Thanks - another great webcast. For those of us living too far away to take advantage of other ELA offerings, your webinars are eagerly awaited. I teach classes at the NC Arboretum, and always tell my students about them.

Thank you Penny for making this delightful series available to members of the GCFM. [A Walk in the Garden webinars] have been one of my favorite hours each week this springtime. The speakers have been top notch subject experts who have excellent teaching skills to boot. Their photo presentations have been beautiful and informative. All around an excellent series!

Speakers were very good, but meeting landscapers at the talks & in the lobby was best.

I thoroughly enjoy being a member of ELA. In fact, I get the most out of my membership from your organization than from any other professional organization I belong to. Your educational opportunities are fantastic, I have enjoyed every webinar I've ever attended, and your newsletter is always informative and helps me do my work. Thank you!

I am really enjoying all the webinars that the Ecological Landscape Alliance is offering. Thank you so much for organizing them and making them available for FREE! I spread the news about them on my Constant Contact page for the NJ Native Plant Society. 

Susan H.

I salute you on the excellent conference today at BBG! It's cheering and edifying for my staff and me to be among so many people, old friends and new, who value horticulture and ecology.

I want to thank you and ELA for having such a wonderful speaker [Heather Holm] talk about our native bees and plant partners. It was fantastic. Great photos. 

Virginia K.

Just want to say again how very much I appreciate the “Walk in the Garden” series. The quality of your programs is tops! A “Walk in the Garden” is so much more than a series of slideshows. It is a celebration of how all life is connected. It is great to have this positive reminder amidst the scarier reminders!

K.R. Watkins

I wanted to thank you for an excellent Walk in the Garden series. The webinars were all-around professional, fact-filled, and pertinent presentations. I've learned a lot and am inspired to implement some changes!

Margaret R.

Thank you for via webinar - it really helps to save the professional development budget & travel time from my job. I find these information sessions very interesting, inspiring and informative.

Thanks for providing the great professional society that I have been long searching for.... I am definitely a better, more informed practitioner for it.

Thank you for a full day’s worth of insightful material! Thank you for organizing this great event every year.
