LAURENTIA

Isotoma axillaris is a heat-loving plant native to Australia that is hardy in zones 7-10 but is easily grown as an annual in colder climates. The common name laurentia comes from its previous classification as Laurentia axillaris; that name, as well as another synonym, Solenopsis axillaris, is still often used in the nursery industry. This species in the bellflower family (Campanulaceae) has other common names including blue star or star flower.

A profusion of star-shaped flowers are produced just above the foliage throughout the season until frost. The fragrant, 3cm wide flowers are produced in shades of blue, pink or white. The plants shed spent flowers on their own so do not need deadheading, although shearing in midseason will encourage more flowers on a more compact plant.

Grow laurentia in full sun to partial shade. Purchase plants in spring or grow from seed or cuttings. Seeds should be sown indoors very early Spring or late Winter as it takes about 4 months for the plants to come into flower. Place plants in the garden after the last frost. This plant has few pests, although it can be attacked by mealybugs, and is not favoured by deer or rabbits.

The cultivar illustrated here is "Pop-n-Fizz Glowing Purple".
