Most of my Lilies bloom in July and are done by august 7. the Stargazers and other Orientals bloom end of July for me. I have a few Trumpets that bloom in early August. But if there are any Liliums (you are NOT talking about Daylilies right?) that bloom after mid august I want some too. The American Hybrids bloom first here in late June early July. DAylilies will bloom thru mid september if you want those.

Scherazade and Black Beauty are my two latest bloomers, blooming late July to early Aug. I believe Rubrum may bloom later: I don't have a long enough growing season for some them to "ripen" their foliage and feed the bulbs.

Hi Finchelover,
Of the hybrids, Orientals are later blooming. My Stargazers have just started blooming and should be shortly followed by my Siberia. Both will be finished by early August.

Lilium Speciosum (Rubrum or Album) is one of the latest blooming lilies, but here in Maryland it begins blooming in the first week of August. It would be a bit later farther north. Formosanum is the absolutely latest blooming lily that I know of, and may, depending on your local conditions, bloom in September. However, it is not particularly cold hardy, since it naturally has a small bulb and doesn't have much time to build up after blooming before Fall sets in. Mine aren't even close to blooming yet (i.e., the plants are still gaining height with no buds evident so far).
