It's been a hot summer, we hope everyone's plants are still looking good. Things are going well here at the greenhouse. Fall mums are coming along nicely, and the rest of our fall annuals will be arriving later this month. We have been hard at work preparing for next season with new giftware and ceramic pottery beginning to roll in. If you are still looking to plant, all remaining perennials and shrubs are on sale. We will be here 7 days a week until the end of October.
