QuestionWhat hibiscus can be panted in Michigan? Thank you
AnswerHello George,
You have written about one of my favorite plants! Hibiscus Moscheutos, hardy hibiscus, will be very successful at your location if you are zone five or above. It is completely hardy in zone 5a, where I grew Lord and Lady Baltimore, which are red and pink, respectively. Both are gorgeous.
It grows 4 to 5 feet high and 2 to 3 feet wide, and is actually a small shrub. It blooms from July to September. It is extremely low maintenance, although it dislikes dry soil. I used to water mine, and deadhead the spent flowers. Full sun is best, and a location with some protection from wind will help to preserve the gorgeous flowers.
At the end of the season, in late autumn, cut it back to about 4-5 inches from the ground. It will be slow to emerge in the spring (don't mistake it for death and remove it!) but then the growth is very rapid. Once it appears give it fertilizer. Regular fertilizer produces the best flowers.
One caveat - Japanese beetles like this plant! But it didn't stop me from growing both of these. It is highly recommended by botanic gardens.
Is this helpful? If it is not, and you need more information, please don't hesitate to write again.
