Our selection of Laurentia or Isotoma seeds. It includes superb varieties such as Laurentia 'Stargazer Mixed', a charming frost-tender perennial plant that offers small star-shaped flowers in a mix of white, pink, and mauve, or Isotoma 'Avant-Garde Blue F1 Hybrid' with pale blue, fragrant flowers from summer to autumn. Very floriferous, Laurentia is a perennial often grown as an annual, truly adorable in borders or flower pots. Let's not forget the varieties 'Blue Star' with deep blue flowers and 'Pink Frills' in pink, both distinguished by their remarkable performance.
Laurentia, also known as Isotoma, is a little-known plant with toothed leaves that stands out for its ability to produce a multitude of small star-shaped flowers throughout the summer. It is easy to sow and prefers well-drained soil and a sunny exposure to fully thrive. By planting Isotoma seeds, you invite a cascade of colour and light into your garden. Discover them in this selection.
