Q.Best Climber
I want to grow a climber on a tv antenna tower. Postition is in a lawned area, so it cannot be too competitive. It is in sun most of the day, a sheltered area (house and fence on two sides). Looking for easy care and quick growing. Located in South Australia . Hot dry climate (summers of 40 degrees celcius, some frosts in winter)
I recommend something called clematis! There are many cultivars available in many colors. They will do quite well in your area. Here is an article for more information: https://www.gardeningknowhow.com/ornamental/vines/clematis/growing-clematis.htm
