I found this information on zantedeschia rehmannia:

"Tubers usually develop 2 to 3 leaves initially, which are followed by a flower stalk. If the flower is cut, another leaf will develop from the axils of the first and second leaf, followed by another flower. If multiple stems develop from one tuber, a flower will develop from each stem and if given adequate space and light, 3 flowers can be expected from each stem.

Z. rehmannii has light to dark pink flowers, a semi dwarf growth habit and a non-monopodial character with multiple stems from each tuber during the first year. This species is widely used as a flowering pot plant because its multiple stem growth habit fills a pot rapidly. The plant has an attractive lanceolate leaf with white markings or streaks throughout the leaf blade. It takes an average of 60 to 70 days for plants to flower when the plants are started from dormant tubers.

Apparently, like most plants, it does help to promote further bloom by deadheading spent flowers. Do you fertilize them at all? You might try a high phosphorous fertilizer every couple of weeks at half strength as well.

Dear Susan,

Thank you SOOOOOOO much for you quick and detailed response. I can't wait to give this a try next year and see if I do a better job.

Thank you!!!!
