• Fragrant star jasmine is in full bloom right now. Plant one in a semi-shaded spot where you can enjoy its lovely perfume.

• Hydrangeas have giant pink or blue flowers. They will brighten the shade garden all summer.

• Remove suckers on rose bushes. These vigorous canes emerge from below the bud union and should be cut off as far down as possible.

• Colorful petunias will brighten up any flower bed. Their purples, pinks and reds make a real splash when planted in groups of the same color.

Herbs in the Landscape

Although many people think that herbs belong on the windowsill or in the vegetable garden, herbs also make fine landscaping plants. Many attractive shrubs and ground covers are herbal plants that can add beauty to the landscape while providing foliage and flowers for herbal uses.

Herbs are generally easy to grow and require less watering and attention than most other plants. Their aromatic oils make them relatively immune to insect attack, and for this same reason, deer usually leave them alone. Their fragrance in the garden is another reason to make use of them.

Some low-growing herbs make good lawn substitutes in small areas and around stepping stones. Chamomile and woolly thyme are very good in sunny areas. They can be mowed occasionally if they get taller than you want. Corsican mint, which forms a moss-like mat, in sun or partial shade emits a very strong, pleasant odor of mint when lightly brushed. It is the mint used to flavor liqueurs.

Creeping thyme, lemon thyme and silver thyme are very drought tolerant and make a mounding mat for full sun. Prostrate rosemary grows about 18 inches tall and is excellent for planting on hillsides and for draping over walls. All types of rosemary can be used for culinary purposes and are very deer resistant.

Lavenders, upright rosemary and sage are all lovely shrubs for dry sunny areas. There are many types of lavenders to choose from that grow between 18 inches and 4 feet tall. Lavender can be used as a foundation plant or to create a hedge and will still provide you with delightfully flavored flowers and leaves.

Upright rosemary can grow to 4 to 6 feet tall and makes a nice clipped hedge. Culinary sage has gray-green leaves. There are also varieties with variegated yellow and green leaves, or silver and purple leaves. They make a small mound, about 2 feet tall.

Santolina, or lavender cotton, is a gray, mounding plant that is useful for borders. Catmint has soft, gray-green foliage and lavender-blue flowers that make a showy display.

Foliage is one of the most interesting aspects of herbs for landscaping. Several members of the artemesia family are particularly striking with their silver or gray leaves. Artemesia ‘Powis Castle’ has finely cut, silver-gray foliage that is fragrant and it makes a fine background plant at 3 feet tall. Germander makes a low mound with small rosy-purple flowers in dense heads.

One of the largest herb plants is the Mediterranean bay laurel, Laurus nobilis. It is an evergreen shrub growing 12 feet tall in a dense, tapering cone. This shrub has the bay leaves used in cooking, and it makes a good screening plant.

Two of the most interesting flowering herbs are bee balm (also called monarda and bergamot) and purple coneflower. Bee balm leaves make a fine tea, and purple coneflower, the familiar echinacea of many herbal remedies, is a long-blooming perennial that can be a great addition to any garden. It is great favorite of monarch butterflies and should be in every butterfly garden.

While most herbs prefer a sunny location, many will do well in part sun or shade. Sweet woodruff — used in potpourris and as a moth deterrent — is an excellent shady area ground cover that cares little about soil conditions.

Whether you want a formal herb garden or a hillside of fragrant herbs, you’ll find herbs to be useful and attractive plants for landscaping.

• Dig gently to harvest potatoes, a few plants at a time, after foliage yellows and dries up.

• Roses need water and fertilizer to keep blooming through the summer. Watch for pests and diseases and treat as soon as you see trouble.

• Birdbaths will attract our feathered friends to your backyard so you can enjoy them close-up. Place them a few feet from a bushy shrub to give the birds protection.

• Zinnias love the heat and will add a rainbow of color to your garden and the deer don’t like them.

• Garlic should be harvested when the leafy tops turn yellow and fall over; air-dry bulbs, remove tops and store bulbs in a cool place.

Solve Landscaping Problems with Vines

All vines scramble or climb, but that’s where their similarity ends. You can grow vines for shade, for food, or for beauty of foliage, bloom or fruit. Vines range from tough, woody grapes, wisterias and trumpet vines to annuals like morning-glories and sweet peas. Add in clematis, ivies and Virginia creeper and you have lots to work with.

Are you bothered by an unsightly view? Vines can be used to cover up unsightly views or structures. Does your deck or patio broil in the noonday sun? A vine planted to grow over an overhead structure can provide welcome, cooling shade much quicker than a tree can.

Vines are used to soften and connect the hard edges between structures and plants in a garden. Wisteria or grapes can be used to cover a sturdy trellis linking the house with the garden. Or they can climb over an arch or pergola to form a green entrance or walkway. The drooping clusters of wisteria’s fragrant flowers are beautiful in the spring.

Plant vines to screen unsightly walls or views. A well placed vine can provide the same amount of privacy as a tall shrub, while taking up less horizontal space. For this purpose, be sure to choose evergreen vines, and train them to cover a trellis thickly. You can also extend the height of a typical 4-6′ privacy fence by adding trellising materials and an evergreen vine.

Virginia creeper, which attaches itself to walls with little suction cups, is excellent for covering plain walls or fences. In the fall, it turns a brilliant scarlet before dropping its leaves. Climbing hydrangea is a large vine that also climbs with suction cups. Its white flowers are very showy in summer in partial shade, though the vines will tolerate full shade, but bloom less.

Star jasmine or Carolina jessamine are very attractive planted by lampposts and pillars. They are both evergreen and will eventually cover the post completely.

The deciduous clematis have wonderful displays of flowers in spring or summer. They can be used to climb fences and trellises.

A chain-link fence can be turned into a beautiful green wall with vines. Orange trumpet vine or Virginia creeper will give a lush green look all summer but be bare in winter. Ivy or evergreen clematis will hide the fence permanently. Honeysuckle is partly deciduous but covers well and spreads its lovely fragrance over a large area.

Annual vines are generally overlooked for their landscaping qualities. Planting annual vines on fences, gates and other structures quickly brings an established look to a young garden. Create summer shade on a porch with a string trellis covered with vines. Try morning-glories, scarlet runner beans, and moonflower for eye-catching summer color. Hops vines make a beautiful green covering but die to the ground each winter.

Look to versatile vines to help solve many of your landscaping problems.

• Dress up for the Fourth! Red, white and blue petunias, verbena or combinations of these with lobelia, geraniums, impatiens and salvia will make a nice display for the Fourth of July.

• Plant fresh herbs from young plants. Basil, rosemary, thymes, mints and sages are just a few ideas.

• It’s time to set out Brussels sprouts for fall harvest. Plant lettuce every two weeks for fresh heads all summer.

• Check young trees and fruit trees for suckers and water sprouts. Rub suckers off as they appear and cut water sprouts off apple and pear trees.

• Roses are in their glory now. Choose a new rose bush or climber to add to your flower garden or brighten up a wire fence.

Plant a star in your garden

One of the most popular landscape plants in California is known as star jasmine. Actually there are two star jasmines. The commonly planted one is Trachelospermum jasminoides, and the other is the Asian star jasmine, T. asiaticum.

Star jasmine has long been prized for its wonderful fragrance. It normally blooms through June and July with scattered flowers on through the summer. The flowers are about an inch across and are borne in clusters at the ends of the branches. The glossy, dark green leaves make an attractive contrast.

Star jasmine is a plant that can be trained to do almost anything you want. It will climb a trellis, spill over walls, climb fences and drape from hanging baskets. It is also a very graceful ground cover forming a thick cover about 18 to 24 inches tall.

Since it is slower growing than most vines, it is far more suitable for the small private garden or backyard. It can be grown in a large container for many years. Let it grow up a trellis to make a screen for the patio.

To cover a fence or wall, set the plants about 3 feet apart and start them in the direction you want them to grow. They climb by twining, but you may have to tie them to a trellis to start them growing up. As the plants mature, they grow faster, and can be trimmed lightly to keep them from becoming woody.

Asian star jasmine sends out long trailers on young plants and can be trained right away. It is more hardy to cold, but the flowers are a little smaller and more cream-colored than its cousin.

If you want to plant star jasmine as a ground cover, set the plants two feet apart. Use a diamond-shaped planting plan to assure good coverage as soon as possible. Any shoots that seem to grow straight up should be removed so that growth can go into the trailing shoots.

It is best to plant star jasmine where it receives afternoon shade. Hot sun can burn the leaves. Keep them well watered and weeded. A program of feeding every spring and late summer will help them grow and cover as soon as possible. It is slow to take off growing so if you want to cover an area quickly, you might want to start with a larger plant.

Both star jasmines are good-looking all year, and make a nice backdrop for other flowering plants. Use star jasmine near an entry or along a walk so you can enjoy the wonderful fragrance of their star-like flowers.
