The Turnera ulmifolia plant has surprised me with its quick growth .I had a friend strike a cutting for me about 3 months ago .When John planted it, the hight was a single stem1 ft tall . when it
started flowering there was 1 flower per day[last only 1 day] I pinched the top of the stem out and now it has 4 branches ,is getting bushier and has 5 flowers every day. Really quick results
and I would say it would strike well.
