Medicinal Herbs Versus Culinary Herbs
UNITED STATES—They are NOT the same thing! Many herbs can be useful for both culinary and medicinal applications, but the distinction between the two is very important. Culinary herbs are used to flavor foods. Medicinal herbs are used like pharmaceutical drugs; but they lack the main safety feature of standardization. That means that they are potentially toxic and seriously...
Herbs For Kitchen And Garden
UNITED STATES—Herbs might be in our garden right now, whether we are aware of it or not. Trailing rosemary happens to be a popular and practical groundcover, and some varieties grow as low shrubbery. A few varieties of thyme also work as ground cover for small areas, or between stones. Various lavenders are popular low mounding shrubbery. Quite a...
Concrete And Jungle Can Be Compatible
UNITED STATES—Concrete is one of the most common of landscape materials. There are probably more landscapes that include concrete of one form or another than there are landscapes that include lawn, and most landscapes include lawn. There are more landscapes that lack shade trees than there are without concrete. We do not notice it much because, once it is...
The Birds And The Bees
UNITED STATES—There is so much more to gardening than mere horticulture. There is so much more to horticulture than mere plant life. Plants get eaten by insects and animals, and also take advantage of insects and animals for pollination and dispersion of seed. Some of us who enjoy gardening also like to attract some types of animals and insects...
Naturalizing Might Be An Advantage
UNITED STATES—Of course, to the plants who do it, naturalizing is an advantage. To the rest of us, it is often a problem. The advantage to the plants who do it is that they move into new territory, make themselves at home, and probably do quite well with the new place. The disadvantage to everyone else is that naturalizing...
Overgrown Shrubbery Becomes Small Trees
UNITED STATES—Those of us with 'maintenance gardeners' are likely aware of how rare it is to find someone who knows how to maintain hedges properly. It seemed so simple years ago. Several identical plants could simply be planted in a row, and then somewhat regularly shorn for confinement to a prescribed space. They were not allowed to exceed a...
Tropism Gives Plants Some Direction
UNITED STATES—When a seed germinates, the roots know that they want to go down, and the new stem knows that it wants to go up. Going up sounds simple enough. Stems just go towards the light. How do they know where the light is while they are still under the soil? Well, new stems go upward for the same...
Cultivars Are The Real Cloned Mutants
UNITED STATES—It is not science fiction. It involves neither ninjas nor turtles. Cultivars really are mutant plants that can only be propagated by cloning. The word 'cultivar' is a portmanteau (two words combined into a single word) of 'cultivated' and 'variety'. Unlike other varieties of plants that can be perpetuated by seed, cultivars must be cultivated by unnatural techniques...
Gophers Go For Roots And Lawns
UNITED STATES—Who do they think they are?! This ain't 'Caddy Shack'! They have such attitude! Gophers move into our gardens and lawns, take what they want, and build their messy volcanoes of loose soil. They do not care how much work we put into our gardens, or how much we spend on nice plants, or how much we crave...
Hedges Are Like Green Fences
UNITED STATES—Hedges are a complicated topic! Like lawns, they are among the more functional features of a landscape. They can be used to provide privacy within, obscure unwanted views beyond, or merely to separate a large landscape into cozier or more functional spaces. Except for hedges that are grown for spring flowers or autumn color, most hedges are evergreen...
