A remarkable evergreen shrub given to me by Geoffrey Kibby who has had it in his North London garden for some time and reports that it has never been frost damaged and is very vigorous.
The suspicion is that it isn't parqui (sadly it has no evening fragrance for one thing) but the floral display is interesting enough on its own for me.
The flowers are essentially mustard yellow but heavily tinted with inky maroon, especially in bud and when they close up during the day, which creates a striking two-tone effect. The leaves are stained black in winter. Probably worth sheltering in colder areas.
