Perennials for a Shady Location
 
There are many wonderful perennials suitable for a shady location. Most shade perennials tend to have interesting (even exotic) foliage and quietly elegant blooms   You will have greater success designing a shady garden if you focus on texture and foliage rather than flamboyant colour.  Perennials that are tolerant of dry shade are marked with a *.

Most perennials prefer a well drained location and their are many which are quite drought tolerant.  Drought proof your plants by practicing proper water techniques, ie water deeply and less frequently.  This will encourage plants to grow deep root systems which are then much less susceptible to drought.

Key requirements for attracting butterflies:
Stop using pesticides.  This is essential!!
o  Grow food plants for caterpillars and nectar plants for butterflies.
o  Grow larger groups of one variety of plant rather than solitary plants.
o   Include a water source in your garden.
o   Provide a spot where caterpillars and butterflies can over winter.
o  The bigger your garden, the better.

A quick way to attract hummingbirds is to put out a feeder.  Do not use food dye in the feeder as this can be very harmful to the bird.  You can now buy coloured feeders, but hummingbirds will learn to come to a clear feeder.  Be sure to change your feeder often, as in hot weather the solution will quickly go bad, ie. ferment.
Hummingbirds like tubular flowers but will also seek out cup-shaped or open circular blooms like the Delphinium and Hollyhock.  Bright colours -- especially red -- are always a favourite.

You would think that most flowers have fragrance but this is actually not the case.  If you would like scent or fragrance in your garden you must actively seek it out.  Scent may be found in a plant's blooms or it's foliage.  It can have many different dimensions from cloyingly sweet to a sinus-clearing camphor.  In any of its forms, scent brings another dimension to the garden, involving the visitor in a more intimate and private way than sight.

There can be huge variations in groundcovers, including:  height, speed of growth, durability, hardiness, and longevity.  Some groundcovers do well almost anywhere, but others have very specific growing requirements.  Know your site and the application before mass planting groundcovers, as selecting the wrong plant can be a costly and time consuming mistake.  Be aware that some groundcovers are very invasive, and once planted, will be difficult to remove.

 Also check out our on-line catalogue for many more suggestions.   Look under Groundcovers, Jeepers Creepers and Stepables.

Deer Resistant Perennials
 

Deer (and rabbits) will usually avoid plants that have fuzzy or prickly foliage.  They also tend to ignore foliage that is poisonous or has a pungent taste or smell.   Check out the website www.deerxlandscape.com.

Perennials that will Grow Under a Walnut Tree

Black Walnut tree roots produce a toxic substance called Juglone which can injure and kill plants.  Usually the first sign is leaf wilt which usually occurs in a relatively short time after planting.  If the toxic effect is detected early and the plant removed it may recover in a new location.  At later stages the wilting becomes severe and the leaves turn brown resulting in the death of the plant.   Many perennials are not effected by Juglone and can be grown under and close to walnut trees.   Most native plants will do well under a walnut.  Experiment as this is by no means a conclusive list.  Watch for signs of wilting in the first few weeks after planting and move the plant immediately if effected.  (Make sure the wilting is not the insufficient watering.)
