In 2017, I was a little risky to try some new plants, especially the tropical and vibrant kinds. So here is a list of plants I grew in 2017 that I will grow again in 2018.
Passionflower (all varieties) - Passiflora sp.
Unicorn Rush - Juncus effusus
This tiny, spiraling, grasslike, marginal water plant is intriguing. It blends well with the water lilies and irises in a pond. It goes in a pot on the sides of the pond, and it is marginally hardy. 7a is probably the safe zone.
Tropical Waterlily (all varieties) - Nymphaea sp.
