Spice Up Your Salad with Unusual Leafy Greens

Spice Up Your Salad with Unusual Leafy Greens

Many Americans have a remarkably unrefined taste in salads; my brother has long counted himself in this group.    Dice up some crunchy Iceberg type lettuce, splash on a dollop of ranch dressing, maybe chop a leaf of romaine up if you’re feeling frisky and call it a salad, this is the way we’ve been trained to eat.  I’m here, a voice in the supermarket produce aisle wilderness calling, to tell you it’s time to open up your palate, look beyond lettuce, live a little, and add some spice to your life and salad bowl with three of my favorite easy to grow leafy greens:  Mizuna, Frilly Mustard, and Italian Dandelion.

Before we get into species specifics, let’s cover a couple of reasons you should grow them at home!  Growing your own flavor-packed greens has many benefits.  First, leaves from these plants can be difficult to find anywhere but specialty health food stores or high-end supermarkets.  Growing your own ensures a consistent supply, especially if one utilizes the “cut and come again” harvesting method (just remove the leaves and stems you need that day, leave the crown intact and allow the plant to regrow for next week’s harvest).  Second, you do not have to worry about the too common food safety recalls and other health scares involving “leafies”.  If you follow standard safety practices (clean irrigation water, wash picked leaves and store properly, etc.), you’ll be eating scrumptious salads when everyone else is begrudgingly trashing entire bags of recalled store-bought greens.  Finally, each of these species double as gorgeous accent plants in

raised beds or containers.  I love plants that do heavy lifting as both eye-catching ornamentals and delicious edibles!

Mizuna is a little known member of the mustard family that is quickly becoming one of my favorite leafy greens!  It faces no major pest or disease problems in the garden and it is extremely tolerant of the cold weather Floridians periodically face through the winter, laughing off frost.  Mizuna possesses lovely, deeply cut, pale green, fringy leaves complete with crispy white stems, all of which are edible – no need to separate stems when processing to eat!  This lovely little Asian green has a mild peppery taste (think a toned-down Arugula) and adds perfect flavor and texture to any salad!

Many Southerners are well acquainted with traditional Mustard greens and their preparation (more than a little bacon and salt) but may not be aware of newer Mustard cultivars that give the species a bit of refinement and make it a salad celebrity!  This winter, I’m growing a cultivar of Mustard called ‘Scarlet Frills’ (aptly named with finely serrated burgundy-red leaves) and really enjoy its peppery horseradish taste as a foil to the mildly sweet taste of traditional salad greens like lettuce and spinach.  Mustards are extremely cold tolerant and slow to bolt, making it a mainstay in the salad garden all winter long; you really get your money’s worth from a few Mustard plants!  However, even if this leafy green wasn’t delicious, it would be worth growing.  The “fancier” Mustard cultivars are highly ornamental and deserve a spot in any cool season container garden.

Finally, the one that turns up the most noses when I mention growing and eating it, Italian Dandelion (Cichorium intybus)!  I’m not advocating foraging in your turfgrass to find dinner, in fact, Italian Dandelion is not a true dandelion (it’s actually a chicory).  However, it does share a number of features with its weedy cousin, including leaves that are similar in appearance and a vigorous taproot.  That’s where the comparisons stop though, as Italian dandelion is a superior garden plant, more upright growing, much larger, and deeper green (some varieties including the one I grow ‘Italiko Red’ have red veined leaves) than its wild cousin.  Unlike Mizuna and some of the milder mustards, Italian Dandelion is a bit of an acquired taste.  It imparts a strong bitter flavor that may be cut with milder greens in a salad or cooked down to reduce bitterness. Either way you try it, put Italian Dandelion on your cool season garden next year!

Mizuna, Frilly Mustard, and Italian Dandelion all require similar growing conditions.  In Florida, leafy greens are cool season vegetables, growing through the fall, winter and spring months.  Seeds should be sown in late September and can be stagger-sown (plantings every couple of weeks) to ensure a steady supply through spring.  As a rule, they prefer rich, well-drained soil high in organic matter.  These soil conditions are achievable with either quality commercial potting mixes or homemade concoctions of compost and pine bark. The beds or containers you fill with the aforementioned soil should be sited near a good water source (plants that aren’t convenient to water get neglected, trust me) in an area that gets 6-8 hours of full sunlight.  I like to topdress at planting (if using transplants) or after germination (if using seed) with a good general purpose, slow-release fertilizer, many formulations and brands that work are widely available for purchase.  Finally, be sure to purchase seed from a quality source.  Online purveyors Johnny’s Selected Seeds, Baker Creek Heirloom Seeds, and Sow True Seeds are good places to start, though the options are nearly endless!

Next year, when planning your cool season garden, remember to add a little spice with these three leafy greens, Mizuna, Frilly Mustard, and Italian Dandelion!  For more information about cool season gardening and other topics, consult your local UF/IFAS Extension Office.

Fatsia japonica Provides Gorgeous Winter Blooms

Fatsia japonica Provides Gorgeous Winter Blooms

Fatsia japonica, common name Japanese aralia, provides tropical texture to your landscape.  That coarse texture is attributed to its large (nearly a foot wide) leaves that are deeply lobed (maple leaf shaped).  This shade-loving plant performs well in moist (not soggy) locations.  Upright stems originate near ground level usually near the base of older stems.  The stems grow to about eight feet tall before bending toward the ground under their own weight.

Even though the foliage of this species is enough to make you want it in your own garden, you will absolutely fall in love with its blooms.  Upright clusters of showy, creamy white flowers begin to appear in fall.  These little snowballs provide wonderful color to your garden.  The shiny, black fruits appear in winter and are prominent for several weeks.  The fruit are know to attract birds to the landscape.

Fatsia japonica thrives in the shade in slightly acidic, nutrient-rich, moist soil.  Older stems become leggy and can be cut back to encourage branching.  In the right place, Fatsia japonica is low-maintenance and not typically bothered by pests.  It is also known to perform well in coastal landscapes.  It fits well in entryways, in containers, or in mass plantings spaced three feet apart.

 

Create Your Own Fall Color with Annual Foliage Plants

Create Your Own Fall Color with Annual Foliage Plants

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!

Florida Native: Muhly Grass Muhlenbergia capillaris

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.

 

Leaf Spots Abound on Hydrangeas this Time of Year

Leaf Spots Abound on Hydrangeas this Time of Year

It is not uncommon to see leaf spots on your hydrangeas during late summer and fall.

These spots are caused by a number of fungal diseases. Plant fungi and wet weather go hand-in-hand. Florida’s high humidity, heavy dews and frequent rains during spring and summer provide perfect conditions to allow fungal diseases to flourish. Bacterial leaf spots can be part of this foliage disease mix, too.

Common foliage diseases seen on hydrangeas this time of year include Phyllosticta leaf spot, Target leaf spot, Bacterial leaf spot, Botrytis and Cercospora leaf spot.

These foliage diseases are the norm rather than the exception as we move into the wet summer months and on into fall. As a matter of fact, you would be hard-pressed to find any hydrangea in our area without some evidence of infection now.

This late in the year it is more of a “grin and bear it” problem. In other words, it’s too late to do much about the fact that your hydrangea plant has leaves covered in ugly spots. By now many of the infected leaves are turning brown, withering and dropping prematurely from the plant.

Cercospora leaf spot is one of the most common foliage diseases of hydrangeas. Along with most of the leaf spot diseases, it begins as small dark-colored specks on the leaves. The small specks generally go unnoticed. But as the spots continue to slowly enlarge, mostly maintaining a circular shape, they become more obvious. With heavy infection, individual spots can coalesce forming larger irregular shaped brown areas on individual leaves. The individual spots may have a purplish halo with gray center.

There are some fungicides that can help prevent these leaf spots. But you’d have to begin treatment early in spring before any leaf spots exist and spray the plant every 10 to 14 days during favorable disease development (humid, rainy weather), which is pretty much our spring and summer months. These types of diseases are prevented, not cured. That’s the “grin and bear it” part of waiting until now.

The fungus survives on infected leaves. So, the best thing to do now is to remove and dispose of infected leaves. Also, be careful to not wet the leaves when irrigating the plants during the growing season.

New leaves of spring should be spot/disease free as they emerge. But the cycle of life for these leaf spot diseases will again result in spotted/diseased leaves on your hydrangeas next summer and fall without persistent treatment.

The good news is that these leaf spot diseases normally do not cause permanent/long-term damage for hydrangeas. They just make the plant look ugly.
