The top five favorite photoes are: 1.Canna indica-near-blossom 2.Farfugium japonicum-near-blossom 3.Bidens alba-near-blossom 4.Setaria palmifolia-far-not blossom 5.Crotalaria pallida-far-blossom. The top five not preferable photoes are: 1.Bryophyllum pinnatum-far-not blossom 2.Celosia argentea-near-blossom 3.Miscanthus floridulus-near-blossom 4.Miscanthus floridulus-far-blossom 5.Alocasia macrorrhija-near-not blossom.
