Perennial grasses can be propagated by seed sown in spring or autumn. Established clump-forming plants can be lifted and split in the spring. Grasses that form rhizomes can be propagated by cutting the rhizome into sections, each with at least one growing point, then potting up into individual pots of free draining compost. The rhizome should be covered to the same depth as when it was lifted from the mother plant.
Most grasses require very little after care, as long as plenty of organic or fibrous matter is incorporated to dry sites to help retain adequate moisture. The soil should not, however, be high in nutrients. If too much water is a problem, increase the drainage by mixing sharp grit or sand into the soil or try growing sedges or rushes.
The mixed perennial flowering grasses (Seed Catalogue number 9880) contains a mix of some or all of the following grasses:
This grass is an ideal ground cover or rockery plant. It grows in a tufted clump and is 15 - 30cm (6-12m) high. It is a true azure blue in colour.
Hair Grass is a tufted, glaucous, semi-evergreen grass. It is ideal for the front of a border or rockery growing to about 20cm (8in).
Melick has densely flowered tips in the summer. It is a clump-forming grass growing from 10cm to around 23cm (4-9in).
Feather Grass makes a very good dried flower for display work. It grows to about 75cm (30in).
Feathertop Grass is a loosely tufted grass with bristly plume-like flower heads. They slowly turn purple as they mature. The grass is sometimes grown as an annual plant.
The quantity of seed in the pack should give you approximately 30 to 45 plants.
