does anyone know if columbines bloom all summer or just in the spring?
Answers:
Aquilegia (available in more than 30 varieties)
This delicate but hardy perennial flowers from spring to early summer and lasts all sumer long. Plants flower for up to five years.
* Leaves both basal and alternate on the stem, 1-3 times compound, with each division in threes. Those at base and on lower stem are large (to l' long) with long primary and secondary stalks, but become much reduced upward. The small leaflets, in threes, are more or less oval with rounded lobes.
* An old-fashioned garden plant, cultivated in Europe and America since the mid-1600s.
* Native Americans used infusions from different parts of the plant for a variety of ailments from heart trouble to fever and even as a wash for poison-ivy.
* When pulverized, the seeds, a commodity of intertribal commerce, were rubbed on the hands by men as a love charm and also used in some tribes as a man's perfume.
* Reproduction from seed; no vegetative reproduction has been reported.
* The five erect, long-beaked fruits are dry pods, which split along the inner side to shed numerous, shiny black seeds.
* Pollinated by nectar feeding visitors and bees visiting for the pollen. The flower is adapted to prevent self-pollination. Stamens mature first, starting from the outside ring and moving toward the center, shedding all their pollen before the styles emerge at the mouth of the flower and spread their feathery stigmas to receive pollen. Even if the male and female phases overlap briefly, pollen cannot fall upward from the longer stamens onto the shorter styles in the hanging flowers.
* Easy to grow from seeds or from divisions of rootstocks in the spring.
* Sow seeds from spring to early summer or in flats during winter for transplanting outdoors in spring. Newly ripened seeds will germinate without treatment if sown outdoors in seedbeds or flats. Nursery stock should be set out in the spring or in the fall when dormant.
* Seeds need to be exposed to a certain amount of sunlight before they will germinate.
* Seedlings do not flower the first season.
* Hardy to USDA Zone 2 (average minimum annual temperature -50ºF)
* Cultural Requirements
o Light: does best in light shade or with a few hours of direct sun but will tolerate full sun if daytime temperatures are not too hot.
o Soil: well drained, loose, slightly acid, sandy loam with organic matter, but will grow in a wide range of soils, including clays, especially if they drain well and have organic matter added.
o Water: moist
* Several cultivars are available.
* Cultivars and species available by mail order from specialty suppliers or at local nurseries
* Naturally occurs in moist, rocky soil in partial shade, but readily adapts to most garden conditions.
* Plants are short-lived, 3-5 years at best, but self-sow freely, new plants spreading rapidly in the garden. They cross readily; if you want seedlings to be like their parents, plant only one species. If growing multiple species, keep them as far apart, but expect some crossbreeding.
* You can sow any kind of columbine seed now for flowers next summer. Scatter seed in a place that gets filtered sunlight (in woodland edges and under trees, for example). The soil should have good drainage but contain enough organic matter to keep moisture around plant roots at bloom time.
