Doug, what say you? Basically, that is true. 75 to 80% of S. m. k hold their leaves and pseudostem through the year until the "new" is ready to appear. At that time, the old "dies" away and the "new" starts up. Shortly thereafter, the "flower spike" appears. The "bulb" of this one is somewhere between a bulb and a risome. Scadoxus multiflorus forms more of a bulb, and it "buries" itself in the planting medium. DO NOT "OVER WATER" this bulb as it will rot if overwatered. There is also "miniature"/"dwarf" form of S. multiflorus. It is also more of a bulb, buries itself, and goes completely "dormant". I hope this "non-scientific" answer helps to distinguish between the two. Doug
