Which sunlover plant and shade lover plant grow the fastest?

Question

i need to do a science expirement and i need a sun and a shade lover plant which will grow at least 10 cm in 3 weeks after i planted their seeds?

give me some examples of the plants please?

Answer 1

I'd recommend some of the tall sunflower plants, as these can grow pretty fast, if given a sunny site and fed well.  Helianthus annuus is the botanical name of sunflowers.  

Foxgloves will grow in shady spots, so you could try with these too.  Digitalis purpurea.

Hope this helps.  Good luck!  Rob
