The Heritage Late Flowering 80% Grass Mix Wildflower Seed is a specialist blend of UK native wildflowers and low-maintenance grasses designed to provide vibrant colour and ecological value later in the flowering season. With an 80/20 grass-to-wildflower ratio, this mix is ideal for councils, contractors, landowners, and professional gardeners looking to extend flowering displays into late summer and early autumn—maximising visual impact and biodiversity support.
Specifically tailored for meadows, verges, parks, and naturalised landscapes, this late-season mix includes species such as Selfheal, Autumn Hawkbit, and Clustered Bellflower—perfect for attracting bees, butterflies, and other pollinators after most early-season species have faded. It performs well on a wide range of soil types and is part of the John Chambers Heritage Range, developed to reflect and restore Britain’s native flora.
All wildflower seed mixes are subject to change, dependent on time of year, harvest, and may include more species than listed above.
