I am much along the lines of Dahlia's story. DH has one name for almost all the plants & it isn't even a real name. He does know many of the real names but doesn't use them unless I press him on the subject. He helps as Dahlia's beau does & suggests trips to the nursery where he patiently (& sometimes NOT so patiently) waits or helps carry plants to the car.
Funny thing though. My DH has DEFINATE ideas of what he likes & doesn't like, even down to his preferred colors of blooms on this or that.
But overall my gardening time is my own alone, down time from the outside world. That is where I gather my thoughts, solve problems, or think of nothing at all or just enjoy the beauty surrounding me.
