Powdery Alligator-flag Thalia dealbata - 1L Pot

The Thalia dealbata is an aquatic plant that can grow up to 6ft in height. A panicle above the foliage supports its small violet flowers, and its blue-green leaves have attractive purple edges. It is a truly dramatic plant that will add height and colour to your pond. This plant is half-hardy but it should grow without any trouble in the southern regions of England. In colder parts of the UK it might lose its foliage during winter, although it can be overwintered in a greenhouse.
