It is well known that the double tuberose will occasionally revert to its original single condition. The single form is not considered as desirable as the double, but it has one great advantage in this, that it is nearly two weeks earlier in flowering. This is worth a great deal to those who desire early sweet white flowers. The Pearl, on the other hand, is a later bloomer than the ordinary double kind, and this is to be regretted, as its dwarfness renders it so far the best for forcing. It is nearly four weeks later than the single.
