Rose Collection

Current status: Select rose varieties are now in their second,  lighter flush, following June’s abundant bloom. This two-acre garden combines roses with carefully chosen companion plants to lengthen the flowering season and promote a thriving, sustainable ecosystem. Currently, coneflowers, crocosmia, and phlox brighten the garden with a vibrant splash of colour.
