2 Growing in clumps
Make sure you use the best-behaved clump-forming ornamental grasses such as fountain grass (pennisetum). Another good choice is the Japanese blood grass, Imperata cylindrica ‘Rubra’, producing blood-red spikes that fade to bright green at the base and become translucent by late summer. Plant it alongside the white-edged hosta cultivar ‘Francee’ for good effect.
