Planting Tips for Zinnia grandiflora
These plants won’t begin to grow until warm summer weather has arrived. The long thin string-like roots are brittle and do not like to be disturbed when transplanting, so don’t scratch out the root ball. When transplanting while it is still cold, water the plant thoroughly only once. Continued watering during cold weather will rot the roots. Don’t start to water regularly until the weather warms and the plants begin to grow.

Great on southern exposure

About Me Avid Gardener
Comments about High Country Gardens Zinnia grandiflora:
I planted a few on the southern side of my house. It's hot and sunny, and under the eaves, so it doesn't get much rain. In the summer I water them with the hose every week or two if it hasn't rained. I planted about 5 plants a few years ago, and they've spread to fill the space. Very satisfied with this hardy and attractive plant, especially for the difficult southern exposure.
Bottom Line Yes, I would recommend this to a friend

I had high hopes for this plant but it arrived dormant and never grew. Perhaps it will show up next spring?

Not happy in Illinois
from Knoxville, IL
Unfortunately, this Zinnia did not make it out of the gate. I was perplexed why it did not survive the initial season of planting. We did have a wet spring and early summer that year, so possibly that was the problem.
