4'H or Larger Perennials

Huge flat clusters, becoming dome-shaped as they mature, are composed of numerous small lightly fragrant white flowers that are followed by heavy crops of shiny black berries. The American Elderberry, Sambucus nigra ssp. canadensis, is a large growing native deciduous suckering shrub whose cooked fruit and flowers are used to create healthy and delicious confections, syrup, jelly, wine and more. The nectar rich flower clusters attract an array of pollinators and its ripe fruit is sure to attract a host of bird species. Elderberries are monoecious, both male and female at the same time, and are typically at least semi-self fertile but it is generally recommended to plant at least two different plants for cross pollination and the heaviest crops. If you order multiple plants from us, you will receive at least two different selections. The large ripe fruit clusters are a great treat for chickens. The flowers appear to be most fragrant in the evening and likely at night as well suggesting at least some moth pollination. Item #11269

One of the hottest new native grasses on the market! Blackhawks Big Bluestem starts off in spring as a deep green clump of upright to arching blades that may be tipped with red to purple. It is in late summer when the real show begins with the upright and arching foliage and flowering stems of August deepen to red to red-purple and further deepening and intensifying as the cooler fall weather arrives becoming nearly all black as its sturdy and showy flowering stems begin to mature. Blackhawks Big Bluestem is a slightly more compact plant reaching about 4-5' high when in flower. The species is native throughout much of the eastern 2/3's of the US and is a clumping to slowly spreading rhizomatous grass whose seeds are utilized by a number of seed eating birds. Provide a full to mostly sunny site with an average to well-drained, acidic soil for the deepest foliage colors and optimum vigor. Plants are in their best form when grown in a low fertility soil.

From spring to fall the Blue Butterfly Bush produces large clusters of dainty, blue flowers that very much resemble little butterflies and thus the name. This is a tropical plant that can be grown as a root hardy perennial in the northern portions of its range (zone 9 and warmer) otherwise it makes an easy to grow container plant. In its native habitat it can reach 10-12'H but more typically it is maintained as a 4-6'H shrub. The long canes lend it to use as an espalier. Item# 10681

The Blue Hibiscus, Alyogyne huegelii, is an upright to rounded, naturally evergreen, Australian native shrub that is heat and sunloving and is somewhat drought resistant once well-established. It is fairly adaptable to soil types and moisture as long as they are provided with excellent drainage, otherwise it tends to be fairly short-lived. Full sun is optimal and it can be enjoyed both as a container plant as well as making a nice specimen or informal hedge in the garden and landscape. It is sometimes trained as a tree standard to good effect. Plants tend to be somewhat open and if foliage becomes too sparse or the plants too larger they can be pruned back fairly hard and will put out vigorous new growth and some sources suggest that it flowers best after a good pruning.
