I live in Nanaimo BC Canada and have two Cardios - one is presently bloooming and the other resting until next year! They seem to share bloom years!
If anyone would like seeds I'll mail you some - no charge - as each bloom yields hundreds and hundreds per pod after flowering~

I purchased this plant because of it's beautiful glossy leaves. I didn't know what it was. It died off at the end of the summer, but came back the next year. It grew and grew and grew until it was about 6 feet tall. Then these long tubes began to form at the top. I still didn't know what it was. When these tubes (20 to 25) of them opened, I then realized it was some kind of lily and found I had a lily giganteum.

When it died off at the end of summer, I cut down the main stalk. This month, it has started up again, with 6 or 7 shoots around the old central stalk. I realize now, I should have divided the bulbs, which I assume were under ground, as nothing was visible. However, as they grow so quickly, the new shoots are already 8 or 10 inches tall. I wonder if I can d... read more

I just bought a bulb and took great care planting it on a rotten steak with lots of natural fertiliser on a little heap of well drained soil in full shade, just as the seller told me to. Seeing all those flowering beauties in sun or half shade makes me wonder if I put the bulb on the right place in my small urban peace of blue clay....

I have been growing Cardiocrinum giganteum in Lillestrøm, Norway (outside Oslo) for three years now, and it is really one of my favorite plants in the garden! The climate here is norwegian zone H4, equalling USDA zone 4b I suppose. Last winter we experienced -34 degrees Celsius (-30F) on two days, with -30C for several days.

After reading about the Botanical Garden in Gothenburg, Sweden were growing this species, with a winter covering of 50 centimeter (20 inches) hayballs, I aquired some bulbs from Great Britain, giving them a light but protected situation in the center of our garden, in fluctuating shade from a tree. The bulbs were planted in a raised bed 40 centimeters tall, built of solid blocks of peat, in a soil consisiting of rather old peat, some sand and a very ver... read more

I have personal experience with all this plants dos and don'ts. Do get fresh seed. Don't pay a fortune for a few seeds, as not all are viable. Some have better embryos than others The ones I bought (20 seeds for a fortune) had no real embryo (which is a hard bit in the middle). They were blank or had a brownish mark--no good! Needless to say I planted them (the seller most likely will not tell you they have to be fresh) at the wrong time, waited a year with no results.

I bought a mature bulb, which only grew to a stretched 3 feet, but had good flowers. They will not establish well if mature and will not grow tall. Had plenty of seed, which I took off early Nov. as seed pods split, then sowed some by late November, discarding hundreds.

A large bulbous plant from Southern China and the Himalayas.

Has large, ovate to heart shaped, glossy, deep green basal leaves, also carries smaller stem leaves. Bears tall stalks of white, trumpet shaped flowers that are heavily fragrant.

Flowers June-August

Likes a well-drained but moist, fertile soil in light shade.

This plant begins to die when the flowers are developing on the stalks (monocarpic), no amount of persuading will keep them alive once the seeds have been shed. However, when the flowering bulb dies, it has usually produced several bulbils/offsets around the old bulb which will flower in about 3-4 years from that point.

The plant will naturalise with these offsets but to have a year on year flowering ... read more
