Description
Isotoma fluviatilis 'Blue', commonly known as blue star creeper, is a charming, low-growing perennial that’s perfect for adding a soft, carpet-like effect to your garden. Forming a dense mat, this creeping plant quickly fills in gaps, offering delicate star-shaped flowers in pale blue. Isotoma fluviatilis 'Blue' is the ideal choice for rock gardens or those tricky cracks between paving, where other plants might struggle to thrive. Its spreading habit and tiny blooms bring a touch of magic to areas that need a bit of greenery and life.
While Isotoma fluviatilis 'Blue' is a quiet achiever, it certainly makes its presence known in the most subtle way. This hardy perennial thrives in well-drained soil and a sunny spot, where it will happily spread over time, creating a beautiful, low-maintenance ground cover. Its ability to tolerate dry conditions makes it perfect for planting in crevices or along paths where water may be scarce. The pale blue flowers of Isotoma fluviatilis 'Blue' add an air of tranquility to your garden, making Isotoma fluviatilis an excellent choice for those looking to soften the edges of a rock garden or create a charming, naturalistic look between paving stones.
Our Isotoma fluviatilis 'Blue' plants are supplied as a root ball with healthy growth, ensuring a strong start. They are carefully shipped in our unique cardboard box, designed to keep them safe and in top condition. This ensures they arrive healthy and ready to thrive in their new home.
Isotoma fluviatilis is called blue star creeper for its tiny, star-shaped blue flowers that happily creep between paving stones like garden confetti.

Useful information
-
Soak your Isotoma fluviatilis 'Blue' roots in water for 3-6 hours prior to planting.
Plant your "Blue star creeper" bare roots into temporary pots with a multipurpose compost in spring and grow-on in a sheltered spot outdoors.
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed.
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
