We have this rose bush in our front yard that is just incredible.  Our house is probably more than 100 years old and I imagine this rose has been here since the beginning.  We have had scores of roses off this single bush and it just keeps producing.  It begins blooming in early spring with a soft pink and creamy white rose.  Now, in the fall, it is still covered in buds.  But as the temperatures change, the colors become more intense and this brilliant yellow is introduced.  And these roses smell so good, their fragrance is wonderful...that classic rose perfume.  Too bad I can't copy & paste it...maybe a scratch & sniff icon...?
