The Proven Winners ColorChoice® Cityline® Mars Hydrangea is a very small and compact shrub with very unique flowers. The blooms range from red or pink with lime green edges, to blue and purple with white edges on the pedals. The flower pedals have a variegated look to them. The color is determined by the soil pH. Blue and purple flowers come from acidic soils. Red and pink flowers grow in more alkaline soils. These shrubs perform very well by the ocean, and prefer moist conditions. The plant is also mildew resistant, which helps in rainy areas.

Cityline Mars Hydrangea Care

These bushes do best in well-drained soil. We recommend amending the soil with peat moss or compost. Applying mulch will help retain moisture as well as adding extra winter protection, which may be necessary in colder climates with harsh winter conditions. Pruning Cityline Mars Hydrangea is not necessary, but if you choose to do so, trim immediately after flowering. This shrub blooms on old wood, so pruning in fall or winter will reduce the amount of blooms for the following year. You should also provide extra protection during winter to help keep the flower buds safe from the cold. If you plant this shrub in a garden planter, be sure to either move the plant indoors over the winter, or plant in the ground in the fall. Fertilize in early spring, using slow release fertilizer designed specifically for woody plants, such as roses.

Cityline Mars Hydrangea Spacing

Plant these shrubs 2 to 4 feet apart, center on center. To create a landscape border, plant these a little closer together, around 18 to 24 inches apart, center on center. These do great in containers, but need to be planted in the ground in the fall.

    Stunning hydrangea!

    Posted by Ken on Jun 8th 2021

    This hydrangea is an absolutely beautiful plant with glossy dark green foliage and stunningly gorgeous flowers! It's a very healthy looking plant, and it grows quickly if planted properly. It does best in more shade than sun.

    Great Place to buy...

    Posted by Gary Amistadi on Jun 5th 2021

    Plants arrived in perfect condition. Very healthy. They send emails on care for the plants, and even a follow up watering schedule. I will definitely buy more from Plant Addicts.

    The plants were much smaller than I expected. I probably should have asked about the size before I ordered them

    Plants Looked Great!

    Posted by Heather Trojanowski on Aug 14th 2020

    I got two small hydrangeas and was so happy that they were leafy and green when I opened the box! Got them in the ground right away and made sure to water them. Can't wait to see if these little guys produce flowers next year!

    The virus complicated this purchase by delaying delivery, in addition to small plant growth. Plant Addiicts worked with me through the process and sent excellent quality plants to brave SC Summer heat

    Plant Looked Healthy

    Posted by Judi Haase on May 24th 2019

    I don’t know for sure who to blame, but it appears I have a healthy plant, but FEDEX, through it on the porch upside down in a box clearly marked plant, this side up.
    Plant hopefully will make. Had to be transplanted immediately.
