That looks like an amaryllis, possibly A. 'Green Magic' - currently stocked by Sarah Raven.
Thought so, definitely an amaryllis and very similar indeed to 'Green Magic'.
Isn't it a beauty I've just been browsing her website - her amaryllis bulbs are expensive but there are some real treasures.
Have you seen the price of her gardening pinnies in the Autumn catalogue? Sixty quid for a denim pinny Glad I've got a sewing machine
aym..........that particular amaryllis has been around for quite a long time. I bought a bulb from T and M in 1995 or 96 and it was sold as Papillon. Once the bulbs multiply and all flower together, it makes a stunning show. I've lost several over the years but the small ones I have presently are from the original bulb.
At that time, they were selling them with the advice to keep them "green" all year round - seemed to work well enough
