Coleus are beautiful, colorful and fast-growing plants that also happen to be easy to germinate! There are a few varieties out there to pick from, we love Rainbow Coleus, Black Dragon Coleus and Wizard Coleus.

To grow coleus from seed, start by planting the seeds in a well-draining potting mix. Keep the soil consistently moist but not waterlogged and cover with a humidity dome. Place the pot in a warm spot with bright, indirect light(a windowsill with filtered sun or a grow light) and watch as the seeds germinate within a few days and grow into vibrant, colorful plants.

Coleus plants thrive in bright, indirect light indoors or in shaded gardens outdoors and should be watered when the top inch of soil feels dry.

2. Polka Dot Plants

Hypoestes 'Polka Dot Plant' Seeds - Plantflix

Polka dot plants(Hypoestes) are known for their colorful foliage and easy care requirements. There are 3 main colors of polka dot plants out there: Pink, White and Red, each sport that characteristic speckled foliage with their respective color!

To grow polka dot plants from seed, sow the seeds on the surface of moist soil and cover lightly with a thin layer of soil, and top with a humidity dome. Keep the soil consistently moist, keep the setup warm(>70F) and provide bright, indirect light and you should see sprouts within 7-14 days!

Once the plants start to grow and have a few leaves, pinch back the stems to encourage bushier growth. If you notice the plants produce foliage with more green and less spots, you may need to provide them with more light. If the leaves start to curl, that usually means they need some more water. As long as they have good light, soil and water, polka dot plants grow quickly into lovely and cheerful houseplants!

Chlorophytum amaniense, also known as the Fire Flash Plant, is a cousin to the popular Spider Plant. The seeds can be a little trickier and take some more time to germinate, but with the right setup, the seeds germinate readily and grow relatively quickly once they do!

To grow fire flash plant seeds, plant the seeds in a well-draining potting mix and keep the soil evenly moist. Make sure to cover the seeds with a humidity dome to ensure good germination rates, keep them warm, and place them in a spot with bright, indirect light or a grow light.

Once the seeds sprout, just make sure the seedlings have good access to light and water and you'll find the seedlings grow quickly and start producing their signature orange stem coloration in a few weeks! As plants, fire flash plants are easy to care for and can thrive in a variety of conditions, the key things are making sure they have enough light and space to grow.
