Wild Single Flower Roses

Good morning !
I went to the botanical garden in Tokyo the other day.
Because it's a medicinal botanical garden, not only plants which beautiful flowers bloom, but there were many rare plants in the park.
The above picture is "Ross Rugosa" which is called "Hamanasu" of the original rose which grows naturally in Japan.
Like this picture, a large single flower of bright colors blooms.
Unlike luxurious modern roses, the rose of the wild species has a neat and clean charm.
