Saponaria Plant – The common names of Saponaria (Soapwort, Bouncing Bet) are a guide to some of its properties. Stir a handful of cut leaves in a bowl of water and the lather produced reveals why it is called Soapwort. Leave a clump to grow undisturbed in the border for a few years and the sight of its stems springing up amongst other plants reveals why it is also called Bouncing Bet.
It is really too invasive for the choice border, but it remains a charming cottage garden plant. The erect stems bear lance-shaped leaves and in summer a terminal cluster of flowers. It is completely trouble-free – merely out down the stems to ground level in the fall.
Varieties of Saponaria
Thespecies grown in gardens is Saponaria officinalis (height2-3 FT, spacing 2 ft, flowering period JuIy – September). The pink single- flowered species is one of our native flowers, found wild in hedges and woodland, as well as being a popular plant in cottage gardens, but it has now been largely superseded by the double-flowering varieties – ‘Rosea Plena’ (pink), ‘Rubra Plena’ (red) and ‘Alba Plena’ (white).
