Hello where can I buy them in the Toronto downtown area?
For information on where to purchase agapanthus, select the garden centres closest to you.
This plant (or rhizomes) is usually available at large, well stocked centres that are known for having unusual container plants.
There are two types of agapanthus: deciduous and evergreen. The overwintering procedures differ.
If your agapanthus keeps its leaves after the summer, it is probably an evergreen. If the leaves die back, your agapanthus is deciduous. If you don’t know which you have, it may make the most sense to treat it as an evergreen, and you may be pleasantly surprised.
