Description
In our climate Laurentia (Isotoma) is grown as an annual. It belongs to the bellflower family (Campanulaceae).
Its decorative star-shaped flowers can be blue, pink or white. They cover the plant profusely from spring to autumn. Its delicate leaves add to its charm. Laurentia grows up to 30 cm tall.
It is recommended for balcony boxes and is excellent in hanging containers. It can also be grown in borders and rock gardens.
Requirements
Give Laurentia a sunny position and fertile, free-draining compost.
Propagation
Sow the seeds in March–April in trays or cell trays. Do not cover them – just press them into the compost with a small board. At 16–20°C they come up after 14–20 days. Plant out in the final position in May, once there is no longer any danger of frost.
Care
Grow in a sunny spot in fertile, free-draining compost with added clay. Plants grown in containers can be overwintered in a bright room at 10–15°C.
