I manage an apartment complex and am supossed to plant annuals each spring. The landscaping was redone at the end of last season so we are experimenting with what flowers we should plant. I was given the idea of calibrachoa to go around some large rocks to cascade down around them. There are two large rocks with planting space between and around them. I don't know if this is as low and cascading as I thought it would be. I don't know what would work well there. I was also told to use zennias behind the calibrachoa. Any suggesstions would be very much welcomed.

Some annuals that do well in the sunny areas of Colorado are cleome, zinnia, marigold, flowering tobacco, sunflower and snapdragon. Annuals of medium height that perform well in sunny locations are dahlia, geranium, marigold, snapdragon and Victoria salvia. Some short, sun-loving annuals include petunia, marigold, vinca, verbena, gazania, alyssum, nasturtium and portulaca. Some shade lovers include impatiens, begonia, lobelia and coleus. All come in several colors and heights. You might want to try several annual vines including the black-eyed Susan, cup-and saucer, If you're looking for trailing plants, think first of nasturtiums, and moonflower.

The black-eyed Susan grows to a height of seven feet in partial to light shade and moist soil. It has yellow, orange or white flowers with dark centers.

Cup-and-saucer vines grows 20 feet in semi-shady to sunny locations and moist soil. They bear reddish-purple flower cups in green saucers.

The moonflower vine may reach 20 feet in a growing season. It will grow in poor soil, but needs a sunny location. The large, fragrant white flowers open at night and close by mid-day.

You also might want to consider nasturtium, scarlet runner bean, hyacinth bean, sweet potato vine, hops and morning glory.

There are so many annuals to choose from! Best wishes with your garden.
