Do perennial seeds grow really quickly and easily?

I am finding out that perennials , many come in seeds, are not expensive at all.


My question is this: by throwing out seeds are they very good and last a long time?


I mean just as good as if you bought them in pots at the nursery? (which I am sure are more expensive)





I am use to zinnia seeds and how they grow really tall and fast and look great. Are most perennials like this?


what about that giant sunflower?

Do perennial seeds grow really quickly and easily?
Perennial seeds mean they can grow from season to season, unlike annuals that only last one year.


You can plant perennials directly into the soil, provided your soil is suitable for growing plant-life. Potted plants are more expensive because some nurtured their growth, etc. Also, the gardner is working with an established plant versus the process of sowing and nurturing the seeds.


Perennial plants are all sizes and shapes. Cacti are perennial and azaleas are perennial. Zinnias are wonderful plants too. I have one area in my garden where I let zinnias grow naturally from year to year. I've grown sunflowers, and they do grow fast considering their size. I've used the seeds to feed birds, and if you don't pick them - the birds will help themselves!
Reply:It depends upon the perennial.





Usually, perennial (or biennial) seed grown plants do not gain the height or bushiness of a mature perennial or biennial plant that first growing season. Example: I don't think oriental poppies look good (leaf-wise) until the second or third year.





Giant sunflowers (annuals) grow quickly once they get going in the spring and summer.
Reply:seeds grow at different rates just like we do.it all depends on the temperature you keep them at to start with and how much daylight they get. if you don't have anywhere outside warm enough try putting the seed tray in a clear polythene bag , make sure they are moist first,on a window sill or near a radiator. but not to hot or they will shoot up to quickly .
