Bacopa ( Sutera cordata) is now one of the most popular annuals (perennial in mild climates) for containers.
Its trailing habit, long bloom season, and copious small flowers make it a choice plant for cascading over the edges of patio pots, window boxes, and hanging baskets. New flower colors, including lavender and brick red, have joined the more familiar white 'Snowflake'.
This year there's also a delightful blue-flowered variety, called 'Blue Showers', from Paul Ecke Ranch; it's sold under the Flower Fields label. In the container pictured at right, it pairs with Swan River daisies ( Brachyscome 'Mauve Delight' and 'Jumbo Misty Pink') and Salvia x sylvestris 'May Night'.
Bacopa is a thirsty plant. Keep it well watered, especially during hot weather, and give it partial shade. Feed every two weeks with an acid-type fertilizer.
