Lizard's-tails
What are they?
Lizard-tails are rather primitive plants and are represented in our area by just a single native species, and an introduced one. The flowers are very small and would be inconspicuous were it not for the fact that they are densely arranged in elongated spikes. They spread by means of underground rhizomes, forming often quite extensive patches of vegetation.
Where are they found?
These are generally plants of wet, often shady, ground though, as a garden escape, Chameleon Plant could show up anywhere.
Identification
The two species found in our area are easily told apart by their very distinctive flower strctures. The zig-zag style of growth of their stems and leaves with heart-shaped bases are quite readily recognized once learned.
Lizard's-tail Saururus cernuus

Chameleon Plant Houttuynia cordata

Forst found in woods near Cape May Point in 2015, where probably originating from dumped garden waste. Flowers June to August or later. Flowers are greenish and arranged in a dense spike, above four, white, petal-like bracts.
