This flower hue adds vibrance to summer landscape

Stokesia comes in many cool

shades.

Blue ranks among the rarest colors in the summer garden. Yet it's a beautiful contrast to all of July's other brilliant colors, especially yellow and orange.

Blue stands out in the landscape, immediately drawing your attention. Bees seem to gravitate to it, too.
The one trait most blue flowers share is they contain anthocyanin, the same pigment that makes blueberries blue.

As an accent or in broad borders, blue blooms complete a flowery summer rainbow. An Independence Day bouquet wouldn't have the same sparkle without some blue.

Just in time for Fourth of July and midsummer, here are the blues blooming in my Sacramento garden right now:

Hydrangeas: My true blues are just coming into their bloom cycle. By late July, they'll be covered with great soft mounds of baby blue. Formerly pink hydrangeas can go blue, too, by slightly increasing the acidity of their soil.

Stokesia: This low-growing perennial blooms from early July until frost. It comes in several shades of vivid blue from powder to deep cobalt. My variety: Blue Frills from Proven Winners. It contrasts beautifully with orange coppertips ( Crocosmia ) and yellow daylilies. Stokesia also makes a good cut flower; pair it with white daisies and red roses or gladiolas for a charming red-white-blue bouquet.

Agapanthus blossoms attract bees.

Lilies of the Nile: My huge agapanthus clumps came with the house. But the bees love them, so they stayed put. Every Fourth of July, the gigantic flowerheads look like blue fireworks exploding among the roses. Another plus: They make good cut flowers and add the blue to my Independence Day bouquets. The dried stems also are attractive in arrangements.

Borage, a blue herb, has edible flowers.

Borage: This blue herb is a bee favorite in my vegetable garden and the intensely blue (and slightly spicy) flowers are edible. Use them as decorations on cakes and cupcakes.

Garden Checklist for week of Nov. 3

November still offers good weather for fall planting:

* If you haven't already, it's time to clean up the remains of summer. Pull faded annuals and vegetables. Prune dead or broken branches from trees.

* Now is the best time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from fall and winter rains.

* Set out cool-weather annuals such as pansies and snapdragons.

* Lettuce, cabbage and broccoli also can be planted now.

* Plant garlic and onions.

* Keep planting bulbs to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.

* This is also a good time to seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.

* Rake and compost leaves, but dispose of any diseased plant material. For example, if peach and nectarine trees showed signs of leaf curl this year, clean up under trees and dispose of those leaves instead of composting.

* Save dry stalks and seedpods from poppies and coneflowers for fall bouquets and holiday decorating.

* For holiday blooms indoors, plant paperwhite narcissus bulbs now. Fill a shallow bowl or dish with 2 inches of rocks or pebbles. Place bulbs in the dish with the root end nestled in the rocks. Add water until it just touches the bottom of the bulbs. Place the dish in a sunny window. Add water as needed.

* Give your azaleas, gardenias and camellias a boost with chelated iron.

* For larger blooms, pinch off some camellia buds.

* Prune non-flowering trees and shrubs while dormant.

* To help prevent leaf curl, apply a copper fungicide spray to peach and nectarine trees after they lose their leaves this month. Leaf curl, which shows up in the spring, is caused by a fungus that winters as spores on the limbs and around the tree in fallen leaves. Sprays are most effective now.
