You are correct that you need to shop for the Serena series of Angelonia, but you may have a hard time finding it at this time of year. If you type in 'Angelonia seeds' into google, you'll come up with numerous options, with a wide range of prices. Be sure to buy pelleted seed, as they are quite small and would be difficult to handle.

I have not grown these myself. But I wouldn't expect them to be difficult, but they take a long time (from my reading) to bloom from seed. Since they can't be sown or planted outside until all fear of frost is past, that makes it a bit difficult. Unless you have a sunny greenhouse.

Does anyone have any hands-on experience to share?

They are on Swallowtail Garden Seeds website. I have bought a lot of other seeds from them and like them. The zinnia seeds have been fantastic.

I love the serena series, and was dubious when it was first introduced, because the industry is always coming up with seed-grown lines of plants normally propagated by cutting and most I've found aren't as robust. Well, Serena made a believer out of me. They're superior to the cutting grown varieties I used to order as cuttings.

They are not hard to grow by seed. They are just wonderful, very underused plants..........a staple selection in my landscaping line.
