Pentas is one of the best butterfly-attracting plants around. It blooms all summer long, even during the hottest weather, with large clusters of starry blooms that attract butterflies by the dozens as well as hummingbirds. The plant grows well in containers and in the ground — and it can even make a good houseplant if you have enough light. It does best in full sun and moist, well-drained soil. Pentas is grown as an annual in most parts of the country, but it’s hardy in Zones 10-11. Plant it outdoors after all danger of frost has passed.
From tiny, cheerful Johnny jump-ups to the stunning 3-inch blooms of Majestic Giant pansies, the genus Viola has a spectacular array of delightful plants for the spring garden. They’re must-haves to celebrate the first days of spring since they don’t mind cold weather and can even take a little snow and ice!They’re pretty planted in masses in the ground, but also cherished for the early color they bring to pots, window boxes, and other containers. By summer, pansies bloom less and their foliage starts to brown. It’s at this time that you’ll have to be tough and tear them out and replant with warm-season annuals, such as marigolds or petunias. But that’s part of their charm — they are an ephemeral celebration of spring!
