(Giant Red Cardinal Flower) Similar to the plumage of a Northern Cardinal, the long-blooming flowers of this Lobelia hybrid are startlingly red. The tubular blossoms have lips that flare at their openings into petals shaped like poinsettia bracts.
When in bloom, Giant Red Cardinal Flower doubles in height. It's spectacular cardinal red flower spikes make dramatic additions to cut flower arrangements.
The clumping foliage, which forms a mound, has lance-shaped, mid-green leaves with serrated edges. Remember that young children and pets should not chew on the leaves due to their alkaloids.
Although the origin of Lobelia hybrids can be difficult to nail down, a number of sources identify Giant Red as a cross between L. cardinalis, L. siphilitica and L. fulgens. The first two plants are native to the U.S. while L. fulgens comes from Mexico.
Butterflies, honeybees and hummingbirds all are drawn to Giant Red. The great news for gardeners who enjoy developing small wildlife habitat is that this plant is easy to cultivate and grows rapidly. Although it does fine with average watering based on local conditions, it loves wet feet. So it does well in and near ponds and boggy areas in full sun.
Plant Giant Red in containers, borders, native plant gardens and seasonal flower beds. It's especially ideal for woodland gardens.

Sage Words About Wildlife: Hummingbirds Love Lobelias
Posted: Monday, August 4, 2014 Synopsis: Top-10 lists of hummingbird favorites almost always contain Salvia and Lobelia, because each genus is nectar rich and offers many species in bright reds, oranges and pinks. Hummingbirds have a weak sense of smell, but bright colors, such as those of Lobelias, lure them to flowerbeds. They are particularly devoted to the four types grown at Flowers by the Sea.

Here are some guidelines for success with this plant in your garden.

Exposure
Full Sun
This plant needs or tolerates more than six hours of intense sunlight daily. Many Salvias only thrive in wide-open locations where they receive long hours of full sun. However, full-sun species sometimes tolerate a bit of partial shade. Or a Salvia that loves partial shade may be amenable to spending part of its time in full sun.
In general, this sun/shade adaptability shows up in Salvias that do best in cooler climates when grown in full sun and thrive in hot climates when partial shade is available. So full-sun Salvias sometimes are also categorized as partial-shade plants and vice versa.
Full sun
Growing Habit
Zone(s) 6 - 10
Plant hardiness Zones defined by the U.S. Department of Agriculture tell you the minimum temperatures a plant can withstand in your garden. The USDA divides the nation into winter climate areas from coldest (Zone 1) to warmest (Zone 11).
However, it is sometimes possible to grow a Zone 6 Salvia as a perennial in Zone 5 if you provide preferential care, such as winter mulching and a location sheltered from harsh winds. In contrast, a Zone 9 Salvia may act like a perennial in Zone 10 if given a bit of shade or extra water.

36 inches tall
To create a harmonious landscape plan, it is important to consider the heights of individual plants.
Height also affects function. Short Salvias often make excellent ground covers that conserve soil moisture and discourage weeds while also brightening your yard. Medium-height Salvias, such as ones 36 inches tall, often are ideal border plants. A tall Salvia planted singly can highlight a landscape; multiple plantings can form an attractive screen.
36 inches tall
24 inches wide
By considering the width of a plant, you can determine how many to place in a row or what other plants to grow with it.
For example, a narrow, moderate-height Salvia may look good interplanted with bushier species, kind of like Mutt and Jeff.
In contrast, wide-spreading Salvias are economical for hiding lengths of wall and fence or for creating hedge-like divisions in a yard.
24 inches wide
Perennial
Plant this herbaceous species in the USDA Zones where it grows as a perennial, returning year after year.
After dying back to the ground at frost, herbaceous perennials emerge in the Spring with soft, new growth. A Salvia that is perennial in one region, may be an annual in another depending on local conditions, such as winter temperatures.
If you live in USDA Zone 5, for example, Salvias in our catalog cited as growing well in Zone 5 or lower will be perennial. Those cited as doing well in Zones 6 or higher may do well in Zone 5, but generally will act like annuals coming back from seed instead of the parent plant’s roots.

Water Needs
Average
This plant needs regular watering based on what is appropriate to your local conditions.
In some extremely hot, arid climates, this may mean daily watering in Summer. Although many drought-resistant Salvias survive on little to no watering due to local rainfall and deep roots meeting their moisture needs, others need regular doses. The size and frequency of the dose depends on your climate.
Average water
Water Loving
This plant thrives on or at least tolerates lots of water, especially when soil is well drained.
A number of Salvias hold up well in areas where rainfall is a regular occurrence. Some even tolerate boggy conditions. These are usually top-notch plants for regions of the country, such as the Southeast, where summers are soggy.

Blooming Season
Summer
This plant reaches peak bloom in Summer or flowers for much of the season.
Lots of Summer bloomers start flowering in Spring; others begin in Summer and keep up the show of color until frost.
There is a great deal of overlap in blooming seasons for Salvias.

Wildlife
Honeybees
Honeybees love this plant’s nectar. As a honeybee burrows down into a Salvia’s nectar-rich flowers to reach dinner, it accidentally gathers pollen and drops it on the stigma of that blossom or of ones on other nearby Salvias. Fertilization results in seed production.
By growing honeybee favorites, you attract these helpful pollinators to all your flowering plants and increase productivity
Honeybees
Butterflies
This plant attracts butterflies whether for nectar or as a host for their caterpillars. Some butterflies feed on a limited range of flowering plants and only lay eggs on one kind of host plant. Salvia nectar lures adult butterflies. Placing host plants, such as Milkweeds (Asclepias spp.), next to nectar plants builds butterfly habitat. In exchange, the butterflies improve fertility in your garden through pollination.
Butterflies
Deer
Unless local forage is in short supply, most deer likely will avoid this plant.
It appears that deer dislike Salvias, in general, due to their volatile oils that make the plants so fragrant and savory in cooking. However, the only completely deer-proof plants are the ones grown beyond reach.
Deer resistant
Hummingbirds
Based on our experience and reports from customers, hummingbirds (Trochilidae spp.) love this plant.
Hummingbirds exist only in the Americas where their 300-plus species are particularly fond of the nectar in brightly colored Salvias from the Western Hemisphere. However, if favorites aren’t available, they dine on the nectar of most Salvias.
Hummingbirds repay thoughtful plantings by helping to pollinate your garden
