Look up Oleander for comparison. Not too sure here. But there is a lot of it grown in landscaping of hotels near Myrtle Beach SC. If it is then use caution as all parts are poisonous.

Oleander

Oleander flowers are beautiful, but the plant is deadly.

The oleander, or Nerium oleander, is considered by many to be the most poisonous plant in the world. All parts of the beautiful oleander contain poison -- several types of poison. Two of the most potent are oleandrin and neriine, known for their powerful effect on the heart. An oleander's poison is so strong, in fact, that it can poison a person who simply eats the honey made by bees that have digested oleander nectar.

The oleander is an attractive plant, and despite its deadly reputation is often planted for decorative purposes. Although native to the Far East and the Mediterranean areas, oleander has been introduced in the United States, where it grows easily. It's tolerant of poor quality soil and dry weather. The plant grows as a dense shrub, and is typically 6 to 18 feet (1.8 to 5.4 meters) tall at maturity. It has thick, dark green leaves, and the flowers, which grow in clusters, can be yellow, red, pink or white. Even in barren areas, the oleander produces lovely flowers and fragrance. Animals instinctively avoid the plant, and it grows rapidly, so it's often used for highway barriers and other areas that require screening from noise and pollution. Its rapid growth also makes it a popular choice around new construction zones, as it prevents erosion.

Unlike some toxic plants, the oleander is poisonous to most animals as well as humans. A single ingested oleander leaf can kill a child. Ingestion of oleander results in diarrhea, vomiting, intense stomach pain, drowsiness, dizziness, an irregular heartbeat, and often, death. If the victim survives the initial 24 hours after ingestion, his or her odds of surviving increase dramatically. For successful treatment, the patient is induced to vomit, his or her stomach may be pumped, or he or she may be fed activated charcoal to absorb as much of the poison as possible.

Thanks. It sure fooled me.

Myrtle Beach ..... hint, hint.

Pacific wax myrtle is a very common screening shrub used extensively all along the Pacific coast. It grows fast and well with minimal attention and has a much greater range of cold tolerance than does the Nerium/oleander. I'd suspect the plant seen in Myrtle Beach is also a type of eastern wax myrtle - there are several - as I doubt the oleander would survive long term in that location. Not sufficiently cold hardy.

Interesting. They won't survive long term here and I am in an equally mild climate zone, if not an even milder one!!

Oops. I should have given Florida as an example. They have plenty of Oleander. I visit there more often. I haven't been to Myrtle Beach in 20 years and would not have paid attention to the exact plantings then.

Florida for sure for oleander :-) And for most of California. But the further north you go and the lower the hardiness zone drops below 9, the less chance of winter survival. Even a few days at temps lower than 25-20F (zone 8), foliage will be cold damaged and latent flower buds frozen. More than a few days and the plant can be killed back to the roots or worse.

As a Mediterranean plant, Nerium oleander likes hot, dry summers. Among its many varieties, only a few are hardy below Zone 8. 'Hardy Red' and 'Hardy Pink' are more popular. We have had troubles with 'Hardy Red' in the cold winters when the Zone 7b minima were reached, but this may have been due to poor siting (too much shade), so we keep trying. PDN sells 'Mathilde Ferrier' and is quite assertive of its Zone 7b hardiness. There are also several European varieties grown successfully in Germany and Austria.

Oleander flowers do not produce nectar, hence no honey is made from them.

Oleander roots will seek out pipes and can be destructive. They also can sucker from roots.

My apologies to the OP. I did not mean to hijack your post.

These helpful folks can surely advise you on growing myrtles.
