FLOWERING SHRUB. Eunonymus japonica is a favourite evergreen hedge plant growing to 20 ft. It does well in seaside gardens. £. europaeus is the deciduous spindle tree with orange fruits. It is a host plant for the black fly of broad beans, eggs being laid in winter on this shrub. This species is very tolerant of chalk and lime. It is highly susceptible to attacks by ermine moth caterpillars which should be tackled by Pyrethrin sprays.
