Welcome Late Bloomers

Magnolia 'Jane' bud

As a comment on my last post, my fellow Kansas blogger Br. Placidus asked if my garden had "burst into bloom like a desert after a storm?" following the recent rains.  Yesterday, as I was mowing, I saw that it was indeed coming alive, new growth perking up here and there, and of course, weeds and more weeds everywhere!  I'm trying to stay ahead of the weeds, but the crabgrass is advancing on a massive front and I'm being flanked and overrun left and right.  There are a few sporadic roses blooming, primarily 'Polar Ice' and 'Iobelle', but many are showing a few buds and suggesting I should have hope for a late September R. rugosa rampage.

Lagerstroemia 'Centennial Spirit'

Oddly though, the plants that are the most visible bloomers right now are plants that I wouldn't have even tried to grow in my garden two decades ago, those I would have been afraid to attempt when I was solidly Zone 5.  The crape myrtles in the garden are all presently blooming profusely, beacons of color spotted around the garden.  In fact, Mrs. ProfessorRoush, peering from the gloom of the house during one of the recent rains, asked me if the bright red plant 80 feet away was a red rose.  Nope, Honey, that's 'Centennial Spirit', which annually reaches around 4-6 feet in my garden (4 feet in this drought year). and then dies back every year.  Thankfully, crape myrtles are one flower that rain doesn't seem to blanch or destroy.

Lagerstroemia 'Tonto'

The other crapes that I have, red and short 'Cherry Dazzle', tall and slender white 'Natchez', a lavender crape myrtle saved from a city bed destined for destruction, and squat purple-pink 'Tonto', are all blooming now as well.  'Tonto', pictured at right, sits as the lone tall plant in a bed of daylilies, anchoring the bed for me and drawing attention away from the weeds among the daylilies at this time of year. 

The most surprising bloomer however, is magnolia hybrid 'Jane', one of the 'Little Girl' ‘hybrids developed at the National Arboretum in the mid-1950's by Francis DeVos and William Kosar.  A cross between M. liliiflora ‘Nigra’ and M. stellata ‘Rosea’, 'Jane' blooms about two weeks later than M. stellata in my garden, usually profusely in early April and usually just in time to get its petals browned by a late frost.  What most printed sources don't tell you, but I've seen several times, is that 'Jane' will repeat bloom, albeit less prolifically, in the fall. I've seen occasional blooms on my darker-pink 'Ann' as well, although she seems to be lacking them this year.  I did find one forum entry that discussed reblooming of liliacs, and one of the respondents indicated that M. stellata, M. liliiflora, and M. loebneri may rebloom in summer.  Since 'Jane' and 'Ann' are hybrids of the two former species, I guess it makes a little sense to see them rebloom.  Sporadic though they might be, that brief promise of magnolia fragrance in the off-season is a welcome gift from my garden. 

Black Diamond Blush

Orange may be the new black, but ProfessorRoush believes black will always remain in style, nonetheless.  Women never go wrong with a simple basic black dress and pearls, and well-turned out gentlemen seldom look out of place in black suits and white shirts.  In contrast, black tulips and dark roses and chocolate zinnias are novelties craved by many gardeners, but I've never jumped on that bandwagon, myself.  Does black really ever belong in the garden?

I was excited, however, late in the season last year, when I found a number of Black Diamond Crape myrtles (Lagerstroemia indica) at the local Home Depot.  I had never seen or heard of these varieties before.   Crapemyrtles as a rule are only marginally hardy here, but I couldn't resist that dark foliage as an accent plant.  Several varieties were available, but I didn't like the combination of red flowers and dark foliage on 'Best Red' , nor the off-red shading of slightly lighter 'Crimson Red'.  I chose to try out 'Blush', a white-flowered variety that is technically a very light pink, but looked primarily white in the parking lot.

This spring, it was killed back to the ground (as were the rest of my crapemyrtles), but I left the spot untouched and, sure enough, in late May, a single dark stem arose that I babied and protected throughout the past few months until it began to bloom.  And here it is, stunning at last, the earliest of my crapemyrtles to bloom and the most noticeable.  Tell me, what do you think? An entire forest of Black Diamond 'Blush' might resemble a scene from a Tim Burton movie, but I'm pretty happy with it as an accent plant.  With a little more global warming, perhaps it won't kill back to the ground and I'll be able to see it get a little larger and more prominent each year.  Happily, it seems to be both drought-tolerant and able to withstand wet spring feet, and it has been unbothered by pests, both six- and four-legged in form.

There was a little bit of sleight of hand in the introduction of the Black Diamond series.  A little bit more research led me to the information that this commercially-offered series is the same as the Ebony series bred by Dr. Cecil Pounders and registered with the U.S. National Arboretum in 2013.  Black Diamond 'Blush' is the same plant as 'Ebony Glow'.  The breeding background of these plants are detailed in the HortScience article linked above.

Now, I think I'll watch for the new purple-flowered 2015 introduction, 'Purely Purple'.  The black foliage and purple flower combination of this new crape seems tailor made for a K-State oriented garden bed, don't you agree?
