What are the 5 RHS Gardens?

The five flagship RHS gardens are spread across England, each with its own character. Here’s what you need to know.

What are the main RHS gardens?

The main RHS gardens are Wisley, Harlow Carr, Hyde Hall, Rosemoor, and Bridgewater.

RHS Garden Wisley – flagship garden in Surrey

RHS Garden Bridgewater – newest garden in Salford

• Key feature: Walled garden, community outreach

Here is a direct comparison of the five flagship gardens.

The implication: if you’re choosing which garden to visit first, size and signature features are the main differentiators. Wisley remains the most visited, drawing around 1 million visitors each year according to the Royal Horticultural Society (the UK’s leading gardening charity).

Which RHS garden is the best?

There’s no official “best” from the RHS, but different gardens appeal to different visitors. Here’s how they stack up.

Criteria for ‘best’ – size, facilities, plant collections

• Wisley is often considered the best for plant diversity.
• Harlow Carr is top for alpine and woodland gardens.
• Hyde Hall offers the largest area for walking and wildflower meadows.

Which is the biggest RHS garden?

RHS Garden Hyde Hall in Essex is the largest at 360 acres, followed by Wisley at 240 acres.

Visitor numbers and awards for each garden

Wisley attracts roughly 1 million visitors annually, making it the busiest RHS garden. Harlow Carr and Hyde Hall each draw around 300,000–400,000, while Rosemoor and Bridgewater see fewer but growing numbers.

Family-friendly features and seasonal highlights

• Bridgewater has a dedicated children’s play area and community garden.
• Hyde Hall’s wildflower meadow blooms in summer.
• Harlow Carr offers seasonal kitchen garden tours.

The catch: there is no single best garden, but matching the garden’s strengths to your interests is the key.

What is the Irish equivalent of RHS?

Ireland has its own horticultural society — the Royal Horticultural Society of Ireland (RHSI) — which is entirely separate from the UK’s RHS.

Royal Horticultural Society of Ireland (RHSI)

• Founded in 1988 as a separate charity.
• Runs its own partner garden scheme with 63 gardens across the island of Ireland (the RHSI Partner Gardens page (the Irish gardening charity)).

RHSI partner garden network (63 gardens)

The RHSI describes its partner garden scheme as “63 varying sized, prestigious gardens throughout the island of Ireland” (the RHSI Partner Gardens page (the Irish gardening charity)). Note that another RHSI page mentions 60, indicating a possible update mismatch.

Differences between RHS and RHSI membership

• RHS membership does not automatically grant entry to RHSI partner gardens.
• RHSI membership is separate and costs less (around €35 annually as of 2025).
• RHS members can visit the five flagship gardens for free, but not the Irish partner gardens unless they have RHSI membership or the garden participates in the RHS partner garden scheme (which a few do).

The catch: if you’re a UK RHS member heading to Ireland, don’t assume free entry. Check the garden’s policy — many RHSI partner gardens require RHSI membership or a separate fee.

RHS partner gardens list and map

The RHS partner garden network extends well beyond the five flagship gardens — over 240 independent gardens across the UK and overseas offer free entry to RHS members at selected times.

How to access the RHS partner gardens list (PDF)

The RHS provides a downloadable PDF list of all partner gardens on its partner gardens finder page (the UK’s leading gardening charity). It’s updated annually, though some gardens may have individual opening times.

Interactive map of RHS partner gardens

The RHS website does not currently offer an interactive map with price filters, but third-party sites like Visit Gardens (a UK garden directory) list many partner gardens with location pins.

RHS partner gardens near me – search tips

• Use the RHS finder and filter by region.
• Check individual garden websites for exact free-entry days (e.g., Backhouse Rossie Estate Walled Garden (a private RHS partner garden in Scotland) offers free entry on Fridays).
• For northern Ireland, see our National Trust Near Me: Verified Guide to Northern Ireland Properties for more garden options.

The pattern: always verify individual garden policies before visiting.

Confirmed facts and what’s still unclear

Confirmed facts

• RHS members get free entry to all five RHS gardens.
• The Royal Horticultural Society of Ireland (RHSI) is a separate organization.

• Exact entry fees for non-members vary by season and garden.
• Some RHS partner gardens may have restricted opening hours.
• The exact number of RHSI partner gardens is inconsistently reported (63 vs 60 on different RHSI pages).

“RHS Partner Gardens are over 240 independent gardens in the UK and overseas that support the RHS by offering free entry to members at selected times of the year.”

For UK gardening tourists, the choice is clear: get an RHS membership to unlock free access to all five flagship gardens and hundreds of partner gardens. For those visiting Ireland, invest in RHSI membership too — or risk paying entry fees at Irish partner gardens. The trade-off is simple: £49.50 a year buys you a season of garden hopping, while going without means planning around individual ticket prices.
