Chaenomeles spp. - Flowering Quince
(Rosaceae)
-----------------------------------------------------------------------------------
Chaenomeles is a functional flowering hedge, border,
or specimen shrub that can be used near buildings.
The major appeal of Flowering Quince is its showy
but brief flowering period. The rest of the year it’s a
utilitarian thorny shrub with limited aesthetic
attributes.

cultivars
