I think Christine you are stretching the point about the neck. With the page open, and my vase tilted to the same perspective angle - the neck on mine disappears also. However, you don't have mine with which to do that, so perhaps you have confused yourself. The one in the book is getting on for 4" tall, so I think it is not out of the question that it might support the root mass of a hyacinth. Do you have personal experience of growing bulb varieties in smaller bulb vases?? - If you do, then share your results with us, and tell us the mean or average length of hyacinth roots when grown in smaller restrictive vases. As a suggestion, how about 'bonsai' hyacinths. I wud, however, concede that the top curved part of mine appears shorter - also that my base is less rounded. My original point really tho, was just that the overall shape seemed so similar. My thanks, however, for your critical assessment, what is the point of not being pertinent. Maybe I will try and grown a bulb in mine. cheers Paul S.
