Aechmea weilbachii forma viridisepala

The showy inflorescence of Aechmea weilbachii forma viridisepala combines green, orange, red and purple into a long-lasting display.  The flower spike appears in late fall and lasts for several months.

The spike tends to arch slightly and then curves upward.  Unlike many Aechmeas, the foliage on this one is soft and spineless, almost grass-like.  Individual leaves can be two feet long spreading out in all directions.  Plants usually grow about one and a half foot in height.

Aechmea weilbachii grows well in shade or filtered sun, and the leaves will be lighter green in higher light. The foliage makes it appear like a delicate tropical plant, but it will tolerate temperatures in the low 20°F range.

There are two other forms of this species that have a completely different appearance. See also: Aechmea weilbachii forma pendula

Billbergia Hoelscheriana

Billbergia 'Hoelscheriana' is commonly sold in Florida as B. saundersii. In reality, it is a hybrid; B. nutans x saundersii. It can be distingued from the true saundersii by the blue tips on the sepals and the blue-marginated petals. This is a small, hardy bromeliad that is effectively used in mass plantings.  In late fall the plants all come into bloom at the same time, creating a spectacular display.  Like many Billbergias, the flowers don't last long, but in large clumps of this cultivar, there will often be a second flowering about a month later.

Individual plants only get about 8-12 inches tall, with an upright growth habit.  In shaded areas they will have green leaves with white spots.  In sunnier areas, the foliage will take on a pinkish or reddish hue.

This cultivar is reportedly hardy to at least 20°F.

Aechmea apocalyptica

Aechmea apocalyptica is a fall-blooming species with showy orange spikes and gray-lavender flowers.  Plants get about a foot and a half tall and two foot wide.  They do well in shade or filtered sun.  This species is reportedly hardy to at least 20°F.

Malvaviscus arboreus (Sleeping Hibiscus)

Malvaviscus arboreus var. mexicanus is a fall and winter-blooming relative of Hibiscus.  The bright red flowers are pendulous and last for several days.  The petals do not flare back like Hibiscus, but remain swirled around the pistil.  This gives the impression that the flowers never open, and hence the common name of Sleeping Hibiscus.  It is also sometimes known as Turk's Cap or Lipstick Hibiscus.  There is a pale pink color-form that is not as showy.

Malvaviscus arboreus is a large woody shrub growing to eight foot tall by six foot wide.  It is native to Mexico and is recommended for USDA Zones 9-12.  It flowers best in full sun, but will grow quite well in shady areas.  It is drought-tolerant once established.

There is a nectary at the base of the flower and you can taste the sweetness by plucking off the bloom and sucking on the end of it. The petals themselves are also edible, but lacking in flavor.

There are two distinct varieties and many online resources confuse the two.  Variety mexicanus is the one pictured and described here, and is the one most commonly grown in Florida.  Variety drummondii (most commonly grown in Texas) apparently has broader fuzzy leaves, more erect flowers, red fruits, enjoys moist, part-shade conditions, can become almost vine-like, blooms in summer, and is apparently more cold-hardy.  One online nursery is growing them as a perennial in Zone 6B!
It's strange that these two plants are classified as varieties and not separate species, given their completely different habitats and form.  If you're shopping for this plant, make sure you know which one you're getting!

Hibiscus radiatus

The red-velvet flowers of Hibiscus radiatus make this species a must-have among the fall and winter blooming varieties of Hibiscus.  Like some other short-day bloomers in the genus, this one has long stems that arch over and grow horizontally as the season progresses.  Left on its own, this plant will form a wide mound of flowers four foot tall and eight foot or more wide.  It's not unattractive, but takes up a lot of space in the garden.

To keep the plant a more manageable size, clip the growing tips repeatedly throughout the summer.  This will force increased branching and a more bushy, compact habit.

Hibiscus radiatus is classified as a short-lived perennial for USDA Zones 10-11, but it is successfully grown as an annual elsewhere.  In late fall the palmate leaves will often turn a red-gold color, providing additional interest.

Small branches and the underside of the leaf petioles are covered with small prickles that reportedly make this plant deer-resistant.

This species is supposedly also known as Monarch Rosemallow or Ruby Hibiscus. The leaves are edible, and they have a pleasant lemony flavor, making them a nice addition to salads. Only use the flat part of the leaf though--the petiole has those annoying prickles!

Hibiscus sabdariffa (Roselle)

Roselle, Sorrel, Jelly Okra, Florida Cranberry, whatever you call it, Hibiscus sabdariffa is another of the fall and winter blooming species of Hibiscus.  In addition to the attractive pale yellow flowers with maroon centers, this one produces an edible fruit.  Well, technically, it's an enlarged calyx, but it can be used like a fruit to make tea, cold drinks, wine, syrup, jams, relishes, added to salads, or simply eaten fresh.
The calyces turn bright red as they enlarge, growing to two inches in length and rivaling the blooms in their colorful display.  Any surplus of calyces can be frozen, sun-dried, or dehydrated for later use.  They have a tart flavor similar to Cranberry.  Young leaves may be eaten raw in salads or cooked as a green vegetable.
This species has a shrubby habit, growing 6-8 foot in height.

Hibiscus sabdariffa is a native of the region from India to Malaysia but is now grown in tropical regions world-wide.  It is recommended for USDA Zones 8-11 and is usually grown as an annual plant, going from seed to maturity in a single year.  In Zones 10 and 11 it can be grown as a short-lived perennial.  One subspecies of this plant is grown primarily for the commercial fiber obtained from the stems.

In traditional medicines, Roselle is used to treat high blood pressure and hangover.  It has also been found to have anti-bacterial properties.

Hibiscus acetosella

Hibiscus acetosella is one of the fall and winter-blooming species of Hibiscus.  This one has dark, maroon-colored leaves to provide spring and summer interest as well.  In the fall, mauve-pink flowers appear.  Like most Hibiscus, each flower lasts only a day, but every day new blooms open.

The plant is fast-growing to 6-8 feet, and has a narrow, lanky growth habit.  If left unpruned, the tall plants usually start to bend over and grow horizontally by late fall and early winter.  To keep a more shrubby, erect habit it is necessary to prune the tip growth several times during the course of the summer.  This will force a more branching habit and sturdier main stem.

Natural unpruned form

Hibiscus acetosella is classified as a perennial shrub for USDA Zones 10-11.  Elsewhere, it can be grown as an annual plant, and they will reseed freely in the garden where the growing season continues into late fall.  Bloom continues through the winter until frost, or in tropical climates, until the day length increases and bud formation stops.
This species is native to Africa, and has many common names, including False Roselle, African Rosemallow, and Red-leaf Hibiscus.
The leaves are edible, with a slightly tart flavor, and can be added to salads or stir-fries for color.  Flowers can be made into a colorful tea, but have little flavor of their own and usually require the addition of  sweeteners and lemon or lime.

Brugmansia (Angel Trumpet)

Few garden plants have blooms to rival the foot-long trumpets of Brugmansia.  The huge, pendulous blooms are not only an eye-catcher, but they are also fragrant at night.  The plants grow quickly into a large shrub or small tree, up to 15 feet or more.  Flowers appear in masses every few weeks from spring through fall, between periods of rest.  There are countless hybrids and color variations, and flowers may be single, double, or triple-petaled.  Some cultivars have blooms up to 20 inches long.

Flowers of some varieties change color as the blooms mature, and there may also be some color shift from the heat of the summer to cooler fall days.

Brugmansias are native to Central and South America, and there are several closely related species that all share similar characteristics.  It is recommended for USDA Zones 9-12, surviving as a perennial in Zones 8B to 9B.  In the colder areas, Brugmansia will freeze to the ground during a hard winter, but growth returns so fast that in a few months you will be unable to tell there was any damage.  In cold climates, Brugmansia can be grown in containers.  Here are some flowering in 10 inch pots.

Brugmansias bloom best in full sun but the large leaves transpire moisture quickly, so plants in the warmer zones often benefit from some afternoon shade.
All parts of the plant are narcotic and poisonous.  The name Angel Trumpet refers to both the shape of the bloom and the hallucinogenic effects from ingesting the plant.
