Know before you buy
The Sister Theresa Hydrangea is sensitive to soil pH. In more acidic soil, you will typically see blue-toned edges on the petals, while neutral or alkaline soil will result in more consistent pink hues.
This is a fast-growing shrub that needs consistent moisture to thrive, especially during the heat of summer. You should plan to prune it immediately after the flowering season ends to encourage healthy growth for the following year.
Yes, it is well-suited for container gardening. Just ensure the pot is large enough to accommodate its eventual 5-foot spread and that you provide regular water, as containers dry out faster than garden beds.
Yes, the Sister Theresa Hydrangea is tolerant of urban pollution, making it a reliable choice for city gardens or areas near busy streets.
No, this variety is not considered deer resistant. If you live in an area with high deer activity, you may need to use protective netting or deterrents to keep them from grazing on the foliage and blooms.
It performs best in full sun to partial shade. If you live in a region with very intense summer heat, providing some afternoon shade will help prevent the foliage from wilting.
