3 Creeping Mazus (Mazus reptans)
Delightful, miniature lobelia-like flowers in mauve-pink appear between neat green leaves in spring and summer. Hardy, it likes full sun and grows to 50mm high.
Why: They have a striking flame-like shape and come in vibrant shades of red, orange, yellow, hot pink, rose, mahogany and magenta. Theyâ€™re hardy and donâ€™t require a lot of water. Where: They love full sun and donâ€™t mind harsh winds, so theyâ€™re also ideal for coastal gardens.
How: Plant them in well-draining soil in areas that donâ€™t receive frost. Donâ€™t plant them with other annuals or plants that require regular watering, especially if youâ€™re using an automated sprinkler system. Deadheading will prolong their flowering season.
