Genus: Twinspur

Diascia

Twinspur (Diascia)
dy-ASS-see-ah
Scrophulariaceae
Plants in this genus are softly textured annuals or tender perennials that produce delicate, loose spires of flowers in summer and fall.  Diascia is at home spilling onto a walkway or filling in between more structured plants. 
Noteworthy characteristics:  Colorful spires of 5-lobed, hooded blossoms with backward-pointing spurs.
Care:  Grow in fertle, moist, but well-drained soil in full sun. May stop blooming during hot summers. Shear the spent stems to produce another flush of blooms.
Propagation: 

Sow seed when fresh or in early spring; take softwood cuttings in spring or semi-ripe cuttings in summer. Easy to overwinter in a greenhouse.

Problems: 

Slugs, snails.
