First Man-Made Leaf! The Future has Changed.

Silk  Leaf by Julian Melchiorri  

The future has arrived.  And it arose from Julian Melchiorri's Silk Leaf project, which came out of a Royal College of Art's Innovation Design Engineering course.
He collaborated with Tufts University silk lab to suspend  chloroplasts in a matrix made out of silk protein. And we are 'off to the races'!
Julian Melchiorri Silk Leaf Project 

What has transpired (my bad hort. pun) is astonishing...

Like real leaves, the Silk Leaf can  produce oxygen if it is given light and a small amount of water.

 The possibilities are tremendous! Below is a Leaf Light that gives off oxygen  :

This is what he looks like - young!:

The future has now changed!  Here are what buildings will look like to our grandchildren:

And go here to see a the video of Julian explaining it all:

Angelface Blue and Dark Violet Angelonia - a Flower that Keeps Giving

Image
(Angelonia with Helichrysum, petunia, Johnsen Landscapes) Blue is everyone's "favorite color."  It is, hands down, the most popular color worldwide and is the least "gender specific" color, having equal appeal to both men and women. Now Purple is giving blue a run for its money as the second favorite color.... Blue is the favored color for toothbrushes, so that says it all!  ( this info is from a great website: Sensation Color ) but can purple be far behind? Scientists have found that the color blue causes the body to produce chemicals that are calming. This may be why we all like to be around blue....stare at this square and see if it calms you. In fact, over the past decade, scientists have reported the successful use of blue light in the treatment of psychological problems such as addictions, eating disorders, impotence, and depression. Moreover, a deep blue/purple such as Indigo or Deep Violet symbolizes mystical wisdom and spiritual insight. It incr

No-Fail Tips for Turning Hydrangeas Blue!

Image
(photographer - unknown) Everyone wants Blue Hydrangeas.  The rarity of naturally blue flowers is an irresistible draw to gardeners.  How to Turn Your Hydrangeas Blue?  Here are a few tips from Proven Winners: Nikko Blue Hydrangea from Missouri Botanical garden 1. Be sure you’re working with the right kind of hydrangea.  You must have a Hydrangea macrophylla or H. serrata to have pink or blue flowers.  (photographer -unknown) 2. Aluminum availability determines flower color. The availability of aluminum makes the flowers turn blue. Without aluminum the blooms will be pink.  Soil pH must be low or acid (5.2-5.5) for the plant to absorb the aluminum. from nely.bluehortensia blogspot.com 3. Color changes need time to take effect.  Consistent treatment is necessary to  turn your hydrangeas blue:  Plant your hydrangeas in a phosphorous-free medium, and use a phosphorus-free fertilizer with lots of potassium (i.e. 25-5-30).

Repurposed and Recycled - Creative Ideas for Garden Design

Image
Nothing like piano keys to liven up a garden space....(above photo from Stone Art Blog) Recycling can be many things to many people... or, in other words,   " One man's trash is another's man treasure" from Stone Art Blog This piano was placed here in the garden. Here is what Sunny Wieler of Stone Art Blog wrote about this: "Besides being a passionate gardener, my dad is also a passionate piano player, so a few years back we got him a new piano for his birthday. So the old piano spent a while in the shed before he had the great idea to put it out in the garden..." Little did Sunny's dad know that he was at the forefront of the conceptual art movement:...they would say something like this is a testament to the natural decomposing processes, a statement of the fragility of life, the impermanence of existence... his dad would say, 'Hey, why not put it in the garden?" photos of broken concrete from Bourget Bros web

The Magnificent Purslane - Edible Landscaping at its best!

Image
What was one of Mahatma Gandhi's favorite foods?  and what did Henry Thoreau eat while residing at Walden Pond?  PURSLANE . Purslane, long considered an obnoxious weed in the U.S., is, in fact, full of vitamins, minerals and fatty acids!  And now this overlooked gem - considered 'one of the most nutritious greens in the world' -  is receiving the attention it is due. Usha Palaniswamy of the Department of Plant Science, University of Connecticut, reports that, "Purslane is receiving much attention for cultivation by the United States Department of Agriculture as part of their effort to bring about a modification in the western diet with increased intake of fresh fruits and vegetables." Purslane contains a high concentration of alpha-linolenic acid (ALA), one of the highly sought-after Omega-3 fatty acids. It has several times the concentration of ALA than is found in spinach.  So throw away those fish oil capsules and grow your own Omega-3 fatty acids! It

My one day Class Wednesday April 16 in NY - Jan Johnsen

Image
I am teaching a one day class on Wednesday April 16 at the NY Botanical Garden  It is a fun, eye opening and fun class!            (class size is limited.) I  share my insights into landscape design and how to use various cultural and ancient traditions in a garden. I discuss how to use the compelling duality of Yin and Yang in a setting, explain how each of the four cardinal directions (north, south, east, west) affects us differently, which proportions create a more harmonious setting.  I also show how to place rocks in the landscape according to the Japanese understanding. Everyone loves this. and of course, I discuss Color and its effects on our wellbeing... I show 2 beautiful powerpoint to illustrate my talk..  Handouts reinforce the information I provide. Here is what students have written: No wonder you were instructor of the year! Your talk was delightful, Jan. You gave us all a thoughtful, colorful start to planting season. I have some great
