are aspen trees weeds?

a weed is any plant that you do not want, so if you have a rose bush that is not wanted it could be considered a weed. \n\nSo if you want your Aspen tree then it is not a weed, if you don't want it, it is.  However as it is a tree it might have a preservation order put on it so do not cut it down without checking with your local authorities.

Lots trees bloom first, then leaf out. Most of our spring flowering trees in the East and Midwest, most fruit trees, etc...Think of all the decorative trees...Dogwoods, redbuds, flowering peach, Almond, crab apple, etc. ...all bloom, then leaf out.

The definition of a weed is "a plant out of place" so theoretically any plant species could be considered a weed if it is growing in an undesireable location.

The word dogwood is not exactly an appealing name for such a lovely tree. Just how did the plant get is name? There are many stories. In Europe, the bark from a dogwood species was used to make a treatment for mange. Perhaps, the name came from dagwood -- dag being an old name for a meat skewer. From the colonist viewpoint, may have comes the name dog tree - bearer of worthless little fruit refereed to as dog berries.

Kudzu and pretty much anyother plant...  I would suspect most of the 'creeping' vines would be considered predatory.

The Cypress has leaves and a Juniper has needles - more info on both below\n\nThe bald cypress is found in marshy areas in the United States. The Cache Wetlands is an example in Southern Illinois where to find this imposing tree.\n\nThe bald cypress knees can be seen sticking out of the water like stumps. The leaves on a cypress tree are light green in spring and are dark brown in the summer time. The bark on the bald cypress is light gray to cinnamon red.\n\nThe bald cypress is so durable even the Indians used the tree. Sometimes the Indians would use the bald cypress for dugout canoes. \n\nJuniper One of the characteristic heathland shrubs of the chalk and limestone country is the Juniper - Juniperus communis. The shrub typically grows from 4 - 6 feet high with the trunk or stem often being contorted and twisted. The leaves take the form of needles of a deep green colour sometimes with a bluish-tinge, on account of which it is often known in folk tradition as the needle yew. The berries usually take two to three years to fully ripen, hence it is common to see both the bluish-black ripe berries alongside very green and under-ripe ones on the same bush. When fully ripe, the berries are about the size of a pea and have an aromatic resiny scent.

The tree is indeed cllaed thunderwood, the alternative name is posion sumac. It is every bit as nasty as your reltives describe.\n\nOne author describes this poison as "a violent skin irritant," and he says that "Some persons are more susceptible to the poison than others." Another author describes this as "One of the most dangerous North American plants [that] for many people, causes a rash upon contact." And it must be noted that any contact from the Poison Sumac with eyes, mouth, or nostrils would be extremely dangerous! In any case, a person who even suspects contact with any part of the Poison Sumac plant should wash the exposed skin at once and thoroughly with strong soap and water. A physician's advice should be sought as well.

no ... bamboo is classed as a GRASS, not a tree. Deciduous trees loose their leaves in autumn/fall.

In beet plants where coal or oil is employed as fuel, NOx and SOx are potential pollutants. Additionally, in beet factories with pulp drying equipment, the chimney discharge problems associated with the fuel being used are supplemented by an odour problem due to sugar destruction and similar processes in the drying plant.\nhttp://www.sucrose.com/environment.html\n\n\nsulphur dioxide (SOx); http://www.ec.gc.ca/cleanair-airpur/SOx-WSBBB2123F-1_En.htm\nnitrogen dioxide (NOx); http://www.ec.gc.ca/cleanair-airpur/NOx-WS489FEE7D-1_En.htm

Hygrophila balismica has been reported to be poisonous, but it grows at the surface, as does Water hemlock.\n\nIn a search of over two dozen texts and references and several hundred web sites, I could find no report of a toxic plant which is entirely under water except algae (called dinoflagellates) and others which cause red tide and similar blooms (called Harmful Algal Blooms).\n\nI'm not saying there are none, just that I am having trouble finding them.

Check by visiting the website lists of reputable seed companies such as Thompson and Morgan. Any restrictions on the supply of seed to specific countries will be posted there.  I can't imagine why Canada would choose to proscribe this plant, in the UK it is a common  native weed  but not invasive or an ecological threat.\nWhy would you want to grow it anyway? I spend too much time pulling it out!
