As you get two masks of color
s, then use cv2.bitwise_or
to get the final mask.
import cv2
## Read
img = cv2.imread("sunflower.jpg")
## convert to hsv
hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
## mask of green (36,0,0) ~ (70, 255,255)
mask1 = cv2.inRange(hsv, (36, 0, 0), (70, 255,255))
## mask o yellow (15,0,0) ~ (36, 255, 255)
mask2 = cv2.inRange(hsv, (15,0,0), (36, 255, 255))
## final mask and masked
mask = cv2.bitwise_or(mask1, mask2)
target = cv2.bitwise_and(img,img, mask=mask)
cv2.imwrite("target.png", target)

BTW, to get more accurate range, here is a refer map in my related answer:
