I used to own a house with a small walled in garden. Previous owners planted a tall bearded iris, pale lilac in color and unknown to me. When the sun hit blooming flowers in spring the garden became so beautifully fragrant it was like a drug. When I left that house I did not take any with me and will always regret it. I have looked for it ever since but have never found anything quite similar. Perhaps it was a combinatiion of plant scents or the fact that wind could not disperse the fragrance. Very heady. Certain lilies have the same drugging effect for me. Kathy Stokmanis Gardening in the foothills of the Sierra Nevada in California, where high winds and much rain are the order of the day. Very hot and dry in summer, very wet in winter, little or no frost.
