Gardeners love to share plants. My yard, like many of my gardener friends, is filled with plant gifts that were started from a cutting or division of a favorite plant. These two methods of growing new plants is fairly easy once you learn the techniques and allows gardeners a way to save a little money and grow more plants for their yard, special community projects, or even some fundraising events.
In our enthusiasm over a favorite plant, gardeners must be aware that we are not allowed to propagate certain plants from cuttings or division. Many of our ornamental plants, especially newer introductions are patented plants. These are seen as ‘premium’ plants that will hopefully be in demand by the public. The plant developer or nursery invests in the patent in hopes that the plant will become the next must have ornamental. Only businesses or individuals with authorization from the patent holder are able to asexual propagate these plants since the Plant Patent Act protects these new varieties for 20 years from the date of introduction.
So if you bought a beautiful Limelight hydrangea (Hydrangea paniculata ‘Limelight’ Plant patent #12,874) for your yard, you may not take a cutting to start a new plant, even if it is only for yourself.

When you visit the nursery, look on the plant label which will often indicate if the plant is patented. You may also look online to see if plant has a patent.

Believe it or not, there is a beneficial ant that is found in many landscapes. If you see an interesting mound shaped like a small volcano, you likely have the pyramid ants. These ants form small nests in sandy soils and the mound will have a small opening in the very center.

Pyramid ants are not aggressive and do not sting. They are fast moving over the ground building the mound and searching for food. Ants will collect honeydew from other insects and the beneficial part is that ants hunt live insects including winged fire ants. By allowing the pyramid ants to remain in parts of your landscape, you may reduce the numbers of fire ants that can establish in that area.
When you see the distinctive pyramid ant mounds, remember the beneficial role they play in keeping pest species in check. Keep any baits away from these areas to protect the pyramid ants.

The mining bees or adrenids are often seen in areas of landscapes that have little ground vegetation and loose soil. After mating, the female bee will excavate a very small tunnel in the ground that has several small cells attached to it.

The bee collects pollen and nectar to add to the cell and then lays a single egg in each cell. The emerging larvae feed on the nectar and pollen until it changes to an adult bee in the fall. There is only one generation a year. Although these solitary bees individually produce small nests, sometimes many will nest in close proximity to each other.

Solitary bees are not aggressive and stings are quite mild. Most solitary bees can be closely observed and will elicit no defensive behaviors. Perhaps the most common stings that occur are when the sweat bee, which is attracted to moisture, stings when swatted. Males of some solitary bees, which can not sting, will sometimes make aggressive-looking bluffing flights when defending a territory.
Like the most famous honey bee, solitary bees play a beneficial role in the pollination of plants. Their activity in the spring is short-lived and no management is necessary.

A common question about insects when cold temperatures arrive is whether or not the cold will kill many pests. Although temperatures will occasionally drop below freezing in north Florida, it is normally not cold enough to significantly impact insect populations for the upcoming year.

Even when we do receive a significant amount of cold weather, insects have many methods to survive weather changes. Some insects survive by moving to micro-habitats that are more resistant to temperature fluctuations. Beetle larvae may move deep in the soil or into logs and trees for protection. The grubs can continue feeding on decomposing material throughout winter months. Beneficial insects such as dragonflies and damselflies stay protected in their nymph forms in the mud of ponds and lakes.
One of the most famous insect survival strategies is migration. We are all familiar with the late summer and fall flights of the monarch butterfly to warmer regions of Mexico and southern California. Those butterflies and moths that do not migrate have their own survival techniques. They will overwinter in protective pupal cases to emerge as adults in the spring. Moth cocoons are spun of silk and may be composed of multiple layers, making them a good protection for the transforming insect.
Insects are adapted for survival and can live through far colder winters than we experience. Even though our cold weather will not drastically change insect populations, periods of cold will at least slow down their activity enough for us to enjoy a break from many pest worries.

Magnolias are well known plants to gardeners and many are familiar with the foliage and flowers of these plants. If you are looking for another earlier bloomer, you may want to consider adding a specimen selection to your landscape, the Star magnolia (Magnolia stellata).
Although not native to the United States, star magnolia is a slower growing multi stemmed deciduous shrub reaching about 15 feet in height over time. The best feature are the bright whitish pink star-shaped blooms appearing in late winter before leaves emerge. The flowers offer gardeners a peek of the spring to come and remind us that our Gulf Coast winters are not that long. 
Plants do best in soil with some organic amendments and mulch over the root systems. A planting area that receives a little afternoon shade is ideal but established plants will adapt to sunnier locations when irrigation is provided during drier weather. Only occasional pruning is required to remove crossing branches or those that grow out of bounds. Prune after flowering if needed.
