Ipomoea stans

I'm on vacation, so please accept my apologies for the brief entries. -- Daniel.

And another thank you to David Tarrant for these two photographs, also taken in late July near San Miguel de Allende, Mexico in late July. Much appreciated!

Commonly known as tumbavaqueros in Mexico, Ipomoea stans is a Mexican endemic (so has a more restricted range than yesterday's Ipomoea longifolia). It is estimated that there are somewhere between 500 and 700 species of Ipomoea, making it the largest genus in the Convolvulaceae.

I should have noted it in yesterday's entry (as it was Thanksgiving in Canada) -- the "sweet potato" that often finds its way onto Thanksgiving tables is also an Ipomoea: Ipomoea batatas.

I have to tell you Daniel. I enjoy the brief articles just as much as the more detailed articles, but the pics are what makes it all worthwhile. Thanks for all the pics and descriptions, regardless of how short or how long.

I needed this beautiful flower today. Home sick with a cold and it's cloudy. Thanks for the little bit of sunshine.

Thanks for taking time out of your vacation, Daniel! Love the pictures -- They always make my day.

Mercy commented:

So does tumbavaquero translate as cowboy's grave? Looking on the Mexican site this plant has a lot of evocative common names!

Diego Gonzalez commented:

Hermosas fotos.

I love the morning glories. The flowers are splendid, with their five-pointed star pattern, especially the blue and purple ones. I love the spiral flower buds, and watcing them untwist through the stages of opening. Even the way the flower edges curl inward as they fade and wilt. I love the way the stems twine around supports and fences, and around themselves, as they climb.

I had a few blue morning glory plants planted along a fence some time ago, and once made the mistake of fertilizing that patch of the flower bed, thinking I was being good to the plants. At first I was very happy to see thick lush plants developing, with lots and lots of great big leaves... and then hardly any flowers at all. Very disappointing -- I really missed the flowers that year. I concluded that this must be one of those plants that needs a little stress in its life, before it will flower.

Tumbavaqueros:

the name comes from: vaquero= cowboy and tumbar: bring down.

Translated: this plant when dried becomes a ball that brings down the cowboys of the horses
