Mermaid' is a rose for special situations.
Growth habit is aggressive to say the least.
Growing easily to at least twenty feet, 'Mermaid' is useful for covering large expanses of space, for example, an unsightly brushpile. It would also be useful as a hedgerow bordering a property line. This rose is most definitely not for the faint of heart, as like Wisteria, it's shear vigor will overwhelm anything that gets in its way. Attempting to prune to a smaller size is not recommended as it will spring forth immediately with aggressive new growth, and the thorns are nasty, hooked affairs. If you do have some wide open spaces which could be a home for 'Mermaid,' the rewards of growing this plant are significant.
