"The best time for sowing Ipotiuva quamoclit, and rubro carulea for planting in the open air, is the end of February. They will both succeed under similar treatment, viz., to sow them in a gentle hot-bed, to pot them oft separately, and encourage their growth until the end of May, when they may be planted out in light rich soil in a sheltered situation." - Gard.
