Dear Lee and all, I think your correspondent might do better to Google the topic. There has been a lot written and plant selection varies by topic. I think there's a lot of non-bulbous plants that might be better choices especially for year round growth and activiity in your climate. The suggestion of iris pseudacorus is probably not a good idea de to its vigorous weediness. I know various water cannas have been used in this way, but your correspondent wants plants with year round activity. Maybe asking the local Ag Agent is the best bet to see what others in your specific climate might recommend. Good luck. Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
