Three decades of family team wisdom on what genuinely grows where across Hampshire’s surprisingly varied gardens.
Hampshire is geographically smaller than people realise — you can drive from one end to the other in 90 minutes — but the planting conditions vary enormously across that distance. Chalk downs above Winchester, heavy clay around Romsey, sandy coastal plots on Hayling, acidic woodland soil in the New Forest fringe, exposed Solent gardens in Gosport — each one needs a different planting approach.
Here’s what our family team has learned about Hampshire planting after 30 years and 500+ projects.
Alkaline / chalky / free-draining
Winchester gardens (especially north of the city, into the downs and villages like Sparsholt and Crawley) sit on chalk. That means alkaline, free-draining soil that warms up early in spring — brilliant for Mediterranean-style planting and traditional English borders, terrible for acid-lovers.
Plants that thrive: Lavender, rosemary, salvias, achillea, verbascum, scabious, Verbena bonariensis, sedum, allium, foxgloves, hellebores, clematis, climbing roses, philadelphus, viburnum, choisya, ceanothus.
Plants to avoid: Camellias, rhododendrons, azaleas, blueberries, pieris — anything labelled as needing ‘ericaceous’ or ‘acid soil’ will yellow and sulk on Winchester chalk.
Heavy clay / moisture-retentive
Romsey, Braishfield, Awbridge and the Test Valley villages sit on heavy clay. Brutal in dry summers (cracks open up), waterlogged in winter, but extraordinarily fertile when worked properly.
Plants that thrive: Hydrangeas, astilbe, persicaria, hostas, ligularia, miscanthus, rudbeckia, helenium, sanguisorba, geraniums, day lilies. Trees: oak, ash, alder, willow.
Make life easier with: Annual mulch with composted bark, raised beds in waterlogged spots, planting in spring after the clay has warmed and drained.
Sandy / wind-exposed / mild
Coastal Hampshire gardens get the south-westerly straight off the Solent. Salt air, wind, but mild winters (rarely a hard frost). Soils tend to be sandy-loam, free-draining, easy to work.
Plants that thrive: Salt-tolerant Mediterranean planting — santolina, phlomis, cistus, eryngium, achillea, agapanthus, escallonia, hebes, olearia, tamarix, sea kale, sea holly. Tender plants (cordyline, phormium, banana) often survive coastal Hampshire winters that would kill them inland.
Watch out for: Wind burn on broadleaf evergreens, especially in their first winter. Stake young trees properly — coastal wind is no joke.
Acidic / sandy / heath-like
New Forest soils are typically acidic, sandy, and low in nutrients. Beautiful for woodland and heathland planting; less forgiving of demanding cottage garden plants.
Plants that thrive: Camellias, rhododendrons, azaleas, pieris, magnolia, blueberries, heathers, gorse, foxgloves, bracken (controlled), ferns, woodland anemones, bluebells.
Mixed / sometimes chalky, sometimes loamy
Petersfield itself sits in the gap between the chalk South Downs and the greensand below — meaning soils vary even within the town. Test your soil before designing the planting.
Generally reliable: Traditional English border plants — geraniums, lavender, salvias, foxgloves, alchemilla, achillea, roses, hydrangeas (in greensand pockets).
If a plant can survive a stray football, it earns its place in a family garden. Lavender bounces back. Ornamental grasses bend and rise again. Lamb’s ear is irresistible to small fingers and tough as old boots.
For a low-maintenance Hampshire border: 60% structural evergreens (box, hebe, sarcococca, choisya), 30% reliable perennials, 10% seasonal annuals or bulbs. The structure keeps it looking intentional even in November.
The single biggest planting mistake we see in Hampshire gardens is spring planting followed by a dry summer. Autumn-planted shrubs and perennials have all winter to establish roots before the dry season. They’ll outperform spring-planted equivalents within a single year.
Every garden design we produce includes a bespoke planting plan tailored to your soil, aspect, microclimate and family’s appetite for gardening. Or if your design’s already done and you just need the planting sorted, ask about our standalone planting plan service.
