Hi Rod, just wondering where do you buy your seedings from? Many thanks, Matilda

I am in sunshine coast north of brisbane. Q My rosella bush has lime green flowers with a very light pink tinge on outer edges. The fruit is of harvest size but the calyx is green and not red. Any ideas please before the plant becomes compost. Planted early sept. This is the second year this has happened. Seedlings purchased from nursery nearby.

I suggest you talk to the nursery people or to their supplier. Also maybe ring someone like Eden Seeds and see if you can talk to someone who knows something about growing Rosellas. Maybe they need time to turn red it does say 5-6 months to harvest.

Are Rossella roots invasive
22 Feb 21, colleen (USA - Zone 10b climate)
I have not found the roots to be invasive at all. They tend to form a main tap root with tiny roots branching out from it.

Hi Rhonda, I live in Caboolture, not far from you. Just wondering could we catch up some time to exchange ideas about growing Rosella plants. Thanks in advance Rod

No Rhonda here in the last 50 comments. Start with good rich free draining soil. Add compost etc before planting. Plant at the recommended time. Water regularly - 3 times a week, longer waterings in summer.
