Too Much of A Good Thing? Keeping Invasive Perennial Plants in Check

2009-05-08T10:54:00.000-07:00

There are many advantages to gardening perennial plants. For example, perennial plants are often much easier to care for and propagate than annual plants. But this advantage can often have an unintended disadvantage, when certain perennial plants begin to overtake your garden, yard, and perhaps your neighbor's yard as well. Many a gardener has had their garden overrun by mint and other rambunctious perennials, but there are ways to keep invasive perennial plant species in check.

Besides mint, some other very common invasive perennial plants gardeners should keep an eye on include Bamboo (Arundinaria), Garlic Chives (Allium tuberosum), Borage (Borago), Bee Balm (Monarda), Perennial Sunflowers (Helianthus), Freesia, Evening Primrose (Oenothera) and Tansy (Tanacetum). This is not a comprehensive list, however, and you should always check when adding a new perennial plant specimen to your garden as to whether its growth habits is invasive or not for your area.

Not all of these plants are invasive in all regions, either, since the success of many perennial plants is determined by regional factors. Plants that are not hardy, will not be invasive in cold zones, while those that need winter dormancy do not usually pose a threat in fair weather regions.

If there is an invasive perennial plant for your region that you do want to grow in your garden, there are ways to help keep the species in check.

Consider planting the invasive perennial plant in a large container set in the ground. The container will keep the roots from spreading into nearby garden patches, thus restraining the overall growth of the plant. This a method that is particularly useful for gardening perennial plants like mint - provided you also keep a watch on any runners the plant may send out that reach beyond the confines of the container, and you also make sure the drainage holes are not so large that the roots can grow through them.
For perennial plants that spread through seeds, removing seed heads when they are forming is probably the best way to keep these plants in check, although for those that propagate only through seeds this will also disrupt their perennial habit and you may need to replant the next year.
Regular plant dividing and the weeding out of invasive seedlings are another way to keep your invasive perennial plants in check, and it will help keep your perennial plants healthier and more productive as well.
Finally, check with your local plant supplier to see if non-invasive varieties of the species are also available. Often there will have been varieties developed specifically to be less invasive in growing habit.

Hopefully these tips will help you be able to enjoy your favorite perennial plants that also have invasive growth habits.

Poisonous Perennials

2009-05-05T20:30:00.000-07:00

When you are gardening perennial plants, you should try to keep in mind the safety of the plant species in your garden. If you have young children, or pets, special care should be taken. You should be committed to learning what plants you have growing in your garden that have poisonous parts to them, teaching children about the dangers of plants and eating them, and keeping poisonous plants, seeds and bulbs out the reach of pets and small children.

To help perennial gardeners with this responsibility, I thought I would compile a list of some of the more common poisonous perennials you might already have growing in your garden. This is not a comprehensive list! There are many more dangerous plants, including perennials, that can pose a threat. Do your research when selecting a perennial plant, and make sure you know what you are planting.

Here are a few perennials that are either all or partially poisonous:

Bleeding Heart - all parts are poisonous
Buttercup - all parts are poisonous
Clematis - all parts are poisonous
Columbine - all parts are poisonous
Ferns (some species) - all parts are poisonous
Hyacinths - all parts are poisonous
Iris - all parts are poisonous
Lupine - seeds are poisonous
Narcissus - juice is poisonous
Tansy - all parts are poisonous
Wolfbane - all parts are poisonous

Gardening Perennial Plants Book Review: Perennials for the Backyard Gardener

2009-05-04T11:26:00.000-07:00

Perennials for the Backyard Gardener, written by Patricia Turcotte, would be an excellent investment for your gardening perennial plants library. The book is divided into two main sections. Part one deals with designing and planning perennial gardens, while part two profiles perennial plants (divided into five categories: bulbs, low ground covers, middle-range perennials, high-growing perennials and biennials).

The book is written in an easy to read style, and is filled with drawings and photographs to illustrate topics and provide examples. The author tries to anticipate what kind of questions perennial gardeners might have, and provide sensible answers to these questions. Some of the sections I found most useful dealt with designing with perennials and propagation.

One downside of the book is that it focuses heavily on perennial flowers. Perennial vegetable species are not mentioned at all, nor are many evergreen perennial plants profiled in the book. Still, much of the information about planting, propagating and caring for your perennial plants are applicable across the board, and because of this I feel this is an excellent resource on gardening perennial plants.

Gardening Perennial Plants: The Basics

2009-04-22T22:21:00.000-07:00

In the past decade there has been an explosion of interest in gardening using perennial plants. Some gardeners are attracted to perennials because they seem relatively easy to maintain compared to annuals. Others love the color and reliability of many perennial garden plants. And still others are impressed by the adaptiveness of different perennials to native environments, and the ease of landscaping even very shady areas using perennial garden plants.

Technically, perennial plants are plants that do not die after a single season's growth, but instead regrows each year without having to be replanted. Perennials cover a wide range of plant species. Most trees and shrubs are perennials, of course, but when people speak of garden perennials they are referring primarily to bulbs, several vegetables and flowers.

Most of these garden perennials are “herbaceous,” meaning that the stems of these plants tend to be green and pliable, unlike the brown and woody stems you find on trees and shrubs. The soft, green growth will usually die and disappear in the fall, but underground the roots will remain alive and well, and ready to bring forth new growth come spring.

A common misconception about gardening perennial plants is that they are maintenance free. Many beginning gardeners may mistakenly assume that once a perennial is planted there is little to do. However, most perennial garden plants need some care each year, including feeding, staking, dividing and cutting back after blooming.

Those interested in perennial flowers should also be aware that unlike annuals, most perennial garden flowers do not bloom throughout the season. Instead, perennial flowers tend to have a short, but often spectacular, flowering period.

Despite the effort involved, many find gardening perennial plants to be a very rewarding activity. I hope you find the information on this website of use to you in your perennial gardening endeavors. On the right sidebar you will find many links to articles that contain important information about gardening with perennial vegetables and flowers, ideas about how to create a shade perennial garden, and useful links and resources for the perennial gardener. Happy gardening!
