No these plants do not fit on a windowsill. The Claudio #1 has excellent flower count, it appears 7 on 1 infl. , but I am definitely partial to the Claudio's Child, the form appears superior and color saturation is better. Achieving high flower count takes some years for purpurata, I am now just getting a good count on a werkhauseri striata, and it has taken about 4/5 years to get there. Post this weekend , flowers just opening. Leslie plant, he will get a surprise on posting. I also have a gaskelliana concolor now blooming for the third time, 1st flowering, I would have sold it away, 2nd flowering why are we bothering with this, 3rd time better flowering and good flower count. Patience, patience, patience. Striatas last year bloom.
