Other Beautiful Skullcap Varieties
Heartleaf Skullcap (Scutellaria ovata)
Heartleaf Skullcap is a Texas and North American native plant known for its attractive heart-shaped leaves and spikes of blue to violet flowers. It performs best in morning sun and afternoon shade with well-drained soil and is an excellent addition to woodland gardens, native plantings, and shaded pollinator habitats. Bees, butterflies, hummingbirds, nighttime pollinating moths, and other nectar-seeking insects are frequent visitors to its nectar-rich blooms.
Heartleaf skullcap grows to an average mature size of 1-2.5′ T x 1-1.5″ W. Deer and rabbits tend to leave it alone as the foliage tastes bitter to them. Its heaviest bloom period is spring – summer, and makes a great foliage plant in the cooler months. Once established, Heartleaf skullcap is fairly drought tolerant.
Dark Violet Skullcap
Dark Violet Skullcap is a well-adapted perennial which offers rich violet-purple flowers that create a striking contrast against its neat green foliage. Like its pink cousin, it blooms over a long season (summer into fall) and thrives in full sun to part shade. It has an excellent drought tolerance once established. An outstanding choice for pollinator gardens, borders, and containers where a deeper flower color is desired.
This compact plant reaches and average mature size of 6″ T x 10-15″ W, so it is a perfect option when you need to tuck extra color into a garden or border. While it can thrive in soil that lacks nutrients, the soil must still be well-draining. Try combining this vibrant violet skullcap with like-minded plants like salvia or coreopsis.
Red Fountains Skullcap
Red Fountains skullcap adds a completely different look to the garden with masses of vibrant red tubular flowers held above attractive foliage. Hummingbirds are especially drawn to the bright blooms, making it an excellent companion for butterfly and pollinator gardens. It thrives in warm climates, enjoys full sun to part shade, and also flowers continuously early summer to early fall with minimal care.
Average mature size is 8-12″ T x 18-24″ W, with spikes of the colorful red blooms atop stems. The plant grows in a mounding form and look great in both the garden and even hanging basket (so they can be at the perfect height for hummingbirds). Red Fountains skullcap is an herbaceous perennial that benefits from an insulative mulch, like pine straw, around it’s crown in winter (but not piled up right next to it). This helps to further ensure it comes back the following year.
Whether you choose the soft pink blooms of Texas Pink skullcap, the dramatic purple flowers of Dark Violet skullcap, the native charm of Heartleaf skullcap, or the hummingbird-attracting Red Fountains skullcap, these easy-care perennials offer months of color with very little maintenance.
Their heat tolerance, drought resistance, deer resistance, and ability to support bees, butterflies, and hummingbirds make skullcaps some of the hardest-working plants in the garden. If you’re looking for reliable color that thrives in the Texas climate, skullcap is a plant you’ll enjoy year after year.
