‘Twombly’s Red Sentinel’ is a great introduction discovered as a witches broom on a 'Bloodgood' by Ken Twombly of Twombly Nursery, Monroe Connecticut. Much more vigorous than most witches brooms, 'Twombly's Red Sentinel' quickly develops the upright columnar habit for which it has become famous but will widen some with age. New leaves appear crimson red then quickly darken to burgundy but as this plant almost always seems to be growing it has a two toned effect most of the year. Fall color is a spectacular red and the dark red stems of the last new growth even add interest to the winter landscape.
