Hydrangeas for Estonia: a variety review and how to choose

For our climate, choose a hydrangea by species rather than by the beauty of its flower head: panicle hydrangea (Hydrangea paniculata) and smooth hydrangea (Hydrangea arborescens) bloom on the current year’s shoots and hardly fear an Estonian winter. Bigleaf and oakleaf hydrangeas bloom on last year’s wood — after a harsh February you can be left without flowers. We have reviewed our own range: as of 8 October 2026 the nursery catalogue lists 98 hydrangeas, 83 of them in stock.

What is in our catalogue: the numbers from the review

• Panicle hydrangea (H. paniculata) — 82 listings, 74 in stock. The backbone of the range and the most reliable choice
• Smooth hydrangea (H. arborescens, the Annabelle group) — 13 listings, 7 in stock
• Bigleaf hydrangea (H. macrophylla) — 1 listing, Hi Fire
• Oakleaf hydrangea (H. quercifolia) — 1 listing, Pee Wee
• Climbing hydrangea (H. petiolaris) — 1 listing, currently out of stock

Prices in the catalogue mostly range from 10 to 45 €. The main price factor is container size (the pot volume is shown on the product card), the second is how new the variety is. The same varieties (for example Pixio, Phantom, Petite Star, Wim’s Red, Magical Lime Sparkle) appear in several listings: it is the same variety in different pots.

First decision: species

• Panicle hydrangea — winter-hardy, blooms on new shoots, so it can be pruned hard in spring. Flowers from midsummer to autumn, and the flower heads change colour. Choose it if you want certainty
• Smooth hydrangea (Annabelle) — very winter-hardy, blooms on new shoots, with ball-shaped flower heads. On the old Annabelle variety the large flower heads flop after rain; Strong Annabelle has sturdier stems, and its flower heads reach 30 cm according to the description and do not fall over
• Bigleaf hydrangea — the familiar blue and pink “mopheads”. The colour depends on soil acidity: on acid soil they turn blue, on alkaline soil red or pink. In our climate the buds on old wood get frostbitten, so winter protection is needed. Buy it as an experiment, not as the backbone of the garden
• Oakleaf hydrangea (Pee Wee) — compact, with burgundy leaves in autumn. Blooms on last year’s shoots and needs a sheltered spot and mulch

Second decision: size

Variety size is the main reason a hydrangea gets moved two years after planting. Go by the variety description, not by how the “adult” plant looks at the nursery:

• Large, about 2 m tall and more: Limelight, Kyushu (upright, with narrow creamy cones), Tardiva (blooms late — August to October)
• Compact: Little Lime, Limelight Prime, Little Quick Fire — suitable for small plots and containers
• Dwarf: Bobo (white flowers turn pink, profuse blooming), Little Spooky, Pixio

The sizes in breeders’ descriptions are maximums under good conditions; in the first years the shrub is usually noticeably smaller.

Third decision: colour and bloom time

• Lime-cream, turning pink by autumn: Limelight, Little Lime, Limelight Prime, Magical Lime Sparkle
• White, turning pink or purple by autumn: Tardiva, Kyushu, Grandiflora, Silver Dollar
• Two-tone “strawberries and cream”: Vanille Fraise, Sundae Fraise, Pinky Winky, Wim’s Red (deep red by autumn). Their large flower heads are heavy, and branches may bend after rain
• Early bloomers: Early Harry, Little Quick Fire — they open the season earlier than the others, which suits a short summer

What we noticed while reviewing the catalogue

• 8 panicle hydrangea listings are out of stock (Pinkachu, Sundae Fraise, Pandalus, Fire Light, Fire Light Tiny Bit, Tiny Quick Fire, Quick Fire Fab, Little Lime Punch) — check availability before ordering
• Duplicate names: Wim’s Red, Pixio, Phantom, Petite Star, Samarskaya Lydia, Vesuvio and a few others appear two or three times — by pot size
• Of the smooth hydrangeas, currently in stock are Annabelle, Pink Annabelle, Strong Annabelle, Lime Rickey, BellaRagazza Limetta, Candybelle Bubblegum and Sorbet

Planting in autumn: is it possible

Container-grown hydrangeas can be planted in autumn, as long as the ground is not frozen. Plant, water generously and mulch with peat or bark in a layer of 5–7 cm. Panicle and smooth hydrangeas will root without any trouble; for bigleaf and oakleaf types autumn is riskier, and they are better planted in spring.

Pruning and feeding

• Panicle and smooth hydrangeas: prune in early spring, before the buds open. Shorten panicle hydrangea to 2–3 pairs of buds; smooth hydrangea can be cut low — they bloom on new shoots
• Bigleaf and oakleaf hydrangeas: do not prune in autumn or spring; remove only the winter-killed shoots after the buds open
• Acid soil is needed by all hydrangeas: peat, conifer litter, acid peat substrate. Lime and wood ash must not be added

What not to do

• Do not buy from a photo alone: check the variety’s size and bloom time against the description
• Do not plant a hydrangea in dry sandy soil without peat and watering — the leaves will scorch
• Do not prune bigleaf hydrangeas in spring “like panicle ones” — you will cut off the buds
• Do not add lime or wood ash under a hydrangea
• Do not plant tall varieties with heavy flower heads in a windy spot without support

Frequently asked questions

Which hydrangea should I choose for an Estonian garden?

A panicle hydrangea (for example Limelight, Kyushu, Little Lime) or the smooth hydrangea Strong Annabelle: both are winter-hardy and bloom on new shoots, so they flower even after a cold winter.

Why is my hydrangea not flowering?

Most often the cause is frostbitten buds (on a bigleaf hydrangea), pruning at the wrong time or a spot that is too shady. A panicle hydrangea blooms on new shoots, so this is not a risk for it.

Can the colour of a hydrangea be changed?

Only on a bigleaf hydrangea: the colour depends on soil acidity. Panicle hydrangeas change colour on their own through the season — from cream or lime to pink.

Which hydrangea suits a container?

Dwarf and compact varieties: Bobo, Little Lime, Little Spooky, Pixio, Little Quick Fire. For winter the container needs to be insulated or moved to a cold room.

How long does a hydrangea live?

With proper care, panicle and smooth hydrangeas grow in the same spot for decades. Rejuvenation pruning is done in spring.
