Variegation Variations, Another Plant Nerd Mystery….

~

When the first red Caladium leaf with white veins and a green and red border opened, I was puzzled.  It didn’t resemble any of the 14 different varieties of Caladiums I had ordered this spring.

~

~

And so I assumed that maybe I’d received a serendipitous bonus; a rogue bulb of a different variety had made it into one of my bags.  I headed back to the Classic Caladiums website in search of the variety to learn its name.  I searched the site every way I knew how, and yet still came up empty handed.

~

Caladium ‘Peppermint’

~

By then another leaf had opened, and another, all from different bulbs.  I knew that it was indeed a mystery, but not a mistake.

When I heard from Lesley, in internet sales, on another matter,  I sent her a photo of my mystery Caladium.  She indicated that it might be C. ‘Peppermint,’ but promised to check with their CEO, Dr. Robert Hartman, and get back to me.

~

~

I went back to the information on C. ‘Peppermint,‘ which I remembered as a mostly white leaf with a little green and touches of rosy pink.  This is a 2011 Caladium I’ve admired for a while, but ordered this year for the first time.  Sure enough, the photo resembled the mostly white leaves I remembered. (In re-checking the page tonight, at the very bottom of the webpage I see a photo of C. ‘Peppermint’ with the mostly rosy leaves I’ve observed.)

~

~

All the while, our Caladiums kept growing and pumping out new leaves.  By the second week of June, I found a plant with both forms of the variegation on different leaves from the same tuber.  Now how odd is that?

~

C. Carolyn Wharton in late May

~

The older, traditional Caladium varieties are pretty dependable.  There will be some slight variations in the variegation on a plant like C. ‘Carolyn Wharton’ or C. ‘Miss Muffet,’ but not so much that you wouldn’t recognize them as clearly the same cultivar.  The leaves are more like each other and different from all other Caladium varieties.

~

C. ‘Sweet Carolina’ in September 2016 shows a lot of variation in its variegation, too.

~

But I’ve noticed a wider range of variations on leaves within a cultivar from Dr. Hartman’s new Caladium introductions.  I noticed it first on C. ‘Sweet Carolina.’ 

~

C. ‘Sweet Carolina’

~

Depending on the amount of light, moisture and nutrition a plant received, it may vary drastically in both basic leaf color, and also the pattern and amount of variegation.  I find this very entertaining, and I learned to really appreciate this decidedly odd and very large full-sun tolerant Caladium.

Caladium ‘Highlighter’ June 2017

~

When I grew out C. ‘Highlighter’ the first year, I didn’t recognize the plants for a few weeks because the color of the leaves was so variable.  I assumed that some were C. ‘White Delight.’  Some leaves were nearly white and creamy with few markings.  Others were richly colored with many strokes of pink.  But I could trace those variations to culture, because the plants were grown in different locations in the garden.

~

~

On the same plant, growing in the same conditions, the leaves were similar to one another.

~

The first leaf to open on a newly sprouted C. “Desert Sunset’ in late May appears as the reverse image of the C. ‘Peppermint’ leaf….?

~

And then came C. ‘Peppermint.’  I was doubly puzzled because the variegation on the mostly rosy leaves was like a mirror image of some of the early leaves on C. ‘Desert Sunset,’ when grown in deeper shade.  How could this be?

~

~

I hope to have the opportunity to discuss this high weirdness with Dr. Hartman some time.  He is the guru of Caladium breeding, and I am positive he has some wonderful stories to tell about new Caladiums he is breeding and the odd variations that he has observed.

I am wondering why two leaves from the same tuber would end up so different from one another.

~

Calaldium, ‘Desert Sunset’

~

I’m also wondering why the earliest leaves were rosy with white veins, but later leaves emerged mostly white, with some green and rosy pink markings.  What is going on in the plant?   Do growing conditions tip the tuber to produce one sort of leaf over the other?

~

C. ‘Peppermint’

~

There are many, many mysteries in the plant kingdom; I am only beginning to scratch the surface of the wonders of horticulture.  As with a child, what part of a plant’s growth is nurture, and what part is wild and crazy nature taking a leap to manifest as something entirely new?

I am endlessly fascinated by the work of hybridizers who delight in introducing new colors and forms of beloved plants, and new strains that are stronger, healthier and more versatile than older varieties.  They work with nature and natural processes to give us the great gift of a new and useful plant.

~

I love the new Caladiums that can take several hours of sun each day because there are more ways to use them in the garden.

~

And I am thoroughly enjoying watching all of my Caldiums grow into their potential this summer.  An ‘outed’ plant nerd extraordinaire, I just can’t get enough of observing the wonderful variations of their lovely variegation.

Pot Shots: Caladiums at Last

Caladiums ‘Chinook’ and ‘Highlighter’ blend together well.

~

All of the Caladiums are up and growing.  It took a while this year because of our crazy cool spring.

In fact, I still have a tray of C. ‘Moonlight’ on my deck, waiting for me to commit to where I’d most enjoy them this summer.  There are only 10 left, and so many places I’ve considered planting them.

~

C. ‘Moonlight,’ overwintered from last summer’s garden.  These pure white leaves appreciate bright shade.

~

Back in the day, one just assumed that Caladiums required a shady spot.  With the new hybrids, many can take full sun.  That means I am constantly checking back with the grower’s site to make sure I’m getting ‘right plant, right spot’ and not giving too much, or too little sun.

~

Caladium ‘Burning Heart’ can take full sun, so long as you keep it hydrated. This pot is finally growing into its potential!

~

I fantasized about this combo of C. ‘Highlighter’ and C. ‘Chinook for better than a year; finally it is growing and looking great in the upper garden.  C “Highlighter” seems to be out of production, which is a disappointment.

~

~

A little strange for some tastes, but it has become one of my favorites.  I am forever grateful to the wonderful folks at Classic Caladiums for sending me a bag of beautiful C. ‘Highlighter’ with my order this year, even though it wasn’t a catalog listing.  I was happy to be able to plant a few and also share a few with friends.

C. ‘Chinook’ looks much better in person than in the catalog photos, in my opinion.  I’ve been happy with it and have mixed it with several other pink Caladiums in various pots.  It is a strong grower and generous in producing new leaves.

~

A mystery Caladium on the left. We have several growing, and I’ve no idea its name. But I like it!   C. ‘Peppermint’ grows in the pot with it, on the right.

~

There are lots of new and interesting Caladiums in our garden this year growing alongside old favorites.  I try to find time to get around the garden to check on their progress at some point each day.

And every day, they just keep getting better.

A quick and easy wildlife gardening tip:

~

~

Fill a shallow saucer with a bit of sand and some pea gravel, place it in your garden, and keep it moist through the summer. 
You’ve just created a place for butterflies, other insects, and small reptiles to find life-giving water on hot summer days.

Pot Shots: A Pop of Color

~

A grouping of simple hypertufa troughs have rested here, forming the edges of a raised bed, since 2014.  I made the troughs for this purpose, and planted them that first year almost entirely in Caladiums.  A dogwood tree grows from the center of this very shady bed planted mostly with ferns and Hellebores.

Wanting year round interest with a minimum of effort, I’ve added hardy Begonia grandis, evergreen Saxifraga stolonifera, additional seedling Hellebores and various ferns in and around the pots over the seasons since.  Vinca minor and ivy volunteered themselves as groundcovers.  I have tried establishing moss around the pots, but haven’t met as much success with that as I would like.

~

~

There isn’t much space left to add summer Caladiums anymore, especially as the ferns have filled out and the Saxifraga and Begonias continue to spread themselves around.  But I still tuck in a Caladium tuber or two each spring.  This is easiest to do as the Caladium just begins to grow, before its roots grow too large for the hole I can dig in these shallow pots.

~

~

This is one of my favorite spots in the garden year round, now, and we will enjoy the intense pop of color the Caladium ‘Burning Heart’ offers with its intense red leaves.  I like how it plays off of the new Begonia leaves and the stipes of these ferns.

When growing over a period of years in shallow pots, it is important to feed the soil and keep it hydrated for best plant performance.  I top off these pots with some compost with the changing seasons, sprinkle in some Osmocote ever few months, and water occasionally with fish and seaweed emulsion in the mix.

~

These pots on May 3, before I groomed and topped them off for the season, and before it was warm enough to plant out any Caladiums.  Dogwood petals fell like snow after several days of wind and rain.

~

This composition of leafy plants holds my interest without a lot of bright flowers.  That said, we enjoy the Hellebores from January through May.

~

Saxifraga stolonifera blooms this week in another shady fern bed. These perennials send out runners, and a new plant grows at the tip of each runner. The plants root when they touch moist earth. They can fill in a large area fairly quickly and bloom by their second year.

~

The Saxifraga is blooming this month, and tiny pink Begonia flowers will emerge by midsummer.

The flowers here may be subtle, but the foliage in this bed really pops!

Pot Shots: First Caladiums

~

We are just beginning to have weather warm enough for the Caladiums to come outside and get some sun!  The ones basking in the warmth of our spare room have grown long and leggy, reaching for the light.  And so I’ve brought the other tubs and bins outside to our deck, up against the house and under cover of the eaves where they have enjoyed the warmth of our late spring and gotten a lot more light.

I’ve kept my eye on the new ones with their first leaves beginning to unfurl.  The first to open is C. ‘Burning Heart,‘ a 2015 introduction from Classic Caladiums This is one of the new hybrids from Dr. Robert Hartman that can take full sun.  It is a new color for Caladiums, and I am looking forward to growing it this summer.

~

~

Once I found that I had four of this special variety in leaf, I lifted them this morning from their bin, and brought them into the garden to the pot I have planned for them.

Already growing are two Zantedeschia ‘White Giant’.  These Zantedeschia want consistently moist soil and full sun.  This area of the garden has a high canopy of oaks, but gets a fair amount of sun during the day.  I think that it will be enough sun for them, and not too much for the Caladiums to both do very well.

Completing the pot is one of my favorite ‘spillers,’ Dichondra ‘Silver Falls.’  This silvery gray vine will spill over the sides of the pot, eventually filling in to form a nearly continuous curtain of fine foliage gradually enveloping the pot and its pedestal.  If you buy a pot of Dichondra, you will notice lots of little vines all massed together in the nursery pot.  These pull apart very easily.

A single 3″-4″ pot from the garden center could easily give you a half dozen clumps, each with its own roots.  This vine roots easily from each leaf node and may be divided again and again as you spread it around.  Although a perennial, it will only overwinter here in a very mild winter.

~

~

When we found this huge pot in February, on deep discount at one of our favorite nurseries, I hesitated over its color.  I favor blue pots.

This screaming chartreuse, in February no less, was almost too much.  It sat upside down in our nursery for several weeks while I contemplated what to do with it.  A gardening friend came by and admired it enough that she took straight off to go buy the last one like it!

~

~

Once we actually moved it up into the garden a few weeks ago, we soon realized that the green blends right in and doesn’t look brash at all…. at least not until we added the red Caladiums today!

~

~

I am working this week to plant out as many of our Caladiums, Colocasias and Alocasias as I can.  This is slow going, but will reward us with beautiful foliage plants in the garden over the next six to seven months .

~

This is Colocasia ‘Black Coral’ planted into an established planting of Saxifraga stolonifera.  Although just an old nursery pot, it is large enough to support the Colocasia as it grows to its 4′-5′ potential.  This Colocasia likes moist soil and shade.

~

We’re bringing the pots out gradually, and re-working the pots which held other plants through the winter to accept their summer tenants.   Now that the weather has settled, I want to get the plants we saved last fall out of storage as quickly as we can, so they can all begin a new season of growth.

~

Colocasia ‘Tea Cups’ is finally back outside in its blue pot. It overwintered in the garage. The soil is just warm enough to plant out these white Caladiums today. No more cold snaps, please!
