HT Program generates publicity

Past HTI student, Annie West from North Carolina had news coverage of her HT program. She anticipates more publicity as the program donates plants for 15 community gardens including Friendship Trays which serves 800 meals daily to the elderly and disabled. To date they have planted 5600 plants and are ramping it up for fall crops. See the article at: Click here: Jail North inmates bloom where they are planted for now –

HTI Connections in Costa Rica

In December, the Centro Nacional De Educacion Especial Fernando Centeno Guell, in San Jose, Costa Rica, hosted a two-day seminar on horticultural therapy. Presented by Rebecca Haller, of the Horticultural Therapy Institute, the seminar attracted over 50 professionals from across Costa Rica – representing special education, mental health, and corrections, as well as housing and services for older adults with memory loss/dementia. In addition to lectures and lively discussions, participants were treated to hands-on activities in the school’s innovative gardens. Since 2002, Andrina Escalante, a dedicated teacher at the school, has led efforts to create and use several themed gardens to benefit children with developmental disabilities. They are remarkable and valuable plant-filled spaces, prompting children and staff to connect with nature in the heart of the densely built urban area of San Jose.

This first-ever HT training event was received with great enthusiasm and energy, and prompted the establishment of a “commission” on HT to further communication and work in this field. They represent a devoted, professional, and eager group – who are passionate about the importance of people-plant-nature connections. Thanks to Andrina, Karla and Damaris, and all who helped to make the seminar a success!

Healthcare Design 09


HTI Director, Rebecca Haller, HTM recently attended the Healthcare Design 09, a conference held in Orlando, Florida in November.

The conference gave us all plenty to think about with trends in the design of healthcare facilities. Evidence-based design  was shared and promoted in order to encourage successful outcomes in healthcare facilities. The myriad benefits of views of nature – both real and in art – were described and touted in several sessions and exhibits. Teaming up with Bruce Hendee and Angela Milewski, of BHA Design in Fort Collins, Colorado, we led a round table discussion about horticultural therapy and healing gardens. Discussion focused on therapeutic healthcare gardens that are designed for treatment purposes (HT) and the need for research to build a body of knowledge about effective design.
