Answer: Unfortunately, both the spikes and the variegated vinca are usually started on a wholesale commercial basis because they need warm temperatures and a greenhouse environment to root and grow well. You can however start your own cuttings of the vinca each fall and overwinter them as a houseplant. The spikes (actually a cordyline despite what we call them) can also be overwintered as a houseplant. The evergreen and very cold hardy vinca minor (periwinkle) is available as bare root plants from Burpee (www.burpee.com or 1-800-888-1447), although it is more often used as a groundcover than in planters.
