Cultivation
Many poplars are grown as ornamental trees, with numerous cultivars used. They have the advantage of growing very big, very fast. Almost all poplars take root readily from cuttings or where broken branches lie on the ground.
Trees with fastigiate (erect, columnar) branching are particularly popular, and are widely grown across Europe and southwest Asia. However, like willows, poplars have very vigorous and invasive root systems stretching up to 40 m from the trees; planting close to houses or ceramic water pipes may result in damaged foundations and cracked walls and pipes due to their search for moisture.
A simple, reproducible, high frequency micropropagation protocol in Eastern Cottonwood Populus deltoides has been reported by Yadav et al. 2009

Famous quotes containing the word cultivation:
“Those who are esteemed umpires of taste, are often persons who have acquired some knowledge of admired pictures or sculptures, and have an inclination for whatever is elegant; but if you inquire whether they are beautiful souls, and whether their own acts are like fair pictures, you learn that they are selfish and sensual. Their cultivation is local, as if you should rub a log of dry wood in one spot to produce fire, all the rest remaining cold.”
—Ralph Waldo Emerson (1803–1882)
“... in the education of women, the cultivation of the understanding is always subordinate to the acquirement of some corporeal accomplishment ...”
—Mary Wollstonecraft (1759–1797)
“If the minds of women were enlightened and improved, the domestic circle would be more frequently refreshed by intelligent conversation, a means of edification now deplorably neglected, for want of that cultivation which these intellectual advantages would confer.”
—Sarah M. Grimke (1792–1873)
