| Origin | US |
Ulmus parvifolia 'DavesStraightUp' (selling name DannaSpire) is a Chinese Elm cultivar notable for its narrow profile. It was cloned by Dave Dannaher of Dannaher Nursery, Galena, Ohio, from a seedling selected there in 2001, sown from a non-cultivar Lacebark elm, and first propagated in 2010.[1] After evaluation for consistency in habit, the variety was patented and released in 2020 (USPP31914),[2] being introduced by Plantipp and grown under licence with Concept Plants.[1][3]
Description
DannaSpire has a columnar habit, with a dominant central leader. It broadens a little with age[1] but retains a narrower form than the similar Lacebark elm cultivar, Everclear.[2] It has a "moderate to slow growth" rate,[4] reaching about 20 to 25 ft by 4 to 5 ft in fifteen years, and growing to about 30 ft.[4][5] With age the bark exfoliates, the curling strips revealing patches of orange-tan, grey and white. Leaves are about 1.5 in by 0.75 in,[5][6] smaller than the type, dark green in summer, a "lasting" yellow and orange-yellow in fall.[6] The flowers occasionally produce small seeds.[5] Hardy to USDA Zones 5 to 8.[4][1]
Pests and diseases
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, resistant to elm phloem necrosis (elm yellows), and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[7]
Cultivation
With its fastigiate form, DannaSpire is recommended for street and urban planting.[1] It has been planted in one US arboretum (2025) (see 'Accessions').
