• patios
• seating areas
• entrances
• pathways
• cutting gardens

where both the flowers and scent can be enjoyed at close range.

Where to plant Rose Osiria

Choose a sunny position with fertile, well-drained soil.

Its red-and-white flowers combine particularly well with:

• white roses
• cream flowers
• dark red roses
• pale pink flowers
• purple and lavender plants
• silver foliage

Because Osiria has such a strong bicolour pattern, it works particularly well as a feature rose or alongside simpler single-colour varieties.

Allow approximately 60–80 cm between plants for mature growth and good air circulation.

Planting your bare-root Osiria rose

Unpack your rose promptly after delivery and keep the roots moist until planting.

Soak the bare roots in water for several hours before planting to help rehydrate them.

Choose a sunny position with fertile, well-drained soil.

Dig a planting hole wide enough for the roots to spread naturally without bending or crowding.

Backfill with soil, firm gently around the plant and water thoroughly.

Bare-root roses are best planted during the dormant season when the soil is neither frozen nor waterlogged.

Explore Bare Root Roses

Rose Osiria is supplied as part of our Bare Root Roses collection during the dormant planting season.

Autumn and winter are excellent times to establish bare-root roses, allowing the roots to settle before strong spring growth begins.

Caring for Rose Osiria

Water regularly during dry periods, especially during the first growing season.

Apply a suitable rose fertiliser during active growth according to the manufacturer's instructions.

Remove faded flowers regularly to encourage repeat blooming.

Prune in late winter or early spring by removing:

• dead stems
• damaged growth
• weak shoots
• crossing branches

Then shorten healthy stems to encourage strong new flowering growth.

Good sunlight and air circulation will help maintain healthy foliage.
