Grows to 4'-7' tall, white extremely fragrant trumpets, blooms in August, loves the heat, hardy zones 5-8. Have one trade of four bulbs. Prefer to trade for other lilies.
Only Lily I have for trade is stargazer. But do have fresh seeds stawberry foxglove -- gardiflora .. gorgious , tested for high germination. Also have Zephirine Drouhin rose cuttings, unrooted but they are easy to root. Or anything else on my trade list u like.
For some reason, I cannot reply to you. I would be glad to trade for some of the rose cuttings and your Grandma's Royals iris.
FYI, there is a Lilium formosanum and a Lilium phillippinense. They are not the same, although they are both in the same section.
