March to Spring!

Here in Austin, Texas (zone 8b), gardener giddiness is palpable.  Gardens and wild spaces are greening up and blossoming out.  It’s March!  Spring–visual and meteorological–is imminent, and daily garden evolution attests to that reality.  The first blooms in my garden have appeared and are set to lead the botanical charge for a new growing season.

Giant spiderwort, Tradescantia gigantea, is a native wildflower and a reliable early bloomer.  Individual plants take their turns blooming, feeding pollinators, and setting seeds throughout the spring months.  Summer heat renders Spiderwort dormant.

Rainfall is welcome for new spring blooms.

 

Globe mallowSpaeralcea ambigua, is not native to Central Texas, but instead, to points west.  In full sun and with good drainage, this gorgeous shrub is a cool season bloomer in Central Texas.

A hungry honeybee joined me in admiration of the blooms; I looked and admired, but she has more “wings” in the game.

When she flew off (to one of my backyard hives?), she was covered in pollen!

More blooming goodness is on the way–for honeybees and all other pollinators– awakening from winter and revving their pollinating engines.

Happy March! Happy Spring!

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.

BIG B, little b, What Begins with B?: Wildlife Wednesday, February

BIG B, little b, what begins with B?   

In my case, it’s not Barber baby bubbles and a bumblebee, but BIRDS, Birds, birds! With apologies to the Dr. Seuss children’s book which whimsically teaches the ABCs in classic Seussian-style, this month in my garden has seen a variety of both upper case (BIG) and lower case (little) birds.  Welcome to Wildlife Wednesday, a monthly huzzah for wildlife and also for those who garden to protect and support that wildlife.

I’ve never witnessed as many up close and personal daytime raptor encounters in my own garden as has been the case for the past couple of months.  During late autumn, winter, and spring, I regularly see raptors swooping through the neighborhood, scattering terrified birds, as well as soaring through the Austin sky as I make my way around town.  But this past month, several have hunted directly in my back garden, with exciting, sometimes troubling, results.

A gorgeous Cooper’s HawkAccipiter cooperii, flew into a sliding-glass door which serves as the door to my back garden.  I happened to be out in the garden and it must have flown passed me on its way to the crash.  I heard the thump against the glass door and whipped around, assuming that it was a Whitewinged dove, as those are the birds that typically hit the windows.  I was shocked to see the hawk on the back patio floor, a bit unsteady on his talons.  He fluttered to a bench adjacent to the door, and then flew to a back trellis.

I thought the hawk might be a juvenile, but the deep orange eyes suggest an adult.

With one more addled act, he landed on a pathway about 10 feet in front of me.  After minute of giving me the stink eye and allowing me the time to grab some photos,

…this beauty flew to a neighbor’s tree and then was off again, flying well.

A few days later, I saw a Cooper’s Hawk in my Red oak tree; I assume it’s the same hawk, as it hangs around my house, clearly looking for bird meals.

The hawk’s eyes are focused on what I realized was a dove, its targeted meal.

A split second after this shot, the bird belted toward the back of the garden and with a rustle of leaves and kerfuffle of activity, a Whitewinged dove sprinted into the air and across the neighbor’s back garden with the hawk in fast pursuit.  I lost sight of the two of them as they winged through trees in the ancient predator-prey dance, so I don’t know how the chase ended.

I’ve noticed a few more bird strikes on my windows since I had Pella windows installed about two years ago.   While I love the windows, I’m sorry that it’s created a problem for the birds. The vast majority of hits are of Whitewinged doves, and only one proved immediately fatal, but I can’t help wonder how many hit when I’m not home?  And, do any die later, from internal injuries?  I‘ve placed “bird alert” window decals on many of my windows, though I’d never placed any on the sliding-glass door that the hawk hit;  I’ve remedied that.  (My back patio is covered and I mistakenly assumed a bird wouldn’t fly fast into such obviously human territory.) The reviews of these decals are mixed, but they apparently have some positive effect on the birds’ view of things.  A quick look at one of my back windows gives you an idea of what the birds see.

This window images part of my back garden and the back neighbor’s roof. You can also see the stickers, placed  closely together.

As far as I’m aware, no bird has hit this particular window, but you can see why one might.

At about this time last year, I witnessed another Cooper’s Hawk chasing birds in my garden.  It flew from the house to a Mountain Laurel tree (mid-garden), and then immediately whooshed back to the house, straight toward a bedroom window.  The bird banked hard to its left about three feet from the window and flew off.  I’d placed some decals on that particular window and have often wondered if the bird saw the decals and realized that it wasn’t open space.

I’m now lowering the blinds in my windows, especially when I’m not at home, as bird researchers think that the slats help the birds to see that the window, even if reflective, isn’t open space.  Another recommendation is that if you have a window with an opposite window in the same line of sight (where you can see all the way through the house) which might give birds the illusion of open space, close or lower blinds on the second window.  It will diminish the look of greenery, trees and sky that birds think they see.  For more information about how to reduce  bird strikes, check out this article from Cornell Lab of Ornithology.

Along with the active Cooper’s Hawk, there are two Red-tailed HawksButeo jamaicensis, at least one of which  I’ve seen a couple of times diving through my garden in search of  bird à la feathers.   As well, a Great Horned OwlBubo virginianus, prowls at night; I’ve heard and seen it several times.  I can’t tell if it’s a single, or one of a pair, but it’s big.  Really big.  While the predator birds have been unusually active this winter,  I haven’t seen or hear any evidence of Eastern Screech Owl,  Megascops asio, activity.  We’ve welcomed mated pairs for the past 8 years, enjoying their parenthood antics and darling offspring.  Last year, we missed hosting a pair because of an oppossum in the owl box.  This year, the owl house is clean, empty and ready for the little owls, but they’re a no-show.   It might be fear of the hawks or the Great Horned Owl, but it’s unusual–and concerning–for there to be no Screech owl activity this time of year.  I am also concerned about neighbors who place rat bait stations around their property.  Do the bait traps contain rodenticide, or substances that repel, rather than kill rodent?  Poisoned rodents lead to poisoned raptors. 

As for the little birds, there are plenty and they are quick.  I briefly witnessed this Blue-headed Vireo, Vireo solitarius, bathing in the bog and fluffing feathers in the winterized Yellow bells, Tacoma stans.  

I’ve seen this species of bird before during spring migration and I wondered if this one was misplaced.  In fact  All About Birds shows that Central Texas is on the cusp of the vireo’s winter habitat. He made one brief visit,  but he’s welcome anytime.

While on a walk in my neighborhood, I snagged a shot of a quick-moving female (?) Downy WoodpeckerPicoides pubescens.  Darling little wood lovers, I’ve limited success with decent shots of these rapid-fire tree huggers; these are the best I’ve managed.

Up in a tree a few streets away from my house.

Nibbling at the suet feeder in my garden.

Downy woodpeckers sing a charming chirp and are common in my neighborhood, but apparently, shy with bird paparazzi.

As for poor quality bird photos, I’m posting these of a Ruby-crowned KingletRegulus calendula.   My current camera, coupled with a bordering-on-a-character flaw lack of patience, removes any expectation of achieving clear shots of this tiny dynamo, topped by a flaming red cap, so I’m  going for broke on photos of this bird and not fretting over the less than stellar quality!

Look at that red, albeit smeared, head!  Males like to flash their color when they’re defending territory, impressing ladies, or expressing annoyance.  This one likes to bathe in the bog, then fluffs-n-dries in the adjacent Yellow bells shrub.  When he’s fluffing and drying, he’s as still as he gets; otherwise, he’s constantly on the move for insects.

This shot of him in the bath is, well, at least clear!  I assume there’s no red crown because he’s relaxed and enjoying his bath.

I’ve seen two of these itty-bitty birds simultaneously, but usually there is only one in the garden or at the pond at any point in time.

 

Other little birds regularly visiting are finches.  Lots of finches.  One American GoldfinchSpinus tristis.  

He has the food bar all to himself.

Two American Goldfinches.

Share nicely!

Two Americans, plus a House FinchHaemorhous mexicanus.

This food bar is becoming popular!

Three Americans, a House, and an upturned tail feather owner–probably another House Finch.

The sign of a successful eatery: long waits before seating!

I can’t help wondering what rhyming silliness Dr. Seuss would posit about these feeding finches.

The resident birds and winter visitors represent garden life in this dormant time of year, adding color, interest, and activity.  Who’s visiting your garden?  Please share your photos and stories of wild critters this past month.  Remember to leave a your link when you comment.
