|What would be the best vine to quickly cover a chain link fence, and where would we get it?
|My suggestion would be to plant annual vines to cover your fence this year. At the same time, plant a few perennials that will mature in the next year or two. This way you'll have instant color from the annuals and a perennial (or two) coming along that will take of itself for years to come.
You might try morning glories or cardinal climber as your annual vines, and honeysuckle or trumpet vine as your perennial vines. Silver lace vine is a quick-growing perennial vine. If you're looking for an evergreen vine, you might try wintercreeper. There are lots of others to choose from...
Check out Burpee's selection of flowering vines (pp.42-43, 108 of the Spring 98 catalog). If you want to see plants before making a decision, go to your local garden centers in spring and summer and look at the plants. That way you can make an educated choice.
