It has taken some years to have enough of an increase in these bulbs to become a patch of flowers. Then a couple of nights ago I happened to go past them after dark. It was a wind-still evening and the scent from the Z. drummondii was just amazing. And the white of the flowers almost glowed in the dark. It was the first time I had that experience since planting the seed in 2008. And the scent was still there the following morning. Now I see what is meant by them being night flowering. As the flowers are open during day and night for some days, it had not been so noticeable. -- Ina Crossley Auckland New Zealand Zone 10
