White waterlily.
Moving into the water now, here is a common plant that frogs love to sit on. White or European waterlilies are invasive in North America, being found originally in Africa, Europe and Asia. The large lilypads can be seen from space, framing in the very rectangular dredged shape of Burnaby Lake in satellite images while the more organic glacial shape is seen in maps and in the winter.
This painting is a watercolour painting by Michelle Wiebe (@seachelle_paints).
