💙 9 to 15 blue umbels with curled and rolled petals • 🌿 Flowering from June to September • 🌤️ Partial shade or soft light • ❄️ Very hardy • 📏 H50 cm | Pot Ø23 cm
Hydrangea 'Curly Wurly Blue' is a lacecap hydrangea native to the Netherlands, selected for its large decorative flowers with a unique profile: their petals curl and bend on themselves, creating an unusual texture very different from all classic hydrangeas. The flat umbels feature a dense core of blue-green buds surrounded by a crown of large blue-white flowers with curved spoon-shaped petals. Delivered with 9 to 15 heads per plant, it is both denser and more original than standard lacecaps on partially shaded balconies, terraces, and gardens.
Very free-flowering, very hardy and easy to care for, its blue color depends, like all hydrangeas, on the acidity of the substrate. It is one of the most original summer-flowering shrubs in the catalog.
Which hydrangea to choose?
Verdeia offers several hydrangeas with distinct shapes and colors. Here is how to place the 'Curly Wurly Blue' among the varieties in the catalog:
- Hydrangea 'Curly Wurly Blue' (this plant) — blue lacecap umbels with curled and rolled petals, 9 to 15 heads. The most original and unusual variety in the catalog.
- Hydrangea Teller 'Nizza Blue' — blue lacecap umbels with classic flat petals. The traditional blue version of the Teller series.
- Hydrangea Teller 'Benxi' — white lacecap umbels with flat petals. The choice for a very elegant white in the same size.
- Hydrangea Early Blue — large, intense blue mopheads, early flowering. The choice for a dense, very full blue mophead.
- Hydrangea arborescens 'Strong Annabelle' — very large white flower heads on sturdy stems. The choice for a generous, pure white with strong structure.
- Hydrangea petiolaris — climbing hydrangea with flat white umbels, self-clinging on walls. The only climbing hydrangea in the catalog.
Exposure & location
The 'Curly Wurly Blue' appreciates soft light to partial shade — its blue color is more intense and more stable away from the scorching afternoon sun. The recurved texture of the petals is especially visible in low morning or evening light, which reveals the relief of each flower better than the overhead midday sun.
- Exposure: partial shade or soft light — ideally east or northeast facing, sheltered from the afternoon sun.
- Location: north or east-facing balcony, shaded terrace, garden under partial cover.
- Soil: rich, humus-rich, moist and acidic — ideal pH between 5 and 6 for an intense and stable blue.
- In a pot: acidifying substrate for hydrangeas — always water with rainwater or demineralized water.
The curved texture of the 'Curly Wurly' petals is especially enhanced in a place with changing light — a balcony that receives morning sun then moves to shade in the afternoon is the ideal location to appreciate both the color and the unusual shape of the flowers.
Watering & maintenance
Like all hydrangeas, the 'Curly Wurly' is very thirsty in a pot. Its care is the same as for other lacecap hydrangeas — the main point to watch is the quality of the water you use, which directly affects the blue color of the flowers. A careful restart in spring with a dedicated acidifying hydrangea fertilizer in March ensures dense flowering and a stable blue.
- Watering: abundant and regular — the soil must never dry out completely; water exclusively with rainwater or demineralized water.
- Pruning: only in spring — remove old dry flower heads above the first strong bud; never prune green wood.
- Fertilizer: acidifying hydrangea fertilizer in March and June — a blueing fertilizer strengthens and stabilizes the blue color.
- Repotting: every 2 years in spring with acidifying substrate for hydrangeas.
- Wintering: very hardy in open ground; in a pot, protect the container from frost or move it to a frost-free space.
Keep the dry flower heads all winter — they protect the flower buds from frost and are particularly decorative on the 'Curly Wurly', whose curled, dried petals create a very elegant sculpted effect under frost.
Decor ideas & plant combinations
The curled texture of the 'Curly Wurly Blue' makes it a standout plant that holds its own in a beautiful pot — but it also works very well in a hydrangea arrangement for a lush, original terrace.
- For a lacecap trio in three very complementary textures, the Hydrangea Teller 'Nizza Blue' and the Hydrangea Teller 'Benxi' in white complete the 'Curly Wurly' — same lacecap format, three distinct petal textures (curled, flat blue, flat white), for a coherent and very sophisticated arrangement.
- For a very spring-like blue and pink combination, the Rhododendron 'Bollywood', pink and variegated, blooms in April–May before the hydrangea takes over in June — these two partial-shade shrubs follow on from each other for a terrace in bloom without interruption from winter to early autumn.
- For an additional evergreen backdrop all year round, the Viburnum tinus, evergreen and dark green, bears white-pink flowers in winter when the hydrangea has finished blooming — the two shrubs take turns throughout the year with complementary palettes.
- To enhance the curled texture in a textured pot, the Capi Nature Groove taupe pot in ribbed recycled material echoes the texture of the 'Curly Wurly's' recurved petals — two ribbed surfaces, one mineral, the other floral, in a matte and very natural pairing.
Photographed up close, the 'Curly Wurly Blue' reveals an almost geometric floral architecture that most people don’t suspect — place it in a space where it can be observed closely to appreciate the complexity of its curved petals.
Verdeia tips
- Water only with rainwater or demineralized water: hard tap water gradually neutralizes the acidity of the substrate and turns the blue-white flowers pink — collect rainwater or use demineralized water for all watering to keep the blue color stable season after season.
- Add a blueing fertilizer at planting: aluminum sulfates (blueing fertilizer for hydrangeas) directly enhance the blue color of the flowers by acidifying the substrate and making aluminum available — applying it in spring and after the first flowering is the most effective way to stabilize and intensify the blue.
- Keep the dry flower heads until spring: they protect the flower buds from frost and create a particularly original winter decoration on the 'Curly Wurly' — their dried and curved petals create a very graphic sculpted effect that even gardeners who didn’t like keeping faded flowers appreciate on this variety.
