Somehow my Google-fu is failing me on this. I've been trying with searches such as wildflowers bloom April Berkshire U.K. and only getting a few very common things (primroses, and late in the month, bluebells). I'm looking for common, fairly showy native species that might have been in bloom in April in the Roman occupation era south of modern-day Reading.
I've found various wildflower sites, but they seem to assume that you know the name of the plant already, or that you have a specimen and are trying to identify it.
I just need the names of a couple of additional flowering plants, and also any trees that are typically in bloom at that time of year in that region.
