Is Lobelia poisonous to humans?
Lobelia poisoning occurs when your dog consumes parts of the lobelia plant and is exposed to lobeline, the plant's toxic principle. In terms of its toxicity level, lobelia is rated a major toxin. This means that ingestion of the plant can be the cause of serious consequences which may be fatal.
Yes. Cutting back lobelia plants improves their appearance and health. It also encourages the plant to produce more flowers over a longer period of time. The three types of pruning that benefit lobelia plants are removing spent flowers, pinching, and cutting back.
- Learning how to plant alyssum is easy. You can also plant sweet alyssum flowers from seed straight into the garden in mild climates. Choose a location that has full sun, although sweet alyssum plants can tolerate partial shade as well.
- Alyssum plants are small, about a few inches but they spread as much as a foot in diameter. Alyssum flowers are tiny and tightly grouped. By mid-summer, you can smell the sweet scent of alyssum. What's best about alyssum plants is that they are tiny and easy to grow.
- The ASPCA makes it very clear that petunias are not toxic to dogs, cats or other animals, but their website contains a very lengthy list of other, equally pretty plants that are mildly or lethally toxic. For that reason, it's not a good idea to allow or encourage dogs to lunch on flowers.
Annual lobelia will grow nearly anywhere. Lobelia seeds can be sown directly in the garden or indoors for later transplanting. These plants typically require an area with full sun but will tolerate partial shade. They also prefer moist, rich soil.
- Annual plants live for one growing season and then die, while perennials regrow every spring. The difference is genetic, and yet, a clever "plant gene therapy" technique can be used to change an annual into a perennial.
- Morning sun (and a little afternoon shade) is perfect. Wax begonias can tolerate more sun than other types, and the ones with bronze-colored leaves are the most sun-tolerant of all. Tuberous begonias prefer more shade and less heat, so we often see them on display in late summer. Soil: Light, rich, humusy soil.
- Are Begonias Annuals or Perennials? Are begonias a perennial plant or an annual flower? There are no perennial begonias. There are forms that make great houseplants and will grow year-round indoors, but outdoors the plants are all unable to tolerate frost.
Technically a perennial, sweet alyssum is widely treated as if it were an annual plant in the North. But it is one of the hardier annuals, able to survive light frosts that would kill tenderer plants. Its rounded clusters of flowers are fragrant.
- Most plants that we call “annuals” are actually tender perennials that can't survive winters in colder climates. We treat them like annuals, cast them on the compost heap in the fall and buy new ones the following spring. Last summer I purchased a lantana at our local garden center.
- There also are perennial Lobelias to be found. However, Lobelia erinus, about 6 inches tall and low-growing, and Lobelia cardinalis, at 36 inches tall, didn't appear to be related at all. But they certainly are. Lobelia is a genus of about 370 species of annuals, perennials (even some aquatics) and shrubs.
- Several species of plants fall under the genus Verbena. Although a few of these are annuals and need to be replanted each year, many more are perennials and come back year after year. Perennial verbena differ in size and growth form but also share many of the annuals' characteristics.
