I have them indoors. I have about 55 plants, but they're all indoors (and mostly tropical), since we rent and the landscape around our house is pretty full and set up already. Although, my mother in law and I split the package of bulbs and she intends to plant them as a border/sun-block for a window well for a basement bedroom. We haven't warmed up yet, but we do live in the desert of Washington and we hit triple digits often in the summer. Would you suggest she start them indoors first, or do they sprout quickly when planted directly in the ground once we warm up? I'm sure she'd love some advice, and thank you all again for being so helpful!!
