MGAA: Spring Symposium (On-Line)

Feb. 28th  9-3:30

Speakers:

Wilbert Ronald of Jeffries nurseries: Columnar Trees

Columnar trees are extremely popular accent and screening trees in the flat Canadian prairies. In recent years the Columnar Swedish aspen cultivar was among the most popular of columnar trees but it has lost its position due to disease and introduction of other new trees. A number of newer columnar trees including columnar flowering crabapples, columnar Parkland Pillar birch and other trees are coming to the forefront.

John Acorn, Naturalist: Butterflies in the Garden and Beyond

There are more than 170 species of butterflies in Alberta, and many of these are familiar garden insects.  Gardening for butterflies involves the use of both nectar-source flowers to attract the adults, and caterpillar food plants to sustain the larvae.  Naturally, most types of pesticides should be avoided.  Monarchs are of course the most popular of the Alberta species, but in truth they are almost entirely limited to the southern centres such as Medicine Hat and Lethbridge.  And if the garden butterflies are an inspiration to you, you might also enjoy pursuing butterflies farther afield, in environments that are difficult to replicate in a managed garden.
