Another enormous flowering bush in the same back yard as the pink roses. This might be another rose, but I don't know enough about them to tell.
UPDATE: This appears to be a Yellow Lady Banks Rose (Rosa banksia lutea - see also http://www.helpmefind.com/rose/l.php?i=A514&tab=1)
There is another plant that I see a lot of in this area with yellow flowers and a similar "fountain" shape that is referred to as "Primrose Jasmine" (Jasminum mesnyi), but that has simpler flowers and different foliage.
Lady Banks in general and the yellow variety in particular seem to be getting more popular with landscapers in this area - I can see why as the only thing that appears to bother them is cold weather. I have recently noticed several bushes of Yellow Lady Banks along a fence in front of a local apartment complex. In the spring they are so covered with little fluffy yellow flowers that you can hardly see the plants. When they're finished blooming, they appear for the rest of the year as dense attractive shrubs.
