Stately plant if slightly coarse in the floral department. The roots, it seems, can be used to produce a substance that kills the MRSA bacterium.
No problem after you get it growing.

Elecampane is a beautiful garden specimen with large spacious, light green pointed-tip leaves that does not appear to attract pests. Requires plenty of room to grow vertically, however, and probably about 5-6 feet laterally. Now reaching maturity in its 3rd year, I planted it on the northeast side of the garden next to a 4x4 about 7-ft tall in case staking was required. The bumblebees have adopted both the 4x4 and the elecampane. It's almost grown above the 4x4 and it's only May!

Very large velvety pointed leaves, cheerful yellow flowers in July. This plant gets about 7' tall for me, needs plenty of room. Herb used for respiratory problems, as antibacterial, and to aide digestion.
