The earliest flowering rose around here is the burnet rose (Rosa
pimpinellifolia) (and perhaps also its hybrid with Rosa canina), with
Japanese rose (Rosa rugosa) (and perhaps also some of its hybrids)
following on.

I've have seen three other types flowering so far this year. One, with
resin-scented leaves and clear pink flowers, I suspect to be harsh downy
rose (Rosa tomentosa).

Of the other two, one has large (3-4") cream single flowers darkening
towards yellow at the base of the petals, and the other has dog rose
sized clear pink flowers, but lacks the resin scent of the leaves of
Rosa tomentosa and its allies. Does anyone know what either or both of
these are?
