"Numerous horticultural plants owe their beauty to the fact that they are grafted or budded onto a standard, especially those that have a weeping or cascading form...In most cases, multiple scions are grafted or budded 3 feet or higher on the main stem of the rootstock. When used this way, the rootstock is referred to as a standard...

Standard - a single-stemmed understock used for the production of weeping forms of woody plants. One or more scions are usually grafted relatively high on the understock (2 to 6 feet).
Top-worked plant - an established tree or mature plant whose upper portion has been removed back to the main limbs or trunk and then grafted with new scions"

"Plants with a weeping growth habit are often grafted or budded onto a standard rootstock. It may require staking for several years until the standard is large enough to support the weeping top."
