16 Easy To Grow Perennial Flower Seeds If You Don't Have A Green Thumb

It's common for many flowering perennials to be propagated using vegetative methods, such as cuttings or division. But, if you don't have a green thumb, you might find these methods a little daunting. Lucky for you, many perennials can also be successfully grown from seeds; growing from seed is not that difficult when you know how. To grow some lovely perennial flowers from seeds, you only need small pots or seedling trays and a good seed-raising mix to fill them with. If you're a new gardener and haven't developed your green thumb yet, buying a commercial seed-raising mix rather than making your own is a smart idea.

So, it's much easier, when you're just starting out, to sow your seeds into pots and then transplant the perennials into the garden once they're large enough. Not all perennials are easy to grow from seed, though. That's why we've selected 16 varieties you should succeed with.
