Great information Hetty, Ken and Gigi!
Mike, my cuttings sit on my covered portion of my back deck, and get dappled afternoon sun. Our weather is colder here, and we had nights going down into the 40's still in June. The Hawaiian cuttings were planted on June 29th, (pic #1) and this is as far as they have gotten. At least Lei Plantation (#2) has an inflo. The 3rd picture shows my cuttings compared to the rooted cuttings that I got from BBB at the end of July, and potted up in early August. The BBB plants haven't put on much growth either since being potted, and they have been in full sun. We've had rain for the past 3 days, we didn't get out of the 60's on Friday, and we hit a balmy 71 degrees today.
Picture #5 shows how much my cuttings from a co-op have grown since being potted in 2011, these were potted up today. The Riviera Rainbow that I got from Hetty last September has also done very well and got repotted today as well. Pictures #6 and #7 shows how much growth the plants have since being started as cuttings in 2008.
