Blue cupflower, also known as nierembergia (Nierembergia hippomanica) delights with its tiny, yet very numerous blooms. Single, blue flowers wilt quickly, but the next waves of them develop in large numbers every day all summer long. This plant forms slightly crawling habit of strongly branched shoots. Nierembergia fits onto lower borders, into rock gardens and alongside walls and border edgings. They would look great in hanging baskets and boxes, where their shoots could hang freely, creating exceptionally beautiful ornaments on balconies and terraces.

Early spring is the perfect time for sowing seeds. Sow them to boxes filled with light and permeable soil, but do not cover. It is important the seedling production takes place in a warm and sunny place, because the seeds would germinate only with access to light. Nierembergia is rather undemanding and it would grow in every kind of permeable soil, but it prefers fertile and moist soils. It likes sunny spots, but may need watering during especially hot summers.
