Firespike

Firespike

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.  Its 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 re-sprouts 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.

Red flower with hummingbirdFirespike 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”.

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.  Much more of them are being seen since the Florida Department of Transportation has recognized the tree as a desirable median planting.  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.

Year ‘Round Interest with Juliet™ Cleyera

Year ‘Round Interest with Juliet™ Cleyera

Plants with variegated foliage are very popular landscape selections.  As flowers fade on other plants, the colors of variegated foliage continue to add interest through multiple seasons.

A very adaptable shrub that has been around for a long time, now has a selection with beautiful variegated foliage.  Juliet™ cleyera offers green and white evergreen foliage that can brighten up a garden year around.  New foliage adds additional interest with a maroon tinge.

Like other selections of Cleyera, Juliet™ needs to be matched to an appropriate spot to accommodate its mature size.  Shrubs will reach about 8 feet in height with a spread of about 5 feet.  Plants may look best when left to grow in a more natural form with light selective pruning.  This shrub is probably not suited for planting in front of home windows but used as a specimen or as a nice screen plant.

Once established, cleyera is a low maintenance plant and is adapted to grow well without routine irrigation.  My home landscape has very well drained soil and I have not needed to apply supplemental irrigation to two cleyera shrubs in over 20 years.  Consider a spot that receives full sun or partial shade for your plants.

An added advantage of cleyera shrubs in general is that bees are attracted to the flowers so it makes an additional nectar source for pollinators in the spring.

Ornamental Grass Pruning – A Winter Task

Ornamental Grass Pruning – A Winter Task

The term “ornamental grass” is a catch-all phrase used to describe grasses and “grass-like” plants.  Individual species are adapted to a wide variety of landscape sites (i.e., wet or dry, sun or shade, hot or cold climates, and varied salt tolerance). Growth habits range from low ground covers to intermediate shrub-like plants to very tall hedge-like plants. Ornamental grasses are very dynamic; the size, shape, texture, and color of grass changes with every season.

Deciduous Ornamental Grass

Grasses with foliage that dies in the winter and remains dormant until the weather warms in the spring are considered deciduous.  The winter character of deciduous ornamental grasses adds tremendous interest to the winter garden when contrasted with evergreen plants or structures such as walls or fences.  The dried foliage of deciduous grasses creates sound as it expands and contracts in response to changes in temperature or moisture, while interaction with wind creates movement in the garden. For these reasons, pruning of the dead foliage and inflorescences is not recommended at the time of the first frost.

Pruning of ornamental grasses should be done in late winter or early spring, just prior to new shoot growth.  In Northwest Florida, gardeners should target the end of February to prune ornamental grasses.  For deciduous grasses, such as Japanese silver grass (Miscanthus sinensis), the old foliage may be completely removed within inches of the soil. Be cautious to not remove the growth point by leaving the grass clump at least 4 inches high.  For evergreen grasses, such as muhly grass (Muhlenbergia capillaris), the ragged leaves can be removed to neaten the appearance of the plant without shortening all the way to the ground. So, depending on the damaged portions, the remaining grass clump can be 6-18 inches high after pruning.  Grasses recover quickly from a heavier pruning.  Within a few months the plant will have completely regrown.  If desired, old flower stalks and seed heads may be removed any time they no longer have a neat appearance.  For more information on ornamental grass species and growing tips, please visit the EDIS Publication: Considerations for Selection and Use of Ornamental Grasses.

Upgrade Your Gardening with Quality Pruners!

Upgrade Your Gardening with Quality Pruners!

There is an old saying that rings true in pretty much any situation – “You get what you pay for.”  Gardening tools, especially pruners, are no exception.  We’ve all been there, fumbling around with a pair of rusty, dull, cheap garden pruners that just barely get the job done.  Unfortunately, they can also do considerable harm to the plants you’re trying to improve, as anything short of a nice, sharp, clean cut introduces the potential for insect/disease infestation and will produce a wound that takes much longer to heal, if it ever heals properly at all.  You wouldn’t want your doctor to start hacking away at you with a dirty, second-rate scalpel.  Don’t subject your plants to the same treatment!  While I’m not advocating blowing hundreds or thousands of dollars outfitting your garden tool shed with top of the line everything, investing in a pair of quality bypass hand pruners will pay dividends many years into the future and make your gardening experience much more enjoyable!

Found in three designs, from old-fashioned anvil pruners that smush and smash their way to a cut, to ratcheting pruners that make short work of larger branches but tend to be cumbersome and complicated, to bypass pruners that produce clean cuts in a scissor-like manner, hand pruners accomplish many tasks in the landscape.  From cutting small limbs, to harvesting vegetables, to deadheading annual flowers and everything in between, there isn’t a more frequently used, versatile tool.  Therefore, it makes sense to buy a quality pair that will perform excellently, still be snipping long after your pruning days are over (if you take care of them), and that are comfortable enough you will enjoy using them.  When shopping for your pair of “forever” pruners, there are a few things to look for.

  • Only use bypass style pruners. Your plants will appreciate it.
  • Look for heavy duty pruners with frames made from quality aluminum or stainless steel; they won’t rust and won’t easily bend or break.
  • Buy pruners with replaceable parts. This is especially key because springs eventually rust and gum up and blades break and will eventually lose their ability to hold an edge over time (though you can and should resharpen them).

There are two commonly found brands that fit all three above criteria, albeit at different price points.  For a high quality “budget” blade, various models from Corona do an excellent job for the money ($20-30) and won’t hurt your feelings too badly if you happen to lose a pair.  Should you decide to splurge a little, Felco makes sharp, indestructible pruners, in multiple models around $50 to fit all size hands.  Felco has become the horticulture industry standard and you’d be hard pressed to find a nursery owner or landscaper that didn’t own a pair (or two).

Regardless of which brand you buy (and there are many more than the two above listed) a pair of well-made pruners, if taken care of, should last a lifetime and make your gardening experience much more enjoyable for you and your plants!  If you have any questions about gardening tools or equipment or any other horticulture or agronomic topic, feel free to contact your local UF/IFAS Extension Office.  Happy Gardening!
