Where are Plant Finder & Plant Selector?

We have combined these two powerful search tools into a single Find a Plant service searching over 250,000 plant records.

Virtually all of the features of the old searches are still available and in addition we have added several new features to create a more comprehensive and user friendly search experience.

When using this search

  • If you enter just a plant name, you will see results from the old RHS Plant Finder and Selector databases
  • If you select any attributes with or without a plant name, you will see a much narrower selection of results taken only from the old RHS Plant Selector database. These plants will have a lot more details displayed including an image.
  • Our Botanical team are working hard to increase the number of plants with detailed information.

Search by plant name, key attributes or both to find plant details and a list of suppliers.

 
  • AGM plants

    AGM plants have been through a rigorous trial and assessment programme. They are:

    • Excellent for ordinary use in appropriate conditions
    • Available to buy
    • Of good constitution
    • Essentially stable in form & colour
    • Reasonably resistant to pests & diseases

RHS Plant Trials

We trial a wide range of plants to test their health, performance and weather endurance. The best performers could receive a prestigious RHS Award of Garden Merit

Zantedeschia 'Captain Lovely'

RHS Plant Trials provide the opportunity for multiple varieties of the same plant to be grown together, side-by-side, so they can be compared. They are assessed by an expert RHS forum panel who use the trial results to inform their decision to grant plants the RHS Award of Garden Merit (AGM) status - our seal of approval that the plant performs reliably in the garden. 
 

What kinds of plants do we trial?

We trial both commonly-grown existing cultivars and species of plants, and brand new introductions. This helps gardeners pick the best plants for them by giving the most up-to-date information. The plants are normally grown from seed and vegetative material submitted by nurseries, individuals and breeders.
 

Where are the plants trialled?

Visitors to RHS Garden Wisley are welcome to view current trials on the Trials Field. Off-site trials are also held at gardens and nurseries across the UK - many of which have special public open days.
 

How are the trials assessed?

Each trial is assessed by a specialist forum, made up of experts in that particular group of plants. Their findings are then ratified by a Plant Committee.

See our list of current plant trials which includes many ornamental and edible crops.

You can download Plant Trials Reports and see details of current and past trials from the RHS Trials Database.

We also produce Grower guides which contain more information and interpretation to help gardeners make the most of the results of our trials.

RHS Herbarium

Trials are an important source of material for the RHS Herbarium located at Wisley, which comprises many separate collections. The primary focus of the collections is to maintain and to acquire reference material of plants in cultivation.
