Thank you all, I have a purple one blooming now, will share the pics soon...
BTW I bought these in 2005 but due to my lack of experience then and space constraint, I was planting them in locations with lesser sun, so they bloomed very less and shorter spikes. Every year after spring I dug up & save the corms and this year was just perfect for them, every corm with size above 1 inch has formed the spikes..
Neal, I planted them rather haphazardly in a small area but the way they performed, next year I will be giving them the whole bed
