Typically, hollyhocks are known as biennial plants, meaning they complete their life cycle in two years. However, with a few pro tips, you can actually keep these beauties coming back year after year. If you want to enjoy those towering blooms for the long haul, here’s what you need to know.
How Hollyhocks Can Become Perennial
If you notice a hollyhock popping up in the same spot in your garden year after year, but the flowers are suddenly a different color, you’re likely looking at natural reseeding. The original plant dropped its seeds, and new ones took its place. This is a great, low-effort way to keep your garden looking lush for years.
The reason the colors might change is that hollyhocks don’t always grow “true to seed.” You never quite know which traits the parent plant will pass down to the next generation! If you want a plant that truly lives for several seasons itself, look for heirloom varieties. These older types are much more likely to behave like true perennials, giving you several years of growth from a single plant. Just be sure to pick varieties known for their longevity when you’re shopping for seeds.
Tips to Extend Your Flowers’ Lifespan
You can actually “trick” your hollyhocks into living longer with a little strategic pruning. The secret is to grab your garden shears at just the right time. To encourage the plant to return next year, you’ll want to cut it back right after the blooming season ends. This helps the plant focus its energy on root health and survival rather than seed production.
Quick Tips for Pruning:
- Always use a sharp pair of shears.
- Disinfect your blades before you start to prevent spreading disease.
- Pick a dry, clear day to do your trimming.
When you cut back the stalks, you’re removing the fading flowers before they can develop seeds. While this means you won’t get “volunteers” from dropped seeds, it significantly boosts the chances of the original plant returning with gorgeous blooms next summer. It’s a tiny bit of garden maintenance that goes a long way!
