Some Agaves can live for hundreds of years and take a long time to flower.
The ethylene released by old banana skins may encourage flowering. Similarly, smoke can trigger flowering too.

Suggestions include Daphne Burkwoodii 'Somerset Gold edge'; Desfontainia Spinosa variegata; Drimys lanceolata or 'Mountain pepper'
Q. What has happened very beloved, old apple tree?
It is suffering from leaf miner, scab and powdery mildew. Old cooking apple trees, such as these need extra potash to help fight off disease. Try spreading woodash under the canopy.

Q. Is it true you should not pull rhubarb sticks from July onwards, due to a toxin rising in the fruit?
This is false.
