Centaurea cyanus ‘Black Magic’

This post was published originally on 2007-03-24 and updated with data for 2008 and 2011.
The seed packet from Botanical Interests gives the common name for Centaurea cyanus as bachelor button. For us southerners, bachelor buttons are Gomphrena globosa. Julie at the Human Flower Project recognized it immediately as a cornflower, even though it was not the blue once so commonly identifiable that it is found in a box of Crayola crayons. I was going to go into a rant wondering whether children today connected their crayon colors with real flowers. The truth is, I’ve never seen a living cornflower before I grew this one. And then I chose a selection which is not cornflower blue.

Why don’t I like more cheerful flowers? This cornflower is a deep, plummy purple, a funereal maroon that, in flower marketing, is referred to as black. Morticia Addams would like it–she wouldn’t even have to snip off the flower before creating her bouquet. The plant itself is about two feet high with silvery gray foliage. From a distance, the dark flowers look like furry black caterpillars attacking the plant.

The seed packet said that cornflowers were drought tolerant. However, I’m not sure that translates into heat-tolerant. As soon as the mercury touched 80 today, they drooped. Instructions say to plant them in early spring before the last frost…unless you live in the south, of course! We’re suppose to plant them in late summer or early fall.

I planted these on September 11, 2006 and they just bloomed this week (late March 2007), more than six months later. They sprouted quickly and I transplanted them into the meadow close to the yellow irises thinking that the purple and yellow would make a nice combination. The irises aren’t blooming yet. None of Austin’s mild winter freezes bothered them, not even the ice storm or the night we got down to 25 degrees. They sent up flower spikes about the same time the cilantro did but took a long time to form buds and even a longer time for the buds to open. Every day I looked, expecting to see them open, and every day the flowers remained a tight closed ball. Then I went to New York and when I came back they were blooming. Maybe a watched cornflower never opens.

Dateline: 2007-2008

Discovered some seeds left over from last year and planted them in the west border where I’m clearing out the bearded irises that rotted in this summer’s rains.

2007-12-04.
The cornflowers (I still want to call them bachelor buttons) are about three inches tall and have two sets of true leaves. They are being smothered by competing baby blue eyes, so I dig up the whole bed and replant only the bachelor buttons spacing them about 5 inches apart.

In the mid-70s today and tomorrow. Transplant more bachelor button seedlings. From one group by the agave, three groups: 10 in place, 10 by butterfly bush, and 8 behind maiden grass.

First flower. Even though I planted the bachelor buttons two months later than last year it seemed to make no difference. They bloomed in exactly the same week. I prefer to plant them later if I can because then I don’t have to water as much and besides, I’m always running behind.

I think I will always grow bachelor buttons now because they are so easy and economical, although they did not self-sow. Two years of flowers from a $1.79 packet of seeds is satisfying. The effect is less somber than last year mostly because I have allowed the cilantro to overrun the meadow like a wave of white foam.

Dateline: 2010-2011

Sow half a packet of new seeds. Botanical Interests. 1 gram @ $1.79. Unseasonably warm ahead of a predicted hard freeze. Today’s high: 82°F; low, 70°F.

2011-03-25.
First flower. I never managed to thin these bachelor buttons so the plants are crowded and short. This dry spring has encouraged an abundance of pink evening primroses behind them. This is one of those unplanned combinations that bring delight.

Lupinus texensis
2010-02-02. Bluebonnet seedlings. Given all the rain in central Texas since September, the bluebonnet plants are large and plentiful.

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.
