I would like some help in determining what to plant in my yard.
Questions of this nature are beyond a phone call consultation and it depends on the scale and nature of your project as to where you could go for further help. The most important consideration is the soil moisture and aspect. If your site is dry and hot you need to consider the use of xerophytic plants that love those conditions and you will not have to water such a landscape. Visit the Gosling Wildlife Gardens at The Arboretum for ideas on wildlife friendly gardening.
Fill your garden with plants that you like. Visit The Arboretum at least once a season and take note of the plants that stand out for you. They are labeled and that allows you to read about the ones that draw your attention. If the site you have will support the plant you are interested in, then search out a nursery/garden centre or plant sale that offers that species or variety.
School yard and community projects can make use of the resources at the Evergreen Foundation. Schools in particular should consider the environmental curriculum framework designed by the Toronto District Schoolboard that focuses attention on sense of place, ecosystem thinking and human impact.
