Deciduous Tree Of The Day

 
Acer negundo 'Flamingo'
Boxelder, Ash Leafed Maple

Type Tree, woody plant
Hardy range 5A to 8A
Height 25' to 35' / 7.60m to 10.60m
Spread 25' to 35' / 7.60m to 10.60m
Growth rate Average
Form Rounded
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color White
Bloom Time Spring

Environment This plant tolerates drought, flooding and some salt.
This plant will grow in very dry to wet or submerged soil.
Suitable soil is well-drained/loamy, sandy or clay.
The pH preference is an acidic to alkaline (less than 6.8 to more than 7.7) soil.


Leaf Color Green, silvery and variegated
Fall Color Orange and yellow

This plant has attractive foliage and attractive fall colors.

Culture Notes The tree is sometimes listed in catalogs as Ash-Leafed Maple and the numerous, attractive seeds of the species are very popular with squirrels. But this cultivar produces no seeds because it is a male clone.
A nice plant for naturalized areas, particularly if the soil is wet, or the pH is alkaline. It is probably best used in these areas to help stabilize stream beds and colonize reclaimed land. The species is usually not recommended as a street tree due to its weak structure but may have a place in the landscape. This cultivar may have a place along streets where a small to medium sized tree is needed for tough situations. Growth rate is much slower than the species which makes the branches less susceptible to breakage, and unlike the species they are no seeds to litter the ground.
Maintain adequate mulch area Clear all turf away from beneath the branches and mulch to the drip line, especially on young trees, to reduce competition with turf and weeds. This will allow roots to become well established and keep plants healthier. Prune the tree so trunks and branches will not rub each other. Remove some secondary branches on main branches with included bark. This reduces the likelihood of the main branch splitting from the tree later when it has grown to become an important part of the landscape. Locate the tree properly, taking into account the ultimate size, since the tree looks best if it is not pruned to control size. The tree can enhance any landscape with its delightful spring flush of foliage. It can be the centerpiece of your landscape if properly located.
