Keeping Up with Snails


An old garden pest puts a dent in what has been predicted to be a banner year for wildflowers.

The glory days of March in Texas are nigh. After an unrelenting drought, good rains late last year and intermittent downpours over the past two months have the wildflower swamis grinning in expectation.

So were we until about a week ago, when we saw that a once-lush patch of bluebonnet plants along the front slope was taking a beating. The leaves were mangled and bitten off. Trampled by pigmy goats?

No. Along the central stalk of two big Agave americanas and deep into a razor sharp sotol, we spotted snails, scores of them, tucked away for the afternoon.

Flowers of Resolution, Christchurch


How do secular societies face a common tragedy? Christchurch, New Zealand, devises a public ceremony, with flowers.

“River of Flowers”

Map: Healthy Christchurch

Today Christchurch, New Zealand, marks one year since the deadly earthquake that killed 185 people. A community health group polled the residents to ask how the disaster should be commemorated.

Cantabrians expected another huge gathering a Hagley Park, where a memorial had taken place several weeks after the tragedy. Yet, many residents also wanted to gather in their respective neighborhoods, “to allow communities to be together to commemorate, and to look to the future.” Human lives had been lost, and so were many of the city’s buildings. 100,000 houses were damaged, and 10,000 were entirely demolished either by the quake itself or thereafter. This was a tragedy of place.

The ritual enacted today paid tribute both to individual loss and community despair. People gathered at 15 spots along the Avon River that winds through Christchurch and dropped flowers into the water. The river leads to Pegasus Bay and the South Pacific Ocean.

A Flower from before the Pharoahs


A plant newly grown from an ancient fruit placenta may provide a key to evolution.

Taking a giant leap back in time, Russian plant scientists claim to have succeeded in growing a plant from tissue 32,000 years old.

The New York Times reports on the research of Svetlana Yashina and David Gilichinsky (to be published tomorrow in The Proceedings of the U.S. National Academy of Sciences).

The scientists and their team found fruit of a narrow-leafed campion plant, buried by an ancient squirrel inside the bank of the Kolyma River in Siberia.

“Working with a burrow from the site called Duvanny Yar, the Russian researchers tried to germinate the campion seeds, but failed to do so. They then took cells from the placenta, the organ in the fruit that produces the seeds. They thawed out the cells and grew them in culture dishes into whole plants.

“Many plants can be propagated from a single adult cell, and this cloning procedure worked with three of the placentas, the Russian researchers report. They grew 36 ancient plants, which appeared identical to the present day narrow-leafed campion until they flowered, when they produced narrower and more splayed-out petals.”

Sadly, Dr. Gilichinsky died of a heart attack Saturday.

But if DNA studies and radiocarbon dating confirm the discovery, the plants that he and his team have grown would be by far the oldest plants grown from ancient seed. The previous record holder was a date palm.

Weaving among Hardiness Zones


Kentuckian Allen Bush pushes the limit with new plants from Florida, seduced by the USDA’s new maps.

The long awaited interactive garden tool was released a few weeks before our Florida vacation. I didn’t study the new map, though I could see Louisville, Kentucky, was colored some shade of green. There were adjacent greens but I’m red-green colorblind. It was all a muddle. 

On our vacation to Sanibel Island, a few weeks later, Mary Vaananen, my Jelitto colleague, emailed and announced that Louisville had been upgraded from 6b (-5 F to 0 F/-20.6 C to -17.8 C) to 7a (0 F to 5 F/-17.8C to -15 C). I started shopping for native Florida plants the next day.  Florida and Kentucky have a lot in common. Florida once sat at the bottom of an ocean floor; so did Kentucky.  In 1824, botanist Constantine Rafinesque wrote in Annals of Kentucky: “The briny oceans cover the whole land of Kentucky.”  Kentucky was only 10 degrees north of the equator, when we were sitting under a shallow ocean in the Devonian Period 380 million years ago.
