Sucker #2. Long, leafy shoots. Again, no sign of fruit or flowers. Just lots of shoot.
And a close-up of a Sucker #2's "trunk," which is just a long shoot coming up from the base. Get a load of those spines!
Ahhh, this is nice to see. My second grapefruit -- don't yet know if it will be yellow or red flesh. But please note the thick trunk, evidence of fruit and outward (not just upward) growth.
