Here is a pic of my best blooming Rhythm and Blues taken back on July 14th. It took quite some time for it to grow and bloom, much slower than all my other Salvias.
I grew/am growing two seperate Rhythm and Blues. The second plant has grown even slower and bloomed significantly less. It bloomed about 2-3 weeks behind the first one and sent up about 2-3 blooming stalks that were about 4 inches high.
The one that bloomed better had about 7-8 blooming stalks that are about 1-1.5 feet long. See the two pics below. Both plants have had some yellowing leaves all season long. Both are growing in the same potting soil same sunlight and water. In fact I was expecting so much from them I placed them in front of the main entrance of my house hoping they would WOW all those who entered
They have not
last years Amistad and Wendy's wish did more WOWING lol.
Not quite sure what to do with them or if I'll try them again. A little disappointing. I have heard from others a similar tale of slow growing and slow to bloom. Maybe we expect too much from these not sure?
I may go with more Blue Ensign next year, Amistad, or Elk Argentine Sky. Not sure! Hope that helps.
