In the effort to ensure that your gardening summer is as carefree as possible, we have cured a list of decorative plants that really are not worth it. If you do not want to worry about the toxicity of plants, garden goons or demanding divas, then you will definitely want to stay away from these lovely, but time-consuming, cultivars:
Beautiful and deadly
Since plants do not have claws or teeth to protect themselves from predators, many have evolved with toxic compounds to defend themselves against insects, animals and humans. Although mortality from plants is extremely rare, you may want to keep these poisonous species away from children and pets. There are too many potentially harmful plants to list here, so see this page For a more complete accounting.
1. The narcissus of the poet. (Poetic Narcissus)
As part of the daffodil family, the poet's narcissus offers a magnificent display of pure white petals surrounded by a funnel-shaped yellow center bordered by a delicate red crest.
Named after the Greek hero Daffodil, whose love for its own beauty caused its disappearance, all parts of the narcissus of the poet are toxic, especially the bulbs that can easily be mistaken for onions. By containing lycorine, eating this plant can cause vomiting, stomach cramps and, in extreme cases, seizures and cardiac arrhythmias. It is also very fragrant and keeping a large amount of the poet's daffodils in a closed space is powerful enough to cause headaches and nausea.
2. Autumn Crocus (Colchicum autumnale)
A plant with autumn flowers, the autumn crocus offers showy flowers in shades of pink, purple, white and blue. But beware, these beautiful autumn flowers contain alkaloid colchicines. Although this chemical has been used for medicinal purposes to treat gout, atrial fibrillation and pericarditis, the plant is toxic if swallowed, inhaled or absorbed through the eyes. With symptoms similar to arsenic poisoning, acute exposure is usually felt between two and 24 hours and includes fever, vomiting, diarrhea, abdominal pain and, possibly, organ failure from various systems when left untreated.
3. Foxglove (Digitalis purpurea)
With tall spikes with a multitude of bell-shaped purple-pink flowers, each bloom of the foxglove plant has an intriguing patch of black and white spots on its inner cup. While it is a fascinating visual piece for the garden, all parts of this plant contain cardiac glycosides, a digitoxin that affects the heart. If swallowed, it causes low pulse rate, nausea, vomiting and heart contractions that eventually lead to cardiac arrest.
4. Lily of the valley (Convallaria majalis)
Sweetly scented, the lily of the valley has leafy buds with a delicate cluster of white flowers that look down. This small and delicate number is not only extremely toxic, but could also be classified as an aggressive producer. To date, 38 different cardiac glycosides have been identified in lily of the valley and consuming even small amounts can cause abdominal pain, decreased heart rate, skin rashes and blurred vision. Lily of the valley also produces small red berries, which are also poisonous, and could be especially tempting for children.
These plants are the real garden thugs, who quickly dominate and displace their most timid botanists. If you decide to plant this type of flower regardless of its aggressive nature, be prepared to cut and throw frequently enough to keep it under control.
5. English ivy (Hedera helix)
Considered an invasive species in many parts of the United States, English ivy has even been direct banned in the state of Oregon. While their vines adhere to excellent ground cover or a green building facade, their use elsewhere in the backyard can be problematic at the very least. Very difficult to control once it is established, it spreads so thickly that it can drown other plants and create an "ivy desert" effect, while its penchant for climbing can cause the young trees to fall off their weight.
6. mint (Mentha spp.)
Despite its culinary uses and its aroma of soft drinks, many varieties of mint, such as mint, mint and peppermint, are prolific producers. Using their double propagation technique, peppermint plants can conquer far and wide through underground rhizomes and horizontal corridors. They can quickly take new land, so it is best to grow them in containers and harvest their leaves frequently to keep them at bay.
7. Bamboo (Bambusoideae)
An exotic addition to the landscape of the backyard, bamboo is one of the fastest growing woods in the world. Producing more oxygen than the average tree, it can also be harvested and cured for its own supply of strong and durable construction materials. However, the main caveat of bamboo is its vigor to colonize new lands: it can (and will extend) beyond the line of its property and its neighbor's yard. Restless about commercial herbicides, bamboo can be very difficult to eliminate and it can take years to get it under control. Despite all this, bamboo can be successfully contained – here how.
8. Jenny crawling (Lysimachia nummularia)
With a common name like 'jenny creeping', it would be safe to assume that the plant likes to move. Rounded leaves along the expansive stems, reaching an attractive earth cover and flower basket accent. Originally from Europe, it is considered an invasive species in the USA. UU Due to its propensity to displace native plants. Although it is easily removed from the ground, Jenny's drag is more suitable for containers or as a turf replacement.
Garden of divas
With a high level of care and attention, high maintenance plants will throw a lot of attitude their way if they can not meet their demands. Instead of wringing your hands over these premium donuts, it may be better to plant relaxed flowers.
9. roses (Rosa spp.)
Despite being exquisite to the eye and extraordinarily fragrant, all types of rose bushes are delicate and need many pampering. For flawless flowers, you must ensure that the soil is deep, loose and enriched with compost, plan and space your plants properly so that the roses receive a good flow of air, irrigations twice a week and frequent meals, regular pruning and dead heads (look at those thorns!), as well as the eternal challenge of preventing black spots and Protect them from aphids, Arabian spiders, and deer.
10. Gardenias (Gardenia jasminoides)
Terribly temperamental, gardenias require a perfect harmony of watering, sunlight, humidity, feeding, pruning and mulching to catch a glimpse of the striking white flowers that come in summer. Neglecting only one or two of the needs of gardenia and the whole plant will suffer.
11. dahlias (Dalias spp.)
Adding a touch of colorful joy to the garden, the dahlias range from small half-inch pom-poms to huge 10-inch "food plates". Apart from the usual irrigation and feeding routine, dahlias are prone to powdery mildew, blight botrytis, viral diseases and tuber rot. Gardeners will also need to exercise a lot of vigilance in combating aphids and thrips, which often require pesticides to be applied every week to prevent infestation. Prolonging flowers means a lot of dead head and as the dahlias grow and become massive, they will have to be supported by stakes to keep their succulent stems from splitting in half.
