The Great Red Spot is a great anti-cyclonic (high pressure) storm akin to a hurricane on Earth, but it is enormous (three Earths would fit within its boundaries) and it has persisted for at least the 400 years that humans have observed it through telescopes.

An upstart storm now (since 2006) rivals the gas giant Big Red Spot as king of storms. A third red spot has appeared alongside the Great Red Spot and Red Spot Jr. in the turbulent Jovian atmosphere.

Vertical Gardening is a modified way of growing plants while being a wonderful solution to create an attractive and functional garden from limited space.

Leaves into spines…

Cacti are distinctive and unusual plants,
which are adapted to extremely arid
and hot environments,
showing a wide range of anatomical and
physiological features which conserve water.
Their stems have expanded into green
succulent structures containing the chlorophyll
necessary for life and growth,
while the leaves have become the spines
for which cacti are so well known.

All cacti are native to the America’s and surrounding islands, with one exception: Rhipsalis baccifera.

“Green” ROCKS!

January 5, 2009 · 8 Comments

Living Stones…were originally discovered by William John Burchell (English explorer – naturalist) in 1811 when he picked up a curiously shaped pebble and it turned out to be a plant!

Lithops
is a genus of succulent plants native to Africa, their bodies are in
fact a pair of leaves that have evolved to efficiently retain whatever
moisture becomes available to the plant. To minimize any evaporation
the leaves have become so truncated that they have lost the appearance
of a normal leaf and have become rounded like a pebble! This has made
them less obvious to foraging animals since they mimic the color and
appearance of the soil and stones in their surroundings thus standing a
great chance of survival.

The "Split Rock" plant looks like a green speckled rock split open in half.

"Lithos" means "stone" and "opsis" is "face" in Ancient Greek;
therefore, "Lithops" means "stone-face".

The pebble in the brook secretly thinks itself a precious stone.

A windowsill moon!

December 22, 2008 · 13 Comments

Moon Cacti are not a genus. it’s the result of a cactus graft, an
actual physical union of the vascular systems of the two plants.
Their
colored top is not normal—this color occurs because the cactus does not
produce chlorophyll. Thus this living arrangement is absolutely
necessary because the top cannot survive without chlorophyll and the
bottom supplies it.

Wishing You All a very, very “Merry Christmas”,
specially the “Happy Cactus Monday” group…

“Ruby Moon” (original in process – not finished) • watercolor, wax on ricepaper

Red is not the only “achlorophyllous” color that occurs; in fact there are
many beautiful genera which are yellow, pink, orange, or even multicolored.
This Moon Cacti is a great windowsill culture but please keep out of direct sunlight
because the sun would fade out the color and also it is easily sunburned!

There’s part of the sun in an apple; There’s part of the moon in a rose;
There’s part of the flaming Pleiades
In every leaf that grows.
