renate steiniger hydrangea

Features and Appearance

Hydrangea ‘Renate Steiniger’ is prized for its generous, globe-shaped flower heads that can reach up to 20cm across. In acidic soils, these hydrangea blooms display a rich, true blue that stands out beautifully. In more neutral or alkaline soils, the flowers can become a striking lavender. The lush green foliage provides an attractive backdrop throughout the growing season and turns shades of yellow in autumn.

As a vigorous and long-flowering shrub, Renate Steiniger hydrangea can reach heights and widths of 1.5 metres, making it ideal for filling space without looking overpowering. The flowers are long-lasting both on the shrub and in arrangements—perfect for cutting and bringing indoors.

How to Grow Renate Steiniger Hydrangea

Hydrangea ‘Renate Steiniger’ is easy to grow with just a few simple care steps. For the best blue colour, plant in moist—but well-drained—soil enriched with organic matter. Partial shade is ideal, ensuring the plant receives morning sun and is protected from the harshest midday rays, helping to preserve those vivid blue hues. Water regularly during dry spells, especially in the first season after planting.

To encourage even larger, brighter blooms, add aluminium sulphate to the soil to maintain acidity. Prune old wood after flowering to keep the shrub compact and healthy.

Landscaping Uses

The Renate Steiniger hydrangea is perfect for borders, cottage gardens, and shade gardens. Mass plantings under deciduous trees create a billowing tapestry of blue in summer, while single specimens work beautifully in large pots or by entrances. Pair it with other hydrangeas for a dynamic, textural display—varieties such as Hydrangea Ayesha, with its unusual cupped petals, or the romantic white Hydrangea Bridal Bouquet add gorgeous contrast.

Companion Plants

Hydrangeas like ‘Renate Steiniger’ shine alongside shrubs that complement their foliage and flowers. Consider mixing with Azalea Dr Glaser for spring colour, Buddleia davidii for butterfly-friendly blooms, or Viburnum opulus Notcutt's Varieity (Snowball Bush) for dramatic spring and summer interest. For a striking hydrangea pairing, try Hydrangea Blue Deckle or the panicle-type Hydrangea paniculata Grandiflora.
