Persicaria scoparium

Broom knotweed

This is a very curious plant that doesn't have any leaves. It produces a spray of branches from a woody stem. Each of these branches bear knotty bulges spaced at intervals. From these bulges or nodes spring  tiny little white flowers that resemble small stars. 

Extremely odd and rather captivating. 

It is found endemically on Corsica and Sardinia. Grow in any ordinary soil that is well drained in full sun. Needs water to establish and becomes drought tolerant with maturity. 

Hardy down to -10 or so.
