Though this article is 2 years old, I’m hoping someone may respond to my query regarding Cotinus? As a florist, I grow purple Smoke Bush to harvest its foliage. I am aware the plant can be severely cut back to encourage new growth. What is the latest (in the growing season) pruning can occur to encourage this (“water-sprout”) growth without harming the plant? As an aside: I enjoy walking the grounds at Scott Arboretum learning new plant materials… After viewing your Spigelia over 8 years ago (?), I purchased some and it has performed well at our home. I am also excited about my newly planted Paulownia, which I will also cut back in a similar fashion as my Cotinus, to enjoy it’s uber large leaves and discourage flowering/re-seeding in my garden. The Arboretum is a fountain of knowledge and ideas! Cheers!

Can you tell me something about how long it takes before Pinus bungeana develops its beautifull bark? I read different things about it, ranging from 10 to 25 years. Also, is the specimen on the photo a seedling or grafted? Someone told me that when you graft Pinus bungeana on Pinus armandii it will grow much quicker and develop its characteristic bark at an much earlier age. Thanks in advance for answering these questions. Kind regards fromTheo/The Netherlands
