Roses are sometimes recommended for growing alongside hydrangeas, but they typically make a poor pair as roses are sun-loving,

while hydrangeas

prefer shade.

If you still want to pair them, opt for shade-tolerant roses and sun-tolerant hydrangeas. However, it's best

to keep them separately where both plants' needs can be met.

Royal ferns

are difficult to

grow alongside hydrangeas due to their preference for poorly draining soil, contrary to hydrangeas' need for well-draining conditions.

These fast-growing, non-flowering plants thrive in wet soil, typically found near streams or ponds. This makes them an excellent choice

for rain gardens.

The towering oak tree, with its dense canopy and extensive root system, leaves little room for hydrangeas to thrive.

Planting hydrangeas too close to an oak tree's trunk may stunt their growth and adversely impact their health due to the limited space and competition

for resources.

Lavender prefers full sun, dry conditions, and alkaline soil — conditions that

are quite the

opposite of what

hydrangeas require.

While lavender and hydrangeas may look great together, they'll both likely experience better growth when

kept apart.

Asparagus isn't typically grown with hydrangeas, but if you're inclined to experiment with unusual pairings, it's advisable to avoid this one.

Asparagus prefers alkaline soil with a pH above 6, while hydrangeas lean towards acidic soil with a pH of 6.2 or lower, rendering them an unfavorable pairing in the

same soil.
