The Story

Plant Bio

A low-growing, mat-forming perennial that spreads by runners to create a dense carpet of tiny green leaves. It is covered in a profusion of small, star-shaped flowers for a long period. It is an excellent lawn substitute in small areas and is perfect for planting between stepping stones as it tolerates light foot traffic. The tiny, sky-blue flowers create a beautiful, delicate effect.

Bloom Period:

EarlyLate

Uses & Benefits:

Creates a lush, green carpet studded with thousands of tiny, star-shaped blue flowers from spring through summer. It provides a soft, fine-textured look that is ideal for filling gaps between pavers or as a small-scale lawn alternative.

Its ability to tolerate light foot traffic makes it highly functional for pathways and patios. It spreads quickly to fill in bare spots, helping to suppress weeds and reduce the need for mulch.

The dense mat provides a micro-habitat for beneficial insects and spiders. The flowers, though small, offer nectar to tiny native bees and other small pollinators.

Prepare the area by removing all weeds.
Plant plugs 6-12 inches apart.

Keep It Thriving

Care Guide

Do

Provide regular water, especially in full sun.
Plant in a location where its spreading habit is welcome.
Use it between stepping stones where it can be appreciated up close.
Divide in spring if patches become thin.

Don't

Do not let it dry out, which causes brown patches.
Avoid planting near delicate, slow-growing alpines it might smother.
Be aware of its potential to spread aggressively into lawns.
Handle with gloves if you have sensitive skin.
