Only grows in a greenhouse over the winter months, Can be kept outside after danger of frost has passed or in a bright tempe controlled area of the house. Tends to get quite large, so it needs a big hanging basket, regular fertilizer or slow release is beneficial for this type of cactus. Since this is a tropical cactus, it will require regular moisture with a well draining type of potting soil(add perlite or pumice to the mix , not sand). I like to use a good quality soil from the garden center.

The size and beauty of this plant's flower is well worth the years it takes to come to flowering. It flowers once yearly but lasts only a very short time, sometimes just one day at full size. The size of the bloom is so awesome, up to 12 inches! It blooms in the fall around mid September.
The plant prefers full sun in the times of the day when the sun is not as powerful, early morning and late afternoon. Direct full sun can damage the plant. The scent is so intoxicating and fills the room. It has been known to grow up to 15 feet.
Plant is not toxic and is used medicinally in extract for angina, edema, rheumatism, kidney congestion, nervous headache. It is a tonic herb that stimulates the heart. Needs temps above 50 degrees (f).
