11 am Sun/23 July. I enjoyed it so much I opted to upgrade to the $45/yr membership (which gives reciprocal entry benefits to buncha other botanical gardens in the US). The butterfly exhibit portion is worth the extra fee ($8 non member, $6 member). Searching out the Washed Ashore sculptures was a lot of fun, and I could easily find shade whenever I needed it. This garden much bigger than I expected, I ended up getting my 10k steps (4 miles) exploring a good chunk of the gardens. Look forward to coming back and using my complimentary entry benefit.
