GBBD 201104: Apr 2011

Carol at May Dreams Gardens invites us to tell her what’s blooming in our gardens on the 15th of each month.

April 2011

The drought continues. The pink evening primrose and Engelmann daisy seem to prefer this drier weather and are the stars of the day. The dry weather hurries summer along. Many flowers that are usually in bloom in April have already finished. Others that don’t usually start blooming until later have already begun. Even semi-weedy plants like baby blue eyes are relatively sparse and the plants are tiny and shrivelled. Austin’s ubiquitous bluebonnets are short and faded.

My larkspur plans have gone awry. I dug two beds along the front path several years ago. Larkspur was supposed to line the path and the lawn. The lawn died. I didn’t get the larkspur planted this year. The last two years it self sowed where the lawn was. This year I didn’t get my beds planted so the self-sown larkspur is all I have. Without water or thinning the resultant plants are only about one to two feet tall rather than three or four feet tall. The front yard now looks a bit like the back yard used to. The meadow in the back yard is almost completely devoid of larkspur. After ten years, what was once the meadow is almost completely in shade by the time the wildflowers want to bloom.

Between GBBDs

Flowers that bloomed between March 15, 2011 and April 15, 2011 and so did not appear in either list.

  • Allium neapolitanum
    These use to flower in abundance in the meadow but creeping shade and this year’s drought resulted in only one bulb blooming.
  • Datura inoxia
    One flush of flowers already, just none open today.

Setsubun, Halfway Through the Season

Dateline: February 2, 2008

Anemone coronaria
The Anemone coronaria has sprouted adding to my anticipation of spring. This is the first year I’ve grown them.

In the days when people spent more time observing nature than television, this week marks a significant moment in the year, halfway between the winter solstice and the spring equinox. Many cultures celebrate this turning point in winter as the beginning of the new year, the beginning of spring, even though for many the worst of winter is yet to come. For Christians, the end of the Christmas Season and the liturgical year is celebrated at Candlemas. Americans try to forecast the weather on Groundhog Day. The Chinese New Year (based on a combination of solar and lunar calendars) begins. And the Japanese celebrate setsubun, literally halving the season, driving evil spirits from their house while inviting good ones to stay on the eve of spring.

Anticipation of spring is running high here at Zanthan Gardens. The Spanish bluebells, Hyacinthoides hispanica, are nosing up. Spanish bluebells
I planted them to remind AJM of home. Traditionally the English have used Spanish bluebells in their gardens because they are larger than the native English bluebells of the woods. However, recent worries about non-native plants have created controversy over Spanish bluebells. I’m surprised they do so well in Texas. They’ve come back every year neither increasing much nor diminishing.

I was very excited to step out into the garden after a few cold wintry days and see the Tulipa clusiana. I was afraid that with all of the rain last summer that these species tulips had finally rotted away.Tulipa clusiana
Tulipa clusiana likes hot baking summers and doesn’t require any chilling period to bloom. As such, it is the ideal tulip for Austin, where most tulips are difficult to naturalize.

I worried that last summer’s rain might have also done in the delicate triandrus daffodil “Hawera”. This is one of the few daffodils I’ve grown which has come back reliably over many many years and flowers without any chilling.
Narcissus triandrus Hawera

Like Yolanda Elizabet at Bliss, I’m excited to see the summer snowflakes coming up. Unlike many bulbs, they don’t mind Austin’s clay soil.
Leucojum aestivum

The overwintering annuals have put on lots of growth–or at least the ones that I managed to thin and replant during December have. Batchelor buttons

This is the second year I’ve grown bachelor buttons, Centaurea cyanus. In fact, these plants are from the seeds I had leftover from last year’s seed packet. I’m so pleased with their perfomance (and how easy they are to grow) that they have one a place in my permanent repertoire. Behind the bachelor buttons in this photo are the baby blue eyes, Nemophila insignis, which desperately need to be thinned.

This weekend promises to be beautiful, sunny and in the 70s. I have loads of pruning, weeding, and transplanting to do (and watering because it’s been so dry). What joy it will be to be out in the garden, though, checking over all the plants just waiting to burst forth in bloom.

Update: February 2, 2010

In some ways, Spring 2010 couldn’t be more different than Spring 2008. Then we were at the beginning of the drought and now we’ve had 5 months of cool, rainy weather and a killer freeze. All the overwintering annuals are large and plentiful and trying to bloom well ahead of schedule. Because this winter has been cloudier and cooler, this copious tender growth keeps getting nipped back by weekly freezes.

The Anemone coronaria did not survive the drought. Nor did my narcissus. But the Tulipa clusiana, Spanish bluebells, and Leucojum aestivum carry on rain or shine.

Consoloda ambigua
2010-02-02. Larkspur buds. The larkspur, which are usually in full bloom in April, keep sending up flower stalks that are cut down with each freeze.

While the rainy weather has allowed the self-sown annuals (including weeds) to proliferate, it has kept me from most of my gardening chores. I haven’t even sown many new packets of seeds such as the bachelor buttons yet. I have a short window of opportunity in which to sow seeds around Christmas after the leaves fall. If the weather is not encouraging or I’m too busy with the holidays, then I miss my chance before the heat sets in. Not that I won’t try anyway. This year might be a long cold spring letting us have flowers into May. Well, we can dream.

GBBD 200705: May 2007

Carol at May Dreams Gardens invites us to tell her what’s blooming in our gardens on the 15th of each month.

Despite the list of flowers, the garden is mostly green this time of year. A lot less is flowering than in April. The only flowers in any number today are the rose ‘Red Cascade’, two different four o’clocks, batchelor buttons, clammy weed and some larkspur. Everything else has just a flower or two, fading under the last few day’s 90 degree temperatures. All I’m doing in the garden now is pulling out spent flowers and digging up bulbs.

May 15, 2007

This is the fourth day of temperatures hitting 90 degrees–and the spring flowers are drying up and falling over.

  • Centaurea cyanus ‘Black Magic
  • chili pequin
  • Commelinantia anomala (false day flower)

May 6th, 2007
Week 18: 4/30 – 5/6

Dateline: 2008

The last reprieve before summer. When Vertie and I went to get the glass mulch on Friday (5/2), it was a hot 88F and muggy. Saturday was dry and cooler by 10 degrees. The lows over the weekend seemed comparatively chilly at 59F. Big storms for Monday and Tuesday didn’t pan out which means will be facing temperatures in the 90s next week without a reserve of rain.

This is confederate jasmine week. It has been in full bloom for the last couple of weeks everywhere…a really good year for confederate jasmine. My sweet peas are also finally blooming. Caterpillars ate all the buds right before they were going to flower and it’s taken them a couple of weeks to put out more.

The ‘Mermaid’, ‘Red Cascade’ and ‘New Dawn’ roses have all been blooming very well. ‘Blush Noisette’ is trying but is balling terribly this year. ‘Ducher’, ‘Prosperity’, and ‘Souvenir de la Malmaison’ are still putting out a flower or two. I did lose the ‘Penelope’ rose that had me worried this time last year.

The California poppies surprised me with a second flush of flowers. The others are finally blooming, a month behind everyone else’s in Austin. In a way it’s nice because they fill in the spots left empty by the larkspur and cilantro. Speaking of which, I decided to fill in empty spaces in the meadow with bought pepper and tomato plants. The problem is remembering to water them regularly when they’re scattered all over the yard. The pink evening primrose and Engelmann daisy are still flowering well.

Getting busy gathering seeds of larkspur, bluebonnets, and cilantro.

First flower: Nigella damascena ‘Mulberry Rose’ (4/30); bearded iris ‘Silverado’ (5/1); white mistflower (5/4); Dolichos lablab (5/5); summer squash (5/5).

Dateline: 2007


Zanthan Gardens
2007-05-06. 2007-05-06. Rather than a pretty flower photo I thought I’d focus on the most memorable sight in the garden at the moment: the old shed in rubble and larkspur blooming in the meadow to the north.

Spring Fling is over and, May, the month of green is upon us. That’s how I think of May. This is a transitional week, a transitional month. Most of my flower spectacle is over until fall. I put all my effort into early flowering plants because once my trees leaf out there isn’t enough sun for the warm weather flowers. I’ve had to learn to stop envying other Austinites’ vitex, lantana, butterfly bushes, and salvias. Besides when the weather turns muggy, I can’t stand the press of all those plants that make March and April shine. I just want to clear everything away.

May is typically one of Austin’s rainiest month. We’ve had almost two inches just this week as thunderstorms keep rolling through. On top of that, we’ve more than average rain this year since the middle of March. May is living up to its lush green promise. We expected the cloud cover to burn off this week and the temperatures to hit 90. Instead it remained drizzly and in the low 80s all week. And a bit muggy! The 90% humidity makes it as steamy as a jungle. A mustiness pervades my house and there are small snails on every plant. The mosquitoes and the cockroaches have decided summer is here. And I heard the toad last night. That makes it official.

The ‘New Dawn’ and ‘Blush Noisette’ roses have bowed out and now ‘Mermaid’ and ‘Red Cascade’ are in full bloom. I’m worried about ‘Penelope’. She was covered in flowers last month and suddenly all the leaves turned yellow. Is she going to succumb to dieback like ‘Buff Beauty’ and ‘Madame Joseph Schwartz’?

First flower: chili pequin (5/2); Hibiscus syriacus (5/3); Abelia grandiflora (5/4); Cosmos bipinnatus (5/5) one self-sown.

Dateline: 2006

Rain, rain, and more rain. I’m still looking for the official rainfall totals but it seems south Austin got about half an inch on Tuesday, 3 inches on Thursday, 2 inches Friday, 2 inches Saturday, and possible another inch Sunday. I wish I had about 50 more rainbarrels.

The spring flowers (bluebonnets, larkspur, evening primrose) are going to seed. The roses, except for a flower here and there, may be finished until fall. The irises were noticably absent this spring. Now the flowering perennials (esperanza, four-o’clocks, crape myrtle, oleander, rose of Sharon, red yucca, various salvias, and plumbago) are moving into the spotlight. Even so, with all this rain, the overwhelming impression of the garden this week is green.

There was a time when I first began gardening that I said all that these desert-bred eyes craved for in a garden was a green shade. Now I’m less easily satisfied.

First flower: Mirabilis jalapa, RHS red (5/1); plumbago (5/4); crape myrtle ‘Catawba’ (5/5).

Dateline: 2004

Following killer-flood rains last Saturday, the week opened with two perfect days. The nights were cool, the temperatures tying with record lows set 50 years ago. And the days were dry with brilliant blue skies usually seen only in the fall.

My neighbors behind me cut down a huge oak tree that had its top sheared of. in a storm seven years ago (but was still growing strong). They also removed a hackberry and other brush along our fence line. Now, what had been my shade garden, is in full afternoon sun. 2007-05-06. Note: They’ve planted a butterfly rose over the fence and some other plants. I think they have a landscaping service or something because it looks like a nursery back there.

2004-05-06. What remains of my neighbor’s tree. Bill might notice that the bindweed is quite rampant.

First flower: rose ‘Red Cascade’ (5/3); first cherry tomato (5/5); rose “Caldwell Pink” (5/5).

Rebloom: rose ‘Souvenir de la Malmaison’ (5/7); rose ‘Madame Alfred Carriere’ (5/8).

Dateline: 2002


In my garden, March is wildflower month, April is iris month, and May is the month of green. The spring flowers are cleared away and the trees and grass have deepened into a rich green. This is the one month where it summer looks pleasant, before the heat and drought of real summer turns everything brown and dusty.

We began this week with a momentary break in the heat. A front came in on the 3rd and cooled temperatures down by at least ten degrees. So I spent all Friday morning reading in the garden in my new Adirondack chair…a very Martha Stewart moment. It didn’t last long enough. Very quickly we returned to hot, humid weather.

The bad news this year is the lack of rain. May is supposed to be one of our rainiest months. We are already behind for the year and it doesn’t look like any relief is on the way. The worst part of this heat is the realization that although 90 feels hot now, sometime in August, 90 will feel cool. When it’s 90 in August, you know Fall is on the way.

On the plus side, the cannas and banana are taking off. And we ate the first cherry tomatoes this week. The black-eyed Susans are blooming. And there are still plenty of larkspur to attract the butterflies. A stray bluebonnet still blooms, where I’ve watered and dead-headed them. And the last iris, ‘Silverado’ bloomed. Clammy-weed is popping up everywhere, a nice bright green. It grows to almost two feet in the garden beds where it gets water. In the meadow, though, it is much shorter.

The confederate jasmine is in full bloom. I love its glossy, deep green leaves and thickly sweet scent. I rooted a runner last year and transplanted it this spring and it’s blooming, too. The lavender I rooted is also blooming. It’s a good thing I’m having some luck with rooting and divisions because my attempts to grow things from seed have not been very successful this year. Although a couple of things have popped up from seeds I planted last year. One is an Apple of Peru. I don’t know what the other one is. Maybe cuphea. Maybe some new weed.

The violas, sweet peas, and columbines have succumbed to the heat. The Dianthus chinensis is looking a little seedy, but what amazes me is that this is their second year. They are usually considered only winter annuals. [Note: These plants persisted in the garden until 2005 when they finally succumbed to the drought.]

Plant Profile: Consolida ambigua (annual larkspur)

January 10th, 2002
Consolida ambigua

I’ve spent the last couple of days weeding some beds and transplanting the self-sown larkspur in them. The larkspur plants are about 4 inches tall. I’ve read in several places that they are difficult to transplant but I have never found that to be true. They do have a long tap root, so you have to be careful when digging them out. They don’t come up in bare earth; they seem to prefer the mulched paths and beds. This habit suits me as it is easier to clear out a bed, add some wood ash and superphosphate and then replant them about eight inches apart than it is to let them seed in place and then thin them. And if you want them to grow to any decent height, you have to thin them.
