Gardeners' Notes:

Oct. 23, 2013, zone 5b, Columbus, Ohio. Just purchased this tree last night at Home Depot. It was in beautiful shape and can't wait to get it in the ground. Beautiful dark maroon-brown bark, but is a weeping form crabapple tree.
The shape kind of reminds me of weeping snow fountain cherry. Can't wait to see the flowers in spring 2014, Lord willing.

Our wild and free-spirited Louisa was purchased at the end of the season in 2009 with a huge gash up her side and a break on one of her top branches. She has healed herself, grown up and out beautifully. I did not water her much this summer of extreme drought, and she shows no wear or stress.
She sprouts growth from her roots, which I trim about every month. I have not pruned her at all.
She has consistently flowered abundantly, smells divine, produces gorgeous profuse golden/pink blush apples that the birds and squirrels love, and is a work of art in the summer and winter.
One must have an appreciation for a graceful unusual tree (her branches turn up at the ends) that expresses unbridled joy!
She is that!

Mine took a few years to establish itself, but now it displays substantial growth year to year and lots of fruiting/blooming spurs, including some that burst out with flower buds from last year's shoots, as well as the expected buds on spurs on the growth from the year before last. One long branch even has a bud cluster at the tip the way my wild Malus ioensis does The biggest surprises so far have been leaves that sometimes color up some and persist into late fall, and healthy growth that is more horizontal than weeping in the way a weeping willow would grow.

Does anyone have experience with growing these guys into a pergola or large scale trellis?
