As Valentine’s Day approaches, purchases of flowers increase. Whether for a holiday gift, special occasion, or other celebration, most of us will buy bouquets or flower arrangements at some point. But have you considered sustainable options or the best way to manage bouquets after they fade?

Why it matters

When you think about the economic impacts of agriculture, you’re likely to consider crops used to feed humans or other animals. But floriculture is also “big business.” The USDA defines floriculture as “that branch of horticulture dealing with the production of field-grown or greenhouse-grown plants for their flowers or showy leaves.” According to the US Department of Agriculture National Agricultural Statistics Service (USDA NASS), in 2023 (the year with the most recently published data), floriculture sales in IL totaled $134,063,000. For the same year, the Society of American Florists, reports total spending nationwide on floral products (flowers, seeds, and potted plants) was $72.8 billion.

While the USDA NASS estimates there are approximately 263 commercial floriculture operations, throughout IL alone, most of the flowers purchased in the US are imported from other countries. Utah State University Extension notes that “As many as 80% of all cut flowers sold in the U.S. are imported, with the majority coming from Columbia, Ecuador, Holland, and African countries such as Kenya that have the climate for the year-round cut flower cultivation (Cain, 2022; Knoch, 2022; Li et al., 2016; Tegethoff, 2023).” (See Utah State University Extension site for full citations.)

Clearly, buying and selling flowers has a huge impact on carbon emissions just from the perspective of product distribution. Imported blooms are flown thousands of miles and once they reach US soil, they might still end up being trucked for many more miles before reaching a retail location. Beyond the fuel used for transportation, refrigeration is often required along the way to keep blooms fresh.

Like any other agricultural operation, floriculture involves the use of a lot of resources (e.g. land, water, labor, etc.) and the application of a variety of chemicals that may have negative impacts on human and environmental health. A recent review of pesticides in flower production identified 201 different compounds used, 93 of which are banned by the European Union (Pereira et al., 2021).

So, although we tend to focus on aesthetics when picking the flowers we buy, attending to any available information on the source and production practices matters greatly if we care about environmental sustainability. It’s also worth considering the impacts of any packaging involved, which might be destined for the landfill if it can’t be reused, recycled, or composted. Because of the resource use embodied in them, it pays to consider keeping ornamental flowers and plants vibrant and in use for as long as possible, and when they are genuinely wilted and no longer lovely, we should try to keep them out of landfills if possible through composting. When plant material and wasted food (collectively called “organics”) break down in landfills without oxygen present (i.e., in anaerobic conditions), methane, a greenhouse gas is produced. The US EPA reports that municipal solid waste landfills are the third largest source of human-related methane emissions in the US, accounting for approximately 14% of methane emissions in 2022.

Better options

So how can you reduce the negative impacts of the flowers you buy?

Buy locally grown flowers whenever possible. If purchasing at a florist, grocery store, or large retail outlet, look for posted information on the source of the product or ask staff for more information. Depending on your location, time of year, and the intended use for your flowers, you may be able to get what you need from a farmer’s market or directly from a farm. This gives you the opportunity to meet the grower and ask questions about their operation. Buying local also supports the local economy and populations of pollinators, depending on the amount of shelter used in production (i.e. open fields, greenhouses, etc.). And of course, you’ll greatly reduce the greenhouse gas emissions involved in distribution. According to the Association of Specialty Cut Flower Growers (ASCFG), local flowers also tend to be of a wider variety, will last longer because they’ve traveled a shorter distance to you, and may smell better, because they are less likely to have been bred for uniformity, a practice that may compromise natural fragrance. If you don’t already have a farmer’s market or other favorite source for local flowers, the following resources will help you find them:

• ASCFG Find Local Flowers and Growers Map: https://localflowers.org/find-flowers/. Enter your location and choose a radius in miles for your search.
• IL Specialty Growers Association Live Local Shop Local Map: https://www.specialtygrowers.org/shoplocal.html. There are a few different ways to search. Either select “Floriculture” from the “Products” drop-down menu OR “Cut Flowers” from the “Product Attribute” drop-down menu OR type “flowers” or “cut flowers” into the search bar.

If you can’t find locally grown, look for sustainably grown options. This might mean using an online service that sources sustainably grown flowers or looking for certified products in shops. Links related to certification programs below will allow you to dive into the details of the program standards if you wish.

• ReVased: https://www.revased.com/. This company began in 2019 with a focus on “upcycling” flowers from events (more on that below), selling a portion and donating a portion of these reclaimed arrangements. When the COVID-19 pandemic caused events to temporarily be put on hold, they shifted gears and now primarily offer online orders of sustainably grown flowers and plants. From their website: ‘We are proud to source our flowers from high-quality, sustainable-minded farms in both the U.S. and South America. The flower farms we work with have achieved Rainforest Alliance Certification, Fairtrade Certification, or take other steps for environmental, economic, and social sustainability. This includes protecting forests and natural wildlife habitats; promoting farmers’ human rights and safe, decent working conditions; conserving water and soil; and helping to lessen the burden of the climate crisis. We are lucky to work with amazing farm partners who meet these rigorous standards of excellence! We also ship “farm-direct.” This eco-friendly shipping method reduces carbon emissions by bypassing many stops in the traditional floral supply chain and reducing the total number of stems being cut, as every cut stem is meant for a customer! Additionally, we offset emissions from our shipments to neutralize our shipping footprint and make our shipments carbon neutral.’
• Rainforest Alliance Certification: https://www.rainforest-alliance.org/insights/rainforest-alliance-certified-ferns-flowers/. The Rainforest Alliance certifies products that comply with their agricultural standard which “protects ecosystems and wildlife habitats, conserves water and soil, promotes decent and safe working conditions, and ensures that farms are good neighbors to rural communities and wildlands.” According to the Alliance’s website, Costco stores in IL sell their certified flowers, plants, coffee, and tea.
• Fair Trade Certification: https://www.fairtradecertified.org/what-we-do/what-we-certify/floral/. Fair Trade certified products comply with standards to safeguard working environments and conditions, living wages and benefits, and to eliminate poverty and forced labor. Check the packaging on products or signage at your florist or other retailer for an emblem from Fair Trade USA or Fair Trade International. According to the Fair Trade USA website, you can find certified flowers at Sam’s Club and Whole Foods.
• Veriflora Sustainably Grown: https://www.scsglobalservices.com/services/veriflora-certified-sustainably-grown. “This third-party certification assures buyers and consumers that cut flowers and potted plants have been produced in an environmentally and socially responsible way, with practices that achieve the highest level of product quality.” This is part of the SCS Global Services suite of third-party certifications, so look for an emblem with the SCS green hummingbird logo and the words “Sustainably Grown Certified.” Veriflora products are available through various florists and supermarkets, so check with your local shops.
• Organic:  While it is possible to find flowers with USDA Organic certification, this tends to be used for edible flowers or those used for tea. Many growers will follow organic principles without going through the formal certification process, which is why buying local is great if feasible, because it allows you ask questions and learn more about the production process.
• The Bouqs Co.: https://bouqs.com/about-us/our-difference. This online retailer sources directly from farms that use sustainable practices.

Reuse and other diversion options

If you’ve bought flowers for an event, when your festivities are done, there’s no reason to send those blooms to the landfill. Explore donation of arrangements that still look lovely, and composting when those flowers have truly faded.

• ReVased: https://www.revased.com/pages/non-profit-floral-directory. As noted above, this company started out by rescuing flowers from events to rehome them. Since the pandemic their focus is more on online sales, but they have started directory of non-profit organization that can accept donated flowers. Currently, all the IL entries are in the greater Chicago area/northern IL. You can also reach out to them at hi@revased.com for assistance in finding organizations to accept floral donation, but bear in mind their capacity for this is currently limited.
• Repeat Roses: https://repeatroses.com/. This company works nationwide and will be hands-on, collecting flowers after an event and delivering them to organizations to which they’re being donated. Where commercial composting facilities exist, they can also pick up donated flowers once they’re truly withered and deliver them to the composting facility. According to their website, “Some locations will offer only limited composting sites within reasonable driving distances. For those locations, we will explore alternatives to ensure we divert flowers from landfills.” In order to have this level of service, you’ll need to plan far in advance. “Four to six months is ideal to secure your date to ensure you are on our pickup schedule. The earlier you decide to reserve your date on the calendar, the more time we have to coordinate with your florist and venue. Often, it is easier for your florist to know of your plans to donate your flowers in advance so they can design your arrangements with this information in mind as it relates to vase/container rentals and arrangement structure. Additional fees may apply to events booked with limited notice.”
• Reach out directly to local organizations that may accept donated flowers. If you are planning an event that includes flowers, reach out in advance to local women’s shelters, nursing homes, hospitals, senior services, or cancer support non-profits to see if they could reuse your blooms and work with them, friends, or family on transportation of donations.
• Compost. Check the Illinois Food Scrap and Composting Coalition (IFSCC) website list of commercial compost haulers and processors or for tips on composting at home if you’ve got the space and the interest and you’re dealing with a bouquet or two rather than lots of flowers from an event.
• Preserve your blooms. If your flowers have sentimental value, consider preserving them. Check out HGTV’s guidance on various methods for drying, pressing, or using resin to create keepsakes.
