Persicaria Decipiens
''Persicaria decipiens'', commonly known as slender knotweed, is a species of flowering plant native to Australia and Asia. ''Persicaria decipiens'' is a trailing plant whose stems grow horizontally at first but become more vertical with time, reaching high. Its narrow elliptic to lanceolate (spear-shaped) leaves are long and across. The slender pink flower spikes appear from November to June, with a peak in February. Cylindrical in shape, they are not stiff and tend to bend over. The plant tends to die back in winter and regenerate after water. ''Persicaria decipiens'' was among the plants collected by Joseph Banks and Daniel Solander on 5 May 1770 at Botany Bay during the first voyage of Captain James Cook. Prolific Scottish botanist Robert Brown described the species as ''Polygonum decipiens'' in his 1810 work '' Prodromus Florae Novae Hollandiae et Insulae Van Diemen''. It was given its current name by Karen Wilson Karen Louise Wilson (born 1950) is an Australi ...
