Description

Laurentia or Isotoma 'Stella Pink' is a variation with pink flowers of an Australian plant also known as Solenopsis axillaris. Interesting for its texture and long flowering period, it forms a dense and rounded cushion-like clump with fine green foliage. Its small branched stems are covered with small pink star-shaped and slightly scented flowers from May to October. It is a very graceful and vibrant perennial plant that is cultivated as an annual in our climates. It can be grown at the edge of a flower bed or in hanging baskets and containers on the terrace and balcony.

Originating from Australia, Solenopsis axillaris is a herbaceous perennial plant with woody base that grows very rapidly and is often cultivated as an annual due to its lack of hardiness, but also because of its long and abundant flowering. It belongs to the family Campanulaceae. It quickly forms a branched clump that is naturally compact and nicely rounded, measuring 25 to 30cm (10 to 12in) in all directions. Its fine, narrow, tapered, deeply cut and toothed evergreen leaves are dark green. Between May and October, and even until the first frost, it produces countless small flowers with 5 pointed lobes arranged in a star shape. They are pleasantly scented. This plant is resistant to heat and drought, but will be more floriferous in fertile and moist soil.

Isotoma 'Stella Pink', little known but deserving a place in the garden as well as in pots and hanging baskets. Easy to grow and very floriferous, its delicate foliage and light star-shaped flowers make it an airy and decorative plant. It can be used en masse in borders or as accents among other plants in a flower bed. Combine it with other annual or perennial plants: pelargoniums, begonias, gypsophila, petunias. Plant it in rock gardens as well, with poppies, Osteospermums, small dahlias.

Planting and care

Laurentia requires very little maintenance and thrives in a sunny position. Plant it in the garden after the last frosts. Ensure that the plant does not lack water and remove faded flowers from time to time. Although it is water-efficient, it will be more floriferous and beautiful when planted in soil that remains slightly moist. In very mild climates, it can be a perennial, but it is advisable to overwinter the plant if you want to keep it from year to year. Repot it and keep it in a conservatory or cold greenhouse during winter. Attention: the sap of this plant can be irritating to certain individuals. Slugs and snails enjoy its foliage, so make sure to protect your young plants in spring.
