Wildflowers of Pinnacles

Goldfields surround California Buckwheat with Machete Ridge in the distance

On the first day of Spring, my wife and I set out in search of wildflowers and adventure. We found both at Pinnacles, the newest National Park (2013), just 100 miles from our house.

The adventure came in the form of some unexpected spelunking at Balconies Cave, located along the Balconies Cave trail. Thanks to recent rains, the entrance to the cave was a stream. Fortunately, we were both wearing somewhat waterproof shoes.

The cave required a headlamp and some courage, as it was pitch black and filled with slick water-soaked rocks. Unfortunately, I had no headlamp and was carrying a large camera and Nalgene bottle; not an ideal setup for navigating a damp dark passage. Thanks to a borrowed flashlight, we managed to work our way through the short but harrowing "trail" through the cave, emerging on the other side with pulled muscles and soaked shoes and socks. It's Hell getting old!

The remainder of Balconies Cave trail was a pleasant stroll through vibrant wildflower-filled meadows, cool moist canyons and along ridges adjacent to majestic rock formations. We were treated to a wonderful variety of wildflowers and beautiful blue skies.

Here is a sampling of what we saw along the trail:

On the Eve of Spring...

With the official start of Spring around the corner, I thought I'd share some scenes from around the garden. Thanks to the recent rains, foliage is looking lush and flowers are popping up everywhere. 

Heuchera, or Coral Bells, are among my favorite natives because the long-lasting flowers are among the first to appear in late Winter and come in colors ranging from cream to dark pink. They look incredible when planted in mass in a shady spot and are amenable to transplant and dry conditions.

Inspired by walks along the Gray Whale Cove trail in Montara, I planted a collection of yarrow, beach strawberry and checkerbloom underneath our ancient lemon tree. Dale the snail approves.

One of the most reliable year-round bloomers is the Island Bush Poppy, a crowd favorite that thrills with its large yellow flowers and attractive large grey-green leaves. Rains will knock the flowers down but they always bounce back with a couple days of sunshine.

Another plant that people often ask about is the Cliff-maid or broad-leaf Lewisia. These diminutive guys come in a variety of colors and bloom for a couple months starting in late February. They need good drainage and native plant books recommend using as a container plant. I have a couple planted into the rock wall and they seem happy, except in the summer heat.

Another one of my favorite natives is the California phacelia, a bee magnet that blooms early and often. Looks great in a rock garden with full sun and will appreciate some room to grow. I picked up this plant at Mission Blue nursery in Brisbane a couple months back and it is already filling in nicely.

Foothill penstemons make a great addition to a drought tolerant landscape. Their blue-purple flowers are eye catching and look great with other Spring bloomers such as monkeyflowers, poppies, sulfur buckwheat and golden aster. This particular variety, Margarita BOP, is a robust bloomer and probably the easiest to find in nurseries.

Photo of the Day: Shooting Star

Shooting Stars (Primula clevelandii) take flight
Shooting Stars are a perennial herb widely distributed throughout California in grassland, woodland, and coastal sage scrub communities. They bloom from January to April. This photo was take at the Regional Parks Botanic Garden in Berkeley in early March.

Hello, My Name is...Western Redbud

Western Redbud (Cercis occidentalis) at the Regional Parks Botanic Garden, March 2015

Hi! My name is Western Redbud, but the scientific folk call me Cercis occidentalis. I am much beloved in the native plant community because I look great year round, when properly maintained, and I'm the center of attention in early Spring when my abundant pink flowers start brightening the landscape.

Vivid clusters of flowers in early March

 I can get quite large -- 15' high and 10' wide -- and can be pruned (ouch!) to work as a small tree or a broad multi-trunked shrub. I do best in climates with hot summers and cold winters (inland), and prefer no supplemental water once established. Full or part sun will work just fine. I lose my heart-shaped leaves in the Fall, leaving my limbs bare until the blooms appear in early March.

My buddies in the yard are ceanothus, island bush poppy, and monkeyflowers to name a few (I'm pretty popular, you know). We put on quite a show when we're all blooming at the same time.

Well enough about me...

Let it Rain!

A very full bird bath with blooming bush poppy, red bud and currant in the background
According to my rain gauge, we received over 4 inches of rain in the past 5 days or so here in San Mateo. Not bad considering average rainfall for the entire month of March is only around 3 inches. The recent deluge managed to fill the bird bath, which should delight the resident crows who routinely use it to soften scavenged pieces of junk food (pizza, chicken nuggets, buffalo wings and hamburgers). Oh the joys of living downtown.

Native Plant Profile: 'Mountain Pride' Blue Witch

'Mountain Pride' Blue Witch (Solanum xanti 'Mountain Pride')
This dark-purpled selection of blue witch hails from the Santa Barbara hills. Blue witches are a common sight in chaparral and woodland environments throughout California, including here in the Bay Area at parks such as San Bruno Mountain and Edgewood.

Flowers can be blue, purple or lavender, and bloom profusely over long periods in the Spring and Summer if conditions are favorable. The leaves and round green fruits of this plant are toxic. Many native plant venders recommend planting blue witches in a container rather than in the ground. I have attempted both and agree that they are much easier to manage in a pot. My plant was purchased from Yerba Buena Nursery in Half Moon Bay last year and promptly deposited in a brown glazed pot where it is happily blooming right now.

Native Plant Profile: Montara Manzanita

Montara Manzanita (Arctostaphylos montaraensis)
I snapped this picture along the Montara Mountain North Peak trail last week. This majestic manzanita can only be found in the wild on Montara and San Bruno mountains, generally between 500 and 1500ft elevation.  It can be quite tall (up to 15ft) on protected slopes,  or very short (<2ft) on exposed granite outcrops*. Blooms are whitish/pink and held in dense clusters during the winter months.

This is one of my favorite manzanitas because (a) it's local and (b) the bright green clasping green leaves are striking to me.  I wanted to grow this shrub in my garden but it's almost impossible to find at native nurseries. A few years back my sister picked me up a one gallon plant from Central Coast Wilds in Santa Cruz. It lived in a wine barrel for a couple years, happily, and then was transplanted into the front yard this past Fall. I'm curious to see how it fares away from the coast in loamy/clay soil.
