All of the climbing hydrangeas have one thing in common:  it takes them a while to establish their roots after they have been planted which means that if you decide to plant evergreen climbing hydrangeas, you probably won’t see much happening the first year after you have planted it. But of course you will have to keep that soil moist and continue watering day in and day out even if you don’t see any changes to the plant.

What climbing hydrangeas including this Evergreen variety have in common with all of its close relatives is that once the plant starts growing, it doesn’t stop. It doesn’t grow particularly quickly but it lives for a very long time and it will eventually cover large areas of your garden making it perfect for covering walls and fences.

The Hydrangea Seemannii

You will typically find white, frothy flowers throughout the summer but if you want your plant to continue growing in terms of length and width, you can remove the flowers as soon as you see them encourage energy two other parts of the plant. It can make quite a bit of difference, especially in those first few years. This unique Evergreen Climbing Hydrangea like any Climbing Hydrangea is really something that you need to add into your home for the long-term. This is something that you want to plant if you are willing to continually clip away flowers for the first four years in exchange for knowing that the few years after that you will get beautiful blossoms in a very large climber sprawled against your wall.

For this hydrangea seemannii, you will need to provide something against which the plant can grow. Most of these plants are placed next to a wall so they can cling to the wall as they get bigger. They are happiest and greenest on walls or fences that don’t get a lot of direct sunlight so be cognizant of this when you are picking the location for your plant.

  1. Hydrangea seemanii are happy in clay soil as long as it’s in shade. It’s essential to water (but don’t soak) the plant daily when you first plant it, until it becomes established. You definitely don’t want the roots to dry out at this stage, but the clay soil should help with this. It might look like nothing is happening in the first year, but it should grow steadily in the following years. Trim any flowers as soon as they appear to aid growth, but only in the first couple of years. Seemanii is far happier in the ground rather than a pot.
