Elaeagnus oleaster for Deal and Walmer: the four varieties and which position each one suits.
Ask most people what they know about elaeagnus and they will say it is a bit silvery and smells surprising in autumn. Both are true. What is less well known is that the species type, Elaeagnus x ebbingei, is one of the most salt-tolerant large shrubs you can plant on the CT14 seafront, and that the four varieties grown as hedging in UK gardens behave differently enough that the wrong one in the wrong position can leave you with a straggly, half-burned screen where you expected a dense wall of silver-green.
Elaeagnus is a genus of around 90 species, mostly from Asia. The two most commonly planted for hedging in British gardens are the hybrid E. x ebbingei (a cross between E. macrophylla and E. pungens) and E. pungens itself. Both are RHS H5, meaning they will survive down to minus 15°C, which is comfortably colder than anything the Kingsdown frost hollow throws at them in a normal winter. On the CT14 coast the limiting factor is not cold but salt wind, and that is where E. x ebbingei and its varieties separate out clearly.
I see it on a lot of Walmer Esplanade and seafront jobs: someone has planted the variegated 'Gilt Edge' because it looks attractive in the pot, and five years later it is performing well enough in the sheltered back garden but has burned on its exposed corner. The species type would have handled that corner without fuss. The table below separates the four varieties I regularly encounter on CT14 jobs by the criteria that actually matter for the position.
| Variety | Leaves | Growth rate | Ultimate height | Salt tolerance | Best CT14 position | Pruning window |
|---|---|---|---|---|---|---|
| E. x ebbingei (species type) | Dark green, silver beneath, no variegation | 40–60 cm/yr | 3–5 m | Very high: first-line exposed seafront | Walmer Esplanade first line, Kingsdown shore boundaries | May–June; light trim August optional |
| E. x ebbingei 'Gilt Edge' | Dark green with broad gold margins (RHS AGM) | 30–40 cm/yr | 3–4 m | Medium: sheltered coastal or second-line | Sheltered Walmer garden, Mill Hill second-line boundary | May–June |
| E. x ebbingei 'Limelight' | Green with yellow central blotch | 30–45 cm/yr | 2.5–3 m | Medium to high: tolerates salty breezes with shelter | Second-line Deal seafront, sheltered Kingsdown gardens | May–June |
| E. pungens 'Maculata' | Gold central blotch, deep green margins, spiny stems | 20–30 cm/yr | 2–3 m | Medium: sheltered boundaries, not first-line exposed | Internal garden boundary in Deal or Walmer, walled courtyard | Late summer (August–September) |
Before you start cutting: safety note
E. pungens and its cultivars have sharp spines at branch axils. Heavy gloves are essential for pruning work and they will find gaps in thin leather gloves. Eye protection is standard for any powered-trimmer work on this species. The species-type ebbingei and its cultivars ('Gilt Edge', 'Limelight') are less spiny but still produce occasional sharp points on older stems. For hedge-height work over 1.8 m, a pole trimmer is the safer option: avoid standing a ladder against the face of a mature elaeagnus. As with all powered hedge cutting, use an RCD adaptor on any corded trimmer and work with the extension cable laid back along the hedge, not looped underfoot.
The species type: what earns it a place on the first line.
The straight E. x ebbingei, without any named cultivar suffix, is the workhorse. The leaves are unremarkable close-up: dark glossy green on top, silver-speckled and slightly lighter beneath. At any distance beyond a few metres the whole hedge looks silver-grey in certain light, which is pleasing on a seafront boundary and distinctive in autumn when the October flowers are open.
Those flowers are worth planning for. They are small, creamy-white and almost completely hidden inside the foliage. What reaches you first is the scent: heavy, sweet, a bit like vanilla and freesia mixed. On a still October afternoon on the Walmer Esplanade, a mature ebbingei hedge in full flower is one of the better surprises the CT14 coast offers. The scent travels, and pollinators find it well before the flowers are visible.
Growth rate is 40–60 cm per year once established, which on CT14's fast-draining shingle and alluvium ground means it needs attention in its first two summers. I water new elaeagnus plants the same way I water new griselinia: daily in dry spells for the first eight weeks, then twice-weekly until the end of the first September. After that it looks after itself almost entirely. By year three it is a solid screen.
Spacing for a hedge: 60–90 cm between plants. I use 70 cm as a default on most Deal and Walmer jobs. Closer spacing on a fully exposed Kingsdown shore boundary where you need the hedge closed faster; wider spacing is a waste because elaeagnus does not extend sideways as willingly as griselinia to fill a gap.
'Gilt Edge': the decorative choice and why it needs a sheltered spot.
'Gilt Edge' holds an RHS Award of Garden Merit and it deserves it in the right position. The gold-margined leaves are genuinely attractive, and in winter when nothing else is moving in the garden a mature 'Gilt Edge' hedge has real presence. But the gold leaf margins are the giveaway: variegated forms of any plant carry less chlorophyll per unit of leaf area, and that translates to slightly reduced vigour and slightly reduced salt and wind hardiness compared to the plain species type.
On a sheltered back-garden boundary in Walmer or on a second-line Deal plot, 'Gilt Edge' is an excellent choice. On a fully exposed seafront first line at Walmer or on a Kingsdown shore boundary, I would not plant it. Salt wind and spray discolour the gold margins and eventually cause dieback on exposed shoots. The hedge can survive but it looks stressed and never reaches its potential. Plant the species type there and keep 'Gilt Edge' for positions where it can do what it does well.
'Limelight': the compact variegated form.
'Limelight' has a yellow central blotch to the leaf rather than a gold margin, and it grows more compactly than both the species type and 'Gilt Edge', topping out at around 2.5–3 m rather than 3–5 m. That lower ultimate height is sometimes exactly what a Deal garden needs. A back boundary in one of the Victorian terrace gardens behind the seafront properties in Lower Walmer does not always need a 4 m elaeagnus blocking the light. 'Limelight' gives you the salt-tolerant, dense evergreen screen at a height you can manage year to year without a major reduction cut every other season.
It flowers in October like the rest of the ebbingei group, which means the scent and the pollinator value come with it. For an enclosed Walmer garden or a sheltered Mill Hill boundary plot, 'Limelight' is a sensible call.
Pungens 'Maculata': slow, spiny and underrated for winter colour.
E. pungens 'Maculata' is the variety most people have actually seen, because it appears frequently in supermarket car parks and municipal plantings. The gold central blotch is vivid and the margins are dark, glossy green. It is slower than ebbingei: 20–30 cm per year is a realistic expectation. But it is also more tolerant of shade than the ebbingei forms, which matters in a walled courtyard or on a north-facing section of a Victorian terrace in central Deal.
It has one characteristic the ebbingei group does not share: the stems are genuinely spiny, with sharp points at the branch axils. That makes it a reasonable low-level security hedge as well as a screen, but it also means heavy gloves for every pruning job and a blade-sharpening session afterwards. The stems blunt blades faster than griselinia or privet.
Pruning timing for 'Maculata' is different from the ebbingei group: late summer, August into September, rather than the May to June window I use for ebbingei. This is partly because it flowers on old wood in autumn (like ebbingei) and you want to avoid cutting away the flowering spurs, and partly because it produces a flush of growth in midsummer that is worth letting harden off before you trim.
Cutting elaeagnus during the nesting season: check before you start
Under the Wildlife and Countryside Act 1981, section 1, it is an offence to intentionally take, damage or destroy an active wild bird's nest. The nesting season runs from 1 March to 31 August. Elaeagnus hedges on the CT14 coast provide good nesting cover, particularly for blackbirds and sparrows, and the species type's dense interior is exactly what robins and dunnocks prefer. The recommended May–June pruning window for ebbingei falls squarely inside the nesting season.
Before cutting between 1 March and 31 August, walk the full length of the hedge looking and listening for signs of nesting: birds flying in and out, alarm calls, visible nest material. If you find an active nest, leave that section alone until the young have fledged, which is typically 14–21 days after hatching. The penalty is an unlimited fine and up to six months in prison. The safe alternative is to delay the first trim to September, after the nesting season closes, accepting that the hedge will be slightly less tidy through summer. On most CT14 jobs I discuss this tradeoff with the owner and most prefer the September-only approach once they understand the legal position.
Elaeagnus against griselinia and escallonia: which species for which CT14 position.
On the CT14 coast these three species cover most of the same ground. All three are evergreen, all three handle salt wind, and all three appear regularly on Walmer Esplanade and Kingsdown shore boundaries. The choice between them is usually about growth form, cutting timing and how much the maintenance burden matters to the owner.
| Species | Salt tolerance (exposed first-line) | Growth rate (established) | Winter screening | Wildlife value | Cuts per year | Safe cut window |
|---|---|---|---|---|---|---|
| Elaeagnus x ebbingei (species type) | Very high: handles exposed seafront first line | 40–60 cm/yr | Excellent: fully evergreen, dense | Good: Oct–Nov flowers for pollinators; spring berries for birds | 1–2 (May–June; optional light trim August) | May–June or September onwards |
| Griselinia littoralis (species type) | Very high: the CT14 default for exposed first line | 30–50 cm/yr | Excellent: apple-green, dense | Low: minimal berry or flower value | 1–2 (August preferred; avoid November) | Late July–August |
| Escallonia macrantha (species type) | High: handles seafront well once established | 30–50 cm/yr | Good: evergreen but less dense than the above two | Excellent: June–August flowers for bees; some berry | 1–2 (after flowering July–August; light trim spring optional) | July–August post-flower |
The practical difference on a Walmer Esplanade job: griselinia is the default because most owners on that stretch already have it and it has a track record in the position. Elaeagnus x ebbingei is an equally capable alternative, particularly if the owner wants the October fragrance or the spring berry crop for birds. Escallonia is the choice where the flower display matters more than maximum density.
One thing elaeagnus offers that neither griselinia nor escallonia does: the October and November fragrance. On a coastal garden where you are sitting outside on a still autumn afternoon, a 3 m elaeagnus hedge in flower is a genuinely different experience from a plain griselinia of the same height. It is not the obvious practical consideration, but it is a real one and owners who have it tend to mention it.
Elaeagnus also berries in spring, producing small orange-red fruits that birds take. They are not as significant a berry crop as hawthorn or blackthorn, and you would not choose elaeagnus for wildlife value alone, but the bees work the October flowers hard. For a Kingsdown garden adjacent to the Dover to Kingsdown Cliffs SSSI, where every bit of additional pollinator and bird food matters, that is worth noting.
Pruning elaeagnus: one cut or two, and why the timing matters.
For the ebbingei group (species type, 'Gilt Edge', 'Limelight'), the primary cut is in May or June, after the fragrant October flowers have set and developed any berries, and before the plant puts on its main flush of new growth. A May cut means the fresh new shoots close the hedge over by July. A June cut is slightly later but still gives the hedge the whole summer growing season to recover.
A second light trim in late August or early September is optional and cosmetic. It tidies the season's extension growth without removing the branch structure. On a formal boundary hedge you want to look neat, I do this as a matter of course. On a looser windbreak hedge where density matters more than tidiness, I skip it.
For 'Maculata' (E. pungens), as noted, the timing shifts to August and September. If you cut 'Maculata' in May you are removing the flowering spurs and losing the autumn scent. There is no structural reason not to cut it in spring, but on a hedge kept partly for the autumn flower display it is worth waiting.
If the hedge has become significantly overgrown, hard renovation of elaeagnus is possible but takes two or three seasons. Cut one face hard (back to old wood) in late winter, leave the rest alone, and let it regenerate over the following growing season before cutting the second face the following February. Unlike leylandii, elaeagnus will regenerate from old brown wood. I have brought back a 4 m wide ebbingei hedge on a Walmer Esplanade property to a manageable 1 m width over three seasons without losing the plant.
