How Bees See

20190828_111547

Bees can’t see red. They don’t have that color receptor.  Human color receptors are based on red, blue and green. Bee’s receptors are based differently – on ultraviolet light. That is blue and green. So, red flowers appear black to bees. How interesting to learn about the eyes of bees, especially since I’ve been told my other flying favorite, the hummingbird, favors red flowers.

I’ve always loved blue flowers.  I didn’t know the bees did too. A dive into Bee Culture: The Magazine of American Beekeeping explains all about how bees see. Petals are a different color than leaves for the purpose of attracting pollinators and, surprise to me, many patterns in nature are invisible to us. Even though many gardeners love blue flowers, the truth is blue recedes in our vision. Yellows and reds pop out to us.

To help our most important pollinators it’s worth incorporating blues from spring to fall. Again an article in Bee Culture leads us through the season with appropriate blues.

In spring plant Siberian squill, Pulmonaria, Grape hyacinth and Forget-me-not.

In summer make sure you have hydrangea, cornflower, bachelor button, meadow sage, cat mint, Russian sage, veronica and speedwell.

 

 

 

Of course there are many more bee-friendly flowers to consider. Blues delight our eyes and feed the bees. In turn the bees make it possible for us to eat almonds, apples, blueberries, cherries, avocados, cucumbers, onions, grapefruit, oranges and pumpkins just to name a few. We get the best of that trade off.

The Lower Shore Land Trust

Our speaker at our July garden club meeting was Kate Paton, Executive Director of the Lower Shore Land Trust.

The mission of the trust is to preserve rural lands, promote vibrant towns and build a healthier, more connected Eastern Shore. Kate spoke on the environmental benefits of pollinator gardens.   To those ends the trust wants gardeners to work towards a healthy environment for the pollinators in our midst.

They sponsor a Pollinator Certification Program. The criteria for certification are four fold. You must have food sources. That could be native plants, host plants, fruit trees, a feeder and diversity of scent, color and size. Water sources must be present. That could include a pond, river or stream, a birdbath, a hanging drip bottle or a butterfly puddle area. The pollinators also need cover. It may be natural shelter or a constructed shelter, canopy layers and nesting or basking sites. Lastly, certification requires conservation practices – composting, a rain garden , xeriscape, native plants and a reduced lawn area and no fertilizer use. All of these criteria are familiar to gardeners and good suggestions for good stewardship of the land.

beeKate enumerated some reasons why we must take seriously the impact our practices have on the land. Hedgerows are no longer common dividers of our farm fields. The pollinators have a need for that diversity in the landscape. As gardeners, we can help make up for the loss. The Trust has a demonstration garden at their headquarters in Snow Hill. It’s worth a visit.

Since I’ve added native plants to my yard, I’ve seen many more bees, butterflies and birds. By signing up for a pollinator friendly garden, your yard will post a sign that may encourage your neighbors to join in the mission to promote the natural heritage of the Lower Shore.

My Mutant Spruce

dwarf spruce1

 

The lovely dwarf Alberta spruce (Picea glauca ‘Conica’) in my front yard is about 15 years old. It’s neatly shaped with delicate, slow-growing branches. It’s less than five feet tall – just about the size that fits my front yard. It seemed happy growing in its plodding way.

That is until today. Today is when I noticed the strong arm of a large white spruce reaching out from inside the tree.  A giant spruce arm was hiding there. It looked as though it was trying to climb out of its dwarf jailor.

I quickly went to the Internet. “What’s this,” I queried.

Quite common was the answer. The dwarf Alberta spruce is itself a mutation of the white spruce (P. glauca) which has a mature height of 60 feet.  The dwarf mutation was first sighted in Alberta, Canada in 1904 by two botanists waiting for a train at the railway station.  Many foundation plantings later a bud on my tree has reverted back to the original spruce. It’s called a genetic reversion. Expert advice is “nip it in the bud.” Is that where that phrase came from?

Shades of Charles Darwin. What happened to my spruce started me thinking about the capabilities hidden inside all living things – a window on natural selection. I’ll never know if it was stress that made that prickly arm reach out, nor how the phragmites manage to colonize empty spots around my house, nor why the gazania feels the need to fold up its petals at nightfall. It’s mind boggling to think of the wonders in our world.

The Vinegar Hit Man

Every year the shore birds do me a favor. They drop poison ivy seeds everywhere in my garden. I’m allergic and I know each time I make contact I’m in for ten days of itching. Just two weeks ago I put on disposable gloves and long sleeves and ripped out a bunch of it. I thought I had taken enough precautions. I use Tecnu  and it’s good at removing the oil. Unfortunately, you have to know where that oil landed. I think it spritzes through the air. I didn’t realize it hit my face. A day later I was swollen and itchy and looking like I’d lost a battle to a vicious foe. I vowed to keep clear of the stuff forevermore. The trouble was, I still needed to get rid of the vile ivy. I thought I’d try a concoction I’d been reading about on the Internet. Here’s the recipe:

1 Gallon white vinegar

2 cups Epsom Salt

¼ cup Dawn liquid detergent

poison ivy 2poison ivy 1

10 AM and 3 PM

Here’s what happened. On this sunny morning the triple-leaved culprit looked lushly green. I doused it with the special mixture. Five hours later the lushness was gone, replaced by dried, crinkled leaves. Now, I didn’t know what was going on under the dirt, but I hoped the roots suffered the same fate as the leaves. Time will tell.

Of course, this mixture must be used with caution.  Any plant you happen to spill it on will sport crispy leaves. So it’s not a solution if the ivy is entwined among the lavender or threading through the daylilies.

The local extension agent suggested I get 20% vinegar. My gallon from the grocery store was only 5%. Just another thing I didn’t know – there is cleaning strength vinegar. If 5% crisped up those leaves in five hours, 20% would surely whack them. Take note – 20% will blister skin and do worse to eyes.

Further research turns up quite a bit of controversy. Some say the vinegar only gets the leaves. Sounds like repeat applications are necessary. The good thing is the vinegar quickly breaks down in the soil, so no problem with planting at the site a week later. And Epsom salts are made of Sulphur and magnesium. Both good for the soil.

In theory gardening conjures visions of relaxation amidst the beauty of nature. Not so for us on the ground. There is battle to be waged with formidable foes – the weeds, the poison ivy, the deer. We must be ever vigilant or that vision will not be our reality.

Happy Father’s Day

stool

 

Happy Father’s Day, Dad.  Wish you could see my garden where a number of your pieces reside. I have a stool you made from a big, fat tree stump.  You fitted it with three legs and varnished it up good.  It’s a slice from a swamp maple that once grew on a Mississippi River bank. When its leafy days were over you thought that wood’s too pretty to throw in the fire pit. You didn’t trim the skirt of bark. Maybe you thought the dignity of the woodland resided in that rough protective coating. Maybe you thought it just looked better that way.

You took the trouble to drive it across the country to my house and now it sits on our front porch next to a Majesty Palm (Ravenea rivularis). The stool came out of the Mississippi bottomlands and the Palm is native to Madagascar. Two plants from opposite sides of the world sit comfortably together. Nearby the Atlantic tides cycle through the day.

You recycled before we had recycling bins. There is something spiritual about making a new use out of something that is about to be discarded. Its life isn’t quite over. You put on your practical thinking cap and gave it a second chance.  From many examples, you gave your children the seeds to look at the true value of things, take no things for granted and chose re-making as part of living a satisfying life. I know,” live within your means” was a favorite mantra out of your mouth and into our ears.

These words reside in the realm of cyberspace. A place we never knew existed when you were here. Maybe in that unseen orbit you’ll run into them. It would make me happy to think that could happen.

HAPPY FATHER’S DAY, DAD.

Little Charmer Cosmos

cosmos7 - CopyThe Spanish priests named this little Mexican charmer cosmos, indicating it is a balanced universe on its own and therefore a thing of beauty. I grew Sensation mix (Cosmos bipinnatus) from seed indoors in early spring. Definitely a plant for dummies – they sprout quickly, transplant with ease and love lousy soil and dry conditions in bright sun. They flower until frost with some deadheading and reseed the next year – fingers crossed.

They are shallow rooted so do well among lilies. They are a perfect cottage garden and cutting garden choice. cosmos11 - CopyA brown bottle on our coffee table will hold three or four blooms every day until frost. The colors range from downy bright white to almost chocolate velvet.

It’s best not to give cosmos a lot of fertilizer or rich soil. That signals them to put out a mass of foliage and not much in the way of blooms. I did transplant some to an area covered with Leafgro and they have yet to flower.  Note to self: read up and heed the experts.

Cosmos, also called Mexican Aster, is part of the Asteraceae family so is a close cousin to sunflowers, daisies and asters. cosmos6 - CopyThe foliage is fernlike, giving the plant a delicate look and a beautiful contrast to the stout, sturdy leaves of lilies. Mixing Cosmos among the strap-like leaves of Stella de Oro daylilies would also be a pleasant combination.

Cosmos comes in handy as an introduction to flowers for young gardeners. Quick sprouting and easy blooms reaps generous rewards and will surely charm budding horticulturalists as they did the Spanish priests so long ago.

Bird Lessons from the Soulful Gardener

Did you know that domestic cats kill more birds than insecticides? That’s the story from the American Bird Conservancy.

It’s news to me. I thought letting the cat out was a rather harmless activity. I found out the Bird Conservancy has a “Cat Indoor Campaign” in which owners sign on to keep the cat indoors. Of course it’s only half the problem because there are many unowned cats roaming the countryside and feral cat communities that contribute to the slaughter of about 2.4 billion birds every year in the United States alone.

I was lucky to be a guest at the May meeting of the Master Gardeners of the Eastern Shore. The speaker was Heather Zindash, a Certified Professional Horticulturalist. She spoke to us about the need to keep the birds in mind when planning a garden. Her website, The Soulful Gardener is a “gardening and therapy-through-horticulture stopping place to help connect people with gardening and nature.”

 

Heather was a font of bird and garden information. I’d never heard of “nature deficit disorder.” Now I know there’s a name to the epidemic of time spent staring at a screen be it cell phone, tablet, computer or television. Connecting our children to the outdoors sounds like a preeminent goal for parents.

She talked about birds being “biological indicators”. Remember the proverbial canary in the coal mine.  Birds need much more oxygen than humans because of all the flying they do.  Therefore they are bioindicators, detecting toxic gases before we do. The state of their health is a good forewarning of environmental decline because they carry measurable toxins in their feathers.

As gardeners we should consider the three elements needed to attract birds to our gardens: food, water and shelter. All we need to think about are berries, nuts, seeds and nectar for our feathered friends and water in the form of bird baths, ponds, creek or rain gardens. Adequate shelter would be our shrubs, evergreens and thickets. Pay attention to these three elements and the birds will reward you as a natural insecticide. The circle of life will be complete.

Heather talked about the Christmas Bird Count, the longest running citizen science project, sponsored by the National Audubon Society. It’s been going on for over a century.  Every year the count runs from December 14 through January 5. To participate check the Audubon page for a circle of counters near you. This is not a count that you do on your own, you must officially join a circle.

Possibly many of the master gardeners already have much of this bird information in their heads, but Heather loaded me up with new knowledge of the importance of birds in our gardens.
