Early Spring Flowering Plants

 I look out my window and see deep pink ruffled flowers covering my Blireiana flowering plum.   It's one of my favorite early spring blooming plants and those fragrant blossoms are strong enough to scent my garden. It grows next to an Autumnalis flowering cherry that blooms nearly every month of the year. I'm not kidding. It's the energizer bunny of the flowering tree world.  We all look forward to the earliest flowers of the new season.  What else blooms in winter that you might want to have in your garden? Here are just a few suggestions.

One old fashioned shrub that figured prominently in many old gardens is forsythia. Deep golden-yellow flowers completely cover the bare stems in late winter and become the focal point of the landscape when in full bloom. The showy stems of this easy care shrub are great for cutting. Forsythias are native to eastern Asia but a chance discovery in Germany by a grower who specialized in breeding for the cut flower industry led to the especially vivid variety Kolgold in the 1800's. Forsythia has long been used in Chinese medicine. The flower petals contain powerful bacteria-fighting properties which make it an important dressing.

Hellebores are another winter blooming plant that with foliage that looks great, too. My double purple one has been blooming for well over a month now. I've got my eye on a variety called Golden Sunrise. Each plant is  different with variations of large, canary yellow flowers. Some are solid yellow but most have some degree of red veining and a red picotee edge. Some have a red starburst in the center. Hellebores bloom for six weeks or more and are deer and rabbit resistant. They are often flowering during the Christian season of Lent from which they get their common name, Lenten Rose. Use them for naturalizing in woodland areas. They are a low maintenance plant, will survive with little water and are disease and pest free.

What would a shade garden be without a bright orange clivia? Every year I look forward to their huge flower clusters to emerge from the dark green strappy leaves. Even in dark shade they will bloom and brighten the winter garden although they would do fine in morning sun. If you have a north facing window you can grow them as houseplants. Clivias are hardy to several degrees below freezing but mine, under an overhang, have survived temps of 23 degrees without damage.

Clivia breeders have produced gold and peach colored flowers also but I still like the standard orange and they didn't cost $599 like the plants I saw offered on the internet. I thought this price might have been a misprint but on further investigation I found another site offering the yellow Gloria clivia for a mere $950. I'll stick with my orange ones.

A beautiful vine that blooms in winter is Hardenbergia 'Happy Wanderer'. In the pea family, this evergreen vine looks like a small wisteria when in bloom.  Pinkish purple flowers cascade in clusters on twining stems that reach 12-16 feet long. It requires little water once established and is hardy to about 23 degrees. If you have an older, tangled plant you can rejuvenate it with hard pruning in early spring after flowering. Never prune in late summer or fall because you will cut off the wood that is going to bloom the following winter.

The last plant I couldn't live without is Fragrant Sarcococca.   The tiny flowers of this plant are easily overlooked but you can't miss their scent. If you have a problem spot in dry, deep shade give this plant a try. It's easy to grow, deer resistant and trouble free.

Fragrant Roses & How to Prune Them

I'm daydreaming about the flowers of spring and summer and what could be more impressive than a big, fragrant, jewel-toned rose? There are some great new ones out this year that I have my eye on. Maybe you have room for one more.

Fragrance is a requirement for me when it comes to roses. First thing when we admire a beautiful rose is to bend over and smell it. Sure vase life and petal count are important but who can resist a fragrant rose? With that in mind, several of the new varieties out this year fit my bill. Consider one of these for your garden.

Orchid Romance is a small, medium pink to lavender floribunda rose. It has a strong citrus aroma on warm days. Grown on its own root it has good disease resistance and holds up well in a bouquet. Medium large, very full flower clusters bloom in flushes throughout the season.

Sugar Moon is an elegant pure white rose with huge, full, classically formed buds. Saturated with an intensely sweet citrus and rose fragrance the scent is said to nearly bowl you over. Long cutting stems makes this a perfect addition for the cutting garden. Superior disease resistance is another plus for this new rose.

Cold weather earlier this month has kept roses in the garden dormant but now is the time to prune them before they start leafing out which wastes plant energy. I want them to produce lots of roses on a compact shrub not just a few exhibition size so I prune shrubs moderately.  Heirlooms, however, require less pruning because their open look is part of their charm.  Remember your goal is to keep the center of the plant open for good air circulation.  Aim for a vase-shaped bush with an open center by cutting out crossing canes, spindly, weak, broken or diseased stems as well as dead wood. Cut back the remaining stems by about one-third, cutting canes at a 45-degree angle, just above an outward facing bud.

Don't worry whether you're pruning job is perfect. Roses are super forgiving and you can trim them up again later. I once helped prune the rose garden at historic Gamble Gardens in Palo Alto. To revitalize the old shrubs we sawed out most of the beefy canes. I didn't think they could recover in time for the big May bloom but they did and were spectacular. Roses are like redwoods -you can't kill one- they're the energizer bunnies of the plant world.

Climbing roses require little pruning. Cut out extra stems if there are too many and also cut back long established canes to where they are slightly thicker than a pencil. Then cut each side stem down to several inches. This will cause the cane to flower along its complete length for a beautiful spring display.

Remove any leaves that may still be clinging to the bush. Rake up debris beneath the plant and discard to eliminate overwintering fungus spores. It's a good idea to spray the bare plant and the surrounding soil with a combination organic horticultural oil to smother overwintering insect eggs and a dormant spray like lime-sulfur to kill fungus spores. If you usually only have problems with black spot you can use a mixture of 1 teaspoon baking soda with a few drops of light oil in 1 quart water and spraying every 7 to 10 days.

And that's all there is to it. Email me if you have any questions.
 

A Private Arboretum in the Santa Cruz Mountains

Recently I had the honor to tour a remarkable garden in Scotts Valley. This horticulturalist calls himself a hillbilly gardener but he is no such thing. Some of his plants come from as far away as Oklahoma, Texas and Hawaii. What a thrill to see spring growth emerge from the new leaves of his unusual trees, flowering shrubs and perennials.

Our first stop was to admire his large collection of echium candicans or Pride of Madeira. These stately shrubs reach 5-6 ft tall and 6-10 ft wide so they make quite a show when the huge flower clusters are in full bloom. Being deer resistant and drought tolerant they are perfect for our mountain environment. The color of the spikes varied from pink to lilac, sapphire blue and purple. This gardener is resourceful. He got many of his seedlings along Hwy 17 where they had reseeded after being used as brush to stabilize the slopes after the ’89 earthquake. The bees were really happy visiting the hundreds of blossoms on the beautiful spring day that I was there.

Tucked under wild cherry trees collected in Texas, are second generation iris of dark purple and pure yellow. Originally from his grandmother’s garden in Virginia, these iris are descendants from a light blue variety and a pale yellowish-beige douglas iris.

This extraordinary gardener also has a huge wild rose from Missouri covered now with fragrant white flowers, a wild olive from Texas and a sand plum from Oklahoma.  There is a yucca about 4 ft tall that he and his brother started as cuttings when they were teenagers in Port Arthur, Texas. He is also the proud father of a couple of bald cypress complete with "knees". This tree of southern swamps and other low nutrient areas grows woody projections above the ground or water level to act as a structural support and stabilizer allowing them to resist very strong winds. Even hurricanes rarely overturn them.

A beautiful Canary Island palm, planted from a seedling in 1996 that he had nurtured in a gallon can, is now over 9 ft tall.  Akebia vines grow up oak trees, passiflora and white wisteria vines up redwoods, a yellow banksia rose rambles up into a madrone and madevillea laxa is happy growing up an oak, too. A willow-leafed hakea salicifolia, indigenous to New South Wales and Queensland, graces his entry with its tiny, white fragrant flowers.

Other trees this gardener loves include Causarina, native also to Australia, sugar pine, incense cedar, Western red cedar, deodar cedar, staghorn sumac and a maytens tree.  His mother in Pennsylvania taught him to plant his first garden at age 4 and he cherishes his Eastern white pines, pinus stroblis, and giant sequoias, three of which he grew from seed.

And I can’t forget his collection of salvias. The red flowers spike of salvia confertiflora bloom year round. The beautiful salvia mexicana will soon to be covered with rich, blue flowers. He also grows salvia chiapensis and a salvia-like plant native to Hawaii called salvia lepechinia. This deliciously scented plant will be covered soon with reddish lavender lipstick-like flowers adored by hummingbirds like all the salvias.

A new greenhouse where he has a small collection of orchids will soon house new seedlings that are sprouting in a germination station under lights. Of the many Hawaiian seeds he has collected are maile, a flowering plant that is probably the oldest and most popular material used in leis by early Hawaiians, milo- a chocolate and malt powder popular in many parts of the world, gossypium tomentosum, coral vines, hibiscus and the koa tree.

There were hundreds more cool plants I learned about and got to admire that day. I’ll be visiting this garden again and again for the next round of wonders. it’s a marvel.
