As climate change erodes the familiar pattern of the seasons, we turn instinctively to the life cycles of herbaceous plants to guide us through the year.The growing, flowering, seeding and dying back of wild flowers, weeds, herbs and garden perennials sustain and enrich our lives.Herbaceous is a journey which follows the colour pulse of plants through the year, looking for the new and emerging rhythms.Beginning with the bright yellow, followed by the vernal whites of spring and the pinks of summer, the blues of early autumn and finally the browns of seeds set as winter comes.Herbaceous is gardening with words - asking us to look again at our relationship with plants and celebrates their power to nourish our spirits.
