But the columbine’s true Latin name is Aquilegia which translates to mean eagle. It was so named because the spurs of this flower reminded some observers of the the talons of an eagle. How neat is that? That’s pretty neat!

Living with Black Walnut Trees

When dealing with mature trees many times we just think about the shade factor and if the tree has dense or dappled areas under it. Also root competition comes to mind as well as dry ground from rain being caught in the canopy before it can get to the soil. But some trees emit substances that can negatively affect near by plants and Black Walnut is one of the most notorious for harming it’s neighbors.

As a popular choice for shade canopy, Black Walnut is also grown for its lumber production and dye properties in its ‘fruits’. The concern lies in the production of Juglone which is in the roots, leaves, nut husks and even carried by water dripping of its leaves during rain. Areas effected by a tree go well beyond the canopy through the root structure and may effect nearby roots as far as ½” away.

The only real solution to black walnut toxicity is to install tolerant plants. Fortunately there a few plants that show little or no effect in relation to Juglone toxins. Many symptoms are a mimic of diseases or physiological disorders so look up before diagnosing a plant. Even cutting the tree won’t solve the problem since the roots still contain the chemical.

Plants to steer clear of are: Nightshade (tomatoes, peppers etc), yews, Pines, Azalea, Potentilla, Hydrangeas and lilacs. Some resistant to Juglone include: Cherry, Crabapple, maples, dogwoods, carrots, onions, snap beans, arbor vitae and daylilies. Checkout the Morton Arboretum  for a comprehensive list of plants.

Planting Harsh Sites- SALT TOLERANT

When designing street scapes, Boulevard plantings or landscapes that border driveways and sidewalks a consideration factor is snow/ice and the control method that will be used. Many of these areas will receive a dose of de-icing salts in the northern climates. Salt damage can show up through aerial spray or build up in the soil over time through direct contact or runoff.

Other then careful plant selection there are a few ways to control salt effects in the landscape including little to no use of de-icing salts, spread salt after shoveling, is salt with sand, alter drainage patterns and use temporary barriers to protect plants.

Some of the best plants with resistant characteristics include: Serviceberries, Honeylocust, white oaks, Japanese tree lilacs, Junipers, forsythias, hydrangeas and sumacs. Colorful perennials like daylilies, beebalms, sedums and Karl Foerster Feather Reed Grass will add allseason interest to your mailbox planting. Be more careful with: maples, river birch, crabapples, arborvitae, boxwoods and viburnums.

Building a Ledgestone Firepit

Step One: Gravel Base – Dig out the area for gravel base, planning for 4-6” depth of compacted gravel and diameter 3’ wider than your steel insert. Once soil is removed add your crushed limestone and compact every 2” layer.

Step Three: Block Layers – Use a concrete adhesive to adhere additional layers of block together being sure to stagger joints.

Step Four: Steel Insert – Install insert before adhesive hardens and you’re done!

Evaluate your Curb Appeal

Curb appeal is the first impression of a house. When done right the view from the street or driveway can put forth a positive and intriguing vibe. Research current landscape trends and hardy plant material or call in a landscape professional for a consultation to put together a plan that fits your time and budget to maximize the desired view from the street or driveway.

Beginning at the street the view includes the house itself but also the surrounding lawn, foundation plantings, trees or in some cases the lack there of. An appropriate balance of these landscape elements along with proper care to provide a neat and tidy look (but not blank and sparse) will provide that ideal first impression upon arrival. Often times a simple professional pruning and well placed plant addition can make all the difference.

Don’t let the overgrown shrubs bother you since they can easily be removed or cut down. Instead pay attention to problems like low spots or soil settling along foundations where water may be collecting and running into the foundation. Once you have evaluated problems start thinking about design!

Be sure to look at the front of your house from different angles and entry points such as view from the street, turning into the driveway focal point, walking up the side walk, front door entry waiting zone and don’t forget exiting your front door view to the street!

The Art and Wisdom of Japanese Gardens- karesansui

Dry Landscape Garden

This type of garden stone placement is modeled to look like the base of a mountain or hillside field. Where there are no water features present in nature or the maintenance of man-made water elements is not desirable this garden type can give you a similar look.

A wonderful example of this type of garden is located in Northfield MN on the campus of Carleton College to the east of Watson hall and up the hill from the tennis courts.

Jyo Ro En – The Garden of Quiet Listening – is a beautiful space that incorporates a mountain ‘stream’ cascading down to a wide ‘lake’ surrounded by lush vegetation carefully pruned to enhance the entire ‘picture’. The garden is viewed from the small pavilion and a path of stones directs you along the north edge of the garden.
