Mary Ann I think they do sell the newer intro's as well to box stores, I don't know why else they would grow 10000 bulbs of a seedling before introducing it unless that was the case. There business is 85% commercial just a small percentage is retail for us Iris Lover's they have buyer's that come in and take ten's of thousands of bulbs at once like Dusky Challenger they will sell 30,000 bulbs in a year of it maybe more depending on the year can you imagine digging and moving those quantities every year
The trucks never stop moving during there shipping season.
I think there customer service is fantastic they always get right back to you and the quality is awesome hard to find anyone that will guarantee a plant will grow and do well for you but they do and if it doesn't they replace it you can't beat that customer service.
