Sustainability within the floristry industry is starting to gain some real traction. From ditching harmful floral foam to sourcing local flowers to cut down on travel emissions, florists can make a big impact.

Bloom’s philosophies on sustainability within the floristry industry are clear:

We are passionate about sourcing local botanical materials and using sundry materials with a low environmental impact
We do not use floral foam unless it is absolutely necessary
Where possible, we support organisations and charities that assist the communities of developing nations
We purchase items from these communities, such as hand made products which ensure the profits go directly into helping the community

It is a little known fact within the general public that often flowers purchased and consumed in Australia are imported from overseas. These flowers come from as far away as Africa and South America. There can be many unethical issues with this practice, both environmentally and also from a humanitarian standpoint.

Some developing nations produce high volume, mass-produced botanicals. Often this comes at a cost to both the environment and the treatment of those employed at these workplaces. The lack of environmental protection laws and regulated work conditions in these countries lead to devastating consequences for some communities.

Environmental issues caused by some farms include devastation to local waterways and soils due to pollutant and chemical run-off from the flower farms. This can affect the sources of water used for drinking, bathing, cooking, and agriculture in the communities, affecting the community’s health and the biodiversity of the area.

In addition to the humanitarian perspective, the poor working conditions these flower farm workers experience can be horrendous. They can be forced to work long hours in unsafe conditions, for little pay, and are sometimes subjected to physical or sexual abuse. It’s so important to be aware of this issue and to consider where your flowers are coming from, how far they have travelled, and the potentially high price paid by others for these flowers to be sold at a low cost to the consumer. We also acknowledge this is not the case for all flower farms and there are some ethically conscious operators.

Australia, UK, USA, Canada, New Zealand and many other nations, have an emerging group of wonderful growers of beautiful botanicals. Especially those fortunate enough to have a continent that spans through many different climate zones. These different climates enable local growers to cultivate varieties that thrive in cold, temperate, dry or tropical climates.

We recommend that you start to make yourself familiar with your local growers, within your area, including their seasonal varieties and growing practices, so you can better understand the growing process. With more understanding, education, and awareness, sustainability and ethical issues can be recognised and better dealt with.

To understand sustainability more thoroughly, and how it relates to floristry, let’s look at how it is categorised. Sustainability is divided into three categories: environmental, social, and economic. Let’s have a look at the considerations to take into account with each.

Environmental

Transportation
Pesticides
Water usage – for the growing process, and storage and handling for the florist
Land usage – for the growing of botanicals, and effects on local biodiversity
Electricity usage – for running cool rooms, refrigerated transportation and where that electricity is generated

Social

Human rights and safe working conditions for workers in developing nations
Social responsibility of consumers
Liveability concerns for some communities that are reliant on this industry
Health equity for those involved in the growing of botanicals

Economic

Cost effective energy bills
Competitive but profitable supply chains
Re-use of non perishable products

This theory is effectively detailed by the following Venn diagram:

Sustainability is relevant to each of us, both in a local sense and also when looking at it from a global perspective. It is important to make educated choices for creating and maintaining sustainable practices within your workplace and as much as at home.

From a floristry perspective, you can do this by researching online products, growers, materials, botanicals, organisations, and charities that you can support and learn from.

We also teach sustainable practices extensively in our Bloom College Career Change Course. It’s so important to kickstart a career in floristry with the knowledge required to build and maintain a sustainable business. If you’re not sure if this course is the right one for you, get in touch! We’re more than happy to answer any questions so you feel 100% confident in your floristry path.

Floral foam has been a source of contention for the floristry industry of late.

These green, sponge-like foam blocks are an easy way to arrange flowers and keep them hydrated with very little mess. In more recent years it’s also become popular on social media ASMR videos because of the satisfying crunching sound it makes when you crush it.

Unfortunately the ease of floral foam comes at a high cost to the environment, with researchers finding that it is contributing to microplastic pollution in our oceans, and the toxic chemicals used to make it are harming the sea animals who consume it.

What is floral foam?

Just about any florist in the industry today will have used floral foam at some point in their career, if not every day.

Floral foam was invented by Smithers-Oasis in the 1950s in the U.S. and quickly became the material of choice for floral arrangements. It’s lightweight, easy to cut and mould, and is able to hold up to 50 times its own weight in water. Floral foam is relatively cheap too, making it all the more appealing to florists just getting started in their businesses.

Floral foam became the catalyst for more complicated floristry designs, opening up a new world of possibilities for floral designers. Suddenly, they could create hanging installations, arches, table centrepieces and other large designs with relative ease.

What is floral foam made of?

The unfortunate truth of floral foam is that it’s made of plastic.

Specifically, a type of plastic similar to house insulation foam known as phenol formaldehydes. These were the first plastics to be developed in the early 1900s.

To get into the science-y bit, floral foam is made using phenol, formaldehyde polymers, surfactants, and wetting agents. Both phenol and formaldehyde are considered to be hazardous chemicals as well as carcinogens, however, they are mixed with non-hazardous substances to form floral foam.

Is floral foam toxic?

Short answer, no. Long answer, kind of.

While floral foam can cause eye, skin and respiratory tract irritation, it is not considered toxic when handled under normal conditions. This is because the toxic chemicals found in your standard block of foam are present in very low concentrations.

However, while it may not be toxic to a florist who is handling it semi-regularly, a recent study found that the toxins are causing problems for the sea animals who are ingesting them as microplastics.

This study also showed that the toxic phenols were able to separate from the floral foam into the water, which means that sea animals are swimming around in water that contains toxins and microplastic floral foam particles.

What is floral foam’s effect on the environment?

This same study from RMIT University completed tests on invertebrates that consumed floral foam. What they found was that the species displayed signs of toxicity upon ingestion. The study also noted that, ‘Biofoam microplastics leached more than twice as much phenolic compounds than regular foam microplastics.’ This means the microplastics leaching out of floral foam are doing more damage to our sea life than any other foam microplastics.

While research has not yet been carried out on the effects of foam microplastics in larger sea species, it’s already a widely known fact that most sea life contains microplastics. A comparison study done by the University of Adelaide on microplastics in fish in Australia and Fiji found that, ‘In Australia, plastic was found in 61.6% of fish gastrointestinal tracts, while in Fiji, 35.3% of fish had plastic.’ If we’re already ingesting microplastics from the fish we eat, it’s not a stretch to assume we have already or will eventually be ingesting toxic phenols from floral foam in our seafood too.

Rita Feldmann, founder of the Sustainable Floristry Network is quoted as saying, “For an industry that seeks to celebrate nature, we are actually adding to environmental problems when using this product,” when talking about floral foam. It’s hoped that the scientific findings will discourage florists across the globe from turning to floral foam, opting instead for more sustainable methods of arranging.

But it’s not just florists who are flushing their fair share of foam down the drain––floral foam has recently gained popularity on social media in ASMR (Autonomous sensory meridian response) videos. The highly satisfying, crisp sound it makes as it’s crushed has people flocking to these videos for that ASMR scalp tingling sensation. And, to top it all off, some creators will even add glitter (another microplastic) to the foam, before washing it all down the sink.

Even if floral foam is disposed of in the bin, it goes to land-fill where it won’t break down and can’t be composted, just continuing to leak toxins into the environment.

What can I do about it?

The simplest way you can make a difference when it comes to floral foam is to stop using it.

While it can seem intimidating initially to forgo a material that’s been vital to your arrangements for as long as you’ve been in floristry, there are a lot of really good alternatives out there.

We actually put together a list of floral foam alternatives that you can check out here.

Another great way to help out in the sustainable floristry space is to educate yourself and start filling up your online space with like-minded, sustainable florists. Some great accounts to follow on Instagram are:

@nofloralfoam – focused on raising awareness about plastic floral foam and alternative floristry techniques
