Wish I could help. Have you tried posting your question on the Sources Forum?

There are a number of west coast wholesale sources, but I find nothing for your side of the country. Hybrid phormiums tend to be grown from divisions rather than seed - it takes a long time to raise one from seed and hybrids will unlikely come true to form. You might try looking for the cultivar 'Shiraz' - much more readily available and very similar in appearance and size. 'Amazing Red' is also a good substitute.
