Carnivorous plants are addictive, in more ways than one, and a Geraldine grower has a vast collection to prove it. Words & photos: Rebecca Lees.
At 10 years of age, Ross Taylor was given a tiny sundew plant by a friend. He thought the plant was extraordinary, but it was after visiting a greenhouse full of North American pitcher plants that he became infatuated.
“They looked like something unearthly, and architectural, almost like a cathedral pipe bell. The plants are truly remarkable in their design. For a plant to be carnivorous it has to be able to not only attract, but also to catch and digest its prey. These plants are able to do all three of these things, simultaneously.”
Ross was so enamoured with the pitcher plants’ abilities, he had to have more. He sold his toys, his bike, and began picking tomatoes to raise money to buy more. A lifelong love of carnivorous plants was born and Ross now has the largest collection of North American pitcher plants in New Zealand.
“Many species of pitcher plants are critically endangered or extinct in the wild, and all of them are categorised as endangered species,” says Ross.
Carnivorous plants are incredibly interesting creatures. Take Sarracenia flava, the yellow pitcher plant, one of Ross’s favourites. Nectar on the hood of the plant contains an intoxicating substance. This substance has no effect on people, but it is very addictive to flies. The fly lands on the plant to eat the nectar, but ends up dining on narcotics. The insect may fly away, but they become so hooked on the substance that they most often come back to the plant for more, quite quickly.
Eventually, the fly migrates underneath the hood, onto the neck of the pitcher. It is in this position where there is a much more abundant supply of the intoxicating nectar. As they absorb the narcotic into their system, the fly becomes quite dopey. (“You can almost touch them with your finger,” says Ross.) The fly becomes so intoxicated that it ultimately falls down into the pitcher tube.
Once inside the tube, the fly can’t escape. The tube is covered in a waxy substance, which clogs up the fly’s feet. Flying out isn’t an option either, as flies require a runway to take off and this space is far too confined. Once the fly is in the tube, it’s there to stay. Eventually, the fly dies and is dissolved as the plant’s digestive enzymes reduce it to proteins and amino acids. This ‘soup’ is food for the plant and makes up for the nutrient-deficient substrate in which the plant is growing.
In some species, the hood of the pitcher plant is specifically designed to funnel rain away from the mouth of the plant. This ensures the plant liquids required for digesting flies don’t get diluted and that the trap doesn’t topple over because of the weight of the water in its tube.
Other species of pitcher plant work in very different ways to capture their prey. The tube of the Southern pitcher plant (Sarracenia purpurea ssp. venosa), for instance, works in the opposite way to most pitcher plants. In this species, its pitchers fill with water when it rains. Some insects have the ability to walk on water, so this plant creates enzymes that remove the meniscus from water so nothing will float on top of the water, allowing the plant to catch its prey through drowning. The plant also has downward-pointing hairs on the tube, which makes it more difficult for the fly to get a foothold and come back up the trap.
Ross eventually turned his love of plants from his childhood into a semi-commercial business based in Christchurch. In his heyday, he had raised over 100,000 plants in glasshouses. Ross was loving his work and doing well, and his plants were thriving – until disaster struck. On February 22, 2011 the Christchurch earthquake badly affected his infrastructure and many plants died as a result.
“Benches filled with plants collapsed. Broken glass was throughout the collection. Irrigation became impossible, and thousands of plants were upturned and a great many died. It was soul-destroying.”
Ross managed to keep his remaining plants alive for a few years, but it was a real struggle. He needed a fresh start. A property he liked came up for sale in Geraldine, South Canterbury. Ross closed his business down, packed up the best of his plants and moved south. There he returned to being a hobbyist once again.
Ross’s love of the plants remains, and his knowledge and reputation continues to grow. He has regular visitors to his property, many travelling from around the world to see his collection, and New Zealand residents are able to purchase a few to take away with them.
On entering Ross’s tunnel houses, I was amazed. The rooms are packed with a vast array of pitcher plants, their tubes ranging in size from over a metre down to smaller, dwarf-sized plants with a height of just a few centimetres. An array of colours – reds, purples, greens, browns and whites – fill the tunnel houses. The sight was like seeing thousands of hungry mouths, all wide open, waiting patiently to be fed.
With more than 15,000 plants growing, you would wonder how they all survive on insects alone. “All of these plants thrive here and I don’t feed them anything. There are plenty of flies to go around.”
Ross had several visitors while I was there, and all of them seemed awestruck by the sight. I couldn’t help purchasing a plant for myself, and I have been caring for it ever since. It’s doing well. At first my daughter and I caught flies to feed it, but we needn’t have bothered. Its main tube is already about three-quarters full of flies, with another tube growing. By the end of the season it should have between 5 and 10 tubes.
