These have been in bloom for about 6-weeks. Strangely, two of the three have, or are sending up, new spikes after the initial wave. ID: All noids, sorry! Culture information: Well I don't do anything to care for these, just leave them in the driveway exposed to the elements.
YOU have some good plants there , stake the flower spikes and repot them in to fresh media when the new growths start to show and you will have an even better show next year. Remember not to over pot ! You must have a green thumb that goes right up to your elbow!!! Good luck
