Ipomoea × sloteri is an allotetraploid[1] species derived from Ipomoea × multifida, i.e., descended from a hybrid of I. coccinea and I. quamoclit; it is sometimes referred to as I. x multifida, though technically that name refers only to direct hybrids of I. coccinea and I. quamoclit. It is a cultivated species with no natural range. Like Ipomoea × multifida, it is known as cardinal climber.

Description

I. sloteri is a climbing vine, growing up to 10 feet (3.0 m) in height; its flattened, twining stems bear alternate leaves. Like I. quamoclit it has palmate leaves with deep incisions, but the lobes are somewhat longer and the incisions somewhat less deep; usually the leaves have 3 to 7 lobes on each side plus a terminal lobe. Like both parent species it bears bright-red trumpet-shaped flowers; these have five petals, forming a pentagon shape when opened. A style and five stamens protrude from the flower. The plant first blooms in mid-summer, and keeps producing flowers continuously even without deadheading. The fruit are round and initially green but dry to become brown and papery; each contains two to four seeds, typical in shape for a morning glory.[2]

The seeds are fertile, and the plant breeds true. However, the seeds require scarification or soaking to germinate quickly, and may not germinate on their own in colder climates.[2]

As the parent species are both tropical, the plant is killed by frost, and can thus be grown in temperate climates only as an annual. It grows best in well-drained soil, hot weather, and full sunlight, and is somewhat drought-tolerant.[2]

History

I. sloteri was developed in 1908 by Morgan Sloter of Columbus, Ohio, who had been creating hybrids of I. quantoclit (as the pollen source) and I. coccinea since 1897; only in that year did one of his hybrid plants produce one fertile seed, from which I. sloteri derives.[2]
