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.
