I think that if you're not a gardener yourself, you might find them more convincing than someone who's a keen gardener would. But if you're looking for something that you personally think is pretty, then you don't need to worry about 'getting it right'.
I was at my parents' house today and they have some trees that are still flowering in October! so I was asking what they were. My Dad told me various names, but the one I liked, an orange one (can't remember) he said the spikes on it would injure the children if they fell against it. Another attracts wasps like a pot of jam. Maybe he gave me too many latin names. I'm addled. I am busier than my Dad as well, to be blunt.
I'd consider it - we're putting the house on the market soon, could do with some kerb appeal, and both have brown thumbs of doom. That said, my big gardening success has been with a bay, so maybe I should get a couple of real ones (the one I have is I the back garden and is about 12ft tall, so not an option!)
