Factors such as rarity, beauty, breeding, and propagation all potentially play a role when it comes to pricing expensive plants. Gardening activities have become increasingly popular in recent decades with the younger generations, and there has been a “plant boom” of late. The desire to own rare and attractive species is also, consequently, rising. As an example, to meet recent demand, cuttings of variegated monstera plants are selling for three-figure prices in Australia, Canada, and the United States. The millennial generation is not the first to start such a movement. In the early 1600s, the “it” plant of the time was the tulip. “Tulip Mania” caused the price of tulips to explode, selling for up to 5,700 guilders. Following this trend, the next flower of a century became the orchid. Wealthy Victorians loved orchids so much that their obsession became known as “orchidelirum.” As we look closer at the boom of the 21st century, here are six of the most expensive houseplants. Fiddle leaf plants are especially sensitive to air quality. They do not like dry air or drafts, nor do they respond well to too or not enough sun, the list goes on. Purchasing a mature tree is a big commitment. While it may be easier for a professional to grow such a large fiddle leaf fig, owning one will be a challenge unless you are aware of how to care for it. Consider placing a humidifier in your home for this new addition. Beloved in New Zealand and other parts of the world, the Variegated Monstera is currently one of the most popular plants. The plant’s slow propagation rate, however, makes it very rare. This plant can be found with random splashes of color in many shades with no two leaves shaped the same. Its uniqueness has made it the darling of countless social media influencers in the plant community. Normal green varieties sell for just $20 at garden centers, while the prices of variegated varieties are climbing. If you decide you must have a Hoya, other varieties that are not quite so expensive. As New Zealand’s passion for houseplants gows, an extremely rare variegated specimen sold in August 2020 for $8,150 on the country’s largest trading site Trade Me. What makes this sale even more surprising is that the small minima had only four leaves. Sold modestly in a six-inch black plastic pot, the intrigue came about as a result of the description, which showcased the plant as “very rare” and “with stunning yellow variegation on every leaf.” Prices of P. lynamii and P. joepii are also increasing. While typical P. minima sell for $20 to $50, variegated varieties cost more. Houseplant enthusiasts seek variation in spots, streaks, and blocks. These stunning blooms, at least, dazzle the senses with a particular scent, but the plant is so rare that few will ever get to inhale its fragrance. Precious specimens are auctioned off for up to $200,000.
