I love primroses, and planted a couple of clumps of them in the adjacent border about 7 years ago. Since then they have escaped the border and now are rapidly colonising the path, seedimg everywhere. Nearby there are residents who are lovers of the brash polyanthus hybrids, and the resuts can be seen here. We now have pure white, dark yellow, red, and even bluish hybrids amongst the 'proper' primroses.
