Western science regards plants as passive creatures, because their movement is not immediately perceptible to our animal brains. This is far from the truth. Let's take a look at plant activity/movement and how it relates to intelligence:
Plants respond as individuals to all kinds of signals. One of the most common signals is sunlight. The response of plants to sunlight is known as heliotropism. This concept was known to ancient Greeks.
Heliotropic flowers (such as daisies, Bellis perennis) close their petals at night and open in the morning light to follow the sun as the day progresses. Sunflowers are perhaps the most obvious example. They collectively turn east at night in anticipation of dawn
The stilt palm is a plant that "walks". It has a stem raised on prop roots and moves toward sunlight by growing new prop roots on the sunny side while letting those in the shade die off. Over several months, it actually changes places.
Cuscuta, or dodder, is one of the plants that moves most perceptible to humans. It wraps itself around other plants and can estimate their nutritional quality within 60 minutes. It grows more coils based on how nutritious a host plant will be. Check it out
Plants are also touch-sensitive. One gentle stroke can be enough to fire off calcium levels inside the plant's cells instantaneously. This is not unlike human neurons using calcium elevation to relay information.
Besides sunlight and touch, plants react and move in response to their ecosystem. Lotus flowers can regulate their own temperature like warm-blooded animals. They maintain a temperature of around 86 degrees, even when the air is as cold as 50 degrees.
Lotus flowers lure in pollinators like bees and beetles. Like a little hotel, they can keep pollinators warm during a cold night, which allows them to stay active and be fully coated in pollen by morning.
Plants also react to sound. Using their flowers, they can hear animals (such as the buzzing of bees) and react by sweetening their nectar. They also emit high-pitched noises, which may be a form of communication.

Much of our inability to perceive intelligence in plants is due to our animal nature. We experience time at a fixed rate, causing us to miss a universe of activity that is happening right in front of us. By adjusting our perspective, we discover an entirely new world.
