disappointed these came in great shape took a while to grow ,but they were not the size of a dinner plate.so i waited to see this year if they would get bigger but to my saddness they did not regrow at all kind a waste of money . 05-16-15
LOVE THEM Ordered 8 bulbs last year and planted them in front of my front porch. Had fantastic remarks from neighbors and strangers. They bloomed the size of saucers last year, hope they get to expected plate size this year. Plan to plant them climbing 2 light posts this year. Only problem is having to dig them up every year. 05-06-15
Nothing I will wait a little longer but it looks as though the squirrels aren't even interested in digging them up so there is nothing for the deer to be bothered with. I am done with flowers on QVC...... 05-05-15
Dahlias dissapointing This is the second order of dahlias, the first just withered up and never grew. These I received and planted in pots. A lot were very withered, and some were wet and rotting upon receiving them. I threw the wet, mushy ones away, and planted the rest. Will wait and see. I have planted dahlias and stored them for years and don't know why these are the way they are. 05-02-15
Regret I ordered these last year and only three of them came up. They were gangly and unless you tie them up they don't look very pretty. You also only have a year to ask for a replacement which isn't right because I got them April 17 and now a year later they are just starting to come up but only two of them so it is past the year for me to be able to get the other two replaced. 04-29-15
Beautiful I purchased these last year. 3 of the four grew. I called Roberta's and they said they would send out a replacement. One did not come until a few days ago- which makes sense due to growing seasons. I only gave this 4 stars because they were not as over the top as the plants shown on QVC. Mine did well but they were not bigger than any other large Dahlia I have seen. I will try a different fertilizer this year and see if that helps. 04-27-15
Disappointed I was so excited to get these, but when I opened the box the bulbs were not even close to the size on the shown on the presentation. The Avignon bulb only had a small middle root and the two small roots on the side were dried and hanging buy a thread. The Grand Finale bulb was dried and had black spots on it. I planted them anyway, but do not have great expectations. 04-23-15
Terrible I followed the directions and planted these just as they told me to do and my flowers were small total plant was maybe 2 foot tall so disappointed would not order again way too much money for what you get 04-23-15
DISAPPOINTMENT, awaiting replacement I bought these last year they did not grow, I called Robertas for a replacement and I am waiting for them. Hopefully they will not disappoint again this year. If they do Robertas will not replace again. I will inform. 04-22-15
1 Bloom Just the worst, all I got was long stems that broke in a hard rain . Salvaged 1 Bloom purple lasted 2 days crumbled and died. My dinner plates were really bad just crusted and died they were in a diffrent bed. My Hedranges(?) Are 12 years old and last year was the only year with few blooms. Can't waste any more $$$. Sad sad sad 04-14-15
GIGANTIC BLOOMS I have ordered the Over the Top Dahlia's 4 times. Sometimes they grow huge and sometimes nothing grows, but the Bodacious. For some reason the Bodacious always grows with tons of blooms that are huge. People stop while walking or driving by just to ask me what they are and tell me how BEAUTIFUL they are. I dig them up every year and give them away to my friends and neighbors and they LOVE them. I plant these in my front yard on the fence line because they MUST BE STAKED OR TIED TO THE FENCE. The stems are hollow stalks and grow 4 ft tall and 4 ft wide like a shrub. Strong winds and hard rain will break these. 04-12-15
These Plants Are Amazing. I bought these last year. Did a lot of traveling over the fall and winter and did not get them out if the ground like I was suppose to. They are coming back up this year. I am in Tennessee and we had a bad period of ice and snow. I thought for sure they would survive. I was so excited to see the new growth. Not sure why there are bad ratings on these flowers. They were everything they advertised. I hope to get some pictures this year and add the Roberta's flower food. Customer service at Roberta's is also excellent and very helpful. Very excited about this years new growth and the strength of these plants. 04-04-15
