Here's the note I have on the ivy in the database from the book 'The Beekeepers Garden'
Important source of nectar and pollen in late autumn.
Birds love the berries and nesting places.
The young ivy does not flower; it is the older shoots that are of interest to honey bees. May take 15 to 20 years to mature enough to flower unless you can root a mature shoot from an exisiting plant
Thanks Robin I'm going to blame all this fun work on you LOL
