Marketing manager Stuart Lowen's top picks are the Verbena EnduraScape, Osteospermum '3D' series and Impatiens Bounce series.
The verbena, introduction in 2014, is robust with good spreading ability, he said. It does not grow above 15-20cm and provides good parks ground cover. The Osteospermum '3D' series has double flowers that do not close. It comes in five colours.
Bounce is an interspecific hybrid impatiens that is resistant to downy mildew. It grows in sun or shade and bounces back when watered after drying out.
The themed gardens include Balcony, with black, white and silver. Lowen said by changing one element it has created cool and warm red and orange as well as cool blue and lavender moods.
The contemporary garden has pastel shades while the sensory garden is tactile. The Bollywood garden includes magenta, orange and yellow. The seaside garden is blue, white and yellow.
