According to an enployee of the Hortus botanicus in Haren (Groningen, the Netherlands) I have a Cycas circinalis. It has been actually quite a challenge to me to determine what the botanical name is of this plant. I obtained the plant about thirty years ago at the flower shop in our shopping mall as a mothers day gift. Of course my mother has taken proper care of the plant and at a certain time it produced two offsprings which we were able to isolate. One of them died and the other one grows in my home. My mother is 88, so in the end the original plant will also end up at my place. As it is a tropical plant, it grows indoors most of the time, but mine I put outside for the first time, because it's such a crazy hot and dry summer in Western Europe this year. This year I repotted the plant, ... read more

I bought my Sago about 4 yrs ago after having visited a friend of mine in Austin, Tx. His was on the patio just existing. Filtered sunlight, and watered when he remember to go out and do so.
Well, I thought i'd give it a go ! It's doing very well. Had to get used to is watering needs. Very fussy at first, and now I know when and how much to water. It gets all day shade then full sun from about 430pm to sundown. I know, its the worst sun, but its thriving very well. Ive never trimed it, but on occasion some of the needles burn. I think it would die or at least hate me if I ever chose to move it from its area of the patio to which it has made it its home.

As my photo says..five years of no flush in ground and in part sun,and the plant still clung to life with a will to live. Dug up and re-potted,then placed in full sun-it flushed small,tiny stunted fronds last year.This year it has flushed again..two years in a row. The second flush fronds are much smaller then average for this Cycad but its going in the right direction! And the fronds had the right form.

I even fertilized it..I never thought that day would come.

btw,When it was in a tropical greenhouse,it would flush 3 sometimes 4 times in a year. An easy cycad for greenhouses or sunrooms.

This is hardier than the zone report claims. It's easily hardy in zone 8 and with covering in the Winter zone 7.

I live in Srilanka. In Srilanka, the tender leaves of Cycas circinalis are used in curries and soups after boiling in water for abuout half an hour. When boiled the toxic effect is removed.
Dry seeds are grinded and steamed the flour before use
We make a kind of bread called MADU PITTU.

A native to India, the Cycas circinalis or Queen Sago Palm is actually a Cycad and not a Palm.

Although this plant does not currently appear on any lists as poisonous, it appears its seed may be toxic to animals as well as humans yet I noted an entry in which some palm seed was actually ground and used in a bread meal.

The Queen Sago has dark green attractive foliage and is slow growing. It does not branch as does the King Sago. Both appear to be very susceptible to scale so probably not a great plant for North America unless you like to spend lots of money maintaining its health with little or no guarantees the plant will survive.

Cycas circinalis is NOT the same is C. rumphii, although most plants identified as C. circinalis are really C. rumphii or something similar. The true C. circinalis is actually a pretty rare plant, with a much smaller habit and smaller leaflets and leaves than the massive C. rumphii commonly used in landscaping in the more tropical areas of the world. However for now, we will just keep this identification as is since 99% of the world knows this plant by this name, incorrectly or not.

This is another common landscape cycad, as well as a common potted plant in the warmer areas of the world. It's cold hardiness, as well as its tolerance for hot summer sun do not match the much more common Cycas circinalis or Sago Palm. But it is s... read more

The queen sago is larger and softer than the king sago. The fronds are often 6' to 7' long and quite feathery. It sets seeds a bit differenty than the king, also; they cling to long, exposed ribbon-like structures. The seeds are green and about the size of a goose egg when ripe.
