Trip Report: Zilker Botanical Garden

While we were in Austin we visited Zilker Botanical Garden. There was a special event going on while we were there with local vendors with art, plants, and other things for sale. One of the vendors was a local nursery that had some rare plants for sale, including a small Frankincense tree about 6 inches tall, selling for $250! I talked to the owner and he said that it was a cutting from their parent plant, which isn't very large and that the cuttings are difficult to root. I bought a small Curry Tree for $6 for my friend who had been looking for one of these for years.

Alligator Plant (Acanthus montanus)

We really enjoyed the Hartman Prehistoric Garden, which consists of plants from families that have been on earth for millions of years: cycads, ferns, palms. This garden was inspired by dinosaur tracks and an ancient turtle fossil that were found inside the gardens in 1992. At one spot there are paving stones that are actual ammonite fossils, which is really cool. They also have a bronze dinosaur statue in view across a pond.

The butterfly garden was rather unkempt looking, but the bushy flowering plants were absolutely covered in butterflies enjoying the nectar. I think most of the plants were Blue Mistflower (Conoclinium coelestinum). We saw at least 10 species, likely a few more: Queens, American Snouts, Sachems, Gulf Fritillaries, Red Admirals, Monarchs, Pipevine Swallowtail, White-striped Longtail, Southern Dogface, and a couple of Skippers I didn't identify.

A few other quick things to note:

Coral Fungi, probably from the genus Ramaria

This is not a plant, but I have admired photos of Coral Fungi before but not seen one in person. Along the path in one part of the gardens I noticed a bunch of these on the ground. So beautiful!

A real rock turned into an outdoor light along the pathway

The gardens have these really cool lights along the path. They were not illuminated while we were there visiting in the daytime, but I noticed one when I was bent down inspecting the fungi. They are actual rocks - not those fake plastic ones - that have been cut in half and had lights installed in them. What a cool idea!

Thaumatophyllum bipinnatifidum mislabeled as both a Philodendron (almost right) 

and a Monstera (definitely not right).

It's not unusual to find plants mislabeled in a botanic garden, but it still surprises me every time I see it... In all fairness, this plant used to belong to the genus Philodendron and only recently moved to the new genus of Thaumatophyllum. But still, Monstera deliciosa is a very different plant and in a separate genus.

Trip Report: Treaty Oak

For my birthday weekend my wife and I went down to Austin for a few days sans kiddos. Our itinerary was mostly made up of places to eat and a few activities sprinkled in between. On Sunday morning we visited a famous tree, Treaty Oak, which my wife remembered having visited when she was young. This oak tree is thought to be about 500 years old and is the only member of a group of 14 trees that once stood in this location in what is today downtown Austin. In 1989 someone poisoned the tree and severely damaged it. That is when my wife traveled with her family to see it. Thankfully the tree pulled through and still stands.

The plaque reads:

The Caldwell Treat-Oak Park

Estimated to have been a majestic tree of about 100 years when Columbus first landed on North American shores, this live oak tree has been pronounced the most perfect specimen of a tree in North America, and its picture hangs in the Hall of Fame of Forestry at Washington.

Formerly standing as the center of a group of trees called "The Council Oaks," this tree takes its name from its role in the history of the Lone Star State. Stephen F. Austin is reputed to have signed the first boundary line agreement between Indians and whites under the canopy of its branches; battles and important conferences have been planned, pacts signed, and feasts and religious ceremonies celebrated in its shade.

The Treaty Oak was purchased by the City of Austin in 1937 to stand as a living and fitting symbol of the mighty state it has watched develop.

We were both surprised to see how much of the tree lies on the ground. I don't know if this is characteristic of the species (Texas Live Oak, Quercus fusiformis), or if it has more to do with the vandalism, or the age of this particular tree.

Treaty Oak acorns

While we were visiting the tree I noticed some acorn caps on the branches at eye level and realized there must be some dropped acorns nearby. We searched around and found 5 that were brown and "ripe." I brought these home and soaked them in a bowl of water to see if any floated, which means the acorn is not viable. They all sunk and I decided I would plant them the next day. But I forgot.

More than a week passed before I noticed the bowl of acorns! I was worried at first when I saw they looked different, but on closer inspection I realized they were sprouting. I went ahead and potted the five acorns and watered them well (since they were used to being saturated and seemed happy with the situation). If I am successful I will have some offspring from a famous tree, which is kind of fun. Updates to come!

A tree with a view

My good friend Steve gave me a couple of Paw-Paw trees (Asimina triloba) during the summer. I have kept them in the pot until now, wanting to make sure they were kept watered and healthy during the hot season.

Last week I took them out to my in-law's land where there is plenty of room to plant trees and searched for a good spot. I also had some young Persimmon (Diospyros virginiana) trees to plant. My mother-in-law pointed me an area which already had a cluster of Persimmon trees growing. I don't know if the trees were planted together here many years ago (when my wife's ancestors settled the land), or if they grew here naturally. My mother-in-law had shown these to me in the past but I had never seen any fruit on them. This time around I saw a few fruits up on the tall skinny trees and I saw one smaller, squat tree that was absolutely covered in fruit.

We decided that we would go ahead and plant the Paw-Paw trees here with the Persimmon trees. I like that these little trees have such a nice view. By the way, I took advantage of the loaded Persimmon tree.

Persimmon fruits

Persimmon seeds removed from fruit.
There's actually more seed volume than fruit volume and it was a lot of work to separate the two.

Persimmon cookies

I brought about 30 fruits home and laboriously separated the small amount of fruit from the large amount of skin and seeds and made one batch of Persimmon cookies using the recipe I've shared before. I only got 1/3 cup of persimmon out of the fruits I collected, so I had to modify the recipe. The end result was 14 delicious cookies and 110 seeds that I can now plant. Johnny Appleseed, there's a new seed sower in town.

That time of year...

It's once again that time of year when all of the plants have to be moved back into the greenhouse for a long winter slumber in semi-tropical conditions. Most of my plant collection consists of tropical and semi-tropical plants that can't take the cold Oklahoma winter weather. I keep my greenhouse thermostat at 60 Fahrenheit and it does a pretty good job of maintaining that temperature overnight during the winter, only falling lower when the outside temperature is down in the 20s for multiple hours. Prepping the greenhouse and then moving in all of the winter occupants is a pretty big chore which I knock out in two sessions of about two hours each.

BEFORE: Plumbago (Plumbago auriculata) in all it's glory

My greenhouse is pretty small - especially for the hundreds of potted plants I have. So I have to pack everything in tight, and in vertical layers. Some of the larger plants have to be trimmed back. This year our potted Plumbago really took off and was blooming something fierce last week, when I was moving all of the plants into the greenhouse. I saved it for last and finally took out the shears. After it's haircut it fit into the greenhouse pretty well, leaving just one tiny amount of floor space for me to stand in while I try to water all of the captive plants over the next 5 months.

AFTER: Plumbago (Plumbago auriculata) trimmed back and ready to pack into the greenhouse

Every year I make minor modifications to my greenhouse setup and where I place all of my plants. This year I decided to put my cacti and succulents (which can stay pretty dry over the winter) in the hardest to reach places. I think this will really help because it brings more plants which do need to be watered to more accessible locations and prevents me from accidentally watering something that would prefer to be dry. Also, some of those hard to reach places receive a little more light than other places and the cacti and succulents will like that. In previous years I had put my Plumeria plants on one of these high, sunny shelves. Since they drop their leaves over the dry winter, they really don't need to be in sunlight, so I have those scattered around in various places in the greenhouse this year.

Cactus rot

It has been a wetter than normal year in most of Oklahoma. My sister just got interested in succulents and cacti recently and has some of her plants out on her front porch for the warm season. When I was at her house a few weeks ago she pointed out one of her new cacti that was in bad shape. I'm afraid this plant was getting a lot of runoff from her roof and was just too wet. She mentioned it was actually her favorite and she was hoping it wasn't a goner.

The central growth had rotted and was just a black mushy clump with spines. However, it looked like there may be some salvageable growth that had not begun to rot - yet.

I gave my sister some instructions on what to do and then asked if she'd like me to do it. She was happy to hand it over. I took it home, donned some gloves, and carefully unpotted it. I separated the healthy green growth from the black mush and threw that away. I was going to set the green growth aside to let it callous before planting it again, but it seems to be without wounds and had roots attached, so I carefully repotted those growths. Important: I did not water the pot and I sat it aside in the greenhouse in a location where it will stay dry.

I will check this pot regularly over the next several weeks and hopefully not see any new rotting. Assuming all is well, I'll add some rocks to the surface of the soil again and take it back to my sister.

The Mighty Plumbago

I first became familiar with Plumbago (Plumbago auriculata) several years ago when we were planning our Galveston garden. This is a pretty popular garden plant in that area. It grows into a pretty big bush with time and will be covered in pale periwinkle blue flowers during much of the year (in warm climates).

Plumbago auriculata

We planted one in Galveston and it grew quite large - prior to the brutal winter, which killed it. We have since replaced that bush with a tiny starter, which I expect will take a year or two before it is dominating it's area of the flowerbed.

Plumbago auriculata

This has become my wife's favorite plant. A couple of years ago we ran across a Plumbago in a nice black square pot at a nursery in Oklahoma and decided to get one for our house, even though it's not hardy. We keep the plant in my greenhouse overwinter and it usually looks pretty rough in the spring when we pull it back outside, but it grows pretty quickly and flowers vigorously in the summer. It is putting on quite the show right now. Soon I will have to prune it back and squeeze it into my greenhouse for the cold winter months.

Plant Find: Begonia sizemoreae

The title of this post is a bit misleading. I didn't find this plant; it was given to me by my friend Steve. I use the "Plant Find" heading for new plants coming into my collection, regardless of how I obtained them. Steve tells me that it roots very easily from leaf cuttings and he has had to start tossing his cuttings now because he has so much of this plant.

Begonia sizemoreae

Begonia sizemoreae is native to Vietnam and likes humidity. It has been enjoying our wet summer. The leaves and petioles are covered in long bristly hairs.

Begonia sizemoreae

This beautifully patterned Begonia is named after an avid collector named Mary Sizemore. She is well known among Begonia aficionados.

Update: Sacred Bodhi Tree

Seven years ago I was gifted some seedling Sacred Bodhi trees (Ficus religiosa) from a friend. Read more about the tree here. I gave one of those seedlings to my mother-in-law for insurance. I'm glad I did because my tree died a couple of years ago when it got too dry in my greenhouse. My mother-in-law's tree goes through a series of phases: rapid growth, scale infestation, dropping all the leaves - repeat. We're not sure why the scale keeps coming back, as it seems completely free of them when it is in it's rapid growth phase. Anyway, it seems to be an established pattern now.

Sacred Bodhi Tree sapling (Ficus religiosa)

I recently took two cuttings of her tree when it was in a rapid growth phase and one of those cuttings has rooted. I started the cutting in pure vermiculite. After I was sure that roots were established I transferred it to potting soil. It's now producing new leaves and seems to be pretty happy. In a humid tropical climate this tree would easily be meters tall by now, but in our temperate Oklahoma climate (and my mother-in-law's plant being grown indoors) it is staying fairly small, almost a bonsai. I'm so thankful to have this little tree back in my collection and will monitor it closely.

A couple Huernia blooms

Without a doubt, Huernia is my favorite succulent genus. This genus is in the Stapeliaceae family, closely related to the common carrion flower/starfish plant, Stapelia gigantea. I have amassed a pretty good collection of these plants and always seek them out at the Central Oklahoma Cacti and Succulent Show. This year I purchased a new one that was labeled Huernia sp. The petals of the flower reflex after a day or two, resulting in a different appearance (shown in second photo).

It bloomed not long after the show and I was able to get some help identifying it as either Huernia procumbens or a hybrid of that species.

Another Huernia that I picked up recently is Huernia zebrina, which has very distinct yellow and red flowers. This plant is sometimes called the Lifesaver Plant, due to the red ring that forms in the center of the flower, similar to the plant above, but more pronounced and much more colorful. I was delighted when the first flower opened on my plant and have been pleasantly surprised to see this plant flower constantly all summer for me. There have been as many as 5 flowers open on the plant at one time.

Year of Encyclia

2018 has been a banner year for my Encyclia collection. I have never had so many species bloom before. I just wanted to post a bunch of photos of their beautiful flowers here together to share the variety.

In all, I had at least 16 Encyclia plants bloom this year, as well as about 8 other orchids.

• Encyclia alata (syn. belizensis)
• Encyclia angustiloba
• Encyclia atrorubens
• Encyclia 'Belize 82'
• Encyclia hanburyi
• Encyclia phoenicea
• Encyclia plicata
• Encyclia ramonense
• Encyclia seidelii
• Encyclia tampensis
• Encyclia tampensis v. alba
• Encyclia unaensis
• Encyclia Faerie Glen
• Encyclia Gay Rabbit
• Encyclia Grand Bahama
• Encyclia Orchid Jungle

Butterfly Vine from seed

I have long-since admired a particular plant growing in the Butterfly Garden on the bay side of Moody Gardens in Galveston. I'm actually amazed that I've never blogged about it before. This plant is a creeping and mounding vine, and I suppose it would climb if it had something to climb. In the summer it produces many small yellow flowers in clusters.

After those flowers are pollinated the seed pods form and things start getting interesting. The seed pods begin green and sort of blend in with the foliage, but they have a very interesting shape. Like many other seeds they have wings that help them disperse in the wind. It just so happens that these wings make them look a lot like butterflies. As the season progresses the seed pods dry out and become a more conspicuous brown. I collected some of these seed pods a few years ago and my mother-in-law was using them as decorations.

This summer I decided to dissect a few of these to get to the seeds. The seeds are smaller than I was expecting. I planted them in some moist soil and let time do its thing. Just a few of these germinated for me, not surprising considering the amount of time since they had been harvested. I planted one of these along the fence line at the house in Galveston and I'm hoping it will do well there without any special care. I have kept the other one at home, in a community pot with other seedlings I started this summer. It is slow growing so far. Perhaps I need to provide more sunlight.

I found a story from Birds & Blooms magazine about a woman who painted the seed pods as real butterflies. Pretty neat.
