There is a very common myth that says, “nothing grows under walnut trees”, but that is far from being true. If you have walnut trees in your yard or the neighbors yard, you can still have a very lush garden and grow most things.
Yucca glauca, an agave, is the hardiest yucca growing from Alberta, Canada all the way to Texas. You will either love or hate this plant depending on your appetite for desert-like plants. I love them for their spiky leaves and fantastic flowers. They are extremely drought tolerant and easy to grow.
Paeonia rockii is a lovely tree peony that should be grown more. It can be difficult to find in a nursery, but those specializing in peonies will have it. The ones pictured here were grown from seed obtained from the Ontario Rock Garden Society Seedex program. The flowers are mostly white or light pink with dark maroon basal flares on the petals. There is some variation in flower form and coloration. One seedling from this group has red leaves in early summer.
The common name, tree peony, describes the woody stems that are produced, but it is probably more correct to call these shrubs, not trees. They do not need staking.
Water lilies (Nymphaea species) are extremely valuable to the pond. They not only look great and flower well, but the floating leaves provide shade, eliminating the light needed by algae. They also provide a hiding place for fish and other water creatures. Water lilies should cover half of the open water space to help maintain a balanced ecosystem. They do best in quiet water, so keep them away from fountains and waterfalls.
It might surprise you to learn that trees do get sunscald or sunburn and the remedy is not an SPF 30 lotion. Sunscald on trees usually happens on the south or south-west exposed bark. The bark is damaged and in severe cases can result in the death of the tree.
Historically, sunscald has been prevented by wrapping or painting the trunk of the tree. Do these preventative methods work? Are they still recommended? Time to have a closer look at the problem.
It is late June in the shady garden and out of nowhere appears a spotted finger sticking out of the ground. It grows quickly unfolding a huge tripartite shinny leaf. Each lobe is almost as large as my hand. But the real treasure is hidden below the leaf – a striped cobra that needs to be seen to be believed.
Iris are very common in the garden and often people ask for help to plant, grow, move or divide them. The answer to such questions starts with proper identification. There are many different species iris and they do not all grow the same way. Some have tubers and need to be divided regularly. Others are bulbs and hardly ever need to be divided.
Learning how to grow your iris starts with identifying the type of iris. I am not talking about finding out the actual cultivar name, but you do need to know which type of iris you are dealing with.
In this blog I will help you to identify the type of iris you have. In a future blog I will provide cultural advice for each type of iris.
Canada will celebrate its 150th birthday in 2017. To mark this celebration, Canada is launching a special tulip called ‘Canada 150’. The white and red colors of the tulip mimic the colors in our flag.
Where did the Canada 150 tulip originate? There are several stories floating around about its origin but much of this is not true. Canadians have been told that the tulip is only sold through a Canadian hardware stored called Home Hardware and is available in limited quantity. So it should be no surprise that ‘imposter tulips’ have been introduced into the Canadian market place. People will do anything for a loonie (the common name for our $1 coin).
Follow me as I try to unravel the mysteries of the special Canada 150 tulip and learn more about the confusing world of naming plant cultivars.
Why does my hydrangea not flower? This most commonly asked question about hydrangeas, especially in colder climates. The answer is not always a simple one but I’ll try to answer the question in this post.
Reasons for not flowering depend very much on the type of hydrangea you are growing. It is therefore important that you know the type. Have a look at Hydrangea Identification to find out which type you have.
Hydrangeas are very popular shrubs for the garden, but they can be a bit tricky to grow if you listen to all of the hydrangea myths on the internet and in books. In this blog, I will look at the truth behind some of the more common hydrangea myths. Once you have the facts, you will find that hydrangeas are easy to grow.

Are you wondering why your hydrangea is not flowering? Would you like to know when and how to prune your hydrangea? These are important questions, but no one can provide the correct answers until you know what type of hydrangea you have. This post will help with your hydrangea identification. It won’t provide cultivar names but it will identify the type of hydrangea.
It is always a good idea to keep plant names since it makes it so much easier to find the correct cultural information at a later date. But life happens and it is quite common for people to lose the name of a plant.
Planting trees seems like such a simple thing to do, but most of the trees I see have not been planted correctly. A couple of years ago I was teaching a course on trees and wanted a picture showing the right way to plant a tree. I could not find one with Google, which illustrates the lack of understanding among gardeners and professionals.
Most advice on planting trees is wrong.
Everything in the post applies to both trees and shrubs – shrubs are just short trees.
