The 45-year-old actress, who was married to Liam Neeson, died in March (09) following a skiing accident in Montreal, Canada.
Family and friends of Richardson have been planning a way to honour her memory - and they've decided on a floral tribute.
One anonymous pal tells Britain's Sunday Express newspaper, "We all want something to remember Natasha and there's no one who better resembles a perfect English rose than her. The whole family loves the idea of having a rose named after her."
