Primroses are out in the garden, woods and lanes, a great, early source of nectar and pollen for over-wintering Butterflies (see photo). Buy one of these wonderful native plants, (or grow from seed), and split into many new plants every couple of years. In order to ensure cross-pollination, some Primroses have the female stigma at the mouth of the tube (Pin-eyed) and some have the male, pollen-covered anthers (‘Thrum-eyed’) at the top (see photos). Whichever is visible, further down the tube the opposite grows. So, a Butterfly or Bumblebee gathering pollen from visiting a Pin-eyed will automatically fertilise a Thrum-eyed, and vice versa. Conditions: Sunny intervals. Temperature: Max 8- Min 2C.
