What does a purple loosestrife need to survive?

Answer 1

i thinkPhylum or Division: Anthophyta

Class: Magnoliopsida

Subclass: Rosidae

Order: Myrtales

Family: Lythraceae

Identification: A perennial herb of moist or marshy sites, 1-2 meters tall, stem square or sometimes six sided, smooth or more often with short upward pointing hairs. As many as 30 to 50 branches emerge from a large root crown that becomes woody with age. Leaves are opposite or borne in whorls of three, sessile (attached directly to the stem), lanceolate to nearly linear 3-10 cm. Purple-magenta flowers are showy, 7-12 mm, 5-7 petals, on a terminal spike 10 to 40 cm tall, appearing from July through September. Styles and stamens are trimorphic. Stamens number mostly 12, alternating shorter and longer. Sepals, green outer floral leaves, are fused, forming a tube around ovary. 2n= 30, 50, 60. Mature plants can produce more than 2 million 1 mm long, reddish-brown seeds per year.

A closely related exotic, though not invasive, species, L. virgatum, is established locally in MA and new England as a local escape from cultivation, and is distinguished from L. salicaria by its smooth stalk and leaves that narrow towards the base.

Two other similar species are Northern willowherb (Epilobium ciliatum) and hairy willowweed (Epilobium hirsutum),which may resemble purple loosestrife seedlings and root sprouts, though in fact both are annuals and much smaller. Northern willowherb may be distinguished by its round stem and smaller, fewer pink flowers with only 4 petals; hairy willowweed is similar, but with long spreading hairs.

Original Distribution: Two centers of distribution within Eurasia are known, one stretching from the British Isles, with its northern limit near the 65th parallel, including a portion of Norway's North Sea coast, through southern Sweden, Finland and into Russia, with the southern limit of its range extending through southern Europe, Italy, the balkans, and Greece to the Bosporus straits, then along the west, north and eastern shores of the Black Sea, and east to the west shore of the Caspian. Around the Mediterranean, some occurrences in northern Morocco, and coastal Algeria. The Asian segment of distribution, characterized by smoother, less hairy stems, is centered in Japan, extends east to the Amur river, and south through the lowlands of China into Southeast Asia and northern India. The arid lands of western Mongolia, China and Tibet form a large gap between the two segments.

Current Distribution: From its Eurasian distributions above, L. salicaria has expanded in the northern hemisphere to a circumpolar distribution, and is now common in the temperate regions of North America, from New Foundland and Quebec to North Dakota, south to Virginia, Missouri and Kansas. Also found in scattered pockets along the Pacific Coast, and in the arid west as a weed of irrigation trenches. In addition, L. salicaria has invaded temperate subtropical areas such as eastern Ethiopia, New Zealand, Tasmania and Australia.

Answer 2

Purple loosestrife requires full sun, moist to wet soil, and space to grow freely in order to thrive. It is an invasive species in many regions, so care should be taken to prevent it from spreading uncontrollably.

Answer 3

it need soil and sun and oxygen :P # swaahg <3
