Planting Permanence: Top Perennial Growing Advice
Perennials are sought-after garden plants, and for good reason. In contrast to annuals, perennials return year after year so the work you put into getting them started and established in year one is an investment with many returns!
Despite this benefit, most people purchase their perennials as transplants. While it's true that some perennials require more complicated seed starting conditions, other perennials are fairly easy to grow or just take some know-how and patience. We've broken down our catalog of perennials so that you can save on plants and time and enjoy long-lasting perennials grown from seed.

Top Ten Tips for Starting Trickier Perennial Seeds
Now that we've covered the easiest to grow perennials, its time to cover those that have their own set of care instructions. Check out our top tips, and the plants that need them below.
- Cold stratify: Many perennial seeds need to go through winter-like conditions before germinating. Generally, you can stratify seeds by placing them in a moist towel in the refrigerator for 6-8 weeks. Or, seed into flats, water them in, and keep in a cold place for several weeks before bringing them back into a warm environment for germination.
- Give light: Because they germinate on the surface in their natural habitat, some varieties need light to germinate. Check the seed packet for germination light requirement. If light is needed, rough up the surface of your seed-starting pot with your fingers and sprinkle the seeds directly on top.
- Nick & soak seeds: Some seeds have a hard seed coat to protect them from adverse conditions. In a tended garden environment, this can make it tough for seeds to germinate. Some seeds need you to rough them up a bit. Soak seeds overnight in warm water, then nick the seed with a razor blade before sowing.
