Growing a particular group of plants can focus the expertise and resources need to support those plants, can meet the needs for research and develop, and help with interpretation and outreach.
- Garden design should plan to accomodate the for the needs of certain collections.
- Information management is needed to efficiently maintain and record the contents of collections.
Living collections can be categorised as:
- Ecological collections
Native plant collections cultivate plants from their surrounding region or national flora.
- Opening of a native plant garden, New Zealand
- Botanic Gardens - Plant conservation initiatives in the Auckland Regional Botanic Garden, New Zealand
- New plant conservation initiative at Meadowlark Botanical Gardens, U.S.A: the Potomac Valley collection
Taxonomic collections focus on taxonomic groups to support education, research, conservation and public display. For example, some gardens may specialise in the collection of ferns, others in the collection of the Palmaceae. Larger gardens may form collections of more than one taxonomic group.
Thematic collections specialise in a limited range of related or morphologically similar plants in support of education, science, conservation and public display. These include orchids, roses, Rhododendron, bamboos and succulents or thematic collections such as ethnobotanical, medicinal plants, crops (particularly minor crops in botanic gardens), bonsai, topiary, butterfly gardens, carnivorous plants and aquatics.
This approach to collection focuses on plants from one habitat or ecotype - examples of these collections include alpines, epiphytes or aquatic plants.
