Jack-by-the hedge!

| [Note Guidelines] Photographer's Note |
This plants colloquial name is "Jack by the hedge" but is Garlic Mustard!!!Alliaria petiolata
Member of the Cabbage Family.
One of the most commonest of the spring hedgerow plants.
Medium/tall biennial. it does smell of garlic when crushed. The plant is "hairy" below.
The flowers are only about 5-7mm across, delicate, and tightly bunched at the stem ends. These form a cluster of flowers that make this plant stand out on sunny days. The rest of the plant is a bright shiny green on the leaf.the leaves being almost heart shaped and toothed.
They flower between April/June before forming a seed pod about 3-7mm long. They prefer light shade on hedgebanks and in woods.
This plant is technically an invasive species, and in the USA it can become an ecological threat.
Garlic mustard poses a severe threat to native plants and animals in forest communities in much of the eastern and Midwest U.S.
Many native wild flowers that complete their life cycles in the springtime, such as spring beauty, wild ginger, bloodroot, Dutchman's breeches, hepatica, toothworts, and trilliums, occur in the same habitat as garlic mustard.
Once introduced to an area, garlic mustard out competes native plants by aggressively monopolizing light, moisture, nutrients, soil and space.
Wildlife species that depend on these early plants for their foliage, pollen, nectar, fruits, seeds and roots, are deprived of these essential food sources when garlic mustard replaces them. Humans are also deprived of the vibrant display of beautiful spring wild flowers.
Garlic mustard also poses a threat to one of the USA's rare native insects, the West Virginia white butterfly (Pieris virginiensis). Several species of spring wildflowers known as "toothworts" (Dentaria), also in the mustard family, are the primary food source for the caterpillar stage of this butterfly. Invasions of garlic mustard are causing local extirpations of the toothworts, and chemicals in garlic mustard appear to be toxic to the eggs of the butterfly, as evidenced by their failure to hatch when laid on garlic mustard plants.So, not such a hot plant then!!
This one was imaged on a South facing, but shady bank. The area is usually moist most of the year, but it drains well preventing waterlogging.
