Diascia, sometimes called twinspur, is a delicate, frothy type of plant. Some varieties will spill over pots, and others tend to grow more upright. It's a relative of the snapdragon and comprises about 70 different species in South Africa, where it is a native. The varieties of diascia you see popping up at garden centers have been bred rather recently. They’re coming out with new colors and better bloomers every year.

How to Care for the Plant
Water
Diascia needs regular water, but it doesn’t like to sit in wet soil. If growing in a container, make sure there are good drainage holes. As a general guide, water when the top 1 inch of soil or potting mix feels dry.
Fertilizer
A time release fertilizer seems to work best. If you prefer to hand-fertilize, don’t overdo it or you’ll get leggy plants. Leggy plants can be pinched back, to keep them attractive and full.
Sunlight
You'll get the most blooms by keeping your diascia in full sun, but in really hot weather, the plant will do best when grown in partial shade, particularly afternoon shade.

Soil
Diascia prefers a slightly acidic soil pH. Something between 6.0 and 6.5 seems to be ideal. The soil should be fertile and well-drained.
Temperature
Diascia prefers cooler temperatures, and it flowers best in the spring and fall. If your plants start to fade in the heat, cut them back to a few inches and keep them watered. They will perk back up when it cools off.
