Phitrantra can be pretty quick too, depending on the variety. There are maybe 12 reds and 3 scarlets in the yard and they all started around 3-4 years and 4’ from seed. A few phitrantra started at 3 years and 2’. All planted in ground at mega tube size though, so a little different from pot culture. Other honourable mentions for me have been aureana/phitrantra c16 (4 years 4’) and surprisingly trunciflora rajada and one that was sold on the forum here as “trunciflora cafe” a while back (4 years and 5 years).
