Blacknight’s single, romantic blooms create a truly stunning statement in the summer months.

Everybody loves Hollyhocks--tall beauties that create tremendous color wherever they grow. They quickly create spires of flowers up to 5 or 6 feet.

These old-fashioned plants are famous for being biennial which means they bloom their second year from seed. But ours are already in their second season, so they're guaranteed to bloom this coming summer.

Hollyhocks are great for the back of the border, and also as a blooming screen for unsightly views or other things you'd like to hide with beautiful flowers all summer long.
