A Wildflower Among Weeds

A Wildflower Among Weeds

The change in North Florida temperatures from cooler to warmer is making many winter weeds more noticeable as they begin to flower and form seed. Not all of these plants should be considered for mowing or hand pulling. There are several wildflowers that grow in landscape beds and thinning areas of lawns and can be enjoyed before consistent heat returns.

One very delicate wildflower that is growing now is the Toadflax, Linaria canadensis. The leaves are very small and grow low on the ground. Thin flower stalks grow several inches and are topped with light purple flowers. Although toadflax pops up in beds and lawns don’t be so quick to pull it out. This wildflower is a host to the Buckeye butterfly, one of our earlier visitors to gardens. If you look closely you may even see the tiny black, spiny caterpillar eating toadflax leaves. Visit the UF publication on the Buckeye butterfly to learn more.

Plant Cupheas for Summer Flowers, Hummingbirds, and More

Cupheas are perennials that produce bright orange, red, yellow or purple flowers all summer and fall.  Some species are called cigar plants due to their tubular, cigar shaped flowers tipped in red or yellow (like a lit cigar). Others are sometimes called firecracker plants because their cylindrical flowers are bright red or orange (looking like a firecracker). By any name, their nectar-filled, tubular flowers are widely known for attracting large numbers of hummingbirds, butterflies and bees. In addition, young stems of some species are reddish, further adding color and contrast to the usually narrow, lance-shaped green foliage.

 

As a group, cupheas grow best in full to part sun (the brighter, the better) and well-drained, moderately fertile soil. Cupheas are drought tolerant once established, but grow faster and larger with regular moisture and occasional fertilization. Their origins in warm climates allow them to thrive in heat, but likewise make some species sensitive to cold winters. Those that are frost tender along the Gulf Coast are best placed in a sheltered location in the garden. Cupheas are pest and disease resistant and are not invasive in Florida. They are not truly deer resistant, yet reports suggest cupheas are not favored by deer.

Cupheas are great summer performers in bright, hot and dry locations. Flowering begins in summer and continues through fall until short days and cool weather reduce flowering or frosts cause dieback. Along the Gulf Coast, cool winter weather slows them down, so re-growth doesn’t occur until mid to late spring, and flowering usually doesn’t begin until days and nights are warm. Growth and appearance of many cupheas are improved if plants are pruned or cut to the ground in late winter.

Over 200 species of Cuphea are native to Mexico and the warm-temperate and tropical Americas. Of these and their hybrids, the cupheas listed below are great summer-flowering perennials for the northern Gulf Coast.

Cigar Plant (Cuphea ignea)

This fine-textured plant produces red to orange tubular flowers about an inch long. This cigar plant is hardy to about 20°F. It grows about 2 feet tall and 3 feet wide along the Gulf Coast, though it would be a larger, evergreen shrub in warmer climates. This cuphea tends to have lanky growth, so occasional summer pruning will stimulate branching which results in more dense growth.

 

Cigar Plant or Candy Corn Plant (Cuphea micropetala)

Flowers are 1.5 inches long, emerge pale yellow and gradually turn orange from the base upwards, offering a colorful, two-tone effect. Foliage is hardy to 25-30°F and this cigar plant is root hardy to at least 15°F. Stems should be cut back to ground level in late winter to keep the plant tidy. Clumps spread slowly outward by rhizomes, and the plant will reach 3 feet tall and wide along the Gulf Coast.

Orange Cigar Plant or Schumann’s Cuphea (Cuphea schumannii)

This sprawling, floriferous cigar plant prefers moist, well-drained soil to thrive. Barrel-shaped, 1- to 1½-inch blooms are orange and yellow and sometimes have small purple petals at the tips. Flowers cover the branch terminals in the heat of summer and into fall. This plant is hardy in Zones 8 to 9 (at least down to the mid 20s°F). Unlike many other cupheas, leaves of orange cigar plant are oval- to heart-shaped. Stems grow 2 to 3 feet tall and readily flop or fall over. Plan to give orange cigar plant lots of room to sprawl through the garden!

‘David Verity’ Large Firecracker Plant (Cuphea ignea × micropetala ‘David Verity’)

This floriferous hybrid produces flowers that are dark orange with a short yellow-orange flared tip and purple filamentts. Well-adapted to the Gulf Coast, this plant is foliage hardy down to 25-30°F and root hardy to at least 15°F. In Zone 9 this plant will grow as an evergreen shrub up to 4 to 5 feet tall and wide, but it will be smaller in areas where frost or freezes occur. This selection is believed to be a hybrid between Cuphea ignea and C. micropetala that was given in the mid 1970s to David Verity, then the manager of the UCLA Mildred Mathias Botanic Garden. It was subsequently named for him when later brought into commercial production.

 

‘Vermillionaire®’ Large Firecracker Plant (Cuphea ‘Vermillionaire®’)

This new hybrid appears to be a superior cuphea because it grows as a naturally compact plant that produces more flowers than other selections. ‘Vermillionaire®’ grows about 24 inches or more tall and wide with a compact, mounding habit. Orange tubular flowers are produced continuously until late fall. This cuphea is too new to know the full extent of its hardiness, but it is expected to be a perennial in Zones 8 and higher.

 

Mexican Heather (Cuphea hyssopifolia)

Unlike the previous cupheas, this plant has small purple flowers, and some selections sport white flowers. Another difference is Mexican heather’s finely textured, bright green leaves. Gulf Coast Zone 8 plants are usually killed to the ground in winter, often recovering by summer but resulting in a compact plant growing less than 24 inches tall and wide. In Zones 9 and higher, Mexican heather is a larger-growing semi-evergreen tropical shrub. Reported pests are leaf-chewing beetles (Altica and Colaspis spp.) and the twig-dwelling lesser snow scale (Pinnaspis strachani). Mexican heather works well for edging beds or sidewalks, helping to define and soften pathways. Cultivars include Allyson, Lavender Lace, Purple Nurple™ and the white-flowered Monga (Itsy Bitsy° White) and ‘White Whispers’.

Bat-Faced Cuphea

Bat Face Cuphea (Cuphea llavea)

Each 1-inch flower consists of a purple tube lipped with two red, upright lobes. By viewing the flower with its tip facing you, it takes only a little imagination to see the two red lobes resemble large “ears” above the purple “face” of a bat, hence the name. Along the Gulf Coast, bat face cuphea grows mound-shaped 8 to 24 inches tall and wide, depending upon the selection. It is very heat and drought tolerant but requires better drainage than the other cupheas. Bat face cuphea is evergreen down to the upper 20s°F and root hardy into the lower 20s°F. Improved forms of bat face cuphea include the cultivars, Flamenco Samba, Georgia Scarlet, Mellow Yellow, Miss Priss, Tiny Mice®, Sriracha™ Pink, Sriracha™ Violet, Torpedo, Vienco° Lavender and Vienco° Red.

Tired of Turf? Try Groundcover Alternatives Instead!

If you’re like me, growing turfgrass is often more of a hassle than anything else.  Regardless of the species you plant, none tolerates shade well and it can seem like there is a never-ending list of chores and expenses that accompany lawn grass:  mowing (at least one a week during the summer), fertilizing, and constantly battling weeds, disease and bugs.  Wouldn’t it be nice if there were an acceptable alternative, at least for the parts of the lawn that get a little less foot traffic or are shady?  Turns out there is!  Enter the wonderful world of perennial groundcovers!

Perennial groundcovers are just that, plants that are either evergreen or herbaceous (killed to the ground by frost, similar to turfgrass) and are aggressive enough to cover the ground quickly.  Once established, these solid masses of stylish, easy to grow plants serve many of the same functions traditional turf lawns do without all the hassle: choke out weeds, provide pleasing aesthetics, reduce erosion and runoff, and provide a habitat for beneficial insects and wildlife.

The two most common turfgrass replacements found in Northwest Florida are Ornamental Perennial Peanut (Arachis glabra) and Asiatic Jasmine (Trachelospermum asiaticum); though a native species of Mimosa (Mimosa strigillosa) is gaining popularity also.  All of these plants are outstanding groundcovers but each fills a specific niche in the landscape.

Perennial Peanut Lawn

Perennial Peanut is a beautiful, aggressive groundcover that spreads through underground rhizomes and possesses showy yellow flowers throughout the year; the show stops only in the coldest winters when the plant is burned back to the ground by frost.  It thrives in sunny, well-drained soils, needs no supplemental irrigation once established and because it is a legume, requires little to no supplemental fertilizer.  It even thrives in coastal areas that are subject to periodic salt spray!  If Perennial Peanut ever begins to look a little unkempt, a quick mowing at 3-4” will enhance its appearance.

Asiatic Jasmine

 

Asiatic Jasmine is a superb, vining groundcover option for areas that receive partial to full shade, though it will tolerate full sun.  This evergreen plant sports glossy dark green foliage and is extremely aggressive (lending itself to very rapid establishment).  Though not as vigorous a climber as its more well-known cousin Confederate Jasmine (Trachelospermum jasminoides), Asiatic Jasmine will eventually begin to slowly climb trees and other structures once it is fully established; this habit is easily controlled with infrequent pruning.  Do not look for flowers on this vining groundcover however, as it does not initiate the bloom cycle unless allowed to climb.

Sunshine Mimosa

For those that prefer an all-native landscape, Sunshine Mimosa (Mimosa strigillosa), also known as Sensitive Plant, is a fantastic groundcover option for full-sun situations.  This herbaceous perennial is very striking in flower, sending up bright pink, fiber-optic like blooms about 6” above the foliage all summer long!  Sunshine Mimosa, like Perennial Peanut, is a legume so fertility needs are very low. It is also exceptionally drought tolerant and thrives in the deepest sands.  If there is a dry problem spot in your lawn that receives full sun, you can’t go wrong with this one!

As a rule, the method of establishing groundcovers as turfgrass replacements takes a bit longer than with laying sod, which allows for an “instant” lawn.  With groundcovers, sprigging containerized plants is most common as this is how the majority of these species are grown in production nurseries.  This process involves planting the containerized sprigs on a grid in the planting area no more than 12” apart.  The sprigs may be planted closer together (8”-10”) if more rapid establishment is desired.

During the establishment phase, weed control is critical to ensure proper development of the groundcover.  The first step to reduce competitive weeds is to clean the site thoroughly before planting with a non-selective herbicide such as Glyphosate.  After planting, grassy weeds may be treated with one of the selective herbicides Fusilade, Poast, Select, or Prism.  Unfortunately, there are not any chemical treatments for broadleaf weed control in ornamental groundcovers but these can be managed by mowing or hand pulling and will eventually be choked out by the groundcover.

If you are tired of the turfgrass life and want some relief, try an ornamental groundcover instead!  They are low-maintenance, cost effective, and very attractive!  Happy gardening and as always, contact your local UF/IFAS County Extension Office for more information about this topic!

Drama in the Garden with Amazon Dianthus Series

We may shy away from drama in our lives but drama in the garden is always welcome. One plant series that will be a prominent feature in any garden bed is the Amazon Dianthus series.

Although we normally consider Fall the time to plant dianthus, the Amazon Series developed by PanAmerican Seed company can be planted in Spring for blooms that extend into Summer. This is the combination of two dianthus and the results are plants with striking colors and longer blooming cycles.

The Amazon series comes in a few bright colors including Amazon Neon Cherry, Amazon Neon Pink, and Amazon Rose Magic. Flowers are held on stems about 1.5-2′ tall and foliage is an attractive dark green. Plants are generally low maintenance but be sure to deadhead flowers as they fade. Plants will need rich, well drained soil and full sun.
