Creeping Phlox 'Blue' (Phlox subulata)

Where to Plant:

This refers to a low-growing, mat-forming Phlox, often a variety of Phlox subulata. It creates a dense, evergreen carpet of foliage that is completely smothered in a mass of blue-violet flowers in late spring. It absolutely must have a position in full sun, as it will not flower well in the shade. The soil must be very well-drained, and it is perfectly happy in poor, gritty, or sandy soils. It is ideal for rockeries, the tops of sunny banks, spilling over walls, or edging a gravel path.

How to Plant:

You can plant container-grown plants at any time during the growing season. Dig a hole the same depth and width as the pot. Gently remove the plant from its container and place it in the hole, ensuring the top of the rootball is level with the surrounding soil. Backfill the hole, firm the soil gently around the plant, and water it in thoroughly to help it establish. Space individual plants about 30-45cm apart to allow them to spread and join up.

Aftercare:

This is a very low-maintenance plant. The most important task is to give the entire mat a light trim with shears immediately after it has finished flowering. This removes the faded flower heads and encourages the foliage to stay dense and compact, preventing it from becoming bare in the centre. Once established, it is very drought-tolerant and will not require any feeding.
