Austin Nurseries Giveaway: Emerald Garden Nursery & Water Garden

Isn’t this a beautiful fountain?

The birds love to perch on the pineapple and drink from the bubbling water.

I love to listen to the sound of moving water in the garden as I garden or just sit outside. (The gardening part is often, the sitting part, rare!)

This fountain is from the great folks at Emerald Garden.

They helped me find the right water feature for my landscape, they came out and set it up and got it all running and told me everything I needed to know.

They answered my questions about caring for it.

As we ease into fall we want to give back to the wonderful local nurseries that have helped us enjoy our gardens over the years. We know nurseries have weathered tough times lately, with the downturn in the economy and the drought, so we’re encouraging other gardeners to support them with their gardening dollars.

Cooler night-time temperatures and warm (but not baking) soil mean it’s time to get back into the garden. It’s the perfect time to replace plants that didn’t make it through the summer, make some changes to a more drought-tolerant garden or plan a new garden project to get plants established over the winter.

One of my favorite Austin nurseries is Emerald Garden Nursery and Water Garden. Owned by Trey Wyatt and Luke Hogan and managed by Jeff Yarbrough, Emerald Garden is located at 5700 Highway 290 West, just before the “Y” in Oak Hill.

For many years, I have enjoyed their plants in my garden and one of their fountains in my back yard. The birds love the fresh bubbling water (when it’s not restricted) and the sound of water in the garden is so peaceful.

The demonstration water features are woven all through the nursery, designed to inspire creativity. Water lilies and a wide range of other water plants fill the ponds and fountains.

They also have an excellent supply of disappearing fountains in every style, shape and size.

Need help? These friendly staff members will be happy to befriend you and show you around.

Their extensive statuary collection covers every style imaginable, from Zen to formal to whimsical. If you’ve lost some plants during this drought, am interesting piece of garden art might be just the thing for that empty spot.

Sometimes I wonder if the decor is there to accent the plants or the plants are there to accent the decor.

Either way, Emerald Garden has what you’re looking for.

And if you don’t want to plant anything else in the ground right now, they have a broad selection of glazed and terra cotta pottery.

Healthy specimens of trees, shrubs, vines, agaves, cacti, succulents, perennials and annuals await you around every corner. No matter what’s on your list, you’re sure to find it at Emerald Garden. And you’ll enjoy a magical tour through their delightful nursery. You can learn more about Emerald Garden here.

Fall Color in the Garden – Lion’s Tail happily wagging

The mornings and nights are finally cooler.

The sky looks just a little different.

The days are getting shorter.

And it’s only going to be 91 degrees today.

Those are the signs of fall in the Central Texas garden.

And great conditions for enjoying Garden Bloggers Bloom Day, hosted by Carol of May Dreams Gardens each month on the 15th.

It’s relief from unrelenting heat, and we’re still enjoying the effects of last weekend’s 1.57 inches of rain.

The garden seems to have been rejuvenated. There is nothing quite like a good dose of rainwater to perk everything up again.

And so it is with plants in the cutting garden. In my last post, there was a long shot of it bursting with yellows and creams and oranges, and the wild Coreopsis sneaking through the fence to join the show.

This is the star of the show. This Lion’s Tail, Leonotis leonurus, is from the Lamiaceae or mint family. It’s native to South Africa, and is drought tolerant, which explains why it’s happy in our gardens here in Central Texas.

A dwarf variety, these are only 3 to 4 feet tall. I’ve planted others in previous years and they were up to 6 feet tall.

Their unusual form and profuse blooms add wonderful color to the emerging fall garden.

Wildflower Wow

Wildflowers along our highways and byways were few and far between this year thanks to the drought.

But one little plant seems to have taken off outside of my garden.

Thanks to a some dribbles of water coming from the cutting garden bed on the other side of the fence, this wildflower has exploded into bloom in the easement beyond our property. (Like my Wisteria vine, it seems to enjoy playing hide and seek with me.)

After some research, I believe I’ve identified it as Coreopsis tripteris, or Tall coreopsis/Tall tickseed.

In any case, it’s fabulous.

I know some of those seeds are going to find their way into my hands and then into an open area (more visible!) with some fresh soil and periodic gentle hand watering this fall.

This beautiful show of color is well worth a little starting TLC to help it along.

And here it is, sneaking through the spaces in the fence to show off to the other blooms in the cutting garden.

Although it’s a little sparse because of the drought, the cutting garden has perked up in the last few weeks thanks to cooler night temperatures and our recent restorative rain.

Speaking of wildflowers, today begins the amazing Fall Plant Sale at the Lady Bird Johnson Wildflower Center. Here’s the basic information from the Wildflower Center — you can find more at their website.

Support your Independent Nursery Day


The gardening business isn’t an easy one. Local nurseries regularly face problems with weather, pests, disease and supply. This year, not only have they been faced with a rough economy, the current drought has taken an even greater toll on our local independent nurseries.

In spite of those challenges, we are fortunate to have many successful and thriving local nurseries that carry fresh, healthy plants, beautiful decor, excellent gardening products and — as important as all the tangible things — great advice. We are fortunate to have many great places for all things ‘plant’, so our fellow Austin blogger, Pam, of Digging has invited local bloggers to recognize October as “Support your Independent Nursery Month.”

This inspired idea has all of us singing the praises of our favorite haunts. I’m probably the closest blogger to the Natural Gardener – a local icon and a full family adventure located at 8648 Old Bee Cave Road, just past the “Y” in Oak Hill. Let’s just say I’m there a lot.


I always find something I want at the Natural Gardener. Their supply of native and adapted plants seems limitless and the stock always looks great. They carry only environmentally friendly organic products and excellent tools. The staff’s sense of design is insightful and selections of plants are always tucked in with shiny new pottery and garden art.

The Herb Garden, designed by garden author Lucinda Hutson, is one of my favorite destinations in the nursery, which is surrounded by large and creative demonstration gardens. They also have a butterfly garden, a stream garden, a tipi, a vegetable garden, a vineyard and orchard, a xeric garden and a compost tea brew house.
The Natural Gardener staff is always knowledgeable and friendly, recently helping me with an interview for one of my articles for the Austin American Statesman. They regularly host classes about every possible gardening subject. And the owner, John Dromgoole, one of the founders of the organic gardening movement, has long been a local superstar, appearing weekly on Central Texas Gardener on KLRU and on Saturday and Sunday morning radio shows on KLBJ (which I never miss – I get it live on my iPhone now and carry it with me in my pocket out in the garden).

But my very favorite way to enjoy the Natural Gardener is with my 8-year old daughter. We marvel over the butterfly garden, we bray back at the two resident donkeys, we cluck at the chickens and peer at the goats. Filling my cart with the nature’s beautiful specimens is wonderful. And the resident cats always say thank you from the counter as we check out. But ambling through nursery at a leisurely pace, enjoying this native Texas paradise of plants and animals (and insects), is one of my favorite ways to spend a day.

Plan to start projects now for a well-balanced spring garden

Now that we’ve had a brief hint of cooler weather, it’s time to think about fall and how we can use this time in the garden to prepare for spring.  Once the temperatures drop and we get some rain, it will be the perfect time to start planning a new landscape project.

Preparing and creating new flower beds now can actually save you money.   You can buy and put in smaller, less expensive plants this fall, letting them overwinter and get well established before spring.  This enables them to develop strong root systems so you can enjoy bigger, hardier plants when they begin to grow in the spring.

So where do you start?

Do you have a sore spot — some section of your garden that needs a little pick-me-up?  Or do you have a bed with thirsty plants that didn’t make it through the summer that you want to transform into a xeric bed?  Or are you ready for a little hardscape – an extended patio, a shed or a little garden room?

Once you determine what improvements you want to make, it’s time to start planning.

The first question to ask yourself is:  What’s my style?  Is it English cottage garden, native Southwestern, Asian contemporary, xeric, formal or informal?  What are your favorite colors?  Do you like a muted peaceful pastel garden or are hot, tropical colors your preference?  What is the architectural style of your house and my existing garden?  Do you want to do something new to complement it or do you want some contrast?

If you’re working on a garden room or new hardscape – ask yourself how you want to use the space and what you will need to make it functional and attractive.  How will it fit into the existing landscape and be a natural extension?

Next, do a little homework.  Watch the sun rise and set over your yard.  How many hours of sun does your project area get?  Knowing when and where you have sun and shade will determine what kind of plants you can use or where you might want to put a new seating area.  You’ll want to group like plants based on their water needs – if you want to create a drought-tolerant new bed, make sure all of the plants you put in it have the same water needs.

Follow a few basic rules, add a little inspiration and you can transform your yard into a fresh and inviting landscape.

Tips to designing a beautiful garden:

There are a lot of design elements to consider when creating a landscape bed.

First, think focal.  The first step is to stand back and look at the space.  Close your eyes and picture what you’d like it to be. What is your vision?  Then think about what would make a great focal point in that space. A focal point attracts the eye and creates interest. It focuses the attention of the person passing by or looking at your garden.   A focal point can be a beautiful tree, a statue, a birdbath, a bench – anything different that adds interest to your landscape.

As you begin to think of plants, harmony is your goal.  You want the plant colors in your bed to complement or contrast each other.  Colors either next to each other or across from each other on the color wheel make great combinations.

Complementary: Colors directly across from each other on the color wheel, like red and green, yellow and violet, and blue and orange. These are dramatic colors that create a bold landscape..

Adjacent: This refers to the two or three colors next to each other, such as red, red-orange and orange. Or yellow-green, green and blue-green. These are harmonious colors.

Monochromatic: This refers to a single color family with various hues or intensities. This creates combinations of subtle differences.

Primary: Red, yellow and blue. All other colors are made of these.

Secondary: Orange, green and violet

Tertiary: These are blends of primary and secondary colors; for example, yellow-orange or blue-violet. They help make the transition from primary to secondary colors.

Polychromatic: A bold mix of colors used together in a confetti fashion.

Neutral: White, gray, silver

In addition to color, texture and variegation are also important.  So that your leaves aren’t all the same green, consider combining silvery-leaved plants with lime greens to help them each stand out in their own right.  Variegated plants add interest and help brighten up shady areas.  The texture of our native agaves, yuccas and cacti work wonderfully with soft shapes and delicate blooms or fuzzy leaves.

Height and shape are also key.  A desirable combination in a bed might include some height to anchor the ends of a bed, some larger foundation plants like evergreen shrubs and then layers of slightly smaller perennials annuals or ground cover for the front of the bed.  Do your homework when planting – consider how large the plants will be at full size, not the size they are when you bring them home.  This will ensure that plants in front of a border don’t tower over the plants behind them.  If the nursery tag on the plant doesn’t have this information, you can research the plant name online and get all the data you need to know.  Most local nurseries are diligent about including all the necessary growing information.  Big box stores sometimes get unlabeled plants from far away that aren’t appropriate for our growing conditions. I shop almost exclusively at our wonderful local nurseries because my pet peeve is finding big box garden center plants labeled simply – “Perennial.”

It’s also important to consider the size and style of your yard and home so your new project matches in scope and scale.

Add movement or fragrance to the garden. We are fortunate to have a large number of pretty, xeric grasses native to Central Texas.  You can also include fragrant plants, or night blooming plants to enjoy alongside a patio space or seating area.

Now that you’ve thought about your vision for the project, start defining the space.  Sketch it out to scale on paper and include existing structures or elements like large trees.  Then “draw” the boundaries of what you want to create on the ground, using a garden hose or spray paint to outline the bed or patio and ponder it for a while.  Do you like the shape?  Is it in the right place?  Is it big enough? Too big?

Consider the other elements you might want or need to include, like irrigation, lighting, a water feature, and work inclusion of those elements into your timeline.  Sprinklers need to go in when beds are laid out but not planted to avoid having to tear out plants for sprinkler heads or lighting wires.

Creating a new garden space can freshen up your landscape and increase your curb appeal and your home’s value.  New beds and new plants can bring peace and serenity to your garden or they can brighten and liven up your entertaining areas.

As you consider new projects for the fall, remember to think xeric and look for native or drought tolerant plants that can survive our brutal summers.  Think about landscape designs that use less lawn and more hardy plants.  Using quality soils and environmentally friendly products and materials will also reward you with healthy, thriving plants once your project is complete.

Drought tolerant plants for Garden Bloggers Bloom Day


I had pictures on Bloom Day (on the 15th!) and I had most of the post done, but then … life happened. So, whether it’s the 15th or the 23rd, I still want to write about my garden and share it with you. Besides, things are still the same – no water, that’s for sure. But this morning it was a blissful 66, so hope is on the way.

We’ve had more than 86 days over 100 degrees here in Central Texas this summer. And we hit an all-time high of 112.

Our gardens are crispy and our arms are tired from dragging around hoses to hand water while we’re under water restrictions.

Only allowed to use irrigation systems for 1 day a week, before 10 am and after 7 pm, gardening has been more of a challenge than usual.

I’ve spent a lot of my time hand watering all summer long, so I have more blooms than some gardeners. I feel lucky to have had the time to devote to it.

But we do still have blooms and we’re learning more than we ever wanted to know about the true meaning of drought tolerant and xeric.

These Blackfoot Daisies are tough as nails and seem quite content in the heat.

Crape Myrtles are doing ok when they get a little water. Those with American Indian names are the most adapted to our climate.
This Katy Road/Carefree Beauty rose doesn’t seem the least bit concerned about the heat – and she’s providing some shade for the small cutting garden flowers around her.
Lord Baltimore hibiscus really came into his own this year with a profusion of blooms.
Mexican Oregano is thriving in this heat. In fact, I spent an hour cutting this one back as it completely outgrew its space and tried to take over the Sago and the nearby lavendar trailing Lantana.
Can’t kill this Datura either. Tough as nails and out of control.
Another Mexican native, Esperanza (also known as Yellow Bells) is a strong bloomer all summer long. It is outshining the variegated shell ginger interplanted with it.
Well, these Homestead Verbenas are happy, but I have also lost many of them this summer. I planted some in 3 different places at 3 different times since the spring and 6 of them bit the dust. These are well-established and have been in the crushed granite path for at least 3 years. Guess that made all the difference.
Some of the Lantana looked drought tolerant this year and some doesn’t. A few of them never really recovered from last winter’s 19 degrees. They grew some foliage but then just stopped. No more growth and no blooms all summer. Not a one. This “Bandana Cherry Sunrise” is full of blooms.
My photography skills were challenged on this photo — this is Pitcher Sage — a native plant that I got two years ago at the annual Lady Bird Johnson Wildflower Center sale. It is a stunning shade of blue and blooming its head off! In the same bed as the Lantana shown above and the Liatris below, also from the Wildflower Center sale. They share the bed with two salvia greggii. All of these plants are natives, they are in a space where they get less water than most of my other beds, and look great. There’s a lesson there — hope I’m paying attention!

Hope you have lots of blooms in your garden on this Garden Bloggers Bloom Day, hosted each month by Carol of May Dreams Gardens. Happy Bloom Day!
