Semi Hardy
‘Semi Hardy’ corresponds to RHS Hardiness Rating: H3, with plants tolerating a Winter Minimum Temperature Range: 1 to-.5
Plants described by us as semi hardy should survive winters in mild parts of UK (including sheltered coastal areas) except in severe winters or when sudden early frosts occur, when the plant may not survive. Semi-hardy plants may survive winters elsewhere with the protection of a south- or west-facing wall or in a sheltered microclimate e.g. an inner city garden.
