Comparing annual and perennial flowers is a little like comparing apples and oranges. Each type of flower has its own characteristics and advantages. Annual flowers are those that complete their lifecycle in just one growing season. In other words, you plant a seed (or a seedling plant), it grows foliage, then flowers, seeds and then the plant dies, all in the same year. Annual flowers tend to bloom from spring until autumn frost. Although they […]
Chilly days call for warming up with a steaming bowl of hot chili. And we can thank the peppers known botanically as Capsicum for that warm sensation. Although they are native to Central and South America, Capsicums traveled around the world before they were introduced to North American culture. Explorers brought Capsicums to Europe in the 1500s. The Spanish named it “pimiento” after the black pepper called “pimienta,” which is the unrelated Piper nigrum. As […]
Evergreens require a bit different manner of pruning than other landscape plants. Although a plant is not likely to die from improper pruning, it is important to note that most evergreens cannot replace lost growth the way that deciduous plants can. So while other landscape plants might be able to outgrow an errant pruning job, evergreens can suffer permanent disfigurement. Individual plants should be assessed for pruning needs. Evergreens that have been sheared into formal […]
Each year, the National Garden Bureau selects a flower to promote, and this year the annual garden flower known as vinca is the star of the show! Vinca is a popular annual bedding plant in the Midwest with loads of single-flower blooms in shades of red, pink and white. More accurately identified botanically as Catharanthus, there is much confusion regarding the name of this plant. Catharanthus is the sun-loving, summer-flowering plant that is grown as […]
Do you turn green with envy while admiring the neighbor’s garden but don’t think your thumb is green enough? Anyone can develop a green thumb, as long as they’re willing to invest a little time, patience and elbow grease. Good planning is essential to successful gardening. Start your garden off right by selecting a location that receives at least six hours of direct sunlight daily. Check the site for good drainage by making sure water […]
Many landscape plants will require pruning at some stage of their life. Plants may need to be pruned to reduce or maintain plant size or to remove dead or damaged material. Pruning is also used to reduce overcrowding and rejuvenate older, overgrown plants to produce more flowering, fruiting and/or leaf canopy. Using the right tool for the job will help protect both plant and human. Both the size of the material being cut and its […]
Instead of throwing out that pineapple top, turn it into a houseplant! Carrot tops and avocado pits can also be salvaged from the garbage pail to the ranks of houseplants. To grow a pineapple, cut off the leafy top, leaving about a one-fourth inch of the fruit attached. Scoop out the pulp and let the top air dry for a few days. Then, press the top into a pot or pan of moistened rooting media, […]
Christmas cacti are not only popular holiday gift plants, but they are also the subject of frequent debate among gardeners. There appears to be much confusion about these unique tropical cacti regarding care, maintenance and, especially, on how to get them to re-bloom. The following tips address the most frequently asked questions. We typically think of cacti as being heat tolerant, but Christmas cacti will keep their blossoms longer in cooler temperatures. Keep the plant […]
The recent warm spell has many a gardener wondering what to do about bulbs–and perhaps a few other plants poking their foliage through the soil. This is the time of year when we normally expect temperatures to be cold enough to signal the hardening-off period to plants. And for a brief while, it was cold enough to start that process. The longer the warm spell, however, the more plants have begun to sprout new growth […]
Although much of the vanilla used for flavoring and fragrance today is produced synthetically, natural vanilla comes from the seed pod of an orchid plant. Vanilla planifolia is a vigorous, vining orchid that can reach up to 300 feet in its native tropical American environment. The vine produces greenish-yellow flowers that must be hand-pollinated outside of its native habitat to ensure good fruit set. The pods grow to about 6-9 inches long and are harvested […]
