The plant-umbrella resembles the domestic instrument of that name; but, instead of the ordinary handle, has a pointed rod, shod with iron, for insertion in the ground. It is used for shading tender plants from the sun, or sheltering them from the rain.

It is much used in the Paris garden, and at Monza, in Lombardy.
