Once called "outhouse flowers", stunning hollyhocks were grown around outhouses because hollyhocks were tall enough to cover them, and also as a signal to guests where they were located. This hollyhock has a long bloom period, too! Fairly drought tolerant but performs best with ample moisture and rich soil; otherwise, practically care free.

• Harvesting: For longest-lasting cut flowers, harvest when 1/3 of the flowers on the stem have opened. Harvest in the morning; cut stem at an angle and immediately place in a bucket of warm water. Before placing in a vase, dip the stem end in boiling water for a minute, or sear it over a flame for 20 seconds; this will stop the flow of the milky sap so it does not clog the stem.
