I have grown coleus from seed 2 times. The first time they grew o.k. so I thought the second time they would to. What I would like to know is, these new ones i grew all start out with huge leaves, i measured one at 8". However when I pinched it to make it branch it came back with the top changing to another color and also smaller leaves. Is this normal? The first picture is one changing and the second picture is when I pinched off the top of one and it is still growing with the new color. Any advice would be appreciated.
