Ending the last week of National Perennial Month with Alcea Rosea - Hollyhock. This time tested garden favorite may be considered a short lived perennial but can last for many years if cut down to the base after flowers fade. Growing 5'-9", Hollyhock makes an excellent screening plant. This beauty is very easy to grow in full sun with blooms starting mid-summer and going through early fall. Planting Hollyhock can be done in the spring or fall in almost any soil making this a very tolerant perennial. You can't go wrong with this tall beauty in your garden. Best if propagated by seed, plant seedlings two years in a row so you'll have lots of plants every year.
