Question about Dahlias
« on: June 19, 2009, 08:38:46 AM »
Do all dahlias, irrespective of whether they were grown bulb or seed, eventually form bulbs? I have a packet of dahlia seed (Unwin Hybrids, I think) to sow and was wondering if they would form bulbs?

I have no idea Kareen, but I'm glad to see a post here! It's been so quiet the last while, I thought there was something wrong with my internet connection.

Why do you sound so guilty, Kareen? What have you and Michael been up to?

I think everyone's in hibernation at the moment.......

It would have to have been the internet's fault, because I never ever do anything wrong........

I'd sow leonotis anytime Kareen, but the winters are pretty mild here. Don't worry about wasting seed, there's more where that came from! Leonotis is an ultra tough pioneer plant, one of my favourites. Transplants easily, sunbird magnet, medicinal use, pretty flowers.

Yep, Michael and I are the forums angels, aren't we Michael?   ::)

Thanks Michael, I'll give some of the Leonotis in seed trays a bash soon.  Winters here can be harsh - min temps around 5, sometimes -3, and can have black frosts too. I absolutely love the white leonotis, one of the few white flowers I'm fond of, and want to put in a mixture of the yellow, white and orange as a backdrop (can't think of the right word now) for my iris bed.

I just needed to revive this thread again to pick Abby's brain.  I planted some of my Dahlia seed yesterday, and the packet says that they are annual, therefore, to my way of thinking, they will not form bulbs  ???  What is your thoughts about this Abby?  Do you think they will form bulbs?

 :mmm: I think the distinction you should look at is between plants and seeds.

Annual seed is planted and will flower in a single season

Biennial seed such as Foxglove are planted one year will not flower until the following year

Perennial seed like Hippeastrum or Clivia will take a number of years to bloom

Plants from any of these seed types may or may not form bulbs.

As to whether they will make good vase specimens will depend on the variety of Dahlia that you plant,
some dwarf types have too short a stem for a normal vase type of display.

Thanks Abby, I think I understand now...  ::)  I'll have to try look for some perennial dahlia seed in the future

 ??? I think your Dahlia seed is annual and will form bulbs which will flower for you this and many years to come unless one of the moles eats them.

You can lift and subdivide these bulbs in winter and make many more plants and also you can sow your own seed after crossing them with different pollen and make your own unique colours.

With these annual dahlias,they do grow tubers but they are tiny and unlike the larger more decorative ones have massive tubers therefore large food reserves for the plants and then can be stored untill you plant them again, the annual are simply to small to save over here so we bin them in the winter,and thats why they get labelled annual even though they are perrenial.

Thanks Abby, fortunately, I don't have a mole problem, I have a Jack Russell and a German Shorthaired Pointer cross - they are both pretty good hunters.  They kill a lot of rats.  Thanks Davy, good to know that the dahlias will set tubers, I might just be lucky enough to be able to have them grow to a reasonable size - I could try feeding them just before they go dormant.  That's the joy of gardening - trial and error, hit and miss  :P
