Flowers by Leslie - Our Story

Providing the Portsmouth community with the finest and freshest flowers and plants since 1966, Flowers by Leslie continues to offer stunning and stylish floral arrangements with reliable delivery and outstanding customer service

Portsmouth's Finest Florist

Flowers by Leslie is the premier florist for the Portsmouth, NH, community and beyond. Providing excellent customer service is our driving goal, and we accomplish this by working with only the freshest and highest quality flowers and plants and providing reliable delivery of gorgeous arrangements that exceed our customers' expectations. We also offer same-day delivery for your convenience and a wide selection of flower bouquets and gifts for any occasion.

In business since 1966, we are proud to have served the Portsmouth area for so long. In 2019, Jayne Densmore purchased the shop with the same passion, values, and dedication that built Flowers by Leslie. Since then, we have expanded our retail location in Portsmouth to accommodate design classes, private events, upscale weddings, and a more extensive selection of gifts, including custom gift baskets and wine. We also established a second location 25 miles away in Rochester, NH, further expanding Flowers by Leslie and our delivery capabilities.

We have always made it a point to get involved in our community and engage with our customers on a more personal level by donating our time and resources to local charities, schools, and various other community programs. Being involved and caring about our community allows us to better serve our customers by creating floral designs that perfectly match the expression or emotion they want to convey but are unable to do so with words. This is why flowers are so special; the variety of blooms, colors, shapes, and fragrances all play a part when arranged in a certain way to help express a wide range of feelings. From joy to sorrow to love and gratitude, we are experts in the language of flowers.

Additionally, joining a local buyers group has allowed us to connect with farmers and order all of our flowers directly from those whom we have met in person. This means we have the highest quality flowers and new and exciting varieties, creating a fresh and unbeatable selection for our customers. Thanks to the local organization, Jayne has found a new passion for sourcing, building relationships, and learning more about farm flowers and plants.

Driven by four master designers, arrangements from Flowers by Leslie have a whimsical and fresh style. However, we can do anything from unique, upscale garden-style arrangements to modern or traditional styles and even custom designs explicitly tailored to a customer's taste. Having exceptional design skills, an intuitive sense of what someone is trying to express, and going above and beyond in customer service sets Flowers by Leslie apart from other florists.

While floral arrangements are our forte, Flowers by Leslie has a large retail space and gift shop offering a wide selection of green and blooming plants, succulents, and one-of-a-kind local goods such as candles, chocolates, gift baskets, and wine. Whether looking for that perfect gift or a lovely sentiment to enhance your flower bouquet, Flowers by Leslie has it all.
