Tucked behind the sprawling grounds of Shades of Green, a 10-acre garden center in Celina, sits a house where Rebecca Calvert and Julie Holland often work into the wee hours creating floral arrangements for their Greenologie Flower Shop. Open since June 2025, Greenologie is a boutique floral design studio that offers handcrafted floral arrangements, flower delivery or pick-up, floral design workshops, and wedding and event floral design services.
