I planted zinnia seed like 1 - 1.5mo ago and now it's quite tall, 10" or so The leaves look rather small. And one is showing flowering.
Is this normal? Is it lacking sun? Because I live in Pacific Northwest.
I never had Zinnias, but the plant in the picture looks like a healthy plant. If a plant doesn't get enough (direct) sunlight it looks skinny and leggy which is here not the case. Usually these leggy plants can't even stand up straight anymore.
On google I found a picture here with more or less the same height and stem thickness. So I think they will be fine!
