Mann Leiser Memorial Greenhouse
If you want a guarantee of warmth and comfort with all the cozy plant vibes you can get, this place is the best. Tons of diversity and some beautiful, moody spaces. There's 2 downsides: It's not the most private (it's become a popular place for parents to bring kids), and it closes at 3:30 on weekdays / 3:00 on weekends. Small parking lot, outhouse bathroom on site.
