Gardeners' Notes:

Positive TBGDN On Apr 13, 2006, TBGDN from Macy, IN wrote:

This is probably the largest flowered narcissus I grow. The orange color intensifies after a day or two. Like many other narcissus, the true or advertised color sometimes takes several days to develop; i.e. Salome, Romance, Mount Hood, etc. It is usually very windy here during bloom season, and they are likely to bend with the wind.

The only thing I don't like about this daf is that it has a hard time keeping it's head up. But the flower is huge, and it's a beautiful daf.
