There are an estimated 400,000 species of plants on earth. While this includes species such as giant marine kelp, leafless parasitic plants, and a slough of other ones not ultimately suitable for indoor cultivation, there are a significant number which will do quite well in an interior setting provided a few basic conditions are met, and certainly more species than are typically seen indoors.

It seems then a disservice to our clients, our own industry and plants in general that most companies seem to prefer to play it safe with the tried-and-true varieties that we’ve all become so accustomed to seeing. They’re about as common as dirt, as the saying goes, and, besides the fact that they (hopefully) have been grown as premium interior specimens and not hastened out the greenhouse door in the fashion of so many of the houseplants sold to the consumer market (the subject of another forthcoming post, I’m sure), there’s not really much to differentiate them from the plants that people are growing on their own at home, or at least that they’re so used to seeing everywhere that they don’t even notice them anymore.

It’s a disservice to clients because, while presumably done with good intentions in order to spare clients the sight of an ailing plant should anything go awry (most of these are very tough to kill [or at least they die slowly and relatively gracefully], and perform fairly predictably), it doesn’t really deliver a tremendous amount of value to the client: certainly they will get the physical benefits of having plants indoors (these benefits were touched on in this post), but the aesthetic and biophilic benefits of plants seem to me somewhat dependent on the plants being engaging and actually noticed, instead of looking like furniture as they so often do. And why have something commonplace when something extraordinary is just as much cost (on their part) and effort (on our part)?

It’s a disservice to our industry for several reasons. As I noted above, to the untrained eye these species, even if they’ve been better grown, look nearly indistinguishable from the ones that can be bought for a pittance at a big box store or wherever; it is challenging to justify the price point for them when someone thinks that they’re the same as the ones they saw for a quarter of the price up the road, even if they get the whole spiel about quality, etc. The other side to this is that many people grow these plants in their home themselves; why, then, would they pay us to do it? Yes, we can do a much better job (hopefully!), but it’s just another aspect we need to justify to the customer. Granted, there are some situations (extreme low light, for example) where only the bulletproof plants will do, but in most situations there is likely something more unique that could be used.

Lastly, it’s a disservice to plants (not that they care): what better way to share a passion for all things green than to try and show the public as much of that world as we can? There’s just so much out there that it seems strange to restrict ourselves to the commonplace when we’re in the business of bringing life into our clients’ spaces; certainly showcasing the extraordinary biodiversity that the plant kingdom has to offer is an effective way of doing just this.

Plants are able to do so much for us, and technology now makes it easier to keep species with particular requirements happy without any additional work (the Calathea above would certainly be trickier without the sub-irrigated planters it’s in; it’s relatively easy to grow so long as it doesn’t go dry). Vertical gardens allow the perfect growing environment for plants so uncommon in cultivation that they don’t even have a common name; the combination of ample water and high humidity makes a huge variety of plants available to the vertical gardener. What a shame then to see so many large, high-profile projects populated by pothos and other common plants when the whole of the tropics could have been the designer’s oyster.

In Situ challenges all in our industry (growers, local wholesalers and interior landscaping firms) to venture off the well-trodden path of Dracaena and Schefflera and step into a world rich in plant species which can grow our industry and the public’s love and appreciation for plants indoors.

If you’re unfamiliar with the chemical reaction above, then you may also be unfamiliar with the fact that life as we typically tend to think of it would not be possible without plants.

Photosynthesis is responsible for the capture of solar energy that in turn powers nearly all life on earth: everything we eat is either plants, or other animals that formerly ate plants (or that ate other animals that ate plants). Plants absorb sunlight and convert it into chemical energy which is stored within the plant for its own uses; we eagerly exploit this by consuming them and thus the sum of the solar energy they’ve stored. Good deal for us, bad deal for the plants (not that they seem to care).

There are not many other ways to capture and metabolize energy in this way, save chemosynthesis (which is why I need to keep referring to ‘almost all life’ above, which, while definitely less dramatic, is more accurate, as there are organisms which are able to capture energy from chemical reactions, most notably in deep-sea communities colonizing hydrothermal vents, and so have no need of sunlight). So plants really are the foundation of nearly all life on the earth.

And not just regarding energy, either. Though a bit more oft-toted, the fact that plants maintain the planet’s oxygen levels is equally prevalent. This does bring up the subject of conservation, but I can save that for another time. I will add in a shameless plug, though, that plants indoors will raise local oxygen levels and just generally improve the air quality indoors. You can read this post for more information if you like: Plants at Work: The Science Behind how Plants Improve Life Indoors.

For anyone interested in the equation who doesn’t understand the chemistry, basically the plant takes 6 molecules of carbon dioxide and 6 of water, and splits these to create free oxygen (which is released by the plant), and a few other goodies which combine with the solar energy captured by the chlorophyll in the plant to create carbohydrates (the C6H1206 in the equation above) which contain that solar energy. Pretty simple, but critical to life on earth.

It’s a little humorous to me that our industry (speaking very broadly here, of course) provides, in a manner of speaking, a product that no one can live without. Maybe that’s why everyone tends to like plants so much: I’ve met many people indifferent to them (and have changed a few minds there), and many more people who love them but can’t seem to stop killing them (and I can only hope I’ve helped a bit there), but have never really met anyone who’s said that they actively dislike plants (except maybe recent victims of poison ivy or the like). Maybe it’s a stretch to assume that we as a species are that aware of the inexorable connection we have with the rest of life, but for whatever reason the biophilic instinct is certainly alive and well.

Just a short one here, but I’m pleased to report that the little gametophytes I wrote about back in June have started to produce their first fronds, AKA sporophytes (being the part of the plant that eventually produces the spore which gifted us with the gametophytes in the first place). Again, I can only presume that these are Adiantum peruvianum, as this is the only fern species in this garden, but there are a lot of other ferns here at the lab (to say nothing of the effectiveness of travel by spore; these ferns really could be from anywhere), and so I’m still not 100%. (And there’s actually a terrarium in another room of the building that appears to be growing something similar, so the plot could still thicken here.)

They’re pretty cute, though, either way. As soon as we start to see more mature foliage on these plants I’ll update again with a more conclusive ID. The plants pictured here are way up at the top of the wall, and should produce a nice (albeit unplanned) cascading effect once they get going (again, presuming they’re even A. peruvianum).
