Suggested Uses:

The Sweet Street™ Linden is an excellent choice of tree, ideally planted in a full sun location, the tree exhibits a narrow canopy making it a great choice for a smaller landscape with width restrictions—Including use as a street tree or as a statement tree near a foundation. The Sweet Street™ Linden presents beautiful glossy green leaves complimented by small, fragrant, yellow flowers. The glossy green color of this Linden tends to persist much longer than other linden varieties.

There are many notable characteristics of the Sweet Street™ Linden, making it a desirable choice for many locations, including the narrow growth habit, sweet smelling flowers, small nutlets, and sweet nectar. You may also recognize this tree by its leaf structure- an asymmetrical base near the petiole; cordate shaped leaves, and acuminate tips with serrated margins – Common in Lindens and elms.

Wildlife Value:

Because of the sweet nectar, which is present in July, the Sweet Street™ Linden is an excellent choice for insect pollinators such as butterflies and bees. Birds often take advantage of the dense canopy and use Lindens for nesting and shelter purposes. The small nutlets are a favorite of small mammals that forage for food before the snow hits in winter. Aphids are a frequent visitor to the tree leaves which are a food source for ladybugs and other insect-consumers. As the leaves fall in winter they will make for a nice layer of shelter for overwintering insects, and as they decompose, they will create a mulch layer to naturally fertilize the surrounding soil.

Maintenance Tips:

After planting into the landscape, the Sweet Street™ Linden will need to be watered to keep the soil moist for the first two years as it establishes. Once established, the maintenance will be minimal, mostly requiring mild pruning as the canopy becomes too dense.

Overall, the Sweet Street™ Linden will not carry many pest/disease problems, making it an excellent choice for a low maintenance tree. The main pests associated with this choice would be Japanese Beetles, which will aggressively feed on the leaves, though this will not cause much physical harm to the tree, it mostly damages the aesthetic value. Though if the tree is small enough and is entirely defoliated, the main feeding source for the tree is removed. To prevent further insect stressors, ensure that the tree is consistently watered in the hot, dry months.

Leaf Lore:

The Sweet Street™ Linden was selected by Darrell Kromm in Reeseville, WI from a native seed source in Dodge County. Fun fact: The flowers can be used to make a nice sweet tea!

A commonly used name for American Linden is Basswood. This stems from bastwood- the tough inner bark, or the bast- is used to make rope and mats. The light wood is used for furniture, crates, boxes, and veneer. The common name “Linden” originates from Carl Linnaeus, the Swedish botanist. The Swedish word for Linden tree is “Lind”.

Companion Plants:

The Sweet Street™ Linden is a great solo statement planting. If planted into the landscape surrounding the tree with Lilacs (Syringia spp) or Serviceberries (Amelanchier spp) will be great companions that will flower earlier to create a season of flowering. Add Witchhazel (Hamamelis spp) with Asters and there will be flowers through the Fall. Other companion plants could be Dogwoods, or Chokeberrys, these will add a hedge-like feel to create some privacy in the area. Small plantings within the canopy might include part-shade perennials such as Astilbe, Hellebore or Ferns.
