Is this a weed?

Jenny from

We are often asked "is this a weed?", so we are planning a weed identification guide for our website. What plant in your garden is giving you trouble? Are you wondering if it is a weed? We would love to see photos of your problem plants.

The best definition of a weed is that it is a plant in the wrong place. Any plant may be desired and manageable in one situation, (perhaps on the other side of the world:) and a problem in another situation.

Nevertheless, it is sometimes useful to know that a plant is known to be a problem elsewhere. If it is giving you unwanted work, you may not be the only one reconsidering its place in your garden.

In addition to the better-known weeds such as wild ginger, Tradescantia, pink jasmine, Japanese honeysuckle, privets and many others, recently in our clients' gardens we have learned of a few more plant species causing significant loss of space and damage to wanted plants in some local gardens.

One was Tecomaria capensis/Tecoma (aka Cape Honeysuckle, a common hedge plant with hidden runners, which if uncontrolled spreads new plants and also grows as a vine).

Another was Thunbergia vine. One of many different plant species around the world known as Black-eyed Susan, this one is a rampaging vine.

Below: Photos of a Tecomaria hedge on a street berm, where it is controlled by pruning. Any new plants shooting up in the grass would be mown down.
