When first opening, the smell is sweet and pleasant to the human, but begin to smell like rotting flesh (carrion).

    Horticultural Information: 

      • Light Preference: Full Sun
      • Light Tolerances: Semi-Sun
      • Soil Preferences: Loam, Dry (Mesic), Dry (Xeric), Well-Drained
      • Tolerances:  Moderate Winds, Drought
      • Water Requirements: Grows quicker with more water, but does not appreciate standing water or very tropical climates. Native to the sub-tropical sub-Saharan scrub land, ergo water accordingly.
      • Notes on Maintenance: A marvelous tree. The iconic silhouette of the baobab represents the African savanna  and the wildlife within. Does not enjoy abundant water, especially if planted in an area that gets standing water. Fruits and flowers are relatively large and can cause a nuisance in transit-ways. Baobabs are understood to be the longest living angiosperms easily living over 1,000 years. (The understood live-time is about 1,500 years) Traders brought the Baobab with them and planted them in villages. The trees often would outlive the village. Important to note that these are pachycauls, so their trunks get large and girthy. Plan infrastructure accordingly. The UH Manoa Art and Art History Department Building was designed around the existing Baobob.
