Annuals are usually grown to provide color. Since they are only temporary plants in many gardens – if they are always treated as such, they tend to thrive anywhere. Annuals permit gardeners in cold areas to briefly ignore the prospect of inter bleakness and inject a touch of tropical summer color into their gardens.

Annuals are subject to all the normal climatic considerations – wind, salt spray, and summer heat – but they are remarkably resilient plants that carry on flowering under most conditions, except severe cold.

Tender annuals must be planted in spring, after the last frosts, with a view to summer and autumn flowering. However, the so called hardy annuals are often planted in the autumn and left to over-winter for spring flowering. Pansies, Sweet William and Iceland poppies are among the best known hardy annuals. It’s true that the majority of my Pansies (provided they survive the heat of summer), Sweet William (pinks, dianthus) and Iceland poppies often do survive our Canadian zone 6B/ USD zone 5B winters.

With careful planning- depending upon your zone of course, it’s possible to have blooms almost all year round. I tend to have blooms outdoors in my garden from perennials, annuals, bulbs and rhizomes from Mid-March well into November; and indoors my plants such as Thanks Giving and Christmas Cactus, Jasmine and amaryllis give me blooms inside through November to March.
