Fall Wildflowers & October to-do’s

Above the clear turquoise water of the Big Sur coastline, wildflowers still bloom in October. Bright orange Sticky Monkeyflower meander among a carpet of rosy blooming California Buckwheat. Deep orange California fuchsia flower on hillsides alongside the bright white flower heads of yarrow. They make a striking combination. Under the partial shade of pine trees lavender Seaside Daisy explode with color. Even poison oak contributes deep rusty-red tones to the landscape making it easier to identify and avoid. This wild land offers lessons and ideas to make our own gardens more beautiful.

Big Sur has areas of chaparral, oak and pine woodlands, riparian or streamside woodlands and redwood-tanbark-oak woodlands. Nearly half of all the flora of California grows here and many northern and southern California plants mix in this unique location. . Only in Big Sur will redwoods and yuccas thrive together. The look is startling. Certainly not a combination you would think of for your own garden.

Near McWay Falls on Hwy 1, fragments of an elaborate stone house still remain along with some of the landscaping. Christopher McWay and his wife Rachel settled the area in the late 19th century.The land passed through several owners until former U.S. House of Representative Lathrop Brown and his wife Helen acquired it and built a beautiful stone structure overlooking McWay Cove. The house was torn down 50 years ago but many of the landscape plants still thrive after all these years.  Hardy pittosporum eugenoides have survived without any supplemental watering. A huge stand of blooming Naked Ladies covers the rocky slope. We all know what survivors these bulbs are. Tall Mexican palms and ornamental trees surround the fragments of stone staircases and walls reminding us that nature will endure.

What allows all plants to thrive in their environment is the simple set of conditions that they like. It's nearly impossible to grow ferns in the hot sun around here and don't even think about trying a California fuchsia in the shade. Soil is important, too. Rich, moist soil is perfect for wild ginger but gravelly, well drained soil works best for Five-fingered ferns. Match the right plant with the right spot and you'll have success every time. Big Sur is a chock full of success stories.

Here are more tips for early fall in the garden.

Fall is not a good time for major pruning.  Wounds heal slowly, leaving them more susceptible to disease.  As a general rule, don't prune when leaves are falling or forming.  Wait to prune most trees until late in the dormant season or in late spring after leaves and needles form.  To avoid sap flow on birches and maples, prune after leaves mature.  

Do refresh perennials, such as butterfly bush, salvia and yarrow by cutting a third to half of their growth.

Rake leaves– compost or put in your green can. If large leaves are left in place they will mat down and set up fungal problems come spring.
 

Fall Blooming Perennials

Every garden changes over time.  Gardening is a process, a constant experiment so don't get discouraged when things don't go exactly as planned. For example, a cool spring may cause some things to bloom later while a warm, dry winter speeds up plant and flower development. Maybe that pink flowering tree now conflicts with the red blooms nearby. Whether it's caused by climate change or just the weather, take comfort that your garden can grow more beautiful each year with a little tinkering now and then.

At this time of year look to the following plants combined with ornamental grasses coming into bloom to carry your garden until autumn color from trees and shrubs kicks in. Go for dramatic extravagance with color combinations than inspire.

Russian sage.  Tall, airy, spike-like clusters , create a lavender-blue cloud of color above the finely textured gray leaves. This perennial has a long blooming season and the cool color of the flowers is stunning in the fall garden. There are several varieties available with different shades of soft blue to violet blue flowers. Most grow 3-4 ft tall. Little Spire Russian sage is a shorter, upright selection that doesn't flop over in the landscape. It adds a sense of lightness to the garden. You'll love the cool color on a hot day.

Aster x frikartii 'Moench'.  The lavender-blue flowers on this perennial can get 3" across and cover the plant with blooms from early summer to fall, even longer in mild winter areas if spent flowers are removed. They attract butterflies and make a good cut flower. This reliable, drought tolerant plant thrives in full sun, grows 2- 3 ft tall and is mildew resistant.

Agastache which is also called hyssop attracts hummingbirds, butterflies and bees to your garden It's also deer resistant. Aromatic foliage on Blue Fortune smells like peppermint-lemon when brushed or crushed. The flowers on Electra are vivid orange. Then there's licorice mint hyssop, orange hummingbird mint hyssop, anise hyssop and a whole slew of hybrids of every color in the rainbow- lavender, pink, apricot, orange, purplish, coral, powder blue, tangerine, red – you name it. Agastache is easy to grow in full sun or partial shade and is drought tolerant. Just be sure to provide excellent drainage.

Salvia-  the workhorses of the garden. Their long blooming season makes them right at home in the fall garden. There are some 900 species of salvias.  They are the largest genus in the mint family. Choose from many new cultivars like Dancing Dolls with rose and cream colored flowers. Another good choice is a Ca. native hybrid called Starlight that blooms with long white flower wands that really stand out at twilight.
There are lots of Salvia greggii varieties available such as Pink Frills, Golden Girl and Neon Dancer which has vivid rose and red flowers.  Salvias are drought tolerant and deer resistant (really). Although they tolerate some shade they looks best when planted in full sun. To encourage repeat bloom trim off spent flowers stalks when they start to look rangy. They will rebloom for months.

Another common plant from this huge family is the Mexican bush sage.  So showy that people mistake them for huge lavender plants. They are vigorous and upright growing to 3-4 feet tall and as wide.  Velvety purple and white flowers cloak foot-long stems. Salvia Santa Barbara is a compact selection that grows 2-3 ft high and spreads 5 ft wide. They stop blooming only when frost hits them.  To limit plant size and renew flowering stems, cut back close to the ground before spring growth begins.  You can't go wrong with these plants if you have a large space to fill.  Hummingbirds love them, too.

Perennials should be planted in multiples, not only for beauty's sake but also for lower maintenance. Let your trees and shrubs lend structure and year round interest with an explosion of perennial color that gets all the attention. Just don't hesitate to change what needs adjustment or transplanting if needed to a better location.
