Planting Your Bare Root Rosa Rugosa 'Alba'

When to plant: November through March, whilst the rose is dormant and the ground isn't frozen

Planting tips:

• Soak roots in water for 2-4 hours before planting

• Dig a hole twice the width of the root system

• Plant at the same depth as the soil mark on the stem

• Space 1-1.5 metres apart for hedging

• Backfill with native soil (additional compost optional – grows well in poor soils)

• Water thoroughly after planting

• Apply a mulch around the base

• No staking required – naturally sturdy growth

Care & Maintenance

• Water during prolonged dry spells in the first season (optional thereafter)

• No feeding necessary – thrives in poor soils

• Minimal pruning needed – just remove dead wood in late winter

• Can be trimmed to shape in early spring if desired

• Wear thick gloves when handling – stems have numerous sharp thorns

• No spraying or special treatments required

• Virtually indestructible once established

• May sucker, forming dense thickets (excellent for barriers and hedges)

Seasonal Interest

Late Spring to Autumn (June-October): Large, single white flowers (8-9cm across) with prominent golden stamens and strong, sweet fragrance. Flowers appear continuously throughout the season, often alongside developing hips.

Summer: Deeply veined, bright green, wrinkled leaves create a lush, textured backdrop

Autumn: Enormous, round orange-red hips develop, often alongside late flowers. Foliage turns bright golden-yellow before falling, creating a spectacular autumn display.

Winter: Persistent hips provide colour and interest; dense, thorny stems create structure and an impenetrable barrier

Wildlife Benefits

Rosa rugosa 'Alba' is outstanding for supporting wildlife:

• Large white flowers are particularly attractive to bees, bumblebees, and butterflies

• Continuous flowering provides nectar and pollen for 4-5 months

• Hips are rich in vitamin C and eaten by thrushes, blackbirds, waxwings, and other birds

• Dense, thorny growth provides safe nesting sites and shelter

• Hips persist well into winter when food is scarce

• Supports various moth species

Ideal For

• White gardens and moon gardens

• Coastal gardens (excellent salt tolerance)

• Exposed, windy sites

• Security hedging and boundaries

• Low-maintenance gardens

• Wildlife-friendly gardens

• Poor, sandy, or difficult soils

• Informal hedging

• Cottage gardens

• Romantic, elegant planting schemes

• Foraging gardens (hips for syrups and jellies)

• Fragrance gardens

Foraging & Uses

• Rosehips: Among the largest and easiest to harvest; extremely high in vitamin C

• Uses: Make excellent rosehip syrup, jelly, tea, and wine

• Harvest: Pick after the first frost for best flavour and sweetness

• Preparation: Cut in half and remove irritant seeds and hairs before using

• Yield: One mature plant can produce hundreds of hips

Things to Consider

• Stems are very thorny – plant away from pathways and children's play areas

• Can spread by suckers, forming thickets (great for hedging, less ideal for formal borders)

• Flowers are single (5 petals), not the large, many-petalled blooms of hybrid roses

• May self-seed if hips are not harvested or removed

• Vigorous growth may need controlling in smaller gardens

• White flowers can show rain damage (though they're quickly replaced)

Design Ideas

• White borders: Combine with white foxgloves, delphiniums, and nicotiana for an elegant scheme

• Moonlight garden: Plant with white lilies, white Japanese anemones, and silver-leaved plants for evening fragrance and luminosity

• Coastal planting: Use with sea holly, lavender, and grasses for a naturalistic seaside garden

• Scented hedge: Plant in rows for a fragrant, wildlife-friendly boundary

• Contrast planting: Pair with deep purple plants like Nepeta or dark-leaved heucheras for striking contrast

Companion Plants

Create beautiful combinations with:

• Lavender for complementary fragrance and colour

• Purple sage for foliage contrast

• White geraniums or cosmos at the base

• Silver-leaved artemisia for harmonious tones

• Blue catmint (Nepeta) for soft colour contrast

Please see our bare root plant guides for more information. We've put together a collect of help and advice articles covering what bare root plants are, why they are a good choice, which plants are available bare root, when and where to plant.

Deciduous plants supplied bare root during the dormancy period will not have any leaves at this time; top growth will just be brown and twiggy to start with and will come into leaf in the spring. This is perfectly normal. The plants we supply are healthy will an extensive root system. Please see the final picture for an illustration of how your plants will look when they are delivered.
