Paeonia rockii, from seed by Robert Pavlis

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: Hardy and Tropical Water Lilies for Ponds

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.

Iris Identification – Which Type of Iris Do I Have?

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 iris 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.

Hydrangea Identification

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 loose the name of a plant.
