The Importance of Fall Planting and What to Plant Now.

15 Sep

As summer blooms start to wind down and the days gradually get shorter, many gardeners tend to step back from their gardens. But actually fall is one of the very best times to be active and planting in the garden. Perennials, be they shrubs or smaller plants, need a bit of time to get their roots firmly established before they fashion a new growth spurt. Getting shrubs, other perennials and early blooming CA native annuals started in the fall offers several advantages. Most importantly, the cooler weather and winter rains provide the perfect conditions for them to get established. Not only will that lead to more successful blooming in the spring or summer but it will often mean that they will bloom earlier than if planted in early spring.

Planting shrubs or other larger perennials in the fall also helps you with your garden layout. Once these ‘foundation’ plants are situated, it is easier, come spring, to plant smaller perennials or annuals in coordination with these shrubs. Fall is also an excellent time to add bark mulch to your planting beds, be that to established plots or to newly planted beds. This mulch will limit the growth of weeds, help to retain moisture and for frost tender shrubs, help to insulate the roots. We can roughly divide fall flower planting into 5 categories – shrubs for sun; shrubs for shade; grasses; ground covers and vines. I’ll give examples of each below.

Shrubs for Sun

There are a great many sun-loving shrubs that benefit from being planted in the fall. Buddlejas are one of my favorites. Known as butterfly bushes, they produce 10-14” long cones densely packed with tiny nectar-rich flowers. You can find four fabulous varieties at Annie’s. These include the compact ‘Ellen’s Blue’ and ‘Hot Raspberry’. These 3-4 high and wide shrubs attract an endless parade of bees, butterflies and hummingbirds, with the former displaying purplish-violet flowers and the latter showcasing vivid magenta blooms.

Davidii ‘White Profusion’ is a full-size bush, 6-8′ H & W. The flowers are a pure white, making this plant a perfect addition to a Moon (white) Garden.

Three other shrubs benefit from being planted in the fall. California lilac (Ceanothus) can be a bit slow to establish so starting this California native evergreen in the fall has its benefits. You’ll find nearly a dozen varieties at Annie’s, with flower colors ranging from the palest lavender (‘Gloire de Versailles’) all the way to vivid purples (Ceanothus ‘Julia Phelps’ or ‘Dark Star’). At home in sun or light shade, these Ceanothus are great foundation shrubs.

If pretty foliage is your goal, Chinese Fringe Flower (Loropetalum chinense ‘Plum Delight’) is a great way to add rich burgundy tones to your garden. Reaching 4′ high and spreading to 7′ wide, this durable evergreen produces unique, pink finger-like flowers in the late spring.

If on the other hand it’s flowers, and in particular exceptionally pretty blue flowers, are your thing, Blue Glory Bower (Clerodendrum ugandense) may be just the ticket for adding something unique to your garden. Sporting the palest blue butterfly-shaped flowers, each with a central vivid blue petal, this African native is quick to establish and equally fast to bloom. Easily reaching 7′ tall, with arching branches, it is a standout in any garden.

You can plant it as decorative meadow grass or use it next to a pond, since it likes some moisture. Where this Carex’s color is subtle, Orange New Zealand Sedge displays vivid coppery-orange foliage in the colder winter months. That color is best seen when this 2′ high grass is planted in sun but even in some shade, it is a great way to add contrasting foliage color to the greens and creams around it.

Shrubs for Shade

Two colorful shrubs for shade lead this group. We have available two species of Angel’s Trumpet (Brugmansia) – the slender golden trumpets of B. sanguinea ‘Inca Princess’ and the fatter, more classic bells of the white blooming B. ‘Wedding Bells.’ The latter’s blooms are an amazing 7” in diameter, with glossy yellow ribs. ‘Inca Priness’ loads up with 7” long cheerful golden blooms and when in full bloom, puts on a dazzling show.

Meanwhile, two white-blooming Hydrangeas offer part sun delights. H. arborescens ‘Annabelle’ produces huge heads (8-12” across!) of pure white flowers in spring. 4’x4′ mature plants are so prolific, you barely see the green foliage.

Dwarf Oakleaf Hydrangea (H. quercifolia ‘Pee Wee’) gets to a similar size, with panicles of alabaster white flowers, offset by highly attractive, oak-shaped mint green leaves. Even when not in bloom, this hydrangea is a standout for a shady to part sun location.

Two outstanding shrubs for shade offer enticing scents. Heliotropium arborescens and H. arborescens ‘Alba’ each produce clusters of heady, vanilla-scented flowers, the former with purple and white flowers and the latter with all white flowers. Smaller shrubs, they each top out at 3’x3′.

Meanwhile, Mock Orange (Philadelphus ‘Belle Etoile’) offers clusters of pure white flowers that smell intoxicatingly of ripe oranges!

Grasses

Fall is an excellent time to start ornamental grasses. Pink Muhly grass sounds like an odd common name but Muhlenbergia capillaris is one the showiest grasses you will ever grow.

Its calling card is its vivid pink seedheads, which completely smother the plant in late summer. Forming an upright 3’x3′ mound of narrow, brownish-green leaves before its flowering, this drought tolerant, durable grass is also a valuable source of seed for local songbirds.

Two other Muhlies are worth exploring – the southwest native M. dubia and M. reverchonii ‘Undaunted.’ The latter features reddish-mauve seedheads and is likewise cold hardy, very drought tolerant and long-lived.

And how about growing the state grass of California?! That would be Purple Needlegrass (Stipa pulchra). Widespread, it forms 18” high clumps whose seedheads start out purple then age to a silvery color. Nodding Needle grass (Stipa cernua) is another durable native that reaches 2′ tall and produces unique ‘bending’ seedheads.

For great foliage color, there’s no beating New Zealand Wind Grass (Stipa arundinacea). Much sought after by west coast gardeners for its golden-ginger blades, it reaches 3-4′ in height. It looks fabulous when massed and equally showy when featured in a container. A real statement plant!

Vines

Vines occupy a particular place in a fall planting scheme as many actually bloom in the autumn. That shouldn’t preclude you from planting them now and one of my favorites is Passion Flower vine (Passiflora). Whether it is an edible type (P. edulis “Frederick’) or one of many ornamentals, this vine produces some of the most unique and colorful flowers in the floral kingdom.

Annie’s selections divide themselves roughly into two groups – those with pronounced filaments (P. actinia, P. ‘Blue Horizon’ and P. loefgrenii x caerulea) and those whose parentage includes P. manicata (‘Susan Brigham’ and ‘Oaklandii’) or P. parritae (‘Cocktail Orange’ andMission Dolores’).The latter passifloras showcase large orange, coral or red flowers, with few or no filaments. Whichever you choose, the flowers are bold, eye-catching and known to attract butterflies.

Several other vines offer their own treats, be that the fragrant flowers of Pink Jasmine (Jasminum polyanthum ‘Pepita’), the vivid purple flowers of Clematis ‘Polish Spirit’ or the blazing red fall foliage of Roger’s Red grape (Vitis californica x vinifera ‘Roger’s Red).

Ground Covers

While ground covers are often overlooked when it comes to fall planting, they too can benefit from a head start. African daisies (Osteospermum) are a great example, getting a head start on spring blooming when planted in the fall. We have 3 colorful varieties, ‘3D Double Purple’, ‘Compact White’ and ‘Zion Copper Amethyst.’ The 3D Double Purple is noteworthy for its flowers not closing at night, as is the case with most Osteos.

Our California native Blue-eyed grass (Sisyrinchium) particularly benefits from a fall planting, leading to not only an earlier flowering but a more robust one as well. S. hybrid ‘Devon Skies’ not only flaunts the bluest flowers but some of the largest ones in the genus. S. bellum ‘North Coast’ has slightly smaller and more purple blooms while S. californicum offers cheerful yellow flowers.

Lastly, the curiously named Golden Pennywort (Lysimachia nummularia ‘Aurea’) is a fabulous ground cover that can either spread out on level ground or cascade over a low wall. It benefits from a bit of shade and even though it loses a few leaves in winter, it fills out a gloriously gold come spring.

To Conclude

“The beauty of planting shrubs and other perennials in the fall is that you are rewarded with its benefits no matter what climate you live in, which particular plants you add or the plants being of a large size or small. So, time to get out that shovel and get going!”

Availability

Just so everyone knows, some of the Annie’s Annuals plants mentioned here might not be available on the week that you’re reading this blog article. Some of the plant varieties discussed are only available in our retail nursery in Richmond CA. This is generally due to us only being able to grow small crops or the fact that the particular plant does not ship well. A quick look at that plant’s page will let you know if it’s available. If not, just click the Add to Wishlist button and we’ll notify you when that plant is ready to take home.

We’re Crazy for Clematis

12 Sep

No shrinking violets, Clematis are some of the most beautiful, hardy and heart-stoppingly gorgeous perennial vines in the world. Boasting a wide range of flower colors and shapes, they come in 10 different forms – everything from the large, four-petaled montana hybrids and showy large-flowered peony-type double forms, to those with narrower saucer or star-shaped petals and delicate nodding tubular flowers. Throw in colors that range from pure white to shades of pink, red and purple – even yellow – and you get an idea of how there can be over 250 species or varieties found nearly worldwide.

Many of us enthusiastic gardeners tend to think of Clematis as Spring blooming plants and indeed, there are many varieties that do bloom in Spring. But some species and their hybrids bloom as early as March and as late as December in mild climates, giving us Bay Area gardeners plenty of choices for our trellises, arbors and fences. The wide-ranging bloom times are also a boon to our fine feathered and winged friends, as Clematis make an excellent nectar-source for hummingbirds and all manner of bees and other pollinators.

Now is an especially good time to get Spring blooming varieties in the ground, giving their roots a head start and resulting in a more robust plant come April. If you plant Fall blooming Clematis now, you’ll be giving them nearly a full year to establish, virtually guaranteeing an excellent bloom show next Autumn.

Fall Bloomers

With extravagant wine-red flowers, Clematis ‘Madame Julia Correvon’ blooms over a long period in Summer and Fall, with large (3”) single flowers. This heirloom selection boasts quite possibly the richest red flowers of any Clematis, putting on a spectacular show in Fall. Reaching 8’ tall and 5’ wide, the fast-growing, lacy foliage looks especially nice twining up a trellis or scrambling over a fence. This beauty performs wonderfully in warm Winter areas where many large-flowered varieties refuse to grow. A pruning Group 3 variety, it blooms on new growth, so prune to about 1’ tall in early Spring for a bigger and better display every year! 

Speaking of show stoppers, Clematis texensis ‘Duchess of Albany’ offers up the loveliest pink flowers from mid-Summer to early frost. Featuring equally large (3”) five-petaled flowers that are cotton candy pink with deeper rose-pink ribs, this hardy selection dazzles in the Fall. Adding to its charm, flowers have tapered petals, giving the impression of five hearts bound together. An heirloom from 1890, this selection reaches a modest 10-12′ in height, making it perfect for a trellis or arch. No worries this climber will take over an area! Another bonus is that this Clematis can take more sun than many varieties. 

For those “Prince-ly” lovers of purple, there’s nothing more beautiful than the velvety purple tones of Clematis ‘Polish Spirit’. This C. viticella hybrid is a later blooming variety with saucer-shaped, luminescent violet-purple petals. During Summer and early Fall these large (3-4”) blooms nearly smother the mid-green leaves, making for a spectacular show. It fills out to a nice compact 10′ x 10′ size, usually in one season and year by year it adds more flowers, especially if it’s pruned to 1-2′ in Winter. This variety is ideally suited to mild climates, where some other species may not thrive. It’s also disease resistant and one of the easiest Clematis to grow.

Blessed with a deliciously heady vanilla fragrance, the aptly named “Sweet Autumn Clematis” (C. paniculata) bursts into a cascade of starry creamy-white 1” blooms in late Summer, practically smothering the foliage thru Fall and prompting curious friends to ask “Wow, what is that?” The cornucopia of flowers are followed by silky seedheads, prolonging its appeal. Vigorous and tough as nails, it can reach 20′ by its second year. Kept in a pot, it may top out at 8-10′. This herbaceous Clematis is perfect for covering an unsightly fence, trained up the side of a house or even climbing up into a tree. You’ll want to prune it hard, back to 1′ in late Winter, so any Fall foliage obscuring taller plants will be removed. You can even prune it mid-season before the flowers arrive to keep it smaller.

Spring & Summer bloomers

Some Clematis like to get a head start on the year and that’s particularly true with eye-catching Clematis armandii ‘Apple Blossom’. This selection carries the distinction of being one of the few evergreen species in this genus, with large leathery leaves that can reach a foot long and 4” wide. Leaves begin soft and bronze on color before maturing to a deep green. Climbing quickly via twining tendrils, this sweetly fragrant bloomer can shoot up almost overnight in Spring. Volumes of rose-colored buds soon open to pink-blushed 2” white flowers, attracting a vast contingent of bees and hummers. Given its rapid growth to 15′, its dramatic floral show and sweet vanilla fragrance, this is the perfect candidate for growing along a walkway, be it over an arch or up the side of the house. No problem pruning this vine to shape; it simply grows back right away!

Charm-incarnate is one way to describe the lovely and easy-going Clematis macropetala ‘Blue Bird’. Lime-green foliage in Spring soon gives way to an abundance of nodding periwinkle-blue flowers over a long period in late Spring and Summer. These open 3” bell-shaped flowers feature contrasting cream-colored stamens, making it a one-of-a-kind beauty. Its delicate semi-double flowers belie its toughness, as ‘Blue Bird’ isn’t fazed by extreme heat, cold, humidity or seaside conditions. Once the flowers are done, large silky seedheads (great in dried arrangements!) prolong the plant’s attractiveness. Though it can take a lot of sun, this species also tolerates shade. Throw in the fact it blooms on old wood (no pruning necessary) and stays a modest 12’ tall and you pretty much have the perfect vine.

Don’t let the funny name stop you – Clematis ‘Rooguchi’ is one of the longest blooming varieties, pumping out cute nodding purple bells from late Spring well into Fall. What the flowers lack in size (1.5”), this vigorous climber makes up for in volume. Each flared bell has a stiff, almost, waxy feel and the flowers are presented facing outward, adding to its charm. Though it possesses no tendrils, once you start it on a trellis or netting, it’s off and running. One plant can easily cover a 15′ x 15′ area in record time. Prune to the ground in late Winter and keep an eye out for new stems emerging in the early Spring.

Growing Clematis

All Clematis are cold hardy, with all of the above selections classified as USDA zones 4-10, with the exception of C. armandii, which is still a champ in USDA zones 6-10. In cooler climates you can plant these Clematis in nearly full sun or, if appropriate, part sun. In hotter areas, they’ll prosper best in morning sun and afternoon shade. The two exceptions are the sun-loving Clematis ‘Blue Bird’ and C. armandii ‘Apple Blossom’. Whether planted in the ground or in a large container, it’s advisable to cover the top of the soil with bark mulch to keep the roots cool. Choose a quality soil amendment to both add nutrition and to ensure good drainage. Root rot is an occasional issue with Clematis, so drainage is vital. Follow pruning guidelines as listed for the particular variety you’re growing and top dress with a nutritional compost in late Winter.
