Grow your Own Gladiolus
Gladiolus grows from a large bulb each year, then dies back and regrows the following year. The plant grows a new one right on top of the old one each year. If you want to grow a great number of gladiolus plants and don’t mind spending a few years doing it, gladiolus seed germination is the way to do it. Leave the flowers on the stem for a few weeks after they die back. You’ll find a hard case that is filled with seeds. Sprout these seeds into miniature plants and you’ll have full-sized gladiolus in about three years.
