Plants for Rooftop Gardens (Growing on a Windy Site)

Please share this with friends and family

In this article, plants there are suitable to be grown in rooftop gardens will be discussed. Rooftop gardens tend to get a lot of sunshine but are also exposed to extremely windy conditions. In order to do well under these conditions, you need plants that are happy basking in the sun, but also windproof, and can be grown in containers.  This is not an easy task to meet but with the correct selection, it is possible to have plants throughout the year.

Most rooftop gardens are container gardens by nature, as this makes it easier to move around. Remember most roofs have weight restrictions, so you need to opt for lighter containers made from galvanized (rust proof) metal or UV protected plastic. You can also consider wooden troughs or half-barrels for a more rustic design.

Roof Top Garden
Roof Top Gardens can look stunning.

Sun and wind can be damaging to plants, as the compost that they are in, will dry quickly, especially in the height of summer. You will need to use an automatic watering system or watering spikes.

Despite these limitations, you have plenty of shrubs and small trees to give height and shade to your container garden. Roses, perennials, and annuals will give colour to romantic scheme, and phormiums and grasses to give leaves to complement modern designs.

You will also need to use more hardy plants in order to avoid frost damage, which will be prevalent in winter in rooftop container gardens. The following plants make ideal specimens in rooftop gardens, and will thrive:

  1. Wow, so many options to choose from.I didn’t think about wind being a factor in the roof top situation but that makes sense. Of the options you listed, I guess I would be partial to the flowers that have colorful blossoms. The Pyrethrum, Cobweb Houseleek, Stonecrop, Cape Daisy, Downy Clematis, and the Dyer’s Chamomile would be my preferences.

    1. Hi Lee

      Yes it is very surprising what will grow on rooftop gardens and wind is one important factor, which must be taken into consideration before making any selection. Your choices are very beautiful.

      Kind Regards


  2. Wow, this is so interesting. thanks for sharing your passion.

    I am really impressed of the number of plants there are suitable to be grown in rooftop gardens.  I am from Belgium and it isn’t a habit there.  So happy that I discovered your site.

    My favorites are the CALAMAGROSTIS x ACUTIFLORA (Feather Reed Grass) who moves with the wind ;o)

    thanks a lot


    1. Thanks Francoise

      Grasses always add an extra dimension to any container garden but especially in rooftop gardens. I am glad you enjoyed the article.

      Kind regards


  3. Thanks for the great article… Your photos of the plants are beautiful.  I live in the suburbs of Indianapolis, Indiana.  I chuckled for a second at a few of the pictures.  If I see that around in my area, it is usually just plants or trees growing out of peoples gutters. 😂 I would love to have a residence that allowed for roof seating and gardens.  That would be fun!

    1. Thanks Brian

      It is amazing what will grow when you least expect them  to grow. I really appreciate your comments and hope you get a garden one day and use the advice given in this article.

      Kind regards


  4. I am on the last floor of a smaller communal building and I have the task to pick a plants that would  be on our rooftop. That is how I bumped into your article Antonio. 

    You really gave some amazing choices. I do not know what to choose. I will probably go for a combination of Downy Clematis, Mexican Fleabane and Autumn Sage. Those would make the perfect color combination I think.


    1. Hi Strahinja

      Thank you for those kind words and really think your choices of plants to use are very appropriate.

      Kind Regards
