1) Curly Lion and Green Tiger are more than likely 'Cowardly Lion' and 'Marmaduke' respectively. They really aren't rexes but that isn't really important. Do a web search for both of these names. Cowardly Lion has some yellow tones to it but is more orangey brown in my opinion and Marmaduke is kind of yellow with red spots.

Cowardly Lion is semi-easy to grow and keep. Too much water can make it go downhill fast. Marmaduke is a wonderful performer in summer but is very temperamental indoors during winter. I think it may need a lot more humidity than normal house air.

2)Benitochiba usually blooms (pink) in the spring but may sporadically bloom. It is grown more for its leaves than its blooms anyway. It will usually defoliate in winter for a seasonal dormancy.

Looking Glass and Maurice Amey should bloom sporadically given the right conditions. They both have pink blooms too. Again they are grown more for their leaves. These two are notorious for mildew. They grow like weeds outdoors in summer but once cool weather hits, mildew can be a huge problem and may lead to their demise.

A lot of times these two are best grown as annuals unless you have the right conditions in your home for them.

3)Rexes come and go. Enjoy them for their beauty. If they have a name that is great. A lot are mis-tagged though. Some are hard to differentiate one from another similar one. Rexes are mildew prone too but usually can be kept through winter since they typically defoliate for a few weeks in winter.

4)Angel Glow is so new in the USA that I don't know if it is widely available. A few people have it. It is a Ross Bolwell (Australia) creation and hopefully it will go into TC soon and be available at next year's ABS convention.
