A couple of years ago I did grow Parks 'Ultima Morpho Blue' without much difficultly and they were gorgeous. Definitely easier to do for fall bloom too, that way you can start them outdoors (I have better luck in containers than direct sowing). They're said to require darkness to germinate, and some folks insist you've got to cover the containers, but I just lightly covered the seeds with potting compost. I figure that's how nature does it, and they germinated great. In late spring/ early summer some of the seed companies have sales too, so you can often pick up those for summer sowing at a better price.
