A great gift idea for your girlfriend who likes horticulture would be a gardening tool set or a plant care kit. Alternatively, you could also purchase a subscription to a gardening magazine or a membership to her local botanical garden. Another option could be to take her on a weekend trip to a botanical garden or a flower show. Finally, you could also consider buying her a rare or unique plant as a gift.
Or you can get her a star map with the date of your anniversary.
