TRIUNFO CREEK PARK MARCH 2017
PAGE ONE




Triunfo Creek Park is a lovely 600-acre expanse of oak woodland, grasslands and massed displays of goldfields and other wildflowers adjacent to the community of Westlake Village. The entrance is near the intersection of Lindero Canyon Road and Triunfo Canyon Road. The main trail that most people use is called the Pentachaeta Trail, named for the Pentachaeta lyonii which blooms profusely in April and May, but there are many other less-travelled and sometimes almost indistinct trails across the higher reaches of the park, and it is along some of these trails that several very rare plants may be found, such as the first one below. I visited recently with NPS employee Tarja Sagar, Resident Botanist for the Santa Monica Mountains National Recreation Area, and returned a few days later to walk the Pentachaeta Trail. The picture above is of Allium haematochiton or red-skinned onion. An asterisk next to the common name is for a non-native taxon, and an upside-down V is for a species that was new to me.
