Sweet William hardy perennials

Sweet William hardy perennialsSweet William are well-known hardy perennials, and deservedly favourite border plants, which may be grown in any good soil; but to have them to perfection they should be placed in light, loamy ground mixed with a little old manure and sand.

They can be raised with little trouble from seed sown thinly at any time between March and midsummer where they are to bloom, and may also be increased by dividing the old plants in spring.

Sweet Williams produce their flowers in July and their height is about 1.5 feet.
