That's an unusual urge..I know people often want and to bring stuff to their therapists, but this is the first time I hear someone wanting to bring flowers.

I am not going to measure this on the scale, as the measurement criteria doesn't makes sense to me. All I can say is that it is NOT inappropriate. Flowers or other symbolic gifts aren't something that could compromise the professional nature of the relationship with the therapist. So, if you want to do it you certainly may. Just keep in mind, as others have mentioned, that there is a possibility that your therapist may not accept them depending on how he defines professional boundaries. I personally would accept flowers from a client without hesitation because, as I said, this is not the kind of a gift that could "corrupt" a therapist, but I'd, probably, want to know what was behind the urge to bring them. I wouldn't be curious about it if it was a card, homemade cookies or a handmade item. But flowers have a bit of a different flavor symbolically So, may be your therapist would want to explore it as well..Just some thoughts..
