About this variety

Huge ruffled snow-white blooms on long stems with a good traditional scent. It is the standard white in the range and the one to grow if there is a wedding in the diary.

White has a practical use beyond weddings. Grown alongside coloured sweet peas it acts as the neutral that makes everything else read more strongly, and in a moon garden or an evening border it holds light long after coloured flowers have gone flat.

The one drawback of any white flower is that it shows every mark. Rain spots the petals and they brown, and a bloom past its best looks tired rather than gracefully faded, so cut it young and cut it often. That suits the plant anyway.

It is a vigorous Spencer to about two metres, flowering June through October, and it wants a proper support and the richest ground you can give it, with plenty of well-rotted manure dug in beforehand. Pick every flower as it opens. One pod allowed to set and the plant stops.
