Often found in cottage gardens, hollyhock’s (Alcea rosea) bloom all summer long in single and double clusters (depending on how they are cultivated), featuring the hues lavender, pink, purple, red, salmon, apricot, and yellow. Not only will the biennial flowers encourage hummingbirds to visit, but butterflies like them, too. Plus, the Hollyhock will reseed itself in your garden, ensuring that its pretty colors will come again and again, according to HGTV.
The easy-to-grow flower likes a warm, sunny spot in your garden. You should plant them in the spring and fall — although if your winters are rough, plan your gardening for the warmer season.
