Sirius Bedding Rose

Rosa x hybrida 'Sirius'

The Story

Plant Bio

The genus Rosa comprises deciduous and evergreen woody shrubs famed for their fragrant, multi-petaled blossoms and thorny stems. Native primarily to the temperate regions of the Northern Hemisphere, these plants have been hybridized for centuries to optimize bloom frequency, disease resistance, and growth habit.

'Sirius' is a compact, upright bedding rose distinguished by its continuous repeat-blooming cycle from late spring through fall. Its semi-double to double flowers open in a warm peach-apricot shade before fading to a clean, radiant white against glossy green foliage.

Uses & Benefits:

Produces continuous flushes of semi-double flowers that transition from warm apricot to pure white, set against glossy green foliage.

Features self-cleaning petals that drop cleanly from the plant, reducing the need for manual deadheading.

Provides pollen for bees and other beneficial insect pollinators throughout the extended blooming season.

Planting

How to Grow

Select a planting site that receives at least six hours of direct sunlight daily and features fertile, well-draining soil.
Dig a hole twice as wide as the root ball, positioning the plant so the graft union sits just at or slightly below the soil surface.
Backfill the hole with native soil amended with organic matter, firm gently, and water deeply to settle the roots.
Apply a three-inch layer of organic mulch around the base to conserve moisture, keeping it clear of the main stems.

Pro Tip

Position the graft union just below the soil surface in cold climates to protect it from freeze damage, and do not mistake the natural color shift from apricot to white for a disease or incorrect cultivar.

Care Guide

Do

Water deeply at the base of the plant to keep foliage dry and minimize fungal infections.
Prune the canes back hard to three to five buds in early spring to stimulate vigorous new flowering wood.
Apply a balanced slow-release rose fertilizer twice a year, once in early spring and again in mid-summer.

Don't

Do not allow the soil to become waterlogged or boggy, as wet conditions promote root rot.
Do not prune back into old, leafless deadwood that lacks visible, active buds.
Do not overhead water during the evening, which leaves foliage damp and increases disease susceptibility.
