| The flowers have five narrow white petals (best seen lower right), and are narrower than those of Butterbur. The plants with male flowers are distinguished from those with female flowers by the five-petalled star with elongated stamen. |

| White Butterbur has long and pale-green sepals whereas in normal Butterbur they are much shorter (the Author thinks, but is un-sure of the white-coloured Butterburs lower down the page). |

| This and the above photos are all of the much commoner male form of White Butterbur. |

| The leaves are different to those of Butterbur, although of similar cardiod outline, they are loner, and some have a distinctive arrow-head shape. The flower spikes can be reddish. It is possible that this and all the following plants are all of the rarer female form of White Butterbur. |

Grows in similar places to Butterbur (damp woods, beside streams and fresh water). Many similarities to : Butterbur but that has mauve to purplish flowers whereas White Butterbur has all white flowers.

Not to be confused with :
No relation to : White Butterbur is an introduced plant, grown in gardens, but now also growing wild, mainly in the North of the UK, especially in Scotland. Just like Butterbur, the male and female flowers of White Butterbur occur on separate plants, with the female plant being much the rarer. The author assumes that the above two differing forms represent both male and female of the same species. It is rare in the south of the UK, but frequent in the north, especially in Scotland. |
