they grow up surround my place. we dont know their name. and also dont know how to take care them. they just like bushes actually. the yellow one, only blossom in the morning, maybe for 5-6 hours. the purple one, blossom longer, but so thin, i think. the pink one, its so beautiful, but looks like a mess cause the leaves... please help me, what are their name, and how to take care them? i love their colors. thanks alot.
