The prolific multiplication of Cistercian monasteries of women in the Low Countries obliged the White Nuns to turn to the newly founded friars, disciples of Francis and Dominic, rather than to their brother monks, for spiritual and sacramental assistance. Lutgarde was a friend and mother to the early Dominicans and Franciscans, supporting their preaching by her prayer and fasting, offering them hospitality, ever eager for news of their missions and spiritual conquests. Her first biographer relates that the friars named her "mater praedicatorum", the mother of preachers.
