Know before you buy
The flower color is directly influenced by soil pH. You can encourage deeper blue tones by maintaining acidic soil, while more alkaline soil will shift the blooms toward pinker hues.
No, this variety prefers partial shade. Too much direct afternoon sun can scorch the foliage, so choose a spot that receives morning light and protection during the hottest part of the day.
Yes, the Grammy's Hydrangea is container-friendly. Given its 15-gallon size, it will thrive in a large pot as long as you ensure the container has proper drainage and consistent moisture.
Semi-evergreen means the plant will retain its leaves for most of the year in milder climates. Depending on the severity of your winter, it may drop some or all of its foliage before regrowing in the spring.
The Grammy's Hydrangea features a mounding growth habit with a moderate growth rate. You should provide enough space for it to spread comfortably, keeping in mind its mature size as it fills out its designated garden bed or container.
