Can you cut back trailing lobelia?
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.
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.
- Pansies perform best in cooler weather, and are therefore usually planted in spring or fall. They like rich, well-drained soil high in organic matter, and full sun or partial shade. (Shade is especially beneficial south of Zone 7 where the hot afternoon sun will shut down flower production.)
- When the plants have three leaves, you can plant them outside. It's best to buy transplants and plant them in light, well-drained soil in full sun after the last spring frost. (See your local frost dates.) Petunias can grow in partial shade, but they will have fewer flowers.
- 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.
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.
- According to the Washington State University Extension, the seeds of Southern magnolia are poisonous if eaten by humans (the wild birds and the squirrels do not seem to be adversely affected). Nor, according to the ASPCA, are they poisonous to pets (either cats or dogs).
- Gardenias are generally considered to be a non-toxic plant to most animals, but there are some exceptions. Horses, guinea pigs, cats and dogs should not be allowed to nibble on any part of these plants. Most other pets would not be affected by this plant.
- Toxicity. Marigold flowers and leaves are considered safe to eat by humans and are commonly used as culinary herbs. According to the American Society for the Prevention of Cruelty to Animals, pot marigolds are also not considered toxic to puppies when ingested or touched.
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.
- Plantaginaceae is a fairly large family that ranges throughout the world. It includes herbaceous annuals and perennials, and shrubs.
- Snapdragons (Antirrhinum majus) are short-lived tender perennials, which are often grown as annuals. If they survive through the winter, they will bloom every year, but they rarely survive year to year.
- Dianthus flowers (Dianthus spp.) are also called “pinks.” They belong to a family of plants which includes carnations and are characterized by the spicy fragrance the blooms emit. Dianthus plants may be found as a hardy annual, biennial or perennial and most often used in borders or potted displays.
