Blueberry Smoothie™ Rose of Sharon Althea Tree

Blueberry Smoothie™ is a deciduous Rose of Sharon trained as a small ornamental tree. Its rounded canopy carries large, ruffled, double violet-blue flowers from midsummer into fall, providing a vertical accent for an entry, border, or focal point. ## Features The [tree-form nursery profile](https://www.tree-land.com/products/blueberry-smoothie-althea-tree-form) identifies the plant as Hibiscus syriacus ‘DS01BS’, gives mature dimensions of 8–10 feet tall by 6–8 feet wide, and lists USDA Zones 5–9. The [Royal Horticultural Society record](https://www.rhs.org.uk/plants/539010/hibiscus-syriacus-blueberry-smoothie-ds01bs/details) confirms the DS01BS selection name. Plant patent PP26662 was issued on April 26, 2016, according to the [patent record](https://patents.justia.com/patent/PP26662). ## Growing Set the tree form in a sunny site with room for its canopy. Water consistently while establishing and during extended dry weather; maintain a mulch ring without piling mulch against the trunk. Its deciduous habit means it will be bare in winter. ## Maintenance Inspect the canopy for crossing or damaged branches and prune selectively to preserve its trained tree outline. Keep the base clear of competing weeds and refresh mulch as it breaks down.
