Trees for Shade, Wildlife and the Future

We don?t plant enough trees. Everyone wants an instant garden but nature doesn?t work that way. When you look out from your windows into your landscaping what catches your eye first? I’ll bet the most majestic and inspiring sight in your garden is probably a tree that frames your house giving it a sense of permanence, welcoming you home and providing a haven for songbirds that serenade you on a summer day.

Large or small, trees make the world go round. They produce oxygen and act as a giant filter that cleans the air we breathe. A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year.

Trees clean the soil by absorbing dangerous chemicals and other pollutants that have entered the soil. They can either store the harmful pollutants or actually change the them into a less harmful form. Trees can filter sewage and clean the water that runs off into our streams. They can absorb and lock away carbon dioxide as wood so it is not available as greenhouse gasses.

If you live near a busy street trees can muffle the noise almost as effectively as a stone wall. They also act as a windbreak during windy and cold seasons reducing the drying effect of the wind and keeping it from blowing precious topsoil away.

Gingko biloba

Trees slow storm water runoff which helps recharge our aquifers. On top of all the beneficial things trees do for us they provide shade and keep us cool in the summer. In the winter they break up the wind reducing heating costs. Trees increase property values. If you’ve been thinking about adding a few trees to your own property here are some of my favorites. Some don’t get enough recognition others are classics. All make great additions to the garden.

I like Forest Pansy redbud for its stunning red foliage, Sango Kaku Japanese maple for its year round interest, Strawberry tree, and Tristania laurina Elegant. Evergreen Dogwood, Cornus capitata, is also known as Himalayan flowering dogwood lives up to its name in every respect. This variety is slow growing reaching 20 ft tall in sun or partial shade after about 25 years. After flowering, red fruit provides a treat for the birds.

To make your garden more compelling also consider planting a Ginkgo biloba ?Autumn gold? or Amelanchier ?Autumn Brilliance?. Also called Apple Serviceberry it has edible small fruits you can use in jam and grows fast. Chinese Fringe Tree has magnificent clusters of fragrant, fringe-like blooms and is a terrific accent for small yards.

Swan Hill olive

We are all familiar with the huge flowers in late winter of the Saucer magnolia. This beautiful tree also makes a good lawn tree. Oklahoma redbud takes heat and drought but can also tolerate regular garden watering. Chitalalpa ?Pink Dawn? grows 12 feet in three years then grows more slowly to 25 feet with a 25 foot spread. It?s pink trumpet shaped flowers are a welcome sight during the summer. Crape myrtle also blooms at the same time providing your garden with color when you?re outdoors the most.

?Swan Hill? olive produces no pollen or fruit, takes drought conditions and casts light shade. Chinese pistache provides brilliant fall color growing to 35 feet by 30 feet wide.

Plant a tree for yourself and for future generations.

 

Interesting Plants to Update your Garden

Tired of seeing the same plants in your garden and everywhere else? Feel like changing things up a bit? With this question in mind I?ve turned to my fellow landscape designers to see what plants they are using these days so that every garden they design doesn?t look the same. You can have too much of a good thing.

One thing I know for sure is that I don?t want to recommend a plant that hasn?t been shown to be a reliable grower in a variety of conditions. Sometimes the latest and greatest plant introduction turns out to be a dud. Other times a new cultivar of an old favorite hits a home run. Here are some oldies but goodies and new plants to add to your garden.

 

Loropetaum ‘Jazz Hands Dwarf PInk’

Loropetalum ?Jazz Hands? is getting the nod from everyone who?s grown it. If you love the deer tolerance, low maintenance. moderate watering and toughness of regular Chinese Fringe Flower this showy dwarf variety is even easier to grow. Staying low and tidy Jazz Hands Dwarf Pink has cool purple foliage with a cranberry undercurrent and hot pink blooms. It looks great combined with Jazz Hands Dwarf White. Local wholesale nurseries are growing it so it?s readily available.

Speaking of local sources for plants, we live in one of the prime growing areas for landscape plants. I recently learned that one of my favorite plants Canyon Snow Pacific coast iris is going through a difficult time. Seems it?s become less vigorous than the other colors in the Canyon series and the growers are working to improve their stock. We need to count on a plant?s performance. There?s enough other issues to deal with in our gardens without starting with a wimpy plant.

Cistus variegata ‘Mickie’

Rockrose have always been favorites in the low water use garden. There?s one with a low, mounding habit that hugs the ground and creates a super colorful accent to the sunny garden. With brilliant gold leaves splashed in the center with green this variegated cistus hybridus called ?Mickie? is hardy in winter, grows only 14-18 inches tall and spreads to about 2 feet wide. Perfect for containers or smaller gardens.

If you like to include California native plants in your garden Woolly Blue Curls or trichostema lanatum has been shown to be reliable in the garden if given full sun, good drainage and little fertilizer or amendment. Group similar plants and forget about them. They bloom from late spring through summer and make a good cut flower. Another common name for this plant is Romero or California Rosemary which dates back to the Portola expedition in 1769.

If you want to make a big splash in your garden or container try growing Salvia ?Amistad? or Friendship Sage. With fast growth in the warm months to 4 or 5 feet tall, the rich royal purple flowers attract hummingbirds and butterflies to the garden. It will grow in light shade with medium water requirements and remain evergreen in warmer parts of your garden.

Cousin Itt acacia

Acacia ?Cousin Itt? continues to be a favorite for many of us. This lovely small plant with emerald green, feathery foliage that stays small in the garden and has low water needs. Not to be confused with the bully acacia tree seen around here, it?s one of the good guys. Plant in full sun to partial shade.

So if you?re in the mood to add a couple of interesting plants to your garden, take a tip from what landscape designers use or grow in their own gardens.

How to Live in Peace with a Wisteria

A wisteria is one of those plants that you either love or dread. One of nature?s most resilient survivors they are able to withstand and recover quickly from difficult conditions. To some they are a little too tough for their own good with a growth rate rivaling bamboo during the summer. If you dream of a wisteria-covered pergola shading your patio here are some maintenance tips that are sure to keep both gardener and vine happy.

Wisteria at Filoli Gardens in Woodside

Wisteria are so vigorous they can be pruned at any time, keeping them in bounds and to clear out unwanted or dead growth. Prune out any stems you see extending into eaves, windows or shingles. If yours has gotten away from you, you can even prune it down to the ground and start over with training although you?ll have to wait a few years for your vine to bloom again.

To their control size major pruning is done during the dormant season. Start by trimming the long tendrils that grew over the summer back to about 6 inches from the main trunk. Cutting the tendrils back in this way will initiate flower bud development, neaten the plant up, and show off the attractive trusty, gnarly character of the vines.

Pruning during the dormant season will also give you a fighting chance of keep your wisteria from getting into mischief. As you know if you have a wisteria, those long tendrils are capable of growing another 25 feet during the summer.

Whatever time you do renovation pruning remember the response of the wisteria to aggressive pruning is to literally explode with new runners. They put energy into new vegetative growth at the expense of flowering. Make sure you keep up on ongoing maintenance pruning by removing all unwanted runners right to their point of origin. Then prune back the others to 3 buds or sets of leaves. Repeated pruning of these runners is what will eventually give you spurs of wood, short laterals that in turn will provide you with flower clusters. You need to prune these runners all season long which ends up being every 3-4 weeks.

Do not fertilize your wisteria. They do not flower well is there is an over abundance or luxuriant growth. Over feeding also ends up giving them the means to become un unmanageable monster. If you find the wisteria vine has invaded a nearby bed, cut roots with a shovel below the soil line to control any that have wandered.

Maintaining a wisteria requires some diligence but the reward is worth the effort. Remember this especially during winter pruning season to make summer maintenance easier.

Cooke’s Purple wisteria

Which variety of wisteria should you get to cover your arbor, pergola, tree or other structure?

Chinese varieties such at ?Cooke?s Special? has clusters of fragrant blue-purple flowers 20 inches long. This variety can re-bloom which makes it a favorite.

Japanese wisteria ?Caroline? blooms early with mauve flowers. ?Royal Purple? (also known as ?Black Dragon?) has sweetly scented dark purple flowers. Japanese wisteria are most effective when grown on pergolas so the long flower cluster can hang freely.

Silky varieties produce a profusion of short, 6 inch, fat clusters of strongly scented flowers that open all at once. They have velvety seed pods and bloom best in full sun.
