well i have two limiting factors but i want to make sure they make sense 1. radiant energy 2. soil reaction

Yes those two make sense the amount of sun it gets can really affect it and the soil reaction can change pH if too many pollutants are reacting with the soil and if the pH changes too drastically then the flower won't grow

@geny55 $$\large\rm\color{green}{Nice~to~meet~you~!}$$ From Previous Help : http://broome.soil.ncsu.edu/ssc051/Lec3.htm Name all the factors affecting plant growth temperature, radiant energy, moisture supply, composition of the atmosphere, soil aeration and soil structure, supply of mineral nutrients, biotic factors, soil reaction, absence of growth $$Temperature$$ factor measure of the intensity of heat. Directly affects photosynthesis, respiration, transpiration (loss of H2O), absorption of water and nutrients $$Radiant~Energy$$ factor quality, intensity, and duration of light important for photosynthesis $$Moisture ~Supply$$ factor Restricted growth by low and high levels of soil moisture. Can be regulated with drainage and irrigation. Good moisture improves nutrient uptake. Fertilizer needs moisture to work efficiently. $$Composition ~of ~the~ Atmosphere$$ factor How much CO2 in the atmosphere affects growth. If level is low it is a limiting factor of photosynthesis. Can increase CO2 with decomposition of moisture or plant residue. $$Soil~ Aeration~ and~ Structure$$ factor (clay, rocks, sand, etc) compact soils have poor aeration. Pore space is occupied by air and water. $$Supply~ of ~Mineral ~nutrients$$ factor essential nutrients- any element that functions in plant metabolism. Also, non-mineral nutrients carbon, hydrogen, and oxygen $$Biotic$$ factors disease, insects, weeds, etc.. weeds compete for nutrients, moisture, and light $$Soil~ Reaction$$ ph influences availability of certain nutrients, (ex: phosphate likes low acid soils; Disease affected by ph) $$Absence ~of~ Growth$$ factor restricting substances -aluminum, lead, nickel $$\large\rm\color{green}{Hope~It~helps~!}$$
