Escallonia

Escallonia rubra

The standard seaside hedge along the western coasts, glossy-leaved and evergreen, with small pink or red flowers through the summer that bees work steadily. It shrugs off salt wind in a way almost nothing else evergreen does, and is correspondingly less happy in a cold inland garden.

Position: Full sun or Partial shade
Water: low demand
Drainage: Free-draining, Moisture-retentive
Grows to: 200–350 cm × 150–300 cm
Hardiness: H4
Flowers: June to September

Escallonia’s year

Resolved for United Kingdom (general). Every window is stored against a climate event rather than a date, so a late frost pocket runs later than the band shows. What else August calls for.

On your soil

Computed by comparing this plant's recorded requirements against each soil's recorded characteristics. A recorded horticultural fact overrides the comparison where GrowingHQ holds one.

Soil	Verdict	Why
Heavy clay	Works, with one condition	Escallonia will crop on heavy clay, but one thing has to be dealt with first. It needs ground that drains, and this soil holds water. A plant that stays in the ground through winter with its roots in cold, saturated soil rots — which is what kills most of what fails on heavy ground, rather than the cold.Improve the drainage before planting — a raised bed, or bulky organic matter worked in over several seasons. Do not add sand to clay in small quantities; it makes the problem worse.
Sandy	Prefers this soil	Sandy suits Escallonia as it stands: The pH suits it: it wants 5.5 to 7.8, and this soil is in that range. The free drainage is exactly what it wants. Sandy soil is among the soils it is recorded as suiting. It stands dry conditions better than most, which this soil will test.

Measured centre to centre. Plants set closer than this compete for light and water long before they look crowded, and the crowding cannot be undone once they are in.

Habit and ultimate size

What the plant becomes, rather than what it is when you buy it. The gap between the two is where most planting mistakes live.

Cutting it back. Breaks from old wood, so an overgrown hedge can be reduced hard in mid-spring at the cost of a year's flowers. This tolerance is much of why it is the standard coastal hedge — it recovers from wind damage as readily as from the shears.

Where and how you can grow it

Each way of growing is assessed separately, and “not assessed” is a real answer rather than a gap we have filled in with a guess.

Growing it

PruningAs a hedge, clip after flowering rather than in spring — it flowers on the previous year's wood, so a spring cut removes the display. It breaks from old wood, so an overgrown plant can be reduced hard in mid-spring and will recover, at the cost of a year's flowers.
PlantingChoose it for a coastal boundary and something else for a cold inland one. In an exposed garden in the north or east it is regularly cut back by winter and never makes the dense hedge it is bought for.
WateringWater new plants through their first two summers, particularly in a hedge where they are competing with each other from the start, and then not at all. Escallonia is a tough coastal evergreen that copes with wind and salt and dry soil once its roots are down. Autumn planting is a real advantage for a hedge: the plants root over winter and meet their first summer established rather than being kept going with a hose along the whole run. It dislikes waterlogged ground more than dry ground.
FeedingA general-purpose feed and a mulch in spring is enough, and is worth giving to a clipped hedge, which is being asked to regrow what you cut off every year and is the one situation where an escallonia is genuinely working for its living. A free-standing shrub in reasonable soil needs nothing. Avoid high-nitrogen feeds late in the season: soft autumn growth on an evergreen is what gets scorched by cold winds in an exposed position.

The bud you cut to becomes the new shoot, and it grows in the direction it points — which is why an outward-facing bud opens the plant up and an inward-facing one crosses the middle.
