Hot. Pink.

Central Texas bounced through spring, skipping over late May and June, and landed, smack dab, in July.  Or so it seems when venturing outdoors.  It’s hot here, hotter than it should be in late spring, and hotter than this perspiring gardener prefers.  Don’t get me wrong, I don’t mind the heat–in July, August, and I’ll even tolerate it for some of September.  But as the temps creep ever closer, day-by-day, toward 100F / 38C (in the forecast for the next few days), this toasty trend heralds the coming of the The Long Hot of summer here in Austin.

The heat is a little early for my taste, but as the saying goes:  Everybody talks about the weather, but nobody does anything about it.

These Rock rosePavonia lasiopetala, are also hot, hot, hot, but in the pink sort of way.   I’m certainly not complaining about them.

The sunflowers nod their approval of Rock rose.

Most of my Rock rose began blooming toward the end of April and are still pinking-up the garden.  I’ll prune them in the next few weeks as they bloom best on new wood.  They’ll continue to flower in our hot weather and with minimal water, but the flowers will close in mid-afternoon to conserve moisture.

We all hunker down in the heat.

Rock rose mix nicely with other early summer bloomers, like Big red sage, Salvia penstemonoides, and YarrowAchillea millefolium.

I transplanted the Big red sage in the fall from my increasingly shady back garden. They’re much happier here.  The Yarrow is also blooming better now that the front garden receives more sun.

 

This little guy looks like he’s waiting for me to leave, so that he can enjoy his breakfast of petals or leaves.

Look closely at the pollen grains on his legs.

I prefer seeing this little gal.

Slurp, slurp with her little bee proboscis.

 

Summer has arrived: time to don hats, slather sunscreen, gulp water, enjoy (or tolerate) the heat,

…and value the flowers of summer.

 

Rock rose (Pavonia lasiopetala): A Seasonal Look

If you’re a fan of pink, this is the post for you!

Rock rosePavonia lasiopetala, is a small shrub adorned with blooming Barbie-doll pink flowers through much of the growing season.  In my Austin garden, the first blooms appear in late April, with stragglers showing up as far into the calendar year as early December.  The charming hibiscus-like flowers,

…framed by fuzzy, scalloped foliage, are congenial and reliable garden partners.  A water-wise perennial shrub, Rock rose flowers are visited by many winged things:  butterflies, bees (both native and honey), and hummingbirds.  I guess all that pollination activity explains why they seed out so readily–I always have many seedlings to share.

Honeybees and several varieties of native bees regularly work the blooms. Most of the butterflies who visit Rock rose blossoms are smaller skippers and hairstreaks.

With its mallow blooms ranging from subtle, sweet pink,

…to garish, stopp’em-in-their-tracks pink,

…this shrub is a must-have for anyone gardening in Central Texas and southward into Mexico.

Masses of blooms

A single flower paired with blooms-about-to-happen. Rock rose isn’t a host plant for any insect that I’m aware of, but someone’s been nibbling at these leaves.

 

In winter, Rock rose retains some of its leaves, but definitely thins out;  I guess I’d label it as semi-evergreen.  I typically wait until late February to prune back  the shrubs to about 10-12 inches in height.  In fact, I just completed this winter chore.

Look closely to see the nearly naked limbs of February just-pruned Rock rose shrubs.  This garden boasts a cluster of Rock rose shrubs which border a walkway.

As with all things winter in my zone 8b garden, now is a good time to prune and clean out garden detritus which has accumulated.

The leaves of my American sycamore, Platanus occidentalis tangle in the web of Rock rose limbs.

 

Throughout March and April, the foliage will return–vigorous and verdant–ahead of the rosy charmers.

This is an April shot of several Rock rose shrubs bordering a walkway.

The first set of blossoms sprout in spring, blooming prolifically through summer, depending upon rainfall and /or irrigation.

Opening at dawn, the flowers remain available for critter pollinating and gardener viewing until afternoon, when they shutter their petals for the night.  As summer temperatures creep upwards, the blooms close earlier, often by mid-afternoon.  This is especially true of those growing in full sun. Well, why not??  It’s hot out there and closing the flower shop early in the day is how these plants conserve moisture during the dry, toasty summer months.

Because Rock rose produces masses of flowers, with heaps of seeds following, I typically prune a second time, by about one-third, sometime between  May and late June, depending upon rainfall.  I do this for two reasons: one–to limit seed dispersion after blooming (read: a good, old-fashioned “dead-heading”);  two–to shape the shrubs and encourage new growth.  Rock rose blooms on new wood, and if the gardener prunes the shrub 2-3 times in the growing season, the plants look tidier.  That said, I’ve seen many Rock rose shrubs go unpruned during the growing season and the worst result is that they’re leggy and floppy and produce multitudes of seeds, resulting in more Rock rose plants.

That’s not a bad thing.

Flowers open alongside developing and developed seeds.

Rock rose is a stellar summer bloomer, even during drought, but the flower show  declines unless there’s measurable rainfall.  In the driest period of summer, supplemental watering is appreciated, but Rock rose is a water-wise plant and thrives without much irrigation.

I  prune once more in late August, ahead of the autumn rains, shorter days, and the promise of cooler temperatures.  This readies the pink wonders for their autumn show!

As the temperatures cool in autumn, the flowers still open early, but  stay open until sundown.

I like Rock rose planted in groups of three, or more.  This maximizes visual impact in the garden and pollinators have plenty of pink to partake of.   It combines beautifully with other plants:

Rock rose paired with Katie’s Dwarf Ruellia.

One of my favorite combinations is rosy Rock rose planted with sunshine yellow Zexmenia (Wedelia acapulcensis var. hispida).

Rock rose, Zexmenia, and Purple coneflower (Echinacea purpurea) are a winning combo in spring and summer.

 

Rock rose performs best in full sun, but handles significant shade, with diminished flowering; I wouldn’t recommend it for deep shade. Shrubs growing in shade (and sometimes, those in sun) may develop mildew on the foliage.  Typically, the mildew resolves and other than temporary unsightliness, isn’t an issue, but it’s something the gardener should consider when choosing to plant this perennial.  When it happens, I prune offending shrubs and the foliage rebounds.

Another issue with Rock rose is its proclivity for seed production.  If you grow this shrub, you will have Rock rose babies each year.

The Rock rose which border the raised bed are all volunteers. They’ve grown out of the crack between the retaining wall and the driveway.  Even in full, west sun, these Rock rose shrubs never wilt.  Who knew that concrete is such an effective mulch?

You can pull seedlings and compost, transplant them elsewhere in your garden, or give them away.  More than likely, you’ll do all three of those things.  The seed bounty of this native plant–while annoying–is a gift.

From left to right:  two open blooms, a bloom about to open, a newly closed bloom with developing seeds, and in the background, a seedhead with seeds nearly ready to disperse.

When my shrubs develop this many seedheads, I grab my Felco pruners and have at it!  I prune the branches as little as 4-5 inches to as much as 12 inches, all depending upon how big I’ve let my shrubs get (ahem!).  The goal is new stem growth and a new set of blooms.

The seeds in the middle of this photo are ready for dispersal.

Newly formed seeds (green) and mature seeds (brown).

As well as providing for pollinators, I have witnessed various finches nibbling at the seeds, so Rock rose’s worth for wildlife extends beyond the blooms.

For those gardening with deer guests, Rock rose is only mildly deer-resistant.

Rock rose is not a long-lived shrub.  I’ve read that individual plants live approximately 5 years.  I can vouch that some of my plants have died at around 5 years, but most have lived far longer.  If you notice foliage turning yellow and  withering as if needing water (and you’ve irrigated or have had rain), don’t try to save the plant–it’s done.  Your best bet is to yank it out and plant one of the many seedlings which have popped up in your garden.

Rock rose is a lovely, tough, blooming shrub providing plenty for pollinators and birds.  It requires some maintenance during the growing season in the form of regular pruning, but is otherwise an easy-peasy plant to grow, with rewards aplenty.

Bees in Bloom

I suppose the title should read:  Bees in Blooms.

Bees of all stripes and wings are active in the late summer garden, sticking their probosces into the depths of flowers and reveling in pollen. This week, I’m crowning the honeybees as the winners of the bee beauty pageant. From a purely self-interested standpoint, honeybees are significantly easier to photograph, as they’re not speed fliers, nor teeny-tiny, like most of the native bees.

A preferred nectar source for honeybees are the charming blooms of the Coral Vine, Antigonon leptopus.

I grow one small bit of this vine and from late summer into fall, the bees are all over it, all the time.  Tagged as an invasive plant here in Texas, as well as some other southern states, in all the years I’ve grown my vine I’ve only seen two or three seedlings develop. That said, I probably wouldn’t grow it if I live in a rural area and not smack-dab in the middle of a city, at some distance from a green belt.  Rural gardeners should steer clear of this plant and choose native-to-region plants instead.

Honeybees enjoy the flowerets of FrostweedVerbesina virginica, a native perennial best known as a migrating Monarch butterfly favorite and a post hard-freeze ice-sculpture plant.

Majestic sageSalvia guaranitica, is lush with its royal blooms this wetter-than-normal summer.   Typically, I see one or two native bee species at this plant, but honeybees have shown interest in stealing nectar.

imgp9706_cropped_3318x2368-new

 

ZexmeniaWedelia texensis, always hosts a variety of  native pollinators who work its cheery yellow blooms;  honeybees are included in that mix.

Garlic chivesAllium tuberosum, recently began their short bloom cycle in my garden, but it didn’t take long for the honeys to find them.

imgp9732_cropped_2737x2585-new

imgp9728_cropped_2728x2626-new

I wonder what garlic honey might taste like?  Mmmm!

 

Another perennial preference of honeybees and many other pollinators is the Rock rosePavonia lasiopetala.  I like this back-lit shot with the early morning sun, setting bee and bloom aglow.

As well as this shot, which simply highlights both–and the foliage, as well.

An impulse buy from a nursery a couple of years ago as I observed honeybees clamoring for nectar from its blooms, is this Shrubby blue sageSalvia ballotiflora.

imgp9739_cropped_1663x1594-new

I’d say that the bee is busy and content with its bounty.  The Shrubby blue sage also attracts several species of native carpenter bees, as well as a variety of butterflies.

 

The native-to-South Texas, Yellow bellsTacoma stans, always has bee visitors, but rarely (or so it seems)  at the angle that I can easily photograph.  No bees at this bloom cluster, but these flowers always please.

A bee-less photo, but of a great bloomer and nectar source for many different pollinators.

 

Another bee-less photo is of blooming Garlic chives and in the background, a purple blooming Autumn sageSalvia greggii.

 Both typically have pollinators in attendance; I happened to catch the combo in a quiet moment.
