Answer:
Step-by-step explanation:
Up here in Northern Canada, we call that a May Green. It is a very special green, much purer in appearance that the darker greens of mid summer.
But the color gold is not a color in this quotation. It is the metal gold. It means that when you see the green come up, it shows that the plants have germinated and the crops are beginning to grow. If the plants are dense it means they've had the right amount of rain and sunshine and the crop will be a "bumper" {large} crop.
It means that those first green shoots are worth a lot. Or it could mean it's nice to see them. It depends on the circumstances and the speaker.
