The Woodland Collections contain a wide variety of plants native to the many and varied woodland communities of the world.

The Deciduous Woodland

This area is home to many species of trees and shrubs that lose their leaves when the weather cools in autumn, then leaf out again in the warmth of spring. The annual cycle of spring and summer growth alternating with winter dormancy is characteristic of these species. Deciduous woodlands are commonly found in eastern North America, western and central Europe, and eastern Asia. Our collection includes species from all over the world, many of which have leaves and flowers that display vivid colors in the fall, spring and summer months. A diverse collection of both perennials and bulb species that are adapted to deciduous communities create a colorful understory within this woodland.

ConifersThe Conifer Collection

The Conifer Collection contains coniferous (“cone-bearing”) species from around the world. These forests primarily exist in the Northern Hemisphere, however Araucaria is a unique genus of conifers native to the Southern Hemisphere. This collection contains specimens of these as well as a number of pine, cedar, juniper and cypress species. The climatic distribution of conifers is extremely diverse and can include tropical, temperate, arid, and extremely cold and harsh environments. Most of the species are evergreen, and many are characterized by needle-like leaves.

The Ficus Grove

Ficus or “Fig” trees are found in the warmer climates of the world. They are often associated with the tropics and tropical rainforests, however some species can survive in more arid habitats. Ficus trees are well—known for their tasty fruit, however only a few species produce figs that are edible. This collection contains a number of species from different regions of the world, including the celebrated Bo tree (Ficus religiosa), and Ficus benghlaensis, the species known for its extensive aerial root system.


A variety of colorful subtropical trees and shrubs live on this hill, including a small but unique collection of cycads. Subtropical species from Africa, Australia, and South America exhibit the diversity of world vegetation represented within this Arboretum. The hilltop also offers a vista of the lake and surrounding area.

GymnoconeThe Primitive Plants Garden

The plants within this section were abundant during the Jurassic period—approximately 300 million years ago. Our specimens include dawn redwoods, cycads, ginkgoes and magnolia relatives. Magnolias are considered to be one of the most primitive of true flowering plants.

TreeThe Rainforest

This collection primarily consists of subtropical specimens, with a small number of truly tropical species. True tropical “rainforest” vegetation requires a greenhouse environment to survive within Southern California’s dry climate. The trees, epiphytes, and shade-loving understory within this collection resemble the layered vegetation pattern characteristic of tropical forests. Epiphytes are plants that grow on the surface of other plants (commonly trees) for support.

The Redwood Grove

This stand of Coast Redwoods (Sequoia sempervirens) forms the southern edge of the conifer collection. These redwoods also naturally mark the southern limit of the coastal coniferous forests in California. They are the oldest and largest of the coastal tree species, and require coastal fogs to thrive. An understory of common native California species provides subtle color in this shady grove.

The Subtropical Garden

This new section is split up into a number of geographical sections representing their subtropical plants. When walking through this garden you will see plant species from Central and South America, Mexico, Asia, New Zealand and Australia, Africa and Madagascar and a selection of Island plants from Hawaii, Mauritius, Socotra, Reunion and the Canary Islands. Many of these plants grow here successfully with the addition of summer irrigation.
