Lupine is a perennial pea plant that grows about 1–1,5 meters high. Lupine's inflorescence is tufted and long, and can be blue, purple, pink or white in color. The color of the flower can vary even in the same individual. The leaves are long-stalked and its root system is strongly branched.
The plant sap of the giant tuber causes burn-like injuries on human skin when it reacts with sunlight.
You can recognize the giant pipe by its leaves, which are significantly larger than, for example, the domestic thunder pipe or bear pipe. The flower stem can grow up to 4-5 meters high and the inflorescence is white and 40-80 cm wide.
The seeds ripen in autumn and fall during autumn and winter.
Giant balsam is an annual succulent-stemmed grass with large light or dark red flowers. The plant grows approx. 1,5-3 meters high and makes a home from which the seeds are easily thrown into the surrounding environment. Giant balsam only regenerates from seeds, so it is important to uproot the plant before seeding. Extensive vegetation can also be mowed before flowering.
The kurturus is a perennial shrub that grows from half a meter to one and a half meters. It effectively forms root canals, which can be used to form even large stands.
The leaves of the withered rose are thick and wrinkled and the branches are densely spiky. The spikes are of variable length and straight. The rosettes of the plant are flattened in the middle. The flowers are large, pink or sometimes white.
The Spanish snail is usually a large species of brown snail that is found in almost all of Finland. If you have encountered Spanish sedge in the area, you should keep the lawn and yard vegetation short, airy and neat. Piles of leaves and twigs should not be stored in the yard.
Since the eggs and small individuals of the Spanish beetle spread easily with plant waste, soil and seedlings, their distribution and transfer to new areas must be avoided in order to prevent the spread of the Spanish beetle.
