| In the 1890s Odone and Louisa Rosazza moved from Baltimore, MD to Avondale, PA. Odone was an expert stone cutter and came to work in the local marble quarries. Since the marble did not cut true when it was frozen, Odone did not cut stone in the winter months. To fill his spare time he took to a popular local business of growing mushrooms.
In 1912, Avondale Borough passed an ordinance no longer allowing mushrooms to be grown in the borough. In response, Louisa and Odone tore their mushroom houses down and built a greenhouse. In the late 1800s, and early 1900s all greenhouses in Southern Chester County, were built to grow either sweet peas or tomatoes. The Rosazza's greenhouse was no exception. Louisa would take the trolley from Avondale to Wilmington, DE to sell her sweet peas at the King Street Market.
With Louisa's good business sense and their son Clarence now working in the business, three more greenhouses were built in the 1920s. Carnations and Chrysanthemums were added to the flower line-up.
In the 1950s, Clarence and Fay, looking to expand the business to include their sons, bought a piece of property near Avondale, which included an apple orchard. Tom and Dick went to work at Glen Willow Orchard, and Ralph and Clarence continued to run the greenhouses. One more house was added. This one was a new style, covered with plastic instead of glass. With this new house came new crops, including potted plants like poinsettias, Easter bulbs and spring bedding plants.
In the 1980s, when Ralph and Barbara's son Danny joined the business, the final greenhouse was added. Because of growing demand, Barbara began making fresh floral arrangements. She was trained and certified by Longwood Gardens in floral design. Her outstanding designs brighten the spirits and decor for holidays and other special occasions.
Today there are over 15 different kinds of cut flowers grown in a variety of colors right here in Avondale. A large line of seasonal plants are grown to give color through out the year. Easter bulbs are grown by the thousands. Geraniums and other spring bedding flowers and vegetable plants fill bed after bed in the greenhouses. Garden mums cover a half acre in the fall. Bright red poinsettias fill an entire house during the Advent season.
Now in its fourth generation, Rosazza's Greenhouses is looking forward to a strong future.
