I haven't bought a vintage hyacinth vase all year so far on ebay. I did see this brand new one (from Ravenhead Naturals) and was curious what it would be like. I show it here in comparison with the most common shapes/sizes of vintage vases. The teal vase in the centre is about 19 cm tall and the new clear one on the left is about a cm shorter at about 18 cm tall. I don't have a hyacinth bulb handy to show it with one but it does appear to have a good opening size to grow a hyacinth in which I will be doing later this year and will report back at www.gardenwithindoors.org.uk.
