Plant Collections
The plant collection is organised by the Cronquist classification system (1988). This means the garden can be used as a teaching resource for botany students as well as a recreational space for the wider community.

As an indication of the relative sizes of the subclasses, Reveal gives the following numbers:
| Subclass | Orders | Families | Species |
