Lycoris (Spider Lilies) are grown for their showy funnel-shaped flowers with narrow, spreading, sometimes reflexed petals, borne on leafless stems from spring to early autumn depending on where you live.   It can often be a difficult species to get into flower because it requires a hot dry resting period during summer to promote flowering but will develop into large clusters if left in the same location for a number of seasons.  All varieties are deer resistant.  In areas with hot summers, grow them in a sunny border or rock garden.
