Holding a positive attitude is all the rage right now. "If you focus on the things you don't want, you will attract them to yourself" - is what's on many peoples' lips today. This no doubt is all very true, but without decrying the wisdom being imparted today, the amateur home gardener should be aware of the things that may be lurking in the backyard, some of which can actually endanger life and limb.
Poisonous plants
Admittedly, many plants are toxic to at least some extent. Some people are allergic to common favorites like Olive and Cypress trees. Furthermore, there is always the proverbial one in a million chance of a person being allergic to a particular plant that is not generally supposed to be allergenic. Taken to an extreme, we would be frightened of putting anything at all in the garden. There is of course no need for this. Nevertheless, common sense should prevail, and the life threatening species ought to be avoided. One such case in dry climate gardens, is the ornamental shrub Nerium Oleander, where all parts of the plant, if eaten, can be fatal. Even burning dry branches is liable to be dangerous.
Spiky and thorny plants
As with plants that posses some level of toxicity, the exclusion of every thorny species would mean that many excellent ornamental mainstays would be lost to the garden. Roses for instance, would suffer a banning order. Without going to such lengths, it is nonetheless prudent to avoid plants that can cause serious injury. The spikes of Yucca are horrific, and often spring out at a child's eye level. I am always horrified to see them at the edge of a lawn, where children are innocently running around.
Another horror plant is the widely used date palm. (Phoenix dactilyfera) It is totally unsuited to a small garden or to any narrow space. I personally know a 5 year old boy who is suffering one year on after being stabbed in the arm from a date palm leaf, for the plant is not only dangerously thorny, but highly allergenic as well. If you want a palm tree in the garden, choose a non-violent type like Archontophoenix instead. For similar reasons, the Pampas grass (Cortaderia selloana) with its razor sharp leaves, should only be planted where there is no danger of people brushing passed it.
It is worthwhile therefore taking an inventory of the plants currently in your garden. Spikey plants in vulnerable places should be removed, while an expert specializing in poisonous plants should be consulted with, in order to ascertain as to which are dangerously toxic to an unacceptable degree.
