Quercus suber

Quercus suber. Oak cork. Pen and ink on 3.5"x2.5" Bristol board




If you prefer wine and champagne bottles sealed with cork, then you will like or appreciate  this oak, Quercus suber or Cork Oak. This tree is native to the countries of Portugal, Spain, Morocco, Algeria, Italy, Tunisia and France. Quercus suber is known for the renewable resource it provides, cork. The cork is derived from the thick outer layer of the bark which is harvested from the tree first at 25 years of age and then every nine to twelve years thereafter. Here is a very informative article on Quercus suber from Ecology.info. In it, you will find an excellent photograph of Quercus suber showing the harvested sites of the tree. Here is another excellent tree specimen image. Cork has been used since ancient times for many reasons, among them, for sealing jars, making beehives and roofing. The use of cork to seal wine bottles was introduced by the Benidictine monk, Dom Perignon (1636-1715). He was cellar master at the Benidictine abbey in Hautvillers.

The leaves of the Quercus suber are evergreen and oval with a pointed apex, rounded base,wavy margins with very shallow spiny lobes, adaxially glabrous, blue green, densely pubescent abaxially. It has a hairy petiole between 0.8-1.5 centimeters long.

The acorn is 1.5-3 centimeters long, ovoid, enclosed almost 1/2 by cup, conical, with long spreading scales, maturing in 1 year.




A note about the direction of my blog:

I have been posting a lot of acorns and leaves lately. This is  a personal project mine.  There are  over 600 oak species and varieties. I am attempting to draw as many acorns and oak leaves, as I can. Please don't ask me why I am drawing these, I am not able to give you a concrete reason, except that I am still enjoying it, but mostly, it is because they are small (ATC-sized) and portable that they fit my busy work schedule. I draw most of these acorns and leaves when I need a mental break from my hectic schedule and stressful and mentally taxing job. The posts are scheduled, so please do not feel obligated to leave a comment. I am leaving the comment section open to save those who wish to leave me inquiries related to my posts and drawing, from writing emails. Many of you have sent me emails, letters and gifts. Thank you for your generosity. I appreciate your kind gestures, words and gifts. Thank you.

Sincerely,
Ces

Just keep on drawing them Ces. We used to have one of these in our garden before the fire. It was quite a rare specimen and I treasured it.
For quite a while there was nowhere to leave comments on your blog, i am glad you have re-activated them.

Tsup, tsup . . . Arija

Ces, you do not need to explain or justify your desire to draw acorns! Art is by nature obsessive, I think. Certain subjects/shapes/symbols/colors just call to us at certain times, & following the call is what makes us who we are.

I have a bowl made of natural cork bark that my folks brought back from Portugal some years ago, & it has the most beautiful undulating contours & subtle gray colors... it is the closest I've come to seeing a cork oak, if you don't count all the bulletin boards & wine corks!

p.s. I am delighted to see that glossary of terms to the right! As you know, that sort of thing is one of *my* obsessions!

Wow...I never knew that cork came from an oak tree!

I agree with Leah above...no need to justify your fabulous acorn drawings. I'm a HUGE fan of them! And she's so right...we draw what we're compelled to draw. I recently started a series of small drawings and I love doing these kind of "bite-sized" pieces. If something goes awry on one, it's no huge loss of time, and I think that gives me a sense of freedom. I'm a word person as well...love the glossary, love the acorn banner. Keep the acorns coming!

Bella Sinclair said...

Excuse me. But why are you drawing so many acorns and leaves???

My African Grey parrot 'Gumbo' asked me to thank you for your informative post on the cork oak which he read with great interest. He cannot type, but he does enjoy going through his collection of old wine corks and selecting one to dismantle with his beak. I think he prefers the squeeking sound corks make when chewed on. I have to keep a large supply on hand for him and friends know to donate their old corks to this cause. So thank you Ces, Gumbo and I learned something today.

Do big oaks from little bitty corks grow?

Why are there so many differing oaks, and oak leafs?

Who made God?

I sure feel stupid tonight...or every night?

PEACE!

Ces said...

Aaw, Arija, that is so sad. That fire took everything! It takes so long for the tree to be harvested - 25 years!!! That's almost like raising a child and seeing them on their own.

Ces said...

Leah, you explained that so well. Obsession it is for sure. Sometimes a curse, can't shake it off. I love cork. I have a Portuguese friend who lived in the region of the cork oak trees when he was a child. He goes back to visit and always tells me about the grove of Quercus suber lining the streets to his parent's home. What a sight is that, I imagine.

Ces said...

Thank you Sarah, wow, coming from you, I am very honored!

Ces said...

Because I know they will make you happy.

Ces said...

Hahaha! You are welcome Gumbo and Ted. You heard about that parrot joke, right?

Ces said...

Sigh*** Maybe you just need sleep.
