Bought plant in a one-gallon pot from a local nursery. Was horribly, horribly root-bound inside pot. Cleaned off all coiled roots, planted, fertilized and it has SOARED! About 6 feet tall by 5 feet wide now. Blooms all year. Planted in part shade/part sun on northwest side of house (California). Doing very well!! :) Rusty

I cut back much of the plant and repot it in a larger pot. It bounced back immediately with new growth and is che... read more
