Planting Guides

Twinspur (Diascia) are a group of showy annual and perennial species native to southern Africa. Preferred growing conditions:

  • Plant in compost-enriched garden loam soil. Avoid clay. Diascia grows well in with full sun to partial shade conditions.
  • Mulching is beneficial using common mulch materials.
  • These plants like moderately moist soil and appreciate regular irrigation when conditions are hot and dry. They won't need much extra water in the Eastern US.
  • Fertilize lightly in fall with Yum Yum Mix/compost blend.
  • Special comments:

  • Deadheading will encourage extended blooming over the summer growing season. Cut back to just above the ground in early to mid-spring.
  • Diascia spread gently via underground stems and can be divided in the spring to control the plant spread and propagate additional plants.

I used several Diascia "Coral Canyon" in large half-barrel containers. They looked great all summer. The flower color is fantastic! these are coming back this spring. I also planted some in the ground, and these did not grow as robustly in my clay soil, but still looked nice, though may not have made it through the winter.

This could be a good plant for a new gardener looking for low maintenance, spreading flowers. Beware that it will take over nearby areas and choke out other plantings regardless of the space you give coral canyon twinspur! I found it to be frustratingly hardy and easily established. I will be tearing out all of it from my CRC garden in a box and donating or relocating it.

    Very healthy little plants on arrival that thrived in my PNW partly shady garden with relatively poor soil. Blooms into fall. Overwintered well now I have a nice mass of plants and I can tell it's really going to be magnificent in its second year.

    I bought this one over five years ago and planted in clay/gravel bed, mulched in pea gravel, next to a flagstone patio near a south facing wall. (Hot, harsh, dry) OMG, this plant blooms for weeks in a gorgeous coral carpet. I cut it back after the first flush and it reblooms most of the summer. Slowly spreading, a bit invasive, but that is OK for this spot. I cut it back about March when it starts to green up. It is planted in front of a hardy shrub rose and makes a gorgeous compliment.

    The blossoms like similar - quite small but a bright pink. I ordered these because I was looking for an upright pink flowering plant for one of my flower beds, they never grew much taller than a few inches and some of them that were a little longer lie on the ground like a ground cover. Over all the only thing that looks the same with what I recieved and the picture is the bright pink blooms

        This plant just keeps "going and going." It produces a lot of blooms without deadheading (which is good as the flowers are small).

                It seems to be surviving our Oregon rainy winter very well.

                This next growing season should tell if it is going to thrive.

                    Q & A

                    Suggested Companion Plants:

                    USDA Hardiness Planting Zones

                    To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

                    • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
                    • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
