Flowering Trees & Shrubs of Early Spring

Outside my window the Blireiana flowering plum is covered with dark pink, double blossoms. It’s one of my favorite early spring blooming trees with a sweet fragrance strong enough to scent the garden. We look forward to the earliest flowers of the new season knowing that winter will soon be over. Spring officially begins on March 20th.

Old fashioned shrubs like flowering quince and forsythia figure prominently in many old gardens because they are tough plants able to survive neglect and still look beautiful.

Forsythia ‘Kolgold’

The bare stems of forsythia are completely covered with deep golden-yellow flowers in late winter and early spring 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.

Flowering quince

Flowering quince is another old garden staple providing early color. They are easy to care for and nearly indestructible in almost any soil that is well drained and not overly fertile. Once established quince is a very drought tolerant plant and their spiny branches make them an excellent choice for hedges, screening or as a security barrier. There are red, pink, orange and white flowering varieties. The Toyo Nishiki cultivar even has pink, white and solid red flowers all on the same branch.

Clivia miniata

What would a shade garden be without a bright orange clivia? Every year I look forward to their huge flower clusters that emerge from between 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. Clivia 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 ones.

A beautiful vine that blooms in winter is hardenbergia ‘Happy

Hardenbergia ‘Happy Wanderer’

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 white flowers of this plant are easily overlooked but you can’t miss their scent. I have one near the front door that greets me with that vanilla fragrance every time I walk in or out. The flowers are followed by a bright red fruit. Sweet Box forms a natural espalier against a wall and if you have a problem spot in deep dry shade where other plants won?t grow give this plant a try. They are easy to grow, deer resistant and trouble free.

The Changing Season of September

You never know where new gardening ideas and inspiration can come from. The other day I stopped by to help a friend water a garden by the river in South Felton while the owners were out of town. We both enjoyed the unique combination of plants and garden art placed strategically though out the garden. It was clear that this soothing garden was created with love. If gardening keeps you sane, don?t stop because of the drought.

Covered with huge white, heavily ruffled flowers a Rose of Sharon ?Helene? anchored the entry to a small deck overlooking the San Lorenzo river. With a reddish-purple eye and handsome, leathery dark green leaves this attractive shrub will bloom nearly continuously over the summer and fall without setting seeds.

Other gems in this garden that caught my eye included a Japanese painted fern paired with a purple leaved coral bells. A foxtail fern and variegated hosta looked great nearby. Japanese forest grass, oakleaf hydrangea, liriope, helleborus and winter daphne grew among the ferns.

These are shade plants and most like a regular drink of water. They are combined with plants with similar water requirements in this garden but if your garden is in more sun remember that it doesn?t take a lot of water to make a garden beautiful. An garden_art.1920 Japanese_painted_fern-heuchera.1920unthirsty garden can fill you with joy.

Gardening makes us learn new things. If you water less frequently, some plants may decline or even die eventually. Remove those that do and replace them with plants that will thrive with less water.

Agastache ‘Apricot Sprite’

Some to try as replacements are agastache or Hummingbird mint. Plant near your organic edible garden to provide nectar for pollinators as well as hummingbirds. The flowers are edible as a salad garnish, in baked goods and in cocktails while their foliage can be added to herb salads or in a cup of tea.

Other perennials that bloom now and into fall include asters, gaillardia and all the salvias. California fuchsia are just starting their long fall bloom cycle, too.

I like the bright flowers of gloriosa daisy, especially the longer lived Goldsturm variety. These perennials make good cut flowers and are tough and easy to grow. They are descended from wild plants native to the eastern U.S. but require only moderate water once established.

Need more late summer perennials to extend your season? Coneflowers will continue to bloom until frost then go dormant for the winter. Now days there are many colors to choose from in addition to the traditional rosy purple daisies. They are lightly fragrant and make good cut flowers for bouquets. The clumps spread slowly and can be carefully divided after 3 or 4 years. If faded flowers are left in place, the bristly seed heads provide food for finches in winter.

The herb echinacea is derived from varieties of this flower. Echinacea purpurea and other varieties are used as a fortifier of the immune system, mainly to prevent flu and minor respiratory diseases by increasing the body’s production of interferon. The roots are the part of this plant used for medicinal purposes.

Echinacea was used by Native Americans more than any other plant in the plains states. It was used to treat snake and insect bites because of its antiseptic properties and to bathe burns. They chewed the plants roots to ease the pain of toothache. It was also used for purification. The leaves and the flowers can be used in teas as well.

Enjoy unthirsty color in your garden this fall.

Hydrangeas-Summer Drama for the Garden and How to Prune Them

OLYMPUS DIGITAL CAMERAThere are some plants that are so showy in the garden they are worth budgeting a little extra summer water. They really get your attention.That plant for me is the hydrangea. Want instant drama in the garden? Plant one of the many hydrangea varieties. All have flowers so large they can?t help but steal the show. Easy to grow, they are pest and disease free. Here are some of my favorites and how and when to prune them.

Back in 2001 a new variety of hydrangea macrophylla was introduced. Called Endless Summer it has the unique ability to re-bloom throughout the spring and summer on both current and older season wood resulting in a much longer blooming season. This was great news for me because as sure as the sun rises, a heat wave would descend upon my garden in May and many of my traditional mopheads and lacecaps would crisp up and the show would be over way too soon. With Endless Summer I get continuous flowering through the summer. How do I prune this variety to get the most blooms?

When you read care instructions about pruning any hydrangea and they refer to new and old wood it?s really just another name for a stem they are talking about. New stems growing this growing season will be green. Old stems that grew last year are brown.

Prune Endless Summer hydrangeas as needed to keep them symmetrical. Remove dead stems you are sure will not be leafing out this year. To revitalize a mature plant-about 5 years old- remove about a third of the oldest canes in the spring by cutting them as close as possible to the ground. If your plant looks fine, leave it alone. You can prune off spent flowers in August but I prefer to leave the flower heads on the plant for winter interest.

Classic bigleaf hydrangeas -hydrangea macrophylla- mostly bloom on last years stems or old wood. The proper time to prune them is right after blossoming in July or August. Again I like to leave the dried flower heads on for fall and winter color so I prune lightly in late summer and again now lightly to shape. I may be cutting off some potential flower buds by pruning now but those stems usually flower by early fall and I?m not wacking back the whole plant.

If your bigleaf hydrangea doesn?t bloom well any more it may be time for more drastic measures. Cut back non-blooming stems to about 6 inches high. This will stimulate the growth of news productive stems.

hydrangea_paniculata_LimelightAnother showy hydrangea with huge pyramidal flowers is called hydrangea paniculata or Pee Gee hydrangea. With chartreuse blooms, Limelight is one of my favorites. They tolerate drought better than other hydrangeas which is another plus. Because they bloom on new wood in midsummer into fall, prune them in winter or early spring. Cut away old flowers and prune to open the plant to sunlight.

Hydrangea arborescens like ?Annabelle? produce enormous white flowers and also bloom on new wood during the summer prune during the winter or spring. This is the variety you see grown as hedges. I think I need one of these in my garden.

Vying for attention in my garden is the oakleaf hydrangea or hydrangea hydrangea_quercifolia_bloomquercifolia. I love this plant because it is so versatile. I often include it in a landscape design because it is easy to grow in a variety of situations from deep shade to mostly sun and it tolerates some drought. The stunning summer display of elongated, creamy white flower clusters age to pink by autumn and then papery, rusty brown in winter. But it?s the fall display of handsome leaves that resemble oaks that will get your attention. Mine turns the color of bright burgundy but I?ve seen bronze and crimson color on others. Prune them in early summer right after flowering.

Even in our coldest winters, hydrangeas in our area are easy to grow and don?t suffer winter damage to the flower buds as those in snow country do. Lucky us. I?m looking forward to my hydrangea show which will last most of the year.
