The tuberose is planted in rows in a similar way to the jasmin. The
stems thrown up by the bulbs bear ten or twelve flowers. Each flower
as it blooms is picked off. The harvesting for the factories takes
place from about the first week in July to the middle of October.
There is an abundant yield, indeed, after this, but it is only of
service to the florist, the valued scent not being present in
sufficient quantity. The flowers are worked up at the factory directly
they arrive by the enfleurage process.
