Pink pineapples have captured public curiosity with their striking pink flesh and sweeter taste. However, many people are surprised to learn that growing certain varieties—particularly the popular Pinkglow® pineapple—can cross into legal territory. While it’s not illegal to grow just any pink pineapple, the commercial version developed by Fresh Del Monte is strictly protected by patents and trademarks.
The Rise of Pink Pineapples
Pinkglow pineapples are a genetically modified variety engineered by Del Monte. The pink color comes from a deliberate genetic tweak that suppresses the natural conversion of lycopene (a red/pink pigment) into beta-carotene (the compound that gives regular pineapples their golden-yellow hue). As a result, these fruits develop a vibrant pink interior, higher lycopene content, and a sweeter, less acidic flavor profile.
Del Monte invested more than 15 years in developing this variety before its commercial launch around 2020. The company grows them primarily under controlled conditions in licensed farms in Costa Rica.
The Legal Reality: Patents and Intellectual Property
The core reason growing Pinkglow pineapples is restricted lies in intellectual property law. Del Monte holds multiple plant patents and utility patents covering the specific genetic modifications and the process of reproducing the variety asexually (such as from crowns or tops). These patents grant the company exclusive rights to propagate, sell, and commercially use the plant.
Under U.S. law and similar regulations in many other countries, unauthorized reproduction or commercial cultivation of patented plant material constitutes infringement—much like copying a patented invention. Del Monte learned from past experiences with their popular golden pineapple, which competitors quickly replicated after it entered the market. For Pinkglow, they built a stronger legal framework, including trademarks on the name “Pinkglow®” and tight controls on production locations.
Reports exist of authorities destroying unauthorized plantations in regions like Costa Rica and neighboring countries, and Del Monte has pursued legal action against violators.
Why Del Monte Removes the Crowns
To prevent home gardeners and unauthorized growers from easily propagating the plants, Del Monte typically removes the leafy crowns (tops) from Pinkglow pineapples sold in stores. Regular pineapples are famously easy to grow from their crowns, but this step effectively limits casual reproduction of the patented variety.
Is It Illegal for Home Growers?
For individuals, the situation is somewhat nuanced:
- Personal, non-commercial use: Growing a single plant from seeds or a crown for home consumption exists in a gray area. Patent laws primarily target commercial activities such as selling plants, fruit, or propagating for profit. However, technically using the patented genetics without authorization can still infringe intellectual property rights.
- Commercial growing or selling: This is clearly prohibited and can lead to lawsuits or enforcement actions.
It’s important to note that not all pink pineapples are restricted. Rare natural variations or other non-patented types face no such limitations. The restrictions apply specifically to Del Monte’s proprietary GMO variety.
Broader Implications
This case highlights ongoing debates in agriculture about corporate control of seeds and plants, the role of GMOs, and the balance between protecting research investments and public access. Del Monte maintains that strong patent protection is necessary to recoup the significant costs of development. Critics argue it limits access to innovative crops.
The Pinkglow pineapple is FDA-approved as safe and is sold at a premium price in select markets, mainly in the United States.
In summary, growing pink pineapples isn’t banned because they are dangerous or forbidden fruit. The “illegality” stems from standard intellectual property enforcement designed to safeguard a branded, patented product. As with many modern agricultural innovations, the pink pineapple represents both scientific achievement and the complex legal landscape that surrounds it.
