Barbara's buttons

Barbara's buttons (Marshallia grandiflora) should be watered about once or twice a week. The soil should be kept moist but not overly saturated. Since these plants prefer a moist environment, be sure to water any time the soil looks dry to the touch. In hot, dry areas the plant may need to be watered more frequently than in cooler climates. During the hottest summer months of July and August, water the Barbara's buttons more often - approximately 2 to 3 times a week - to make sure the soil does not dry out completely.

Barbara's buttons (Marshallia grandiflora) prefer to receive 8-10 hours of direct sunlight per day. In, areas of full sun, the plants may visibly respond to the bright light by growing more upright and rapidly producing more flowers. While it prefers full sun, it is also quite tolerant of part-shade and will tolerate bright, filtered light all day. If it is located in an area that receives too much shade, the plant may produce fewer flowers and its foliage may become sparse. It is best to provide your Barbara's buttons with partial shade during the hottest parts of the day (generally around noon).

Barbara's buttons (Marshallia grandiflora) should be pruned lightly in the early spring. Pruning should focus on removing any dead, dried, or damaged stems or leaves, as well as any errant branches that are crowding the center or that have crossed 1 another. Barbara's buttons may also need pruning to maintain its desired shape and size, but should be done sparingly. It is not necessary to prune Barbara's buttons every year, only when needed.
