Great Plant Pick: Larix kaempferi ‘Diana,’ contorted Japanese larch

Published 1:30 am Friday, July 31, 2020

What: Each delicate needle and branch on Larix kaempferi “Diana” twists and turns like a corkscrew. The twirling blue-green needles are irresistibly soft and very touchable. In the fall, they turn a golden yellow and drop from the tree so that the distinctive form is in full display. “Diana” will grow as an upright pyramidal tree, but can be easily trained as a smaller, striking specimen by careful pruning.

Where: The contorted Japanese larch grows best in rich well-drained soil, but will tolerate sand and clay with adequate drainage. Plant it in a location with full sun to light or open shade.

Size: This unique deciduous tree will grow to 20 feet tall and 7 feet wide when mature.

Care: Provide “Diana” with occasional watering during prolonged dry weather. The unusual habit needs no pruning, but it can easily be kept smaller in size with yearly light pruning in winter.
