Penstemons: Summer's Favorite Flowers
Looking for a long-blooming, low maintenance perennial?Penstemons are at the top of their game when it comes to summer blooms! These foxglove-like wildflowers will fill your garden with different shapes and colors! These blooms will be sure to create a hummingbird and bee-friendly garden!
While Planting Keep in Mind:
Penstemons are not as drought tolerant as cactus but will thrive in desert-like climates. Your seed will do best in well-drained soil. This will include any soils that include sand and gravel. However, you can work around poorly draining soil by planting your seeds on sloped areas.
Blooms with a purple or reddish color will do best when grown in direct sunlight. However, all Penstemons will grow in full sun to part shade.
After flowering is complete, pruning your penstemons will promote new foliage grown for a second flush of blooms. Just make sure that you leave some seed heads for your plant to reseed. Although they are deer and rabbit resistant, they may still be bothered by slugs, snails and spider mites.
