Tiny spikes of blue flowers adorn low carpet-like mats of green foliage on this resilient plant, which can take some light foot traffic; a superior groundcover selection, ideal in rock and alpine gardens, or cascading over walls
Tidal Pool Speedwell has masses of beautiful spikes of royal blue cup-shaped flowers with white eyes rising above the foliage from mid to late spring, which are most effective when planted in groupings. Its pointy leaves remain light green in color throughout the season. The fruit is not ornamentally significant.
Tidal Pool Speedwell is a dense herbaceous perennial with a ground-hugging habit of growth. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.
This is a relatively low maintenance plant, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.
Tidal Pool Speedwell is recommended for the following landscape applications;
Planting & Growing
Tidal Pool Speedwell will grow to be only 2 inches tall at maturity extending to 3 inches tall with the flowers, with a spread of 30 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 24 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 8 years.
This plant does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
Tidal Pool Speedwell is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
