Plant of the Week: Confederate Star Jasmine
You already know Asian jasmine, the groundcover. And those of you in South Texas know its less cold-tolerant sister, Confederate star jasmine (Trachelospermum jasminoides). But in case you don’t, let me share its details.
• Winter-hardy to Zone 8. Great in South Texas. You’ll see it north of Tyler/Waco/Hill Country line, but it has frozen almost every time I’ve tried it in rural Collin County (DFW area).
• Variety ‘Madison’ is reported to be slightly more winter-hardy, but not enough for me in our landscape.
• Evergreen, twining vine growing to 15 to 18 feet tall.
• Does best given a trellis or fence for support.
• Can be grown as a tall, somewhat informal groundcover to 16 to 24 inches.
• Can be grown on a trellis in large patio pot and protected during sub-freezing weather, either in greenhouse or sunroom.
• Slightly larger leaves than Asian jasmine and more open growth habit.
• Good in sun or part shade.
• Blooms heavily in late March in South Texas and through mid- or late April farther north.
• Propagated by cuttings, but it’s easiest to get new plants as 1-gallon pots in nursery in spring.
