Oakleaf Hydrangea – A Native Choice

Oakleaf Hydrangeas (Hydrangea quercifolia) make a beautiful choice for the home landscape.  They present great interest in all seasons of  the year.  Not only do they produce beautiful blooms in summer, but the plant also provides great fall color.  When making a choice for a new edition to your landscape, select Oakleaf Hydrangea !

Oakleaf Hydrangea is native to Southeastern United States.  I have personally observed hundred of Oakleaf Hydrangeas along streams and on the mountains at the Talledega National Forest in Alabama.  When I saw them they were dormant, as it was February, but it would be a magnificent site when they are all in bloom.

Oakleaf Hydrangea blooms are magnificent panicles that change throughout the season.  First creamy white color, turning to a pink and finally desiccating to brown.  There is something attractive about the brown dried bloom and it holds on for quite some time.  In winter, the exfoliating bark make it attractive even though it is without leaves.  This trait, along with the dried out bloom, make it enjoyable throughout the entire year.

So, You Have Alkaline Soil…

So, You Have Alkaline Soil…

So you have alkaline soil… What next?

Throughout the Panhandle, a common problem that often arises is finding a way to raise soil pH. This is due to the fact that we often encounter sandy, acid soils in this region. An often overlooked issue is explaining the process of gardening in a soil that tends to be more alkaline in nature.

Soil pH is measured using a scale from 0 to 14. On this scale, a value of 7 is neutral, pH values less than 7 are acidic, and pH values greater than 7 are alkaline. Soil pH directly affects the growth and quality of many landscape plants. Extreme pH levels can prevent certain nutrients from being available to plants. Therefore, a high pH may make it difficult to grow certain plants.

Often alkaline soils occur in the home landscape as a result of calcium carbonate-rich building materials (i.e., concrete, stucco, etc.) that may have been left in the soil following construction. Soils that contain limestone, marl or seashells are also usually alkaline in nature. There are a few measures that can be taken in order to combat high pH.  Incorporating soil amendments containing organic material is the most common method implemented to reverse alkalinity. Peat or sphagnum peat moss is generally acidic and will lower pH better than other organic materials. Adding elemental sulfur is another common practice. A soil test will need to be performed often in order to add the correct amount of sulfur to reach an optimal pH level.

Lowering the pH of strongly alkaline soils is much more difficult than raising it. Unfortunately, there is no way to permanently lower the pH of soils severely impacted by alkaline construction materials. In these circumstances, it may be best to select plants that are tolerant of high pH conditions to avoid chronic plant nutrition problems.

Some plants that will tolerate alkaline soils:

  • Shrubs

    • Glossy Abelia (Abelia Xgrandiflora)
    • Sweet Shrub (Calycanthus floridus)
    • Flowering Quince (Chaenomeles speciosa)
    • Burford Holly (Ilex cornuta ‘Burfordii’)
    • Indian Hawthorne (Rhaphiolepis indica)

American Snowbell: Native Flowering Shrub-Like Small Tree for Wet Areas in the Landscape

American Snowbell: Native Flowering Shrub-Like Small Tree for Wet Areas in the Landscape

Found throughout the North Florida Panhandle, the American snowbell, Styrax americanus, is a native small flowering tree.  In his book, The Trees of Florida, Gil Nelson describes the blossoms as charming with “the thin, reflexed (flower) petals curve back over the flower base, leaving an attractive mass of yellowish stamens protruding from the star-shaped corolla”. It has dark green deciduous foliage, with the tree reaching up to 16 feet in height.  The attractive blooms appear April – July.

Considered as an understory tree, American snowbell grows best in wet partially shaded areas and is somewhat tolerant of full sun.  It prefers wet places such as swamps, wet woods, edges of cypress ponds and moist to wet, cool, acid sandy to sandy loam soils.  Wet areas of the home landscape where water puddles occur provide adequate growing conditions for the American snowbell.

Wildlife benefits include nectar for bees and butterflies and edible fruit for birds. To try American snowbell in the landscape, check with local native plant nursery or search online.  Note: other Styrax species can be found online that are non-native.

Pecans – A Southern Tradition

As I made a visit back to my hometown in North Alabama I was reminded of the subtle changes from fall into winter, which are not always apparent to me living in Tallahassee: the vibrant palette of leaves as they make their permanent descent until spring, the litter of spent cotton along each highway and county road and the annual pecan harvest that has been a tradition in my family for as long as I can remember.

Due to the variations in climate and topography from upper Alabama to the panhandle of Florida, our seasons can differ greatly. However, I know of one entity that remains a constant and that is the availability of pecans. Pecan trees (Carya illinoinensis) are a common sight throughout the South. They can be spotted as far west as Texas and as far north as Illinois. The pecan tree is native to the Mississippi floodplain, which has deep, fertile, well-drained soils. Before the arrival of Europeans, Native Americans used pecans as a primary food source for thousands of years.

What’s more, pecans have major economic value. The annual value of pecans in the United States is estimated at 200 to 500 million dollars. Florida produces from five to ten million pounds of pecans annually. The majority of that pecan production acreage (6,500 acres) can be found in North Florida. While the nut is the main attractant of the tree, there’s not much that warms the heart more than seeing pecan pie at the dessert table on Thanksgiving.

Pecan trees are deciduous, which means that they drop their leaves in the winter. An additional consideration for those planning to install pecan trees is to  be aware that they are wind-pollinated and that their male and female flowers often do not mature at the same time. Therefore, in order to ensure the possibility of high yields, two or more cultivars should be planted together for cross-pollination.

Be sure to choose a variety like ‘Elliot’ or ‘Curtis’ that has good disease resistance, is suited for North Florida and will cross-pollinate well. Plant pecans during the colder months to allow for root growth before spring. The optimum soil pH for pecans is 5.5 to 6.5. At the lower end of this range, micronutrient deficiency symptoms should be less common. Pecan trees should start producing decent crops in six to twelve years. A tree at maturity can reach up to seventy feet tall so plan spacing and placement accordingly.

The Hickory: Tough and Durable Landscape Trees

Hickory nuts are popular with squirrels in the autumn.

Hickory nuts are popular with squirrels in the autumn.

There is a lot to be gained from having a tough reputation. Only those with a stout disposition or lack of good sense will dare to make a challenge to the individual who hold this distinction.

Unbending, rigid and durable are descriptors which invoke a firm, if not dogmatic, state of resiliency. With this enviable identity, many compare themselves and some assimilate the traits they most admire.

Andrew Jackson is a good case in point. The seventh president grew up on the frontier, dueled with enemies, and commanded an army during the War of 1812 where he was given the nickname Old Hickory.

Like Jackson, hickories are native to North America and are highly valued for their long wearing qualities. While this president no longer visits north Florida, there are plenty of hickories growing in home landscapes.

There are three hickories in panhandle Florida, bitternut, mockernut and water. The water hickory is usually found in wetter areas and the other two species in upland sites.

This genus, Carya, is found in North America and East Asia. The term identifying this genus was coined in Greek mythology and originally referred to a woman who was transformed to a walnut tree.

Karya, or so the story goes, was the daughter of a divinely well-connected king who had gained favor with Apollo. As a courtesy, Karya and her sisters were granted the skill of prophecy from the deity.

As is typical of Greek myths and soap operas, the sisters misused their gift of divination and were punished. Karya was turned into a walnut tree by her boyfriend who was the mythological god of winemaking and ritual madness.

Legendary tragedies aside, hickory trees have a wide variety of contemporary uses commercially and environmentally.

The wood of hickories is relatively hard and is used where a durable and sturdy material are required. Tool handles and flooring are two of the most common uses today.

Prior to the development of modern composite materials, hickory lumber was utilized in vehicle parts, golf club shafts, archery equipment, and a variety of other uses which anticipated hard use. Hickory was originally used to construct baseball bats until ash gained popularity because of its lighter weight.

Hickories are an excellent specimen tree in a landscape. These tall, deciduous trees usually grow from a single trunk and provide excellent shade during the summer.

The leaves can deliver a bright yellow show in the autumn and, if planted on the south side of a home, provide passive solar heating during the cooler months. Mockernut and water hickory nuts have been used in recipes, but are difficult to crack.

One caution is not to establish a hickory near a home or other structure. Squirrels will quickly identify the nuts as a food source and can be quite messy.

Another problem issue is if a tree falls during a storm. The logs are quite heavy and will likely crush anything they hit, especially homes and vehicles.

Hickory is popular and long burning firewood. It is also widely used by bar-b-q devotees who prize the distinct flavor it imparts.
