Below are links to our Research Newsletters that are being published in cooperation with the Royal Dutch Wholesaler's Association for Flowerbulbs and Nursery Stock, in Hillegom, Holland. These are industry-oriented publications, full of pictures, that should be useful to a wide range of readers.

(May 2006) In this newsletter, we show how many of the hybrid lily cultivars originally breed for the greenhouse cut flower industry actually make fabulous garden plants in Zone 5. Also included is an article with preliminary results from Long Island experiments of Dr. Mark Bridgen on outdoor cut lily production.
