All things green

Have you ever seen a flower with two colors on one blossom? Yes, of course you have.

Have you ever seen a flower with two colors on one blossom where the colors are divided exactly down the middle? Now that’s a little more rare.

How this occurs is an interesting process.

Let’s briefly review how a flower is formed.  Think back to your high school biology. Plants are made up of small, microscopic structures called cells.  The cells grow and divide over and over again until you have a fully formed plant.

Inside of the growing tip of a bud (called a meristem) there are many many cells dividing like crazy in order to get a flower to form and blossom in one growing season. Each time they divide, they pass on a blueprint of how the flower is to be built. This is called genetics.

All of those millions of cells start out as just one cell. That one cell divides into two cells.  At this very early stage, something happened to one of those two cells.  The genetic blueprint didn’t get copied exactly right, the blueprint says it is supposed to be a Mum blossom but instead of painting it yellow, it specifies pink as the color.

All of the descendants  from that one pink cell “thinks” the flower should be pink, while all the descendants from the yellow cell know it is supposed to be yellow because it is a yellow Mum.

Those darn pink cells are stubborn and continue with their pink idea until the flower is completely built.  And guess what? Exactly half of the flower is pink and the other half is the color it is supposed to be…yellow.

In the horticulture trade this is called a chimera.  This is one way how different varieties are begun.

An observant grower will notice something unusual happening with a single plant, often just a single stem on a plant. If it looks promising, he will reproduce it and hopefully turn it into a new variety.  If he has a crew of farm hands helping and he doesn’t go to check his crop, this small detail will more than likely go unnoticed and the opportunity to create something new will be lost.

Chimeras don’t always reproduce themselves very well. They are unstable, which is how they became chimeras in the first place.

A couple examples of chimeras include thornless raspberries and different colors of Poinsettias.

So, will I make a million dollars producing pink and yellow Mums?….probably not.

A couple of weeks ago I had an early morning visitor to the garden. Actually I believe he stayed over night until I found him in the morning.

He reminded me that gardening can have many pleasent surprises.  Sometimes, things come  your way unexpectedly.

It was still pretty chilly out, the sun wasn’t very high in the sky, so he was still resting on one of the potted Mums we are growing.

I knew he would be leaving as soon as he could so, I hurried in to the garden shed to grab my camera.

The visitor was a dragonfly covered with so many droplets of dew that he looked like he was encrusted with jewels.

I know I’m not the only person to be delighted by this sight. The American Society of Jewelry Historians has a brooch in their collection made of gold, platinum, demantoid, ruby and diamond. It was made by Emmanuel Gattle & Company way back in 1900. I’m sure the designer was inspired by a dragonfly he saw.

I imagine him being given an assignment by his boss to come up with an idea for a new piece of jewelry. He was probably unable to sleep all night and got up before breakfast to take a walk in the garden. He looked over and saw… well, we know the result of what he saw.

Recent international politics have been influenced by dew covered dragonflies and other insects.

Former US Secretary of State and Ambassador to the United Nations, Madeleine Albright owns at least seven dragonfly brooches  that she has worn  during diplomatic visits to  foreign countries.

Here she is wearing a brooch in the shape of a bee during talks with Yasser Arafat…who knows where she wore the Dragonfly!

These unexpected sights in the garden can really get you thinking of things. I better stop this “stream of consciousness” right here.

Madeleine Albright’s book Read My Pins became available in book stores just last week.

Now that we are at the end of the summer gardening season, at lot of us will begin pulling out  old and worn out plants and tossing them in the compost pile.

I found this root attached to a sweet potato plant:

Notice the knobby, bumpy nodules.  This is not normal for a sweet potato root. The abnormal growth is caused by a nearly microscopic worm-like creature called a nematode.

Nematodes are the bane  of sweet potato farmers in the southern states where sweet potatoes or other vegetables are grown year after year in the same spot.  In addition to gnarled roots, nematodes also cause reduced yields.  Often the damage shows up as black spots under the skin of the tuber that are not seen until the root is peeled leaving an unusable potato.

This nematode damage can occur on almost any common vegetable plant.  If you find a root that resembles the one in the photo, destroy it and don’t attempt to compost it, otherwise you risk spreading the pests to other parts of your garden.

There is no method of control for nematodes in the garden except rotating your crops.  You must rotate to a grass-related crop such as sweet corn in order to break the life cycle of the nematodes. “Regular” garden crops will support nematodes in the soil.

Knobby roots on legume plants such as peas and beans are  normal and not caused by nematodes, so don’t dispose of  them.  Beans and peas have nodules on their roots that harbor beneficial bacteria. In this case the bacteria  are beneficial to the plant and actually produce fertilizer in the form of nitrogen that the beans use to grow.

Chances are you won’t see these symptoms in a new garden because the nematodes have not had enough time to multiply.

Happy Composting,

Here’s a nice flower combination that was quite successful for us this year.

The purple flowers are  Gomphrena ‘Purple’.  The orange flowers are Zinnia ‘Profusion Orange’.

Both Orange Profusion and Purple Gomphrena are about 14″-16″ in height. I used them here all by themselves in a sloping bed which really showed them off.

The two colors go well together and the blossom shapes compliment one another as well.  Also, the blooms  held up nicely  all season. You can see  that they are still going strong.

Make a note of it in your garden notebook to look for these varieties next spring.

I came across this horn worm on our grapes this morning. There were over 2 dozen white objects attached to its body.

It had been parasitized by another insect, most likely some species of wasp.

These types of wasps reproduce by depositing their eggs with their stinger into a host insect.  In this case the unsuspecting insect is a horn worm.

The eggs soon hatch inside the caterpillar’s body. The newly released wasp larvae then begin to feed on the “innards” of the host insect while it’s still alive.

When the young wasp larvae have grown to sufficient size, they form”cocoons”, those white structures you see on the back of the caterpillar. The wasp larvae undergo a transformation inside the cocoons and emerge as fully developed wasps.

You can see by the size of the cocoons that these wasps are tiny compared to the paper wasps or hornets we normally see buzzing around the picnic table.

Let the balance of nature help you in your garden. When you see a caterpillar that looks like this, don’t squash or spray it, let the new wasps be “born”.  They will soon be flying around looking for more caterpillars in your garden to parasitize.

By the way, this type of wasp does not sting or disturb people.

If you didn’t make it out to fair yesterday (Wednesday), you’re too late!

The Monroe Evening News hosted a “Meet the Bloggers” evening in their County Fair booth.  It was a good chance for readers and bloggers to talk to each other face to face.

So, if you missed us, plan on catching us next year.

In the meantime, there’s still plenty of time left to enjoy the fair.  Stop in and see the folks at the News anyway. Their booth is just a couple of spaces away from the historic flowing water faucet in the MBT Expo Center.

Bob

I hope many of you are enjoying the Monroe County Fair. If not, you better get out there soon because fair week is about half over. My how time flies!

Which reminds me, Judy and I will be at the Monroe Evening News booth on Wednesday from 6:00pm to 9:00pm or so. We will be joining other bloggers from “blogsmonroe” for an evening of meeting with you, our readers, in person.

Judy and I hope to see you there.

Thar’s gold in them thar hills!!

Not the precious metal type of gold, but the horticultural kind you can find in Helenium ‘Dakota Gold’.

Helenium is the genus name for a grouping of plants that includes Sneezeweed. Many of these species and varieties are tall, often growing over four feet in height and having large orangish flowers.

Dakota Gold grows only about a foot tall and about a foot and a half  in width.  It’s growth habit makes it ideal for planting in the front of a bed.

It also produces an abundance of dainty, bright golden yellow flowers.

I used it in a spot where I wanted a swath of yellow but didn’t want to use something over-powering like Marigolds. A single plant of Dakota Gold, or a planting of just a few, would not be very impressive,  but plant a good sized drift of them and they suddenly become something special.

As far as I know, last year was the first year Dakota Gold seed was widely available. We should be seeing more and more Helenium Dakota Gold being made available in garden centers in the future as more gardeners discover this wonderful little plant.

…and that’s nothing to sneeze at!

One of my favorite potted plants is our Olive Tree.  We have two of these trees in pots and they seem to be quite happy living in their containers.

They don’t have big showy flowers or give off a sweet scent. What I like is their graceful form.

The branches grow in sweeping curves that support delicate silvery-green leaves that compliment surrounding plants. Olive leaves also make a refreshing tea which I drink from time to time.

Our Olive Trees are about five years old and are nearly three feet tall in the pots and do produce actual olives.

They have to be over wintered indoors because they are not hardy enough to withstand our winters. You can just bring them into a dimly lit, cool storage area (45F-55F) when the autumn temperatures start to fall  and reduce watering to a minimum. Or, keep them going all winter in your greenhouse, they’re not all that picky.

Ah-luv those Olives!

This time of the year it is always a treat to see the Eremurus blooming. Because we have them planted in an area under the walnut trees where not much else is growing, they seem to shoot up  out of nowhere.

Foxtail Lilies in bloom

As you may or may not know, it is nearly impossible to grow most plants under Black Walnut trees, but the Eremurus seems to live there just fine.

These plants are native to Tibet where the summers are hot and dry but have good fall and spring rainfall. This often describes the weather in this part of the country as well.  It’s no wonder that Foxtail Lilies do well here.

Our Eremurus are the yellow variety (bungei) and range from 3 to 4 feet tall.

From a distance, the hundreds of tiny flowers on the stalk merge together to give them their unique look.

Eremurus Flowers

It’s when you get closer that the individual flowers become apparent.

Foxtail Lilies are grown from tuberous roots that in themselves have a unique shape, they sort of remind me of star fish.

Fall is the time when the roots are planted, so you have some time to track some down and get them ordered.  We got ours from K. van Bourgondien and Sons  (dutchbulbs.com).

There is one thing I would recommend when planting your Foxtail Lily this fall, and that is to mulch them well. They are a little weak getting started the first fall.  However, after that, they thrive here in southern Michigan.

So, put Eremurus  on your fall ” must-buy list”.
