HPSO Programs
Volunteer-led. Plant-inspired. Rooted in community.
There’s something special about being invited in—behind the garden gate, into a nursery after hours, or onto a trip you’ll remember for a lifetime. HPSO programs bring gardeners together through unforgettable experiences, from local garden visits and rare plant sales to inspiring talks, a beautiful quarterly magazine, exclusive nursery events, and bucket-list travel. Join us to discover the gardens, people, and places that make gardening feel endlessly new.
