This is a Cylindrical Snake Plant. They are tropical and usually require being indoors. They prefer "bright shade." As far as where to get them... We don't recommend places to purchase. I can say that you might have luck on reputable nursery websites or your local nurseries may have them as well.
You might try asking where the plant that you saw was purchased.
