For more than 40 years the oldest botanical garden in the Netherlands has been able to rely on the support of Friends. This place, a green oasis in the historic centre of Leiden can continue to exist thanks to the support of Friends and donors. It enables the Hortus to present its unique collection to the public and to both share its passion for plants and its recognition of their importance.

All donations are welcome. You can become a Friend of the Hortus with a donation of €27.50 or more per calendar year. As a Friend you not only support the Hortus but also receive something in return. At the bottom of this page is a list of the different types of Friendship with associated benefits, for you to make a choice. There are, for instance, Friendships which give free entry to the Hortus for 1 or 2 people. There are Friendships involving supporting the Hortus with a larger sum (Clusius Friend or Adopter) and there is a special Young Friendship. 

Where does your contribution go? 

However small or large it is, we ensure that your donation will always be used to benefit the preservation of the Hortus. This means that your contribution could be used for:

  • Maintenance, renovation, and improvement of the garden and glasshouses
  • Increasing its attraction for visitors
  • Activities and events to increase Hortus brand awareness
  • Accessibility and education
  • Other activities related to the preservation of the Hortus

On the Friends pages you can find more specific clarification on how your contribution will benefit the Hortus.

How will we communicate with you?

Messages concerning your Friendship will be sent digitally as often as possible. This is not just better for the environment but also saves money. Is digital communication not an option for you? Not a problem! We will inform you by post.
