Plant of the Month

'Spring Snow' Crabapple Malus 'Spring Snow'

Location: Grid X-3 in the north east corner of the Arboretum.

I know that there is no such thing as a 'perfect tree'. But, 'Spring Snow' Crabapple comes pretty close. This is especially true for this particular tree, because it was budded on a newly developed root stock, known as 'Sprout Free' which has virtually eliminated suckering.

'Spring Snow' Crabapple is known for its uniform shape, clean green leaves and pure white flowers. However, the feature that makes it especially popular is that it is reported to be fruitless. I have not seen any fruit on the two trees in the Arboretum and so far there are no suckers on the tree in the picture which was planted in 2013. There have been some suckers on the second tree which is a little further up the hill, planted in 2000.

Like all of the Crabapples, 'Spring Snow' does well in our climate. Because of our dry summers we do not have the problems with various fungal diseases that plague Crabapples in more humid climates, and we have cold enough winters for them to develop flower buds. I haven't paid enough attention to see if the fact that this tree does not set fruit makes it bloom more consistently from year to year. Most apples are known as alternate bearing, where they set a really heavy fruit crop one year, followed by a much lighter crop the next year. Since 'Spring Snow' is fruitless, it should avoid that issue.

Monthly Projects

The big project for this month only took two days, and actually went amazingly smoothly— but, there were lots of potential problems that caused some stress. Two loggers came in and removed about 35 large beetle infested trees from the west end of the Shattuck Arboretum. There were two full logging trucks of logs hauled to a local small mill who will be cutting the longs into lumber and paneling.
