Camera practice at the Wildflower Center


Sea holly, or eryngo (Eryngium leavenworthii)

I tried watching an instructional DVD about using my new camera on Sunday but fell asleep halfway through. When I awoke I decided a real-life test drive should be the first step, at least to try out the semi-automatic settings. So I headed to my favorite strolling garden in Austin, the Lady Bird Johnson Wildflower Center, to see what the new toy could do. Or rather, what I could do with it. Suffice to say, not much at this point—I mean, not much that I couldn’t already do with my old point-and-shoot. I aspire to learn the manual settings eventually. Meanwhile, the semi-automatic settings appear to work quite nicely.


Liatris and yucca

My old point-and-shoot, which I’ve been quite happy with for 3 years, is a Canon PowerShot S3 IS. But recently I decided to make the leap to an SLR. My new camera is a Nikon D5000, which I chose based on personal recommendations, online reviews, and handy extras like an articulating LCD screen.


Gayfeather (Liatris mucronata)

First impressions: This camera is significantly heavier than my P&S. I find it a little harder to use for macros because of the weight, but I expect to adjust for that in time. It does a much better job with reds than my old camera, which had difficulty rendering them in sharp detail without oversaturating the image with color. And in an indoor test run, it did a fantastic job with low-light interiors. As for the garden pics, I’m pleased with its performance and know that I can do more as I learn the ins and outs of this camera.


Grape arbor

Now I’ll shut up and let you enjoy a warm, late-summer afternoon stroll at the Wildflower Center. What a contrast with today’s steady rain and cooler temperatures, which seem much more fall-like. Remember that all the plants at the Wildflower Center are native to Texas (mostly central Texas), and the gardens are a great source of inspiration.


Turk’s cap (Malvaviscus arboreus var. drummondii)


Turk’s cap is a magnet for hummingbirds.


Turk’s cap and flame acanthus (Anisacanthus quadrifidus var. wrightii), a hummer’s fantasy combo.


Cardinal flower (Lobelia cardinalis)


Bottle tree, part of a folk art exhibit at the Wildflower Center now through December 5.


American agaves (A. americana) and Mexican feathergrass (Nassella tenuissima) in front. That’s probably Gulf Coast muhly (Muhlenbergia capillaris) in back.


An enormous datura (Datura wrightii) planted in a stock tank had sprawled to about 9 feet, with dozens of creamy white blossoms tightly furled and waiting for dusk to open.


The honeybees, knowing they’d be asleep by then, just couldn’t wait. They were frenzied to get inside the blossoms, and pushed and pulled at each other to start spelunking for pollen.


Must be good stuff!


American beautyberry (Callicarpa americana), one of my favorite fall shrubs, was in full berry along every shady path.


And Texas persimmon (Diospyros texana) was fruiting.


I love the play of sun and shadow here: Texas redbud (Cercis canadensis var. texensis), Mexican feathergrass (Nassella tenuissima), and silver ponyfoot (Dichondra argentea).


Virginia creeper (Parthenocissus quinquefolia) adorns the wall of the cistern-tower.


Its blue berries and red stems make a pretty combination.


The outdoor dining area in the main courtyard


The cistern-tower is the landmark building at the Wildflower Center. A stone tunnel leads you inside to a spiraling stair. Halfway up you can look down through a grate at the water collected inside or up through a grate to the sky. From here a narrow stair continues on the outside of the tower up to an observation platform at top.


A handful of very xeric plants, like prickly pear (Opuntia), grow in a wall planter at the top of the tower.


Back down to earth, a perky sunflower (I didn’t get an ID) waves goodbye to you and to summer.

August doldrums Bloom Day


This Bloom Day post may fool those who skim the pictures without reading the text. You could be led to think that quite a lot is blooming in my garden right now, when really it’s just a few agastaches, some ornamental grasses, and a few tiny, scattered flowers on the xeric plants. It’s August, after all, and I have a mostly shady garden. Here we go,though. Central Texas natives are marked with an asterisk (*).

Pictured above, an orange-red globe mallow (Sphaeralcea ambigua).


*Purple skullcap (Scutellaria drummondii)


‘Tangerine Beauty’ crossvine (Bignonia capreolata)


Agastache ‘Desert Sunrise’

*Winecup (Callirhoe involucrata)


Dwarf Mexican petunia (Ruellia brittoniana ‘Katie’)


*Zexmenia (Wedelia texana) poking up through bamboo muhly grass


Ruby grass (Melinus nerviglumis ‘Pink Crystals’)


Purple fountain grass (Pennisetum setaceum ‘Rubrum’)


‘Helvola’ water lily

To see what’s blooming in gardens around the world on this date, visit May Dreams Gardens for links to other Bloom Day posts.

And don’t forget to celebrate your non-blooming garden goodness tomorrow for Foliage Follow-Up. It’s easy to participate. Simply post about your favorite foliage plants for August, and leave a link to your post in the comment section of my Foliage Follow-Up post (which will be up just after midnight). Thank goodness for fabulous foliage during the August doldrums, right?

Cool summer color in foliage & flower

Filed under: 2nd garden--2010, Agaves, Succulents, Vines, Xeric plants — Pam/Digging @ 6:34 am


The beautiful, powder-blue leaves of Wheeler’s sotol (Dasylirion wheeleri) show that garden color need not be all about flowers, even in summer.


Its soft blue is the visual equivalent of a tall glass of ice water on a hot day.


Similarly, the glaucous foliage of these xeric plants adds cool color in a raised bed. The big, blue agave is my beloved ‘Whale’s Tongue’ (Agave ovatifolia). In front, from right to left, are Agave americana mediopicta ‘Alba’ (in tin pot), Agave victoriae-reginae, purple skullcap (Scutellaria drummondii), silver santolina (Santolina chamaecyparissus), ‘Chocolate Chips’ manfreda (M. undulata), Gazania, santolina, and gopher plant (Euphorbia rigida). The purple flowers cascading from the right are winecups (Callirhoe involucrata), a few of which are still blooming in summer’s heat.


A closer look at the scrumptiously named, wavy-leaved Manfreda undulata ‘Chocolate Chips.’


Agave stricta has a nice blue-green/chartreuse color scheme going on.


But for those who crave cool summer color that isn’t spiky, how about pink abutilon?


This is its first summer in my garden, planted amid live oaks in dappled shade. It is holding its own in dry shade with a single weekly watering. It also survived last winter’s deep freeze—pitifully, mind you, but it did survive.


Pam’s pink Turk’s cap (Malvaviscus ‘Pam Puryear’) is a soft-hued alternative to our native red Turk’s cap. I find it to be not quite as hardy or vigorous as the red variety, but it’s still performing well in dry shade with a little morning sun.


And, surprise! The ‘Etoile Violette’ clematis has offered up a summer flower. It blooms heavily for a short time in spring, but this is the only flower on it right now. All the more reason to enjoy it.

Stay cool!

Garden Designers Roundtable: Move over, prom queens! Give other plants a chance


Image courtesy of morgueFile

Do certain gardens remind you of high school, where everyone orbits around the popular girls—Rosa (KnockOut), Stella (D’Oro daylily), and Myrtle (crepe)—simultaneously admiring their peppy beauty and begrudging their general domination? I’m not talking about mean girls. After all, Rosa, Stella, and Myrtle are as nice as can be, undemanding and sunny. But when they are always elected prom queen, cast in every school play, and chosen to lead every club, it can get a little oppressive. Don’t let your garden be like high school. Invite some of the less popular kids to join the in-crowd by choosing a few of the following underutilized plants.


‘Sparkler’ sedge (Carex phyllocephala ‘Sparkler’). Do you have a dark, shady corner? Forget about those prom queen impatiens. Instead brighten up the shade with the cream-and-green evergreen stripes of Sparkler sedge. I find it performs best in bright or dappled shade; it will not be happy with long periods of direct sun, particularly afternoon sun. I expected it to be thirstier when I first planted it, but it has proven fairly drought tolerant once established. More good news: deer ignore it. Last winter’s deep freeze turned some of the lower leaves brown, but the plant survived with no protection. The only downside is that it can be difficult to find in nurseries. I’ve seen it locally at both Barton Springs Nursery and the Great Outdoors but not consistently. Your best bet, Austin gardeners, would be to call one of these nurseries and put in a request now for a spring shipment.


‘Black Pearl’ ornamental pepper (Capsicum annuum ‘Black Pearl’). This goth girl is my new favorite annual. Dressed in dramatic black leaves, she doesn’t give a flip about being prom queen. She won’t stop traffic with colorful flowers. But she knows how to create drama with dark foliage that contrasts beautifully with the brighter hued leaves and flowers of her garden companions, and she accessorizes with stunning, black, pearl-like peppers that turn red as they ripen.


Part sun to full sun increases the blackness of Pearl’s leaves; she’ll need a little extra water when it’s really hot to stave off wilting. You’ll find her in early summer at independent nurseries and the big home-improvement stores.


Sotol (Dasylirion). Agaves are deservedly popular here in central Texas, but sotols are the forgotten stepchildren, probably because they are less than impressive in a 1-gallon pot. After a few seasons in the ground, however, sotol grows into a spherical, shimmering focal point, catching the light with hundreds of tiny teeth arrayed on flexible, strappy leaves. Heat, cold, and drought tolerant, it requires only plenty of sunlight and sharp drainage to do its thing. Wheeler’s sotol (Dasylirion wheeleri), pictured above, is my favorite because of its blue coloring. Native to west Texas and the desert southwest, it grows well in Austin with good drainage.


Gorgeous in green, Texas sotol (Dasylirion texanum) is native to central Texas and can be spotted growing wild on rocky escarpments. Both varieties, as well as a few others, are easy to find at independent nurseries like Barton Springs Nursery and the Natural Gardener.


Agastache. I planted a number of agastache in the spring of 2009. Now I wonder how I ever got along without them. These desert-southwest natives need good drainage, lots of sun, and a little elbow room to avoid powdery mildew, but when you find the right spot and give them a couple of seasons to get established, they really put on a show. Agastache has an airy form of tiny leaves on upright stems, just like many of our native xeric plants. It won’t look like much in a one-gallon pot. But after a season or two in the ground it takes off and puts on a colorful show from mid-summer through fall with tubular, hummingbird-attracting flowers. Agastache ‘Desert Sunrise,’ pictured above, is one of the best performers in my garden.


Agastache ‘Acapulco Salmon & Pink’ is also rocking out in combination with cleome, phlox, and ‘Black Pearl’ pepper. The common name “licorice mint” gives a clue that agastache’s leaves are fragrant, which also means deer don’t like it. Check out High Country Gardens online for a good selection. (Full disclosure: Owner David Salman sent me a collection of agastache as the prize for a photo contest back in 2009.)


Snapdragon vine (Maurandella antirrhiniflora). If you want a flowering vine that won’t overwhelm your arbor, much less your house, that loves heat and sun, try this deciduous, dainty climber with ivy-like leaves and purple, snapdragon-like flowers. It dies back in winter but is hardy to 20 degrees F. I cut mine to the ground after a few hard freezes turn it brown. In spring it quickly clambers back up, to around 8 or 10 feet if given adequate sunlight.


Snapdragon vine climbs by twining, so affix a length of thin wire or jute twine where you want it to go. I’ve found it for sale at Natural Gardener and Barton Springs Nursery.

So there you have it—five plants that will shake up the high-school pecking order in many an Austin garden. Keep in mind that these plants are suitable for central Texas growing conditions. If you live elsewhere I can’t speak to their suitability for your climate, but do check out today’s posts from the other participants of Garden Designers Roundtable to see what regional plants they suggest for the topic “Underutilized Plants.”
