"Happy Sap", "Healthy Honeydew", "Thank You Trickles", etc...
Just some of the names used to identify these beads of nectar produced by the plant as it announces to pollinators that it is getting ready to bloom.
These are sure signs that the plant is healthy and the flower buds are in good shape. Keep them away from ants though, as they tend to flock to the plant to harvest these droplets.
Some folks here are known to lick them (literally). I personally would not though, as some can be hallucinogenic ~~~groovy!!!~~~
