Not such a dumb question, we are SA temperate and depending where you are in it can have a 4 to 8 week difference on sowing and harvesting times. Through experiance over 10 years we have learned to use both Arid and temperate depending on month it is. But that was with the guidance of a friends son who studies climate and agronomy.

The first year I planted Rosella plants , that was three years ago The plants took a long time to flower and fruit These plants grew approximately 3.5 meters tall They did fruit ok though These were fertilised only with Searls Dianamiclifter pellets These plants were given to me by a friend . Last year I purchased seeds from CRT at Gordonvale These seeds shot in the pots in three days in good potting mix , they were planted out in about 3 weeks This time I mixed into the soil Sulfate of Potash as well as Dianamiclifter pellets And plenty of water The plants started flowering when 100mm 4 inches high and never stopped This year the same thing I think a lot depends on the Type of seeds and area you are in. Good Luck

Small ones could have been dwarf rosella. I have snow peas growing one grows 4' high the other doesn't start flowering until it is 4-5' high and grows 8"+ high.

I planted a Rosella suckling 6wks ago. The past few weeks a fungus had started due to the wet weather. I got that under control, I thought. I just noticed the new leaves are getting eaten on the tips and some of the leaves have "brownish orange scales" on the underside. I couldn't locate a caterpillar. Might it be a cutting insect? Help! it has been doing really well in the well prepared soil and drainage. Location outside of Bundaberg.
