The Trees that Grow in my Garden

A few days ago fellow Central Texas garden blogger Laura at Wills Family Acres wrote about the trees growing on her 2-acre property. It was fascinating to see the large numbers of live oaks and cedars on her plot, and also fun to see how many trees she and her family had planted.

I really liked the idea, and decided to copy Laura and make my own Tree Inventory post. After subtracting the area covered by driveway, hardscape & house from my quarter acre lot the remaining plantable area is pretty small... how hard could it be to count the trees on 1/8 of an acre?


"This should be a cinch," I thought. "All I have to do is take the tree names from my plant spreadsheet."

But it wasn't that that simple. The first problem was deciding what counted as a tree. Are hollies trees or shrubs? Are boxwoods shrubs? Where are the lines?
What about small baby trees in growing-on containers?  Do I count trees that are brought into the garage or house in cold weather?

The second problem was that my spreadsheet was not complete. I'd made a note of every tiny plant brought home from Barton Springs Nursery and the Natural Gardener, but had never entered some of the large boring plants already growing here in 2004 when we bought this house. (I'm talking about you, Photinia.)

Categories seemed to be the answer.

For this list, a baby tree in a container is still a tree and trees kept permanently in containers are still trees, but they'll have their own category. I considered calling this Texas Palmetto a tree, but with a future height of only 5 to 6-ft, decided to leave it off the list.



A plant that wants to be a tree but can be kept to shrub height by constant pruning counts as a tree on the list. Neglect to prune a Ligustrum hedge or a Red Tip Photinia hedge and you'll end up with a forest of Ligustrum and Photinia trees.

If a treelike plant has the potential to be 7 or 8 feet tall it counts as a tree. For example, my Barbados Cherries have been pretty wimpy, but I've seen them look like small trees in the gardens of friends. 

The trees and treelike shrubs that were already growing here when we moved in will have a separate category.


GROUP 1 -Trees that were here when we moved in that are still alive :

Arizona ash (1 very large)

Pecan, unknown variety (2 very large)



Live Oaks (2 medium large)

Yaupon holly (1 lovely, muli-trunked tree, about 15-ft  tall)

Crepe myrtle, the common hot pink ( 6 in sizes from 7-ft to 20-ft)

Holly - some kind of Chinese holly (1 allowed to be a 12-ft tree, 1 pruned repeatedly to 5-ft)

Nandina (3 kept at 6-ft)

Red tip Photinia (3 kept under 10-ft)



GROUP 2 - Trees that were planted by us:

Loquat tree (3 trees, one large, one medium, one about 4-ft tall, all from seedlings)


The largest loquat is in the photo above, with Bay Laurel in container left, larger Southern Wax Myrtle in ground right

Magnolia 'Little Gem' (1 about 12-ft tall)

Sweet Olive (3. The oldest is very established and kept to 12-ft tall. Two younger plants are under 5-ft.)

Texas redbud (1, about 10-ft tall)

'Forest Pansy' redbud (1, about 10-ft tall)

Vitex /Chaste tree (1, kept to 10-ft tall, from a seedling)

Magnolia figo/ Banana shrub (1 about 8-ft tall)


In the photo above, the Banana shrub is at left next to the bench, center is a young Texas Mountain Laurel, then a camellia, then the tall, burgundy-leaved Loropetalum/Chinese Witch Hazel


Cenizo/Texas sage (1, kept to 8-ft, grown from a seedling)

Beautyberry AKA French mulberry (1, kept to about 7-ft tall)

Evergreen sumac (1, barely 5-ft tall after 7 years in the ground)

Barbados cherry trees (usually frozen back, one tree about 6-ft, another about 4-ft)

Crepe Myrtle 'Acoma' blooms white (2 trees, called semi-dwarf, kept to abt 12-ft in height)

Crepe Myrtle 'Catawba' blooms purple (2 young trees, under 5-ft.)


Crepe Myrtle  labeled 'Muskogee', supposed to bloom lavender (1 young tree, abt 6-ft tall)

Crepe Myrtle 'Zuni' blooms orchid pink (1 young tree, under 9-ft)

Meyer's Improved Lemon (1 tree, when not winter-killed, pruned to about 9-ft tall



Loropetalum/Chinese Witch hazel (2 - the one in photo with Magnolia Figo is about 9-ft tall, the other is a young plant about 2-ft tall.)

Pineapple guava (1 about 6-ft tall)

The Pineapple Guava has reached the top of the privacy fence - in the background is one of the Live Oak trees.


Rose 'Mutabilis' (1 in ground, kept to 8-ft by diligent pruning)

Texas Mountain Laurel (4 plants. Two about 6-ft, one about 5-ft, one about 2-ft)

This is the only one of my 4 Texas Mountain Laurels that has ever bloomed.

Satsuma orange 'Miho' (1 young tree abt 3-ft tall)

Southern Wax Myrtle (1, about 5-6 ft)

Mexican Buckeye (1 baby tree in the ground, maybe 2 and 1/2 ft tall)



GROUP 3- Trees planted by us, presently growing in containers:

Oleander (1, very large container, kept to 10-ft in height.)

Rose 'Mutabilis' (1 about 6-ft tall)

Bay Laurel (1 about 5-ft tall)

Southern Wax Myrtle (1 abt 4-ft tall)



Dwarf Pomegranate (2 plants, one under 2-ft, one about 7-ft tall)

Pineapple guava (1 about 5-ft tall)

Montezuma cypress (1 baby tree)

Thai lime trees (2 small trees, both under 3-ft, one in garage, one outside)

Willow, corkscrew (1 under 5-ft kept in container, grown from a cutting)

Meyer's Improved Lemon, (1 small tree bought in March 2006 - blooming in the breakfast room right now)




Whether or not this list is interesting to you readers, it sure is useful for me as a garden record... Thanks for the idea, Laura!

Blue Clerodendons & Pecans for November GBBD

         This post was written by Annie in Austin for her Transplantable Rose blog.

Our Austin gardens have flirted with Jack Frost a few times, in the hours just before dawn on clear dark nights, but Mr. Frost has not yet done the deed. The Forsythia Sage/Salvia madrensis still spreads her blossoms unmolested in the big front bed.


One Blue Butterfly Clerodendron cavorted with a Mutabilis rose a few weeks ago but their romance faded as the sun's angle changed and the shade from our two pecan trees deepened.



The rose stopped blooming and the Blue Butterflies float alone now. After the leaves fall the strong winter sun may tempt the rose to bloom again, but the clerodendron plant will die down once the temperatures drop below 30°F.

The pecan trees dominate the back garden year round, casting light shade when leafless, so we can grow a spring vegetable garden, but in late fall their shade is at its heaviest, casting a gothic gloom over the south end of the yard.





I first sang to the trees in public in March 2007 when the demise of an Arizona Ash called for a music video. That was nearly six years ago! The pecans are even more important in our little garden world so they should have a turn, too. Last weekend my husband Philo and I turned my "For A Tree That Keeps On Giving, Plant Pecan!" song into a music video, intended to amuse anyone who has ever lived with a very large, very messy tree:






I hope you'll soon be singing along ..."for a Tree that keeps on giving "Plant Pecan!"
A collection of our garden songs and videos are at our Roots in Austin YouTube station


Since so many of the plants in bloom right now are the same flowers that have been in bloom for months, they'll go in a Garden Bloggers Bloom Day List (with more photos and my best shot at the botanical names) over on my companion blog Annie's Addendum That way the rest of this page can be filled with photos of the Blue Butterflies still whirling while old Jack F. lurks in the shadows with his ice-crystal knife.


I'm not sure what name will on the tag if you buy this plant in a nursery... it could say Blue Butterfly Clerodendron or Blue Cat Whiskers, Clerodendrum ugandense, Clerodendrum myricoides 'Ugandense' or perhaps Rotheca myricoides 'Ugandense'. The zone 9 plant is marginally hardy here in Austin - a couple of my plants have lived through winters with temperatures around 18°F, but even with heavy mulching they died back hard and were slow to recover the next spring. I've tried to hedge my bets by keeping at least one plant in a container in the garage over winter.

Here's the plant that was in the garage last year, now on the patio





The Blue Butterfly plant is so lovely that I wanted more! I've had some luck getting cuttings to root in potting soil lightened by the addition of perlite. (Don't be shocked when the not-lovely scent of the cut or crushed foliage reaches your nose... it stinks!) Some of the cuttings failed but a few plants made it. They were very slow to get going, but two were finally robust enough to go to friends this spring. A third was planted here near the Meyer's lemon on the back housewall. This bed is my magic spot, with a faucet nearby, the area bathed in morning sun but protected from hot west sun and north winds, the soil regularly composted and the plants tenderly mulched. No wonder the Clerodendron is More than Happy!





Since the winter months of January and February 2012 were relatively mild, the original passalong plant from my friend Ellen had an early start in the triangle bed. Now it's more than 5-feet tall and still blooming, with wide spread branches. I took this photo this afternoon and decided to make it into a poster.






Happy Garden Blogger's Bloom Day from Annie & Philo in Austin! Please visit Carol at May Dreams Gardens to see her roundup of garden bloom posts from all over the world.

The Shadiest Time of the Year

This is our fifth autumn in this house and as each October ends we've noticed that the air-conditioner seldom kicks on no matter how warm the day. The sun is so low that it can't penetrate the still-full, green canopy of the two tall pecan trees to heat the rooms on that end of the house. The east end of the garden gets sun in the morning, but by the middle of the day the back garden is all shadows. As the sun swings around to the west around 3 PM, it illuminates the outside edge of the garden along the fence and then shines on the vegetable patch. Spanish Spice peppersAfter barely surviving the long hot summer, the pepper plants obey their biological imperative, using the sun at low power to reproduce and set a couple of dozen peppers. We'll let the peppers run their race to grow until the freeze warning comes - and will be glad to have even a small crop!

In late afternoon enough sun falls on the Secret Garden to trigger a few Confederate Rose blooms. Hibiscus mutabilis is a close relative of hardy Hibiscus like my 'Blue River II'. Hibiscus mutabilis, Confederate RoseConfederate Rose can grow to tree size in Austin if sited well, but my small plant is new this year - a passalong from my friend Carole, it's still in a 10" container.


Camellia sasanqua 'Shishi Gashira' Enough sun fell through the pecan leaves to set buds on the Camellia sasanqua 'Shishi Gashira' a few months ago. The taller, older Camellia japonica did not enjoy this summer. It looks stressed and may have a handful of flowers this winter. In contrast this little sasanqua didn't seem to suffer one bit and is prepared to open dozens of blossoms.


When I wrote about berries in October I had to leave out the most spectacular berry in our yard - a tall Yaupon near the gate. The paperbark type of birch tree was always something I admired for decades but could never own. They didn't do well in Illinois and could not survive here. Now the sight of bright berries, beautiful trunks and white bark have vanquished any longing for birches... I love my yaupon!



Brugmansia buds in progressThe morning sun is enough to make these Brugmansia set buds but they develop more slowly than they did a month ago. If frost comes too soon these buds will never become yellow trumpets and the peppers and warm weather annuals will die and these passionvines will turn to threads, but the garden won't go to sleep.



Instead, as the pecans let loose their leaves, the winter sun will shine through the spaces between the bare branches.
Loquat Tree in BloomWhen the shadows turn again to sun it will be time to plant pansies and snapdragons, alyssum and dianthus. The loquat will keep opening fragrant flowers and when we take our coffee out to the patio, we'll be glad to have the patio umbrella over our heads.

The Old Dogs Learn Something New

This post, "The Old Dogs Learn Something New", was written for my blogspot blog called The Transplantable Rose by Annie in Austin.


Philo and I were invited to a pig roast on Saturday afternoon. As I gathered ingredients for corn bread and some Meyer's Lemon/Cranberry relish that morning, Tom Spencer's garden radio show played in the background. Tom's answer to one caller sent me running down the hall to the office - Philo had to hear about this! A woman wondered whether she should put the shells from her pecans into the compost or use them as mulch - and she was told it might not be such a good idea... while pecans are not as allelopathic [not alleopathic*] as Genie's infamous Black Walnut, they do contain juglone, a substance that can prevent the healthy growth of certain other plants.


With that large canopy of pecan trees hanging over our garden and the ground covered with husks and shells discarded by the squirrels, how concerned should we be? Was this the reason our tomato plants grew well the first summer, but seemed progressively more spindly the last two seasons?

We'd heard for decades that some plants, including tomatoes, wouldn't grow under Black Walnut trees- friends in Illinois had that experience - but we hadn't realized Pecans also had some juglone. The two of us started searching and reading, finding references to
Black Walnuts, Pecans, Allelopathy and juglone in many articles, advice columns, forums, sites from universities and extension sites. As always, clip-and-paste ran rampant, with many sites using exactly the same wording and the authors disagreeing completely on the toxicity.

The conflicting articles stated that the leaves had juglone but the shells did not; that the juglone was concentrated in shells and bark; that it could persist for a long time or that a few weeks of composting eliminated it; that there was enough juglone in pecans to stop the growth of tomatoes or that the amount was so minimal it didn't count. Whether the soil was sandy or clay seemed to make a difference, as did the amount of moisture. Some sources recommended that adding lots of compost and improving drainage could remedy an area with high amounts of juglone. We read that juglone from black walnuts is used in traditional medicine to heal ringworm in humans and also read that allelopathy* swings both ways - the Department of Horticulture at Oklahoma State in Stillwater found that bermuda grass may inhibit the growth of pecan trees.

When I browsed a Project Gutenberg book called Growing Nuts in the North by Carl Weschke, one chapter told of the author's experiments in the early 1920's. It was pretty funny to hear him call the pesky squirrels "bushy-tailed rats" - that was definitely a bonding moment with someone from the past.


Our tentative conclusion after a couple of hours research was that for most areas of the garden, any juglone found in the pecan tree did not seem to have done any harm. On the other hand, it had probably been a mistake to incorporate such large amounts of pecan leaves into the tomato & pepper garden over the last 3 years and the waterlogged conditions of early summer may have intensified the effect.

Although our conclusions are tentative, we've noticed that several other plants in the nightshade family declined when in the root zone of the pecans - the Brugmansia got smaller instead of larger and only grew when moved to the far side of the garden. So to be on the safe side, we'll keep the pecan leaves, twigs and hulls out of the vegetable garden and not use them anywhere unless they've composted for a year. We'll add different compost to the tomato bed in spring, perhaps treating it with liquid compost now. A few weeks ago I transplanted that Solanum in the photo above to the triangle bed. It's one of the ornamental potato flowers but it wasn't growing or flowering. Now I realize this member of the nightshade family was also under the drip line of the pecan. Was that a factor in its failure to thrive?

This is more than you wanted to know about juglone, isn't it! If a pecan appears here again, I promise it will be in a pie! Let's move on to flower photos.


There were a few openings since the blooms were posted on the 15th - here's the peach iris unfolded. It sure looks odd backed by blue Plumbago, lemons, a 9-foot Brugmansia and the pink cuphea in bloom!


The Sasanqua camellia 'Shishi Gashira' opened a few flowers yesterday, but a fast moving gust of rain and wind shattered the flowers. More buds await their turn.


The next flower is difficult to photograph - a polaroid filter held over the lens helped a little.
That white line is the odd flower of a plant called Hoja santa, or Piper auritum, with large aromatic leaves that are used in Central Mexican cuisine. We once tried them parboiled and cut into squares, then filled with a chicken, pepper and rice mixture before folding into packets and baking.


Austin garden photographer Valerie was the person who first introduced me to Hoja santa - she has more information on the plant.


A cold front with rain is expected tomorrow evening followed by a weekend of cold, wet weather with highs in the fifties and lows in the upper-thirties. [from 10 degrees down to 2 degrees for you who use Celsius].
But today I can still admire a gulf fritillary on the pink cuphea.

Today I can enjoy the red berries on the Yaupon holly as it arches across from the left side of the path to the gate, mingling with the sharp and pointed leaves of the holly tree growing next to the garage.

Happy Thanksgiving to all of you from Philo and Annie in our garden in Austin, Texas.

*Edited Nov 26 - my son pointed out that the words are allelopathic not alleopathic, and allelopathy not alleopathy. Thanks, kiddo - still learning .... Arf, arf.
