Rated 3 out of 5 by from Kind of dissapointed Bought 2 sets so a total of 6 bulbs our of the 6 bulbs only 4 bulbs sprouted. Right now one is very bushy while the other 3 are somewhat small.

Rated 3 out of 5 by from Not All Took Off Planted 3 bulbs. One was puny. No growth from the third bulb while the other 2 are ok. Going to call them. Should have stayed with Lowe’s plants for half the price.

Rated 2 out of 5 by from Trying again Bought these last year. Only one grew but that one was puny. One flower about 6” across. Then it died off. Going to give it another try this year as they look so pretty on demonstration.
