BYM those trees are soooo gorgeous. They remind me of wisteria. It must be incredible to see these in 'real life'. I love this time of year, with all the blossom. Even the hawthorn is truly beautiful. My Mum gave me a cutting in summer 2018 and 2019 from her tree. It's called Abutilon. They grow huge in a short time, last years grew from being an 8 inches tall cutting, in a plant pot, which I immediately put in the border, it is now over 5 foot high. The other planted in 2018 is 9 foot. That one was moved from a shady area, but somehow survived the ordeal. I love them so much that I googled the type and found there are many varities with different blossom, so bought 5 in different colours. One already has an orange blossom.
It's been incredible weather for Spring, the best I have known for many years.
