Today, a few photographs of this persisting bloomer located at the front entrance to UBC Botanical Garden. Ipomoea purpurea 'Star of Yelta' is an introduction from Thompson & Morgan Seeds. T & M describe this cultivar as having half-hardy annual seeds, meaning that in cool temperate climates, it can be sown early in the season once the danger of frost has passed (but before the soil has warmed). In the maritime climate here at UBC, 'Star of Yelta' has persisted from year to year in areas of bare soil without additional seed-sowing by the horticulturists. Given that the parent species has been declared a noxious weed in some jurisdictions (though none in our region) and has naturalized in some pantropical areas, the staff here are monitoring the behaviour of this cultivar. Despite its beauty, it may have to be eradicated if it shows additional indications of potential weediness in our climate.
