Which are the 5 RHS gardens?

The Royal Horticultural Society operates five flagship gardens across England, each with its own character and regional focus. Five gardens, one pattern: they all serve as living showcases for horticulture, but each caters to a different part of the country and a different gardening climate.

RHS Garden Wisley – the flagship garden in Surrey

Described as the flagship garden of the Royal Horticultural Society (Visit London (tourism authority for London))
One of the largest plant collections in the world (Visit London (tourism authority for London))

Located in Salford, Greater Manchester
Largest RHS garden at 154 acres

The upshot

A first-time visitor to RHS gardens faces a choice between the traditional grandeur of Wisley and the modern innovation of Bridgewater. Wisley offers the most curated collection of rare plants; Bridgewater offers the most space and a community-oriented atmosphere.

Bottom line: The pattern: each garden reflects its region’s climate and gardening tradition. Visitors in the south-east gravitate toward Wisley or Hyde Hall, northerners have Harlow Carr and Bridgewater, and the south-west is covered by Rosemoor. For the RHS member, the real value is not just one garden but the freedom to explore all five without paying again.

What is the Irish equivalent of RHS?

Gardeners in Ireland wondering about a similar organisation have a clear counterpart. The Royal Horticultural Society of Ireland (RHSI) operates independently from the RHS but shares its core mission of promoting horticulture.

Royal Horticultural Society of Ireland (RHSI)

RHSI is the Irish equivalent of RHS (RHS (official membership page))
RHSI has its own partner garden scheme with 63 gardens across Ireland
RHS and RHSI are independent but share a similar mission

RHSI Partner Garden Scheme (63 gardens)

RHSI members can access 63 partner gardens across Ireland
The scheme mirrors the RHS partner garden model

Differences between RHS and RHSI membership

RHS membership costs £79.99 annually (RHS (official membership page))
RHSI membership pricing and benefits differ — check RHSI website for current details
RHS members cannot use their membership at RHSI partner gardens, and vice versa

The catch

UK-based RHS members visiting Ireland will find no reciprocal access to RHSI partner gardens. Irish gardeners considering RHS membership should weigh the distance to the five English flagship gardens against the cost of joining RHSI for local access.

The implication: for Irish residents, RHSI membership is usually the practical choice, while UK-based gardeners with an interest in Irish gardens may need both memberships — a rare case where the two societies do not overlap.

Which RHS garden is the best?

Five flagship gardens, all different. One question: which one should you pick? The answer depends on what you value — size, events, accessibility, or beauty.

Criteria for ‘best’: size, events, accessibility, beauty

Size: Bridgewater is the largest at 154 acres; Wisley is the most established at 240 acres
Events: Wisley hosts the most flower shows and plant fairs
Accessibility: All gardens have parking, cafes and accessible paths, but check individual websites for specific access details
Beauty: Subjective, but Wisley’s glasshouse and Rosemoor’s rose garden are frequently praised

Comparison table of the five gardens

Five gardens, one decision framework: location determines convenience, and size determines how much you can see in a day.

Garden	Location	Acres	Opened	Signature feature
RHS Garden Wisley	Surrey	240	1900s	Wisley Glasshouse, large plant collections
RHS Garden Rosemoor	North Devon	65	1988	Rose garden, arboretum
RHS Garden Harlow Carr	Yorkshire	68	1949	Woodland, alpine garden
RHS Garden Hyde Hall	Essex	360	1993	Dry and wet gardens
RHS Garden Bridgewater	Salford, Greater Manchester	154	2021	Historic walled garden

Upsides

Free entry to all five flagship gardens plus over 220 partner gardens
Members receive The Garden magazine (valued at £81)
Reduced-rate tickets to RHS Flower Shows and events
Free parking at flagship gardens

Downsides

Annual cost of £79.99 (individual) may not pay off for occasional visitors
Partner gardens have restricted opening days and may exclude guests
No reciprocal access with RHSI in Ireland
Dogs generally not allowed in flagship gardens

Visitor reviews and expert opinions

RHS Garden Wisley is often considered the flagship and most visited (Visit London (tourism authority for London))
RHS Garden Bridgewater is the newest and largest at 154 acres
Best depends on personal preference: Wisley for tradition, Bridgewater for innovation

The trade-off

A Wisley-based membership delivers the richest plant collection, but a Bridgewater-based membership gives you the newest garden with the most room to explore. For the casual visitor, Bridgewater’s modern design may feel more engaging; for the dedicated horticulturist, Wisley’s collection is unmatched.

Bottom line: What this means: the ‘best’ RHS garden is the one closest to you or the one that matches your gardening interest. If you want the widest variety of rare plants, head to Wisley. If you want the newest and most spacious garden, choose Bridgewater.

Which is the newest RHS garden?

One garden stands out for its recent addition to the RHS portfolio. RHS Garden Bridgewater, opened in 2021, is the newest flagship garden and also the largest.

RHS Garden Bridgewater opening in 2021

Opened in 2021 (RHS FAQ Search)
Located in Salford, Greater Manchester
Largest RHS garden at 154 acres

Location: Salford, Greater Manchester

Accessible from Manchester city centre
Parking available on site

Key features: 154 acres, historic walled garden, community focus

154 acres of gardens and parkland

Community-focused design with family-friendly areas

Why this matters: for northern gardeners, Bridgewater represents the first RHS flagship garden in the North West, filling a long-standing gap in RHS coverage. Visitors from Liverpool, Manchester and Leeds now have a flagship garden within an hour’s drive.

What are RHS partner gardens and how can I visit them?

Beyond the five flagship gardens, the RHS offers access to over 220 partner gardens across the UK and overseas. These are privately owned gardens that open to RHS members on selected days.

Bottom line: RHS membership is about access to 225+ gardens, not just five. For the UK-based gardener, the partner garden network effectively doubles the value of membership. For the occasional visitor, paying per visit may be cheaper — check individual garden prices on the RHS website.

The catch: partner garden access is not universal. Each garden sets its own rules on opening days, guest entry, and seasonal closures. A member planning a road trip should verify opening times before travelling, as some gardens may require advance booking.

Frequently asked questions

How long does it take to visit each RHS garden?

Are there discounts for seniors or families?

RHS offers a Joint Membership for two adults at £119.99 annually, which includes free entry for up to four children. Individual membership costs £79.99.

Can I bring my dog to RHS gardens?

Dogs are generally not permitted in RHS flagship gardens, except for assistance dogs. Some partner gardens may allow dogs on leads — check individual garden policies before visiting.

Do I need to book tickets in advance?

Advance booking is recommended for flagship gardens, especially during peak season and special events. Partner gardens may require pre-booking or have limited entry slots. Check the RHS website for each garden’s booking policy.

What is the best time of year to visit?

Spring (April–May) offers peak blooms including rhododendrons and azaleas. Summer (June–August) provides full garden displays and outdoor events. Autumn (September–October) is ideal for foliage colour at Wisley and Bridgewater.

Are there cafes and restaurants at RHS gardens?

All five flagship gardens have on-site cafes and restaurants. Wisley has a large restaurant and plant shop. Partner gardens may have limited or seasonal catering.

How do I find RHS partner gardens in Scotland?

Is there parking available at RHS gardens?

All five flagship gardens have free parking for members and visitors. Partner gardens may have limited or paid parking — check individual garden websites.

For the UK-based gardener who visits at least three gardens per year, RHS membership at £79.99 pays for itself. The five flagship gardens offer distinct experiences, and the 220+ partner network turns membership into a travel pass for garden lovers. For the occasional visitor, the choice is clear: buy a day ticket for the garden you want to see, or commit to membership and explore the full network. For northern gardeners, Bridgewater’s opening in 2021 finally provides a flagship garden within reach — a change that makes membership more attractive than ever.
