Eddie’s White Wonder

It’s a wonder that more people don’t grow and enjoy ‘Eddie’s White Wonder’ Dogwood. It has been commercially propagated and available in the trade since 1955, ten years after it was discovered by Henry M. Eddie, a Vancouver, B.C. nurseryman.

The “white wonder” part of the name refers to the prolific, attractive white blossoms that the tree produces in spring. The big, beautiful white flowers grow to more than four inches in diameter. Composed of four to six large, rounded and overlapping bracts, these blooms create a striking display.

Its dark green foliage is handsome throughout the summer months, and in the fall, it turns a brilliant, rich red. Small red fruits decorate its branches in winter and attract robins, mockingbirds and cedar waxwings.

Dappled sunlight illuminates the showy blooms of ‘Eddie’s White Wonder’ dogwood. A hybrid of the Pacific Northwest native dogwood, Cornus nuttallii, and the Eastern dogwood, Cornus florida, it grows taller and has larger flowers than Cornus florida. It is also easier to grow, more resistant to anthracnose, and generally more adaptable than its other parent, Pacific Dogwood.

Upright and rather pyramidal in form, with slightly pendulous branches, ‘Eddie’s White Wonder’ grows to a height of about 25 feet with a spread of 15-20 feet. They grow naturally in partial shade, but will also grow in full sun with ample summer watering. Too much shade will cause them to produce fewer flowers.

They prefer well-drained, acid soils high in organic matter and like evenly moist soil conditions, but will not tolerate standing water. Be sure your site is well-drained even in the winter.

Dogwoods are low maintenance trees. They should only be pruned after flowering to avoid removing any of the current season’s flowers. Careful thinning will enhance the horizontal branching pattern but improper pruning can ruin the lovely layered effect. Remove crossing limbs when in flower and use the lovely cut branches for house decorations.

The flowering of ‘Eddie’s White Wonder’ is somewhat dependent upon the previous years summer weather. After a long hot summer, the spring flowering will be magnificent, so they generally bloom very well in our area.

‘Eddie’s White Wonder’ is a fine specimen tree planted in a prominent corner of the yard. It looks lovely planted with Lily-of-the-valley shrub, Pieris japonica, variegated holly bushes and evergreens. And you can surround it with lush, bold Hosta plants, which will form a ground cover and act as a living mulch.

Dogwoods have special interest every season of the year – in spring with beautiful flowers; in summer with attractive, healthy foliage; in fall with brilliant red berries and vivid autumn color; in winter with their picturesque horizontal branching pattern. Find a place for ‘Eddie’s White Wonder’ in your landscape.

The Secret Life of Ladybugs

Ladybugs, also called lady beetles or ladybird beetles, are magnificent creatures. They are predators and are natural enemies of many insects, especially aphids and other sap feeders. A single lady beetle may eat as many as 5,000 aphids in its lifetime. In addition to aphids, ladybugs eat a variety of other insects and larvae including white flies, mealy bugs, spider mites, and other types of soft-bodied insects.

In California we are familiar with Convergent Lady Beetles. They are dome-shaped and have red wings with the usual 13 spots, or sometimes none. One or two generations occur each year before the adults go into hibernation, usually in mountain valleys far from food sources.

Adult females usually lay clusters of eggs on plants in the vicinity of aphid, scale, or mealybug colonies. Females may lay from 200 to more than 1,000 eggs over the summer. In two to five days, the eggs hatch and alligator-like larvae appear. They are spiny and black with bright orange spots on their backs and, although they look dangerous, they are quite harmless to humans. They are excellent predators and, while adult ladybugs tend to move on once pests get scarce, the larvae remain and search for more prey. They have a voracious appetite for aphids and feed for 3 to 4 weeks before they pupate and turn into young adult ladybugs.

You can purchase ladybugs from most nurseries in the spring and early summer. Before releasing them into your garden, here are a few tips to help ensure that the ladybugs stay where you want them:

1. Release ladybugs near infested plants after sun down or before sun up. They navigate by the sun and are most likely to stay put in the evenings and early mornings.

2. Water the area where you are going to release the ladybugs. They will appreciate the drink and the moisture on the leaves will help the ladybugs to “stick” on the plants. If released in a dry garden, the ladybugs will most likely fly off in search of a drink instead of sticking around to eat.

3. In warm weather, chill the ladybugs in the refrigerator before releasing them. This will not harm the ladybugs and they tend to crawl more in colder temperatures rather than fly away.

Do not release too many Ladybugs at one time. Try to keep a balance of pests and Ladybugs so that they have something to eat. Release a few at a time each night when leaves are young, tender and attractive to aphids.

Greenhouses often attract aphids and other pests due to warm humid conditions and abundant food. Releasing ladybugs into a greenhouse with screened doors and openings will keep them inside where you need them.

As winter approaches, lady beetles migrate to the Sierra Nevada Mountains where they congregate in large numbers before moving off to hibernate under nearby pine needles and leaf litter.

Throughout the world ladybugs are a symbol of good luck. And they will bring “good luck” to your garden by keeping it clean of undesirable pests.

• Begonias bulbs can be started indoors now and set out after danger of frost. You’ll enjoy their beautiful flowers this summer.

What’s New?

“It’s Spring again, and birds on the wing, again…” Spring is finally here and we’re all looking for something new and unusual to brighten up the yard.

Daisies are always fun and offer their bright flower faces up to the sun. The ‘Margarita Bronze Bicolor’ Osteospermum dairy is a most unusual color. This bronze African Daisy has long, ridged, daisy-like petals of a rosy-bronze with a halo of pastel yellow surrounding the dark eye. It is really striking and a perfect addition to your flower arrangements. It’s sister plant, ‘Margarita Pink Flare,’ has rich, pink flowers with a white center that “flares” out from the dark blue eye. Growing 12-15 inches high, they will look nice planted with white alyssum.

A new group of Nemesias are called Sunsatia® and their ‘Raspberry’ is a rich, warm color. Nemesias are related to snapdragons and grow in part sun, with abundant raspberry-pink flowers all through the spring season. Growing 12-18 inches tall, they can be used in flower beds or as fillers in combination pots.

For a really big splash, try the new Sunbather® Gazanias. This new generation from Australia have a dense growth habit and large brightly-colored flowers. ‘Sunbather’s Sunset’ offers amber-orange double flowers that stay open day and night. It grows 18 inches tall and wide, and loves the full, hot sun.

Now, for something really different, you’ll have to see the new Supertunia® ‘Pretty Much Picasso’®. Its unique flowers are rose pink edged in lime green with a dark purple eye. The vigorous plants are great for mixing in combination pots. They will grow 8 inches tall and 12 inches wide. Try them with Lysimachia, an evergreen groundcover with rounded, yellow-green leaves, and white alyssum.

Another great new petunia is ‘Double Cascade Blue.’ Floriferous and cascading, the dark purple-blue double flowers cover the large, vigorous plants. Mix them with double ‘White Sonata’ or single pinks for a showy combination.

New varieties are always coming out in Impatiens. As part of the new Dazzler™ series, we now have ‘Lilac Splash’ and ‘Blue Pearl.’ Dazzlers™ put on a big show of 1.5-in. blooms over rich, green foliage all summer long. The flowers of ‘Lilac Splash’ are a deep lavender-pink with a red eye, and ‘Blue Pearl’ is more of a light magenta with a purple eye. Both will brighten up your shady flower beds and pots.

Don’t overlook snapdragons for taller plants in the flower border. A new series called ‘Freesong’ grows up to 18 inches high. The well-branched plants make excellent cut flowers in cherry, crimson, pink, scarlet, white, yellow and orange.

Spring is here and it’s time to get planting!
