Growing Old Fashion Heirloom Pentas ‘Starburst’ in the Northeast Florida Landscape
Pentas Old Fashion Heirloom ‘Starburst’ Origins:
While Pentas lanceolata are native to the tropical regions of Africa they are a Florida friendly landscape plant and an excellent addition to any landscape.
‘Starburst’ pentas origins are unknown to me. The older tall pentas have become scarce in the horticulture market as most of the demand for flowers is for bedding plant style flowers for the front of a bed or border or subdivision entry way etc. This soft pink one that here in Florida is sold commercially under thr name Starburst has little information available on it around but Ive been growing it for seemingly forever. It could be like the Jessica where it was a naturally occurring sport of pentas lanceolata or possibly a seedling variation I just have no idea as there is not a patent for it that I am able to find. For me in my home garden it is like the hot pink Jessica and the Ruby in stature, flower, and garden reliability.
I do find them to be equally as hardy as the ruby red and consider them a hardy perennial for our area expecting to get a few years out of them before I need to replace or replant. Additionally I really don’t see any noticeable reduction in the amount of butterfly visitors I get from one to another. I purposefully planted a group of three Ruby red, a group of three hot pink Jessica and a group of three soft pink Starburst in the same bed in my butterfly garden at home to see if the butterflies tended to favor one and not another only to happily see the butterflies fluttering about between colors seemingly uncaring. The plant clusters were each set at 10ft apart so there was space to note special interest but I just didn’t see it. At work they do noticeably go to the red more often but I think it may be just that I grow a larger swath of the red as it is a customer favorite ( mostly in part to the 5 or 6 butterflies always fluttering about on them at any given time of the day ) so its a bigger attraction from afar. That is not any science but its my own observation trial and that’s all I’ve got! It SEEMS that the larger swath of plants attracts more butterflies…but there is more plants there so…does it not balances out? I think so, maybe.
Pentas Old Fashion Heirloom ‘Starburst’ Preferred Exposure:
– Pentas will prefer a full sun or partial shade partial sun location. Morning shade with afternoon sun or morning sun with afternoon shade both seem to preform well for me here in our St. Augustine Florida area.
Pentas Old Fashion Heirloom Starburst Foliage:
Dark green herbaceous leaves will go dormant for the winter season after fall flowering is complete if we have a cooler winter where the temperatures drop to under 32 degrees for more than just an hour or two in the early morning. If we have a mild winter these plants may just keep on going right through Christmas and into new years remaining evergreen until spring like they do in Central and South Florida landscapes. Normally areas of Jacksonville like the North side, West side etc. will get enough cold to get them some frost damage during the winter months. Don’t toss them out, leave the burnt looking foliage on till spring as they will regrow quickly when the temperatures rise. Just trim off the damaged stems and leaves after all danger of frost has passed and give them some additional nutrition like a shovel full of compost or some slow release fertilizer like Osmocote mixed with Milorganite or chicken manure. ( A little mulch or straw over the base of the plant in the winter season will protect those lower stems and roots from frost damage and have this plant looking great FAST the following spring!)
Pentas Old Fashion Heirloom Starburst Soil Preference / Salt tolerance:
– Heirloom Pentas is not particular about the components of the soil it is planted in providing they are planted in a well draining location.

Love the Idea of Pentas in your home garden but want something shorter, maybe knee high?
Try the Butterfly Series Pentas
or try ‘Orchid Illusion’ Pentas
Want something shorter than that? Maybe shin high? ok but keep in mind these may be more like annuals in the landscape, in all that dwarf breeding they lost a bit of hardiness, but they still come back on warmer winter years and are still a great plant!
Try the Grafitti Series Pentas
or how about just boot high and not quite the range of colors that the Graffiti series boasts but my favorite for containers…
try the BeeBright Series Pentas
