Vitex is blooming!

I love blue flowers, so I think that vitex (Vitex agnus-castus) is one of the prettiest of all our 'late summer' blooming plants. It usually flowers in August with the crepe myrtle and butterfly bushes. This year it is early and was bloom for July 4^th.  However, the way this tree blooms it goes on and on, as there are clusters of buds in many stages.  Ours is large and beautiful and such a good companion for a bright red crepe myrtle. This easy to grow shrub is such a good choice for awesome summer color.

When the spent blooms are cut off it may bloom again. There is faint lavender like fragrance in both leaves and flowers of vitex. The butterflies and hummingbirds love the blooms even more than I do. Vitex thrives in sunny conditions, with plenty of water, but at the same time, it grows well in drier environments and part shade conditions too. Most of ours are in sandy places of part shade. They are the most awesome plants in bloom now.  Vitex is known as tough and hardy and really easy to grow.   Vitex sheds all its leaves during the winter months, but has the interest of clusters of brown berries.

This colorful blue blooming plant was often referred to as 'chaste tree' by the Victorians and as monk's berry during the middle Ages. Legend said it suppressed libido, but it was also used to treat various hormone deficiencies. Who knows? (Plant folk tales are fun!)

Some scholars like Hippocrates are known to have recommended using the 'chaste tree' for treating conditions like injuries and inflammation, and several centuries later Dioscorides is known to have recommended the herb exclusively for treating inflammation of the womb and for encouraging milk flow shortly after birth.  The medicinal part of the plant is the berry that forms after the blooms fade. In Rome, vestal virgins carried twigs of chaste tree as a symbol of chastity.  The seeds were once called monk's pepper and were used among early monks as help against the evils of the fleshy desires.

For thousands of years it has been an important part of medical applications and even today studies are being done in Germany on the uses of this plant. However, I recommend that you plant one for its lush blue blooms that look so pretty in your garden.

Hydrangea

The cool blue of hydrangea is also pretty in a summer and fall garden. Remember, as their name indicates a hydrangea needs lots of water to bloom and look beautiful.  They appreciate some compost in the soil, a good drink several times a week and a light mulch to keep them moist. Let a hose or soaker thoroughly wet the soil to the bottom of the roots. Overhead sprinkling will sometimes ruin the blooms and mar the leaves on most plants. Soaker hose or drip irrigation work well.

To change pink bloom to blue adds acid or aluminum sulfate to the soil. This may take a while to work, but it really works. It will not change color of white ones.

There are many kinds of hydrangea; some of the late blooming cone shaped white blooms dry the best. If you have sun or shade these plants do well and add constant bloom for a long period of time.

Butterfly Bush

Fragrant nectar place for butterflies to visit.

Swallowtail drinks nectar from butterfly bush! 

Butterfly bushes (Buddleia) are very vibrant and also bloom from now until frost. The more you deadhead the spent blooms the more they will bloom.

If you plant this in full sun you will have the most blooms, but they will grow in part shade too. Remember they do not want to sit in muddy, clay, poorly drained soil. The blooms have an intoxicating scent that lures butterflies, hummingbirds and people to their vicinity. I love to pick a bouquet for my kitchen table. They can be found in white, deep pink, wine, and many shades of purple. 

Most get 5 -6 feet tall, but can be cut in half. They continue to produce blooms all the time with just a little fertilizer.

So if you do not have these summer bloomers plant some now. There is always room for a few more plants in your garden.

Old Fashioned Hydrangea

Old Fashioned Bloomer at its Peak  now Until Frost

Hydrangea bloom from now until frost!  A lot of plants reach a mature beauty and look vibrant in the strong light of late summer days when we lament the thoughts of frost  and they are one of them. One old-fashioned tree or shrub with huge puffs of white blooms is the P G hydrangea.  Sometimes it is in shrub form, but more often it is a shaped like a small weeping tree. This last to bloom of the entire hydrangea family it is properly called Hydrangea paniculata. One of its best cultivars is called P. G. for Paniculata grandiflora. But now I think I like the green hued on called Limelight. A glorious tree, with blooms at times touching the ground it is a wonderful specimen tree for a lawn or focal point in a garden.  They start to show blooms in late July with a greenish buds that turn snowy white in august and then a pale mauve in fall.      Some gardeners get confused with botanical names. But when they look at the name and realize that it actually describes the plant and tells them   what it looks like, they become more interested in scientific names. For instance, if your looked up paniculata you would find it comes from panicle which is defined as: 'a cluster of flowers on a plant consisting of a number of individual stalks (racemes) each of which has a series of single flowers along its length Or a loose branching pyramid-shaped cluster of flowers '.  

         Pee Gee or PG Hydrangea is another nickname given this plant.  It is well loved by generations of gardeners because in August and September it produces huge conical trusses of   flowers that are frequently from 6 to 18 inches long.  These often begin light green and turn rich creamy white and then fade gradually to shades of pink and then brown after frost. The foliage is a dark green that shows off the flowers nicely. When given the space P G   hydrangea makes a broad shrub to 12ft high and 10-15ft wide. Some gardeners prune it to keep it smaller. This is   best done while in bloom or just after bloom as it flowers on new growth.   If it is pruned in spring it must be very early before any new growth begins or blooms will be cut off.   

         Its blooms make a  splash of white when very few shrubs are in flower. It does look striking near red crepe myrtle and blue vitex for a real colorful summer display.   The plants do need moderate watering, especially during dry spells, but once established they are not a problem.     They have only a moderate tolerance to salt and really do much better in our somewhat acid southern New Jersey soil than in alkali soils. Like most hydrangea they do well in sun or   shade. Our plants do remarkably in shade and never cease to be covered with blooms. I rarely give it any supplemental water except when we have a long hot spell and then I soak it long   letting the hose slowly run for hours to be sure the roots stay deep and do not surface looking for easy moisture.

They bloom on current year's growth and should be pruned back hard each seasoning to develop a strong, woody framework to support the huge, heavy flowers.  We cut almost every single bloom, beginning to pick in late August and then continuing until late fall when all the blooms have been picked to dry and use in wreaths. Although all hydrangeas are valued as a good dried flower, these air dry best.  The colorful blue, pink and purple hydrangea of summer often dry best if placed carefully in silica, but PG picked late in the season can be simply hung and it will dry as is. The later they are picked   the more hardened off the blooms will be and the less moisture they will have in them.  We use them in wreaths, garlands and bouquets all throughout the year, Ones that are left long into fall and turn beige can be touched with gold or silver spray at holiday time and hot glued on wreaths or swags if you like a elegant gilded look.  They work well into Williamsburg, Victorian or contemporary designs.

They can be planted mo fall but it is important to water well so that the root balls secure and the tree will not tip over in winds. Sometimes it is a good idea to stake these if they are a bit top heavy.  I think they are extremely easy to grow. Other than a handful of 10-10-10 each spring and a hose once or twice a month in summer we do nothing but enjoy the display of blooms on this long blooming plant.
