This week the big greenhouse attached to my house (two stories high, 15 m long) has been filled with a musky perfume each night. I have only a few plants flowering - some cyclamen and Salvia gesneriflora - so I was puzzled. Then I found a pot of Muscari with small green flowers. Could that be it? It is not scented at all in the day, and at night it isn't scented either when I sniff it directly. Very odd. Diane Whitehead
