Lobelia pedunculata

Lobelia pedunculata is a perennial herb native to Australia and New Zealand that forms dense mats through underground stolons, creating a carpet of fine green foliage dotted with tiny, starry blue flowers from late spring through summer. It typically grows 5 cm high and can spread up to 100 cm, making it ankle-high and perfect for softening edges or filling gaps between paving slabs. This plant thrives in full sun to partial shade and prefers moist, well-drained soil rich in organic matter. It tolerates light shade but flowers best in sunny spots
