Looking to add something to brighten your landscape this autumn? Firespike (Odontonema strictum) is a prolific fall bloomer with red tubular flowers that are very popular with hummingbirds and butterflies. It’s glossy dark green leaves make an attractive large plant that will grow quite well in dense shade to partial sunlight. In frost-free areas firespike grows as an evergreen semi-woody shrub, spreads by underground sprouts and enlarging to form a thicket. In zones 8 and 9 it usually dies back to the ground in winter and resprouts in spring, producing strikingly beautiful 9-12 inch panicles of crimson flowers beginning at the end of summer and lasting into the winter each year. Firespike is native to open, semi-forested areas of Central America. It has escaped cultivation and become established in disturbed hammocks throughout peninsular Florida, but hasn’t presented an invasive problem. Here in the Panhandle, firespike will remain a tender perennial for most locations. It can be grown on a wide range of moderately fertile, sandy soils and is quite drought tolerant. Firespike may be best utilized in the landscape in a mass planting. Plants can be spaced about 2 feet apart to fill in the area quickly. It is one of only a few flowering plants that give good, red color in a partially shaded site. The lovely flowers make firespike an excellent candidate for the cutting garden and is a “must-have” for southern butterfly and hummingbird gardens. Additional plants can be propagated from firespike by division or cuttings. However, white-tailed deer love firespike too, and will eat the leaves, so be prepared to fence it off from “Bambi”.
Florida is known for many things, however sweeping vistas of hillsides covered in the orange, red, and yellow foliage of fall is not one of them. Our long, hot summers and short, cool (not cold) winters, and lack of anything of substance resembling a season in between, precludes the fall color show our neighbors to the north enjoy. Don’t settle for synthetic Halloween decorations or faux painted leaves to add festivity to the autumn landscape design. When football season kicks off and summer blooming annuals begin to fade, it’s time to reach into the horticultural toolbox and pull out a couple fall-y Florida Friendly annual foliage species, perfect for the balmy Panhandle “autumn”: ‘Alabama Sunset’ coleus and ‘Petra’ croton.

The first plant to consider when looking for outstanding heat tolerant foliage is the common coleus (Solenostemon scuttellarioides), particularly the cultivar ‘Alabama Sunset’. As the name indicates, ‘Alabama Sunset’ offers leaves in shades of red and yellow, perfect for designing fall containers or mixing into planting beds. This popular summer annual is known for its ability to add interesting color and texture to shady areas.
Recently with the arrival of the ‘sun coleus’ series (to which ‘Alabama Sunset’ belongs), coleus is permissible in situations with greater sunlight. Coleus is incredibly easy to grow and easy to find since nearly every nursery stocks at least a few cultivars. What’s more, these plants are generally free of pests and disease problems! Even sun coleus does appreciate a little protection from the hot afternoon sun and occasional deadheading of flowers.

The second plant in the fall foliage arsenal is ‘Petra croton’ (Codiaeum variegatum ‘Petra’). Primarily known as a tropical foliage or indoor houseplant, Petra croton is criminally underused in fall landscape and container design. Petra croton sports bold magnolia-sized leaves striped with colors of yellow, red, orange, and black. A great Halloween plant to complement those front-porch Jack-O-Lanterns!
Like coleus, Petra croton is extremely easy to grow either in a container or in the ground. It should be located in either in full sun or partial shade and watered through establishment. Otherwise, this species is quite drought tolerant and can be killed with kindness if watered too frequently!
Although croton is a perennial shrub in the tropics, in Northwest Florida it may be killed by frost and best treated as an annual. Croton can be expected to reach 30-36” in height in a single season, its size and the boldly colored foliage make it a true focal point in the autumn landscape!
Appalachian-grade fall color may be unattainable in the Panhandle in the literal sense, but with these novel plant selections the autumn mood may be present even as the emerald waves hit the sugar white sand. By using annual foliage plants that possess traditional fall colors throughout their life cycle, anyone can add a splash of Autumn to their mixed containers or landscape beds. ‘Alabama Sunset’ coleus and ‘Petra’ croton are the perfect match for this time of year, pairing ease of culture with bold, seasonal color. Plant a couple today!
A few months ago I visited a property that had been renovated to clean up some limbs that were in danger of falling on the house. Pruning tree limbs that are in danger of hitting a structure is always a good idea, but it’s important to look at the impacts this practice may have on the rest of a landscape. Any time the light profile of a landscape is changed, current and future plant selection must be considered. One often seen example occurs when trees grow to full size and shade out the lush lawn that’s underneath. However, in this case, removal of limbs allowed more light to shine on some beautiful, old camellia bushes.
Camellia Planting and Care
Camellias do best in locations that receive filtered sunlight and are protected from the wind. They like acidic, well-drained soils. Trees and shrubs are generally planted 2″ to 3″ above the soil grade. (2″ to 3″ of root ball should be exposed above the soil grade when the tree/shrub is planted.) To help improve root oxygen exposure and help prevent a root rot situations, camellias can be planted slightly shallower than the previously stated recommendation. For more plant establishment guidelines, please visit: UF/IFAS Planting and Establishing Trees Guide
Scenario and Diagnosis
As mentioned above, the property in question was visited to diagnose sick camellia bushes. Upon further inspection of the property, asking about recent changes to the landscape, and inspecting the bushes, it was clear that the camellias were receiving too much sunlight. Sunlight damage was expressed by large brown sunscald spots on the yellowing leaves.

The camellias had also been pruned incorrectly. Camellias require minimal pruning. They are normally pruned to control size or promote a tree form structure if desired. Any pruning should be done before flower buds form in late summer.

Solution
The best solution in this scenario was to dig up the affected camellias and move them to a location with more shade. Sun loving shrubs were suggested as options to replace the camellia bushes. It’s important to note that Camellia sasanqua cultivars are usually more tolerant of sunlight than Camellia japonica cultivars. The recommendations were based on the Florida Friendly Landscaping principle of “Right Plant, Right Place”.

Chaste tree. The showy chaste tree makes an attractive specimen as the centerpiece of your landscape bed or in a large container on the deck. Easy-to-grow, drought resistant, and attractive to butterflies and bees, Vitex agnus-castus is a multi-stemmed small tree with fragrant, upwardly pointing lavender blooms and gray-green foliage. The chaste tree’s palmately divided leaves resemble those of the marijuana (Cannabis sativa) plant; its flowers can be mistaken for butterfly bush (Buddleia sp.); and the dry, darkened drupes can be used for seasoning, similar to black pepper, making it a conversation piece for those unfamiliar with the tree.
Vitex , with its sage-scented leaves that were once believed to have a sedative effect, has the common name “Chastetree” since Athenian women used the leaves in their beds to keep themselves chaste during the feasts of Ceres, a Roman festival held on April 12. In modern times, the tree is more often planted where beekeepers visit in order to promote excellent honey production or simply included in the landscape for the enjoyment of its showy, summer display of violet panicles.
Chaste tree is native to woodlands and dry areas of southern Europe and western Asia. It will thrive in almost any soil that has good drainage, prefers full sun or light shade, and can even tolerate moderate salt air. Vitex is a sprawling plant that grows 10-20 feet high and wide, that looks best unpruned. If pruning is desired to control the size, it should be done in the winter, since it is a deciduous tree and the blooms form on new wood. The chaste tree can take care of itself, but can be pushed to faster growth with light applications of fertilizer in spring and early summer and by mulching around the plant. There are no pests of major concern associated with this species, but, root rot can cause decline in soils that are kept too moist.
Versatile, easy-care, beautiful, native – what’s not to love about muhly grass?

How is it versatile? It makes a perfect border along a fence or structure. Plant it in a single or double row depending on available space. Use a single plant as a specimen in a smaller landscape. Muhly grass can also be planted in mass to serve as groundcover in a larger landscape.
What makes it easy-care? Since it only grows into a 3-foot-tall mound, there is no need to continually prune it as you would have to do for many landscape shrubs that serve a similar function. Plant muhly grass in areas where you only want to have plants grow to a 3-foot height, such as under windows or along a short fence. This clumping grass can be pruned in late winter to remove dead leaf blades, but it is not necessary. There are few pest and disease issues and its’ fertility needs are low. This tough plant can handle both drought and inundation with water. Perfect for a rain garden! Flowering is best in full sun, but it can take part sun as well.
What’s so beautiful about a grass? In the fall, abundant pink to pinkish/purple blooms cover the canopy of the grass and add color to the fall landscape. The wispy blooms move with the breezes and add interest with their movement. The new cultivar ‘Fast Forward’ blooms as early as August and into the winter. If pink is not your color, there is a form with white blooms known as ‘White Cloud’.
Consider adding some muhly grass to your landscape. You will love it as I do.
A very popular landscape shrub installed by both professionals and homeowners is Loropetalum or Chinese fringe. This shrub offers attractive foliage and flowers along with being evergreen.
When you visit a nursery to select this plant for your landscape, realize that there are now many selections of Loropetalum available. Learn about a few of the common selections in this recording of ‘In the Garden’, with UF/ IFAS Extension Escambia County Horticulture Agent Beth Bolles, so that you are successful at matching the appropriate plant with your landscape needs.
