We were delighted to be featured in a two page spread in the November 15th edition of The Press Democrat. The article focused on a Petaluma residence with a dying lawn which badly needed a makeover. The homeowners asked us to design a waterwise garden which would be more coherent overall and provide interesting foliage and year-round color. The result is a design that showcases a variety of Mediterranean plants which bring a myriad of textures and soothing colors to the landscape.

TESTIMONIALS

I came home today to find a group of women stopped in front of the house, admiring the garden!! They loved the plants and the metal and the walkways and the way it all worked with the design of the house. It made my day…The garden is a gift that I appreciate daily—and now I’m learning that the neighbors do as well. Thank you!

Nina turned a small depressing front yard into a vibrant, colorful garden with multiple uses: a patio and seating area for adults, a playground for children, a dry habitat for butterflies, birds and bees. This was no small feat. Her knowledge of plants (water attractors) is extensive. She knows and has worked with local contractors, and is knowledgable about how and when to cut costs. Her insight into how gardens are used and constructed is deep and wide. She was onsite with contractors, making sure they understood what was needed. She has imaginative and wonderful ideas, and a lot of useful experience making gardens places of beauty and life. I recommend her wholeheartedly to anyone wanting to improve their garden and life.

I often think of you when I am in my front garden and it is unfolding over the years in such a lovely way. I still love the choices you made for us!

Nina was great to work with…she is very personable and is an excellent listener who was able to translate what we wanted into the final design of our garden project.  What we enjoyed most (besides the final result!) was the way she guided us throughout the project from the initial design to the last plantings in a way that leveraged her expertise but always kept our likes and needs in mind. She even helped us find a contractor that was right for our budget and we were very happy with the end result!

We love our garden and it receives so many compliments. We also enjoy how wild animals, birds, cats, and dogs drink from the stone water feature. Plus, we have very cute twin toddler neighbors who love to run around in there. I think your work has brought pleasure to many!!

Mullein Designs beautifully provided much needed integration between two Victorian buildings via landscaping. They introduced to Robert Cruikshank who capably installed the masonry and the planting services. Mullein and Cruikshank worked together in seamless fashion. They were a pleasure to deal with on many different levels. The garden, as designed, is warm, inviting and charming. We are all thrilled.
