Sybil B. Harrington Cactus and Succulent Galleries Desert Botanical Garden

Phoenix, Arizona
Client: Desert Botanical Garden


Oasis Design Group was the landscape architect for the landscape renovation and collection displays for the Cactus and Succulent Galleries. Oasis’ innovative design enabled the two Galleries to be unlike anything seen in the southwest and at any other botanical institution of its kind. The development of the Galleries’ structures enables more tender species of plants to be displayed in a unique and condensed area protected from the hot Arizona climate.

Firm Accomplishments

  • Designed the landscape collection displays of the two Galleries, which included the development of walkways, earth sculpting, rockwork, and overall planting design in both in scientific and aesthetic terms that included the strict display criteria of various cacti and succulent plant collections.
  • Focused on the beautiful appearance/aesthetic appeal of the plants and grouped them en masse-many plants of the same kind grouped together and combined them in ways that have not been typically done with cactus and succulent plants.
  • Developed planting boundaries for various types of plant materials based on sun/shade computer modeling studies.
  • Arranged plantings by contrasting form, texture, and foliage color in order to achieve maximum impact. The arrangement does not replicate the planting communities as they appear in nature but rather it emphasizes the unique characteristics of each plant.
  • Collaborated with nationally acclaimed southwest based landscape architect Steve Martino, FASLA, who designed the shade structures.
