by Brett Myers In order to gain some experience with the plant species on our list seedlings from germination studies were transplanted to a plot of unused ground next to the headhouse of the Howlett Hall Greenhouse. This gave us an idea of how species would perform when established in favorable conditions under intensive management. This site was prepared for planting from 6/12 - 6/19/96. An area 30 x 17 ft was sprayed with Round-up herbicide and then hand weeded. The site was then tilled with a rotary tiller to 6 in. depth and covered with approximately 1 inch of hardwood mulch. About 25 work hours were expended in site preparation.

Howlett Site Plan All plants were spaced approximately 12in. apart to create an immediate effect. Unless otherwise stated in the table plants were set out June 19 1996. The planting was arranged according to expected height with species becoming taller away from the sidewalk. Grasses were mixed with forbs for visual impact, weed control and to provide support for weaker stemmed species. There was no deliberate arrangement according to color, as it was expected that all would be compatible and we hoped to discover attractive combinations. After planting the site was hand-weeded and watered whenever the soil appeared dry. These might seem like luxury conditions for wild plant species, but our desire was to see how well they could establish under favorable conditions before planting in more challenging situations. Plant and site views were taken with an Apple digital camera throughout the growing season.
