At the butterfly garden where I work, I get asked pretty much every day which nectar flowers are best for butterflies. There are many ways to define “best”, of course, but what most of my guests are looking for is a plant that’s easy to grow, easy to find at plant nurseries, and attractive to both people and butterflies. There are a few plants that fit this bill very well, and at the top of the list is Pentas lanceolata, known more commonly as Penta or Starflower.
In most of the country, pentas are grown as an annual, though you can overwinter them in zones without frost. They’re readily available in nurseries in most areas, and very easy to grow. The clusters of tiny star-shaped flowers are laden with nectar, and butterflies of all sizes love to visit them. Though pentas are not native (they come from Africa and Arabia), I don’t know of any place in the U.S. where they’re considered invasive, since the cultivated versions sold here rarely re-seed themselves. Seed is available from catalogs and online, but the germination and seedling growing process can be difficult, so you’re better off just buying nice bedding plants from your local nursery.
Growing Tips:
- Pentas are available in traditional and dwarf varieties. The traditional varieties can reach 2 – 3 feet in height and get a little sprawling, while dwarf varieties stay compact and top out around 12 – 15 inches. Read tags carefully and choose the variety best for your location.
- Pentas are fairly easy to grow, but do require regular deadheading to look their best and flower well.
- Grow pentas in full to part sun, and provide regular water especially as they establish. They grow well both in the ground and in containers.
- You’ll find pentas in reds, pinks, purples, and white. All shades are attractive to butterflies, though many report that red is the most popular, and is also known to attract hummingbirds.

I love the look of the Pentas. Not sure that red would go with my current landscaping colors, but white or purple would! I’d love to attract some buttterflies to our yard, the kids would get a kick out of it too! Glad to hear that they are easy to grow. The easier the better. 🙂

I have a very fragrant bush in my backyard when in bloom has pale pick flowers on it. The butterflies and bees LOVE it, so much so that after it blooms, I am loathe to cut it back because some of the flowers last for a very long time and I don’t want to remove a food source for the butterflies and bees.

I saw a hummingbird choose to feed from my red pentas this morning instead of my feeder!

I didn’t know these would attract butterflies and humming and got a delightful surprise when both showed up one day! But I am a beginner gardener and was curious to know if I can somehow save pentas throughout winter for next year. I don’t quite understand annuals/ perennials, and I already planted these pentas outdoors inns the ground :/. Or maybe they will hibernate and grow back after the frost? Please help. I don’t know what I’m doing

Pentas will only survive winter in grow zones 10-11. However, if you dig them up before first frost and bring them in, you can keep them through winter. I had 2 of 3 survive last winter in my basement where they had very little light. Granted they were looking pretty bad by the end of winter, but they came back quickly once outside. If you can put them near a window they should be fine.

My Ruby-throated Hummingbird loves the hot pink Pentas I have beneath the tree where the sugar water is!
Dee says
We have the pink penta in our garden. Just bought the white one – main goal is to attract the hummingbirds! Looking forward to take more pictures!

I planted Passion Flower to cover a fence in my yard. It took off and covered the whole thing within a year (about 40 feet untrimmed). This year I am still amazed. Butterflies and their offspring galore! Never less than 6-8 Butterflies at a time and the honey bees love the flowers too!
Karen says
All butterflies love pentas! They come in all colors and are inexpensive and easy to grow!!!!!

One caveat regarding the newer, more compact pentas cultivars, is that most of them are terrible as nectar plants as compared to their heirloom ancestors.
Breeders looking for larger flower heads sitting atop compact plants have regrettably also bred out the copious nectar production these plants are famous for. Heirloom varieties are the best, although they can grow tall and lanky and may need support. Unfortunately, they’re very hard to find, at least in my neck of the woods.
Enter the ‘Butterfly’ series of compact pentas. They are both floriferous and compact, plus they’ve retained the nectar production of heirlooms.
