As with all other plants, growth occurs when there is sufficient moisture and the temperature is high enough above freezing. In the temperate regions of the northern hemisphere, this is usually sometime between spring and fall. Depending on the region and climate, yearly growth usually ends around mid to late summer when temperatures become too high and soil moisture becomes scarce (Higher temperatures increase the rate at which photosynthesis and other processes occur, which increases the tree's water requirements).
Hard wood.
Most sycamores are hard wood trees.
soft
Hard wood

At Soft Tree and Hard wood
it is a softwood tree
All conifer wood is classed as softwood.
One obvious difference is that Hardwood has leaves and soft wood has needles. Hard wood will lose its leaves. and hard woods is actually softer than soft wood! and the same with soft wood... pretty cool huh?
A seed is not a hard wood or soft wood. The seed might be of a hardwood or soft wood tree. I think many (not all) eucalypts (gums) are hard wood trees.
Maple is a hard wood (from a leafed tree) and pine is a soft wood (from a conifer). In this case both wood also have the described character (hard vs soft) not always the case.
Well hard wood is straight and soft is limpyBasically hardwood comes from a deciduous tree like the oak or ash. Softwood comes from conifers.
