Is Lobelia a sun or shade plant?
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.
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.
- Although this annual blooms dependably throughout summer and into fall, it looks better with occasional trimming. A light prune removes the spent flowers and leggy stems so the alyssum maintains its dense mounds of foliage and blooms.
- Alyssum. Alyssum will proved a carpet of tiny little flowers in your shade garden which makes it an excellent edging plant. It will tolerate a variety of soil types, but it will do best in areas with good drainage. Although all the colors will all grow in the shade, the purple varieties do better.
- Sweet Alyssum in Edible Landscaping. The low-growing habit of sweet alyssum makes it a great border plant. It is an annual, but will often self-seed. I would recommend only eating the alyssum if you grow it from seed yourself.
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).

- Water Hemlock (Cicuta maculata)
- Deadly Nightshade (Atropa belladonna)
- White Snakeroot (Ageratina altissima)
- Castor Bean (Ricinus communis)
- Rosary Pea (Abrus precatorius)
- Oleander (Nerium oleander)
- Tobacco (Nicotiana tabacum)
- Rabbits will eat many vegetables, including broccoli, beans, beet tops, carrots, lettuce and peas. They will devour many spring flowers including tulip shoots in the spring. Rabbits can also cause a great deal of damage by chewing the bark, buds and stems of woody plants.
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.
- Many flowering plants are commonly called morning glory, but the old-fashioned garden variety is botanically known as Ipomoea. The most popular varieties in this genus are native to Japan or Mexico and largely grown in North America as annual vines, but are perennial in warmer regions.
- 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.
- 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.
