I see. Well I don't know what happened but it's got progressively worse. I suggest forget AA for now, its just for polishing finished parts usually inside a sprite. We need to work on the form.
Look at this photo:
Beautiful. Why? Let's observe what we see. The emphasis is on the green shoots.. the fresh new life which is being born. The light is hitting the green shoots and providing some subsurface scattering, moreso near the bulb. The effect being that the green shoots very slightly emit light compared with the bulb (the light actually bounces around inside and then out so it only appears that way, whereas light is largely absorbed when it hits the bulb). Some of the top of the bulbs are a little translucent so you can actually see the shoots inside. The colour is distinctly light yellowish-brown with tints of green underneath, not red.
The shoots that come out don't curl at all, they go straight up and only bend outwards up to a 15 degree angle in a radial fan with two of the shoots remaining centralised. Effectively they form wrapped around each other and spread and straighten as they extend vertically. They are approximately 4 shoots coming from each bulb. The length of each shoot is roughly the same as its surrounding shoots but with variations of up to 10%. Each shoot is pointed at the tip only. The colour of the shoots graduate fairly linearly from the luminescent lime green at their roots to a more olive green near the top, which has more red and less green in the hue, and therefore also a reduction in value since green holds most of the brightness in light (eg. our monitors). However about half the shoots (randomly) then transition back to green at the tip but don't reach all the way back to the bright green of their roots. The point where the shoots sprout from on the tip of the bulb is essentially a ring of darker brown which looks burst, and this dark value contrasts sharply against the bright green shoots erupting from the bulb.
I'll leave the bulb mostly as an exercise for you to observe, probably from other photographs or better - in the palm of your own hand.
