Place them in a warm, well-lit area. The seedlings should pop up within a week or two, at which time you can begin thinning them out. After all danger of frost is gone and the plants are at least 2 to 3 inches (5-7.5 cm.) tall, transplant them to the garden—spacing about 4 to 6 inches (10-15 cm.)
Annual and perennial lobelia adapt to nearly any type of moist, well-drained soil. However, lobelia performs best in slightly acidic soil with a relatively low pH between 5.5 and 6.5.
Because of its eye-catching blue flowers, lobelia has enjoyed relative popularity amongst gardeners across the world. However, pet owners should be aware that the plant contains toxins which can be harmful to humans and animals alike. Felines can be especially badly affected if they eat Read more
Cut back the plant by half or more at the end of its bloom period. Trimming back lobelia plants keeps them from looking messy, and it may encourage another flush of blooms.
Pests and Disease Fungal problems and pests can be responsible for browning as well, especially if they feed inside the plant or directly from cells. Rust is a common external fungus on lobelia. This disease usually starts on leaf tissues, quickly covering them in orange, Read more
Lobelia in winter will die back no matter which variety you have. However, the annual Lobelia may not come back at all even if it formed seed. The annual forms tend to get weedy when temperatures get hot in summer but can be rejuvenated by Read more
Cool-season bloomers larkspur (Consolida), sweet William (Dianthus), snapdragon (Antirrhinum majus), sweet alyssum (Lobularia maritima) and lobelia (Lobelia erinus) all are reported to be deer resistant annuals. It's not surprising that deer dislike nasturtium, with its peppery flavors.
Too Much Heat. Lobelia blooms very well during cool spring weather, usually between early and late spring, but it will begin to die back during the hotter days of summer. It does not like high heat or humidity and may cease flowering during this type Read more
Growing Lobelia Plant 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.
Lobelia spicata Lam. This prairie perennial tends to be short-lived and does not have an obvious floral scent. Visitors to the small white flowers seek their nectar. Pollination is mostly carried out by hummingbirds and long-tongued bees.
Furthermore, lobelia is known to induce vomiting and can be poisonous — even fatal — in very high doses. Taking 0.6-1 gram of the leaf is said to be toxic, and 4 grams may be fatal (1, 16, 17).
Too Little Water. During warm weather, lobelia leaves and flowers can dry out. If the dehydration is too severe, the plant may die. Water your lobelia in pots consistently so the soil stays moist and never draws away from the side of the container.
Fertilize to Promote Healthy Blooms Annual and perennial lobelia varieties benefit from application of a dry, 5-10-10 or 5-10-5 fertilizer at planting time. Dig the fertilizer into the ground at a rate of about 5 pounds per 100 square feet of planting space. Repeat every Read more
These slimy pests love our gardens because we want to grow what they love to eat. Slugs and snails feed by rasping with their radula (a tongue-like organ covered with tiny teeth). When slugs or snails eat the outer layers (here on Lobelia cardinalis), weakened Read more
Planting lobelia Bedding plants should be planted out at the end of May or early June, after the fear of any frosts. If you have a greenhouse or other protected growing area, you can plant up containers and hanging baskets earlier for the plants to Read more
These plants typically require an area with full sun but will tolerate partial shade. They also prefer moist, rich soil. Start indoors about 10 to 12 weeks prior to the last frost in your region. Spread the tiny seeds just on top of the soil Read more
Lobelia is a genus of about 370 species of annuals, perennials (even some aquatics) and shrubs. They are all basically perennials, but some are treated as annuals. In their native habitat they may be found along riverbanks, wet meadows, marshes, woodlands, mountain slopes and deserts.
This fungus occurs everywhere and commonly infects senescing or damaged plant parts such as old flowers, causing a fuzzy gray mold. Spores are produced which are easily blown around. From these tissues the fungus moves into healthy stems and leaves, causing a damaging blight.
Pinching plants means taking off the tips and top two leaves of tender, young growth. It encourages bushy growth and better flowering. Trimming back lobelia plants keeps them from looking messy, and it may encourage another flush of blooms.
Lobelia is considered a potentially toxic herb. It can cause serious side effects, such as profuse sweating, nausea, vomiting, diarrhea, tremors, rapid heartbeat, mental confusion, convulsions, hypothermia, coma, and possibly even death.
Lobelias don't care for heat or drought; their transport tissues aren't designed to function under extreme heat so leaves often brown and curl up from the outer edge inward when it's too hot. Lobelia with brown leaves but healthy stems may have been exposed to Read more
Should I Prune My 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.
Lobelia erinus is the annual variety of the plant and comes in many species. It is not hardy in cold temperatures and will not survive being frozen. The annual forms tend to get weedy when temperatures get hot in summer but can be rejuvenated by Read more
Lobelia erinus (edging lobelia, garden lobelia or trailing lobelia) is a species of flowering plant in the bellflower family Campanulaceae, native to southern Africa.
Edible Uses: The buds and young plants are cooked and used as a famine food[177, 179]. Caution is advised because they contain a toxic alkaloid.
Once established, the lobelia plant requires little maintenance. Lobelia should delight your garden with beautiful blooms about mid-summer, continuing on up to the first frost. Although not necessary, you can deadhead lobelia plants to maintain a neat appearance.
Lobelia erinus is the annual variety of the plant and comes in many species. It is not hardy in cold temperatures and will not survive being frozen. The Lobelia x speciosa varieties are perennials. These are hardy to 5 to 14 degrees Fahrenheit (-15 to Read more
Too Little Water During warm weather, lobelia leaves and flowers can dry out. If the dehydration is too severe, the plant may die. Water your lobelia in pots consistently so the soil stays moist and never draws away from the side of the container.
Once established, the lobelia plant requires little maintenance. During hot, dry periods, care of lobelia requires that the plant should receive frequent watering, however, especially those in containers. A general-purpose liquid fertilizer can be given once a month or every four to six weeks, if Read more
Highly attractive: bees including yellow-faced bees, sweat bees, small carpenter bees, and bumble bees.
Water and Nutrients Blue lobelia grows best in moist soil, so regular watering results in the healthiest plants and attractive flowers. The plant needs watering about twice a week, especially during dry periods, so the top 6 inches of soil remain moist at all times.
Perennial lobelia Lobelia cardinalis can be grown in sun or, preferably, partial shade. It needs a good, fertile soil that remains moist during summer, and doesn't dry out. Lobelia tupa needs a sheltered position in full sun and a good, fertile, well-drained soil.
Growing Lobelia in Containers These petite pink, white, or blue flowers create a dramatic impact in planters. The profusion of blooms makes growing lobelia in a pot an excellent choice. These plants require consistent moisture, but they do not grow well when overwatered or when Read more

Physical description. Lobelia species are annual or perennial herbs or undershrubs, rarely shrubby, although the “tree” lobelias found at high elevations on the mountains of tropical Africa are remarkable arborescent forms.
However, overwatering your lobelia in an attempt to compensate for hot weather or a dying or unhealthy-looking plant can sometimes provide the right conditions for root rot, a cosmopolitan group of fungi that are widespread and attack plant roots in a variety of habitats.
Lobelia is often touted for its use in such respiratory conditions as asthma, bronchitis, and pneumonia. This is because the herb is said to act as an expectorant, helping to thin mucus (phlegm), cause a more productive cough, and help you to breathe better.
Lobelia. Add lobelias to shade gardens for rich, true blues. Annual lobelia is a cool-season plant that can tolerate most light conditions, including shade.
Lobelia (Lobelia cardinalis), which is of the family Campanulaceae and is also known as Indian pink and cardinal flower, is one of many plants that are poisonous to dogs when ingested. Vet bills can sneak up on you.
Care of Lobelia Plants Once established, the lobelia plant requires little maintenance. During hot, dry periods, care of lobelia requires that the plant should receive frequent watering, however, especially those in containers.
