July Highlights

Visitors Center

Aesculus californica – California Chestnut

This tall growing shrub is showing its true colors right now! Blooming white, this shrub’s flowers are grouped together to form the shape of a very large cone, and these cones cover the entire outer portion of the plant. Stop by and look for yourself today!

Hawthorn Trail 

Acer Palmatum ‘Ornatum’ – Red Laceleaf Japanese Maple 

This is a beautiful Japanese maple specimen! Growing to about 10-15 feet in height and width, it features lacey star-shape leaves, with lobes that are thin and serrated. With a variable shaped habit, and red fall color, it makes for a great addition to a home landscape! 

Magnolia Trail

Holodiscus discolor - Ocean-Spray

Ocean Spray is beautiful in July! This fast-growing shrub has cascading clusters of white flowers that have a fluffy-looking appearance. The flowers also have a faint sweet, sugary scent, so don’t forget to stop and take a second to smell Ocean Spray!

Pine Trail

Araucaria araucana - Monkey Puzzle Tree

The Monkey Puzzle Tree is a tree that can be enjoyed all year! This conifer is Native to Chile and has quite the puzzling appearance! It has evenly spaced tiered branches, and the “leaves” are triangular, leathery and pointed at the ends. These “leaves” also cover most of the trunk. Just be careful when observing, as this tree is very sharp!

What's in Bloom?


Magnolia wilsonii

This Magnolia is native to China where it grows as a forest understory plant.  This is an unusual magnolia, in that the blooms are pendulous, meaning downward-hanging.  Their crisp white blooms are beautiful with bright maroon stamens in the center. 

This magnolia can be found at the western confluence of the Taylor and Magnolia trails in the Magnolia Collection.  Take a look today!
