The new Rockies Helleborus series includes four named selections—Mount Nebo, Pike’s Peak, Grand Teton, and Snowshoe Mountain—each offering unique foliage and floral characteristics. These compact, mounded plants are designed for part to full shade and are hardy in Zones 6 to 9.
With richly coloured leaves, speckled patterns, and long-lasting blooms that emerge in late winter to early spring, the series extends visual interest well into summer. Highlights include the rose-tinged foliage and chartreuse flowers of Snowshoe Mountain, the deep burgundy blooms of Grand Teton, and the silvery overlays seen in Pike’s Peak.
Aconitum carmichaelii ‘Pershore Abbey’ and the Rockies Helleborus series will also be launched at the show.

‘Pershore Abbey’, a striking variety of Aconitum (Monkshood or Wolfsbane), offers lush green foliage topped with vibrant purple flowers from summer into autumn. With a mounded habit and an upright height of about 80 to 90 cm, it thrives in full sun and is hardy across USDA Zones 3 to 8. This perennial is ideal for well-drained meadows or cottage gardens and brings long-lasting seasonal colour with excellent cold tolerance.
General manager Justin Wisniewski said: “For nearly 35 years, Must Have Perennials has been introducing some of the finest perennials in the industry. We’re seeing a renewed interest in gardening and naturalism, and our latest introductions reflect that trend. Four Oaks gives us a valuable opportunity to connect with our UK partners and showcase these exciting new plants.”
Must Have Perennials welcomes visitors to Booth C21 during the show.
