Gardeners' Notes:

oh my goodness, grow this lily IMMEDIATELY if you haven't tried it!! It's five feet tall, with stems thicker than my thumb, and magnificently fragrant. Furthermore, the lily beetles pretty much leave it alone. This is the one of the few lilies that looks as good in my garden as it does in the catalogs. To die for.

This is the third year I have had this lily my daughters mothers day gift to me. It is about the same height as my stargazers but it's fragrance is even stronger. There is nothing I don't love about this plant.

My experience with this lily is that it is quite tall, I have 4 plants and the tallest is over 6' and the shortest is about 4'. These plants are 3 years old. The flowers are so perfect they almost look artificial, and the fragrance is heavenly. Very strong stems with many flowers, a real show-stopper in my garden.

OMG, this is a STUNNING Lily. Huge blooms, mine was a full 9 inches across. The petals are thick and sturdy. Lovely fragrance, not overwhelming, but still noticeable. The plant itself is short, maybe.... 24 inches.

It blew away my Florist with it's size and beauty.

I cannot speak to it's hardiness, as it is new to our garden, but if I lose it over the winter, I would buy it again in a heartbeat.
