Best Terrarium Plants: Top Picks for Your Open or Closed Terrarium Setup

1. Why do peace lilies don’t bloom sometimes?
A: If your peace lily plant isn’t producing flowers, it may not be getting enough light. Peace lilies prefer bright, indirect light rather than low light if you want blooms. Try moving the plant closer to a bright window but avoid direct sunlight, which can scorch the leaves. Feeding during the growing season with a balanced houseplant fertilizer can also help keep your peace lily blooming.
2. What is the best watering schedule for peace lilies?
A: To water your peace lily correctly, wait until the top inch of soil feels dry before watering. In warmer months, your watering schedule may be once a week, while in cooler months it’s less frequent. Always use a pot with drainage holes and empty the saucer after watering to prevent the plant from sitting in water, which can cause root rot.
3. Can peace lilies grow indoors in low light?
A: Yes, peace lilies thrive indoors and are considered an easy plant to grow, even in low light. However, blooms may be fewer. For a beautiful peace lily with more flowers, place it where it gets bright light but avoid direct sunlight to keep the large leaves healthy.
Q: How do I start an indoor garden in a small space?
A: Start small by choosing easy-to-grow potted plants or herbs that thrive indoors. Use vertical space with shelves or hanging plants to maximize floor space. For limited areas like apartments or home offices, compact container gardening works best.
Q: What are the best plants to grow indoors?
A: Low-maintenance plants like peace lilies, rubber plants, trailing plants like pothos, and indoor trees such as the fiddle leaf fig are among the best indoor options. They adapt well to indirect light and are easy to care for.
Q: What are the easiest herbs to grow indoors?
A: Herbs like basil, mint, parsley, and thyme are some of the best herbs to grow indoors. They grow well on sunny windowsills or under LED grow lights, especially during the winter months when natural light is limited.
Q: Can I grow vegetables indoors?
A: Yes, indoor vegetable gardening is possible with the right setup. Leafy greens, cherry tomatoes, and radishes are great vegetables to grow indoors. Use containers with drainage holes, provide enough light (natural or LED grow lights), and water when the soil feels dry to avoid root rot.
Q: What’s the best lighting for growing plants indoors?
A: Plants that are easy to grow still need adequate lighting. If your space lacks natural light, using grow lights (especially LED grow lights) can mimic sunlight, ensuring gardening success even during darker seasons.
Q: Can I grow annual flowers in a purple garden alongside perennials?
A: Absolutely, mixing annual flowers with purple perennials adds variety and color through different seasons. Include petunias, morning glories (with trumpet-shaped flowers), or ageratum as bedding plants for summer color, while perennial favorites like garden phlox and purple coneflower return each year for flowers to grow over time.
Q: What are some purple flowers that bloom early in spring?
A: Some of the flowers from spring such as purple bulbs or tubers—think Iris (violet and blue-purple blooms) or early-blooming lavender-blue flowers—offer an early purple color kick. These types of purple flowers are one of the first flowers to appear and help set the tone for your spring garden.
Q: Which purple flowers are excellent for cut flower arrangements?
A: If you’re looking for excellent cut flowers, consider purple coneflower, garden phlox, lavender with purple flower spikes, or deep purple flowers like Allium. These varieties have sturdy stems, vibrant flower clusters, and lasting flower heads that hold up well in bouquets.
Q: How can I use purple foliage to enhance a garden's color palette?
A: Pair purple foliage plants such as Heuchera with green foliage for dramatic effect. Use them alongside plants with purple flowers or violet flowers so that the foliage complements the bloom colors. This contrast brings out richer tones in the flowers and helps the purple garden feel lush and cohesive.
Q: What purple flowers bloom late in the season?
A: For flowers from late summer to fall, Liatris, purple coneflower, and Verbena bonariensis offer long-lasting blooms and violet-blue flowers. These perennial flowers keep your garden vibrant well after the early bloomers fade, extending the season of interest.

FAQs
Q: Can succulents thrive in terrariums?
A: Succulents can thrive in open terrariums but are generally not ideal for closed terrariums. Open terrariums provide the airflow and drier environment that succulents need to prevent root rot and overhydration. Closed terrariums, with their high humidity and limited ventilation, create conditions that are too moist for most succulents to survive.
Q: Can I use cuttings to start a terrarium?
Absolutely! Using cuttings to start a terrarium is one of the best ways to grow plants in a small, contained environment. Many plants, like Pothos and Peperomia, are great for this because they root easily. You can simply snip off a healthy stem, place it in water for a while, and then add it to your terrarium once it's rooted. It’s a fun, cost-effective way to propagate your favorite houseplants, and it helps your terrarium flourish without having to buy a new plant every time!
Q: Can I grow cactus in a terrarium?
Cacti can be a bit tricky when it comes to terrariums because they prefer dry, well-ventilated spaces, which can be tough to achieve in a closed container. While they thrive in open terrariums with lots of light and airflow, you’ll want to be mindful of humidity. Too much moisture in the air can cause them to rot. If you love the look of miniature cacti, just be sure to pick a terrarium with plenty of ventilation and avoid over-watering.
