Certain plants are more suitable for outdoor container growing than others. The best container plants should grow well with minimal effort from gardeners. Such plants include those naturally drought tolerant, plants that lack invasive tendencies and those that flower nicely with little in the way of additional water and fertilizer. The best plants will vary from region to region and under the care of different gardeners.
When given well-drained soil, adequate water and protection from freezing weather petunias will come back for several seasons from their roots as well as dropped seeds. Shearing the plants back when the blossoms begin to fade will promote a new blooming flush. Petunias prefer deep watering when the soil begins to dry. Heavy feeders while in bloom, a balanced water-soluble fertilizer applied at least monthly will promote many blooms.
Containing both perennial and annual types, the family Portulaca has a varied range of plants. Blossoms come in several shades, color combinations, and are available single, semi-double and double.

Experts recommend deadheading old blossoms for prolonged bloom time.
