Varieties of authentic early 19th-century plants are being grown, with names such as
Marvel of Peru, Dame's Violet and Bear's Britches.
A NO, the roots would not damage walls, and, yes, you can leave
Marvel of Peru (Mirabilis jalapa) in the ground, providing you have planted it in a free-draining soil in a sheltered spot.
Some, like roses and sweet peas - both of which can be planted now - need the sun to draw out their fragrance, while others such as night-scented stock and
Marvel of Peru (Mirabilis jalapa) wait until dusk or even the dark to release theirs.
