In The Garden

Hi everyone!  I thought I'd share a few photos from the garden.  It has been nearly two years since I moved and as some of you know, it took all of the first year just to get the beds whipped into shape, the weeds under control and gain some sense of control over what was already here when I moved in.  This second season in the garden has been devoted to details and I'm finally at a place where I'm getting plants in the ground every weekend.  It isn't that I haven't planted anything at all over the past two years, I've just worked bed by bed to try and get it right the first time (yeah, right!) and keep the moving of plants later on to a minimum.  Whether they eventually get moved or not, some of the plants that have been in the ground for a season or two are really settling in nicely and certain ones are really beginning to put on a show.  I thought I'd share a few of the goings on in the garden with you.  Hope you enjoy this little tour of some of the plant life around my garden.

Spring started off back in March with Hamamelis x intermedia 'Arnold Promise', one of my favorite witchhazels.

Flowering at about the same time as the witchhazel, Helleborus x ericsmithii 'Silver Moon' has quickly become one of my favorites.

Iris reticulata is a late winter/early spring bloomer that brightens up the gray days of winter just about the time you begin to wonder if spring will ever arrive.

Beginning in May and continuing on for well over a month is Papaver dubium, the common field poppy.  I love its deeply divided, fern-like foliage and the brilliant orange blooms.  It's a re-seeder, so make sure you leave the seedpods!

As I mentioned in a previous blog entry, hydrangea season was spectacular this year.  This is Hydrangea serrata 'Blue Billow' in full bloom next to the garden shed.

A closeup of 'Blue Billow'.  So beautiful!

One of my favorite shade plants, Symphytum x uplandicum 'Axminster Gold'.  Unfortunately, it's rather hard to find.

I love milkweeds! L-O-V-E them!  And this one, Asclepias variegata, is right near the top of the list.  If you need a cool plant that thrives in dry shade (or part shade anyway), this is it!  And the monarch butterflies like it, too.

Gladiolus papilio is a small-flowered, hardy gladiolus.  I got my corms from Ellen Hornig at Seneca Hill Perennials just before she decided to close the nursery.  I have at least three color forms that have flowered so far.  This one has the nicest markings, but there is another that has a more open flower.  The third is an entirely different color--a sort of mauve-lavender with grey undertones.  Quite unusual.

I love this variegated pine, Pinus densiflora 'Oculis Draconis', the "dragon eye" pine.

One of my favorite hydrangeas, Hydrangea arborescens 'Hayes Starburst', discovered by my friend Hayes Jackson in his garden in Anniston, Alabama.  This is a cousin of the popular 'Annabelle' hydrangea, but much, much more refined.  It's also a lot slower to establish and needs about three seasons in the garden to really get going.  It's well worth the wait!

And finally... flowering this week, Musa ornata 'Red Jewel', which has been hardy in a couple of gardens in the Nashville area in protected locations for the past 5 or 6 winters.  I'm not claiming it as "hardy", necessarily, but if you site it appropriately you may get it to come through the winter.  From Zone 7 south, I think it would be pretty reliable.  It sure is spectacular when it flowers!

And that's what has been happening in the garden so far this year.  New things continue to flower and each week I get more plants, some of which have lived in pots for more than 5 years, in the ground.  Hope your summer, wherever you are (or winter if you're south of the equator!) is going well and I'll be back again soon.  Happy gardening!

A Banner Hydrangea Season

Wow, time flies!  I've been trying to be good about posting and then suddenly I look up from what I'm doing and it has been THREE WEEKS!  Where does it go?!?

I'm happy to say that it has been one of the most spectacular hydrangea seasons that I can recall in the 17 years I have lived in Nashville.  Why?  Well, as much as I disliked the cold winter weather that seemed as though it might never end, the hydrangeas loved it.  More importantly, they loved the fact that once it got cold this past winter, it stayed that way.  We didn't have nearly as many wild fluctuations in temperature as we normally have and that caused tender hydrangea buds to stay dormant!  Usually, we have one of those early warm spells that lulls unsuspecting hydrangea buds into a sense of false security, so they swell, turn green--and get zapped!  That didn't happen this winter and now we're being rewarded.

My Hydrangea macrophylla varieties are beautiful this year.  They're usually the most prone to damage by early frosts and in the Nashville area we usually have one good Hydrangea macrophylla year out of every five.  But it's the Hydrangea serrata cultivars that are truly remarkable.  Words just can't describe how loaded with flowers they are!  Hydrangea serrata 'Blue Billow' has outshined anything else in the garden by far and Hydrangea serrata 'Beni' is proving itself to be an exceptional plant.  If you're unfamiliar with the "serratas", the plant resembles our common garden hydrangea (Hydrangea macrophylla), but the leaves are typically a little smaller and usually have a matte surface to the leaf rather than the glossy or semi-glossy leaf of the "macrophyllas".  The other difference is that the "serratas" are almost all lace-caps, with their delicate flowers seeming to float just above the plant.

I am frequently asked about the proper culture for hydrangeas.  Generally speaking, they prefer moist, rich, well-drained soil and plenty of water.  In my estimation, one of the most common mistakes is planting them in too much shade--even in the South.  At minimum, they really need to be sited in morning sun and the more sun you give them, the better they will usually flower.  Sunlight helps to ripen their semi-woody stems late it in the season and the more ripened and hardened off they are before winter sets in, the more likely those stems and the buds they carry are likely to survive the winter to flower the following year.

Wilting vs. Flagging.  I think it's very important for gardeners to know the difference between a plant that is "wilted" and a plant that is "flagging".  A wilted plant is one that has drooped because the soil around it has become dry and it can no longer pull water from the soil.  Water is pulled out of the leaves and into the stems for storage--a defense mechanism to try and stay alive.  A plant that is flagging has plenty of moisture at its roots, but is responding to another environmental factor--usually sun (especially with hydrangeas), but it can also be a response to a dramatic change in air pressure or humidity.

How do you tell the difference?  Easy.  Does the plant stand back up and look "normal" once the sun is no longer on it (or after the weather front passes)?  If so, then the plant has just "flagged" in response to some change in its environment.  Openings on the back of the leaf, called stomata, have closed in order to conserve water inside the plant and the plant droops.  Hydrangeas, specifically, may flag every day if they're in the sun, but as long as they have moisture at their roots, they'll be fine.  If, however, your plant has wilted from being too dry, the leaves won't perk back up, even after the sun is off of the plant or the weather has finished changing.  If you have hydrangeas that wilt in the afternoon sun but do not perk back up once the sun has gone down, they probably need a thorough soaking around their roots.

In the fall, usually around Labor Day weekend, I stop watering my hydrangeas altogether--only supplementing them if they wilt and stay wilted for more than 3 or 4 days at a time.  This is a little bit of "tough love", but I want their woody stems to ripen and harden off and a little bit of stress helps to do this.  I don't go overboard and will give them some supplemental water if their wilting persists for more than a few days, but I've found that this "hardening off" process helps me to have more reliable blooms the following season.

Guess I had better sign out for now, but I'll be back again in a week or so!  Hope your hydrangeas are outdoing themselves this year!
