Q.Name Of A Weed Type Tree
An evergreen tree that just pops up anywhere, has weak branches to begin with. The tree appears to flower twice a year, once in the spring with a fluffy white broom type array; similar, in the spring to that of a pyracantha. The second flower is in around mid to late summer, and is a sort of pink or red global flower about 30 or 40 millimetres in diameter, made up of short stems, similar in shape to that of stamens within the petals of a flower. Both of these times are a good floral display. I knew the name once and thought it did not sound like a weed nor does it look like one. It is easy to remove if it takes root in undesirable places.
