For best reults, it should spend three months of the summer outdoors in the full sun. Another thing this plant needs is lots of room. It can grow up to three or four, sometimes five feet high. It likes a moist loam, with good drainage. Use a slow release fertilizer every three months during the growing season.
Mist leaves occasionally.
This is not an easy plant to grow. The attractive foliage cannot satisfy when you know what lovely flowers it can produce. But you cannot rush it. Take care of it. And, as I mentioned earlier, be patient, and the flowers will come.
