What's Blooming at ZBG

April 2010—
Spring is the time when rapid successions of blooming plants produce one of the most colorful seasons of the year.  

Spring Blooming Plants
The Zilker Botanical Garden staff is at it again creating a beautiful display integrating  tropical plants among spring blooming plants for Zilker Garden Festival held in late March.

   Azaleas & Wisteria
In early April, Zilker Botanical Garden azaleas are in full bloom along with Wisteria. The shade of Zilker Botanical Garden and the naturally enriched organic and acidic soil under the oaks provide an excellent microenvironment for azaleas to grow well.

Hardy Orchids
Near the entry to the Zilker Garden Center are hardy orchids (Bletilia spp.) They love shade and organically rich soil and once established, reward us with their blooms.


  Bridal Wreath Spirea
Bridal Wreath Spirea, a deciduous shrub, comes to life with dazzling display of white blooms along its cascading branches. This makes a perfect companion plant for azaleas in the spring garden. 
Bearded Iris
Bearded/Germanic Iris spring into bloom in April, They have benefitted greatly from the colder and wetter winter season and are rewarding us with their dazzling bloom this year.

Lady Banks Rose
The Lady Banks Rose is overwhelming in the quantity of yellow blooms it produces. This very vigorous vine rose needs plenty of space to sprawl. It blooms only in spring.


Texas Mountain Laurel
Texas Mountain Laurel (Sophora secundifolia), not only can be seen from a distance, but detected by its grape juice fragrance. This evergreen is a standout for central Texas and can be grown as a large shrub or small tree, depending on trimming.
  Redbud tree
Our Redbud tree, fondly named “the Dr. Seuss Tree”, shows its uniqueness by producing bloom along it’s trunk as well as branches. The Redbud is the only plant in North America that has this blooming characteristic known as cauliflory, common to many tropical plants.
