The Horticulture Section offers online courses in gardening and garden design, botanical illustration and permaculture design.

All our courses feature practical, hands-on activities because we believe learning by doing is key to any successful online horticulture course. These are non-accredited courses for non-matriculated adult learners, which culminate in a certificate of participation (not a degree or certification).  Participants register for enjoyment, to strengthen a skill set, or to inform new directions in their lives.
