It may never bloom... I have mine out in full sun in Sacramento. Is there some reason you can't grow it outdoors?

I live in a studip apt in san francisco with no balcony. right now I currently have one huge Nepenthes alata, an orchid and an Abutilon growing on my windowsill

oh... WHERE in SF do you live? You MIGHT manage it in say the Mission, in the fog belt, I don't even know if you could keep it alive.... if orchids are doing well, I don't think a protea would. Proteas aren't really tropical, they like weather like here in Sacramento, hot and dry in the summer and cool in the winter.

I live downtown by union square. The window is east facing and gets a lot of morning sun, and then indirect light throughout the day. I leave my bathroom door open when I shower so my room can get more humidity. My Nepenthes is doing really really well, but my orchid is not. The leaves are all burnt, but it is growing a new bud of leaves. I think it isn't doing well because I don't take very good care of it, not because of the area. I rarely ever water it and I need to repot it.

I volunteer at the Botanical Gardens in golden gate park, and they have a beautiful silver King Protea growing there. It is not in bloom, but I love it's silver leaves so much.

Lucky you! I'd like to volunteer there! Do volunteers get cuttings? :o) Well... you know, you could try... why not? If it doesn't do well, you could send it to me! :D
