Pinkflower Chineses Indigo

Pinkflower Chineses Indigo

This deciduous shrub grows well in our area. It bears erect racemes of pea-like, pink flowers from summer to early fall above leaves composed of several leaflets. The flowers are followed by long, dark purple seed pods. In colder climates this shrub may die back to the ground, resprouting from the base in spring. Provide full sun and moist, well-drained soil in USDA Hardiness Zones 6 to 9. Prune out wayward and crossing branches in spring.

You can find this plant in our Fountain Garden.(2016)



Would you like some color in your garden? It's easy with Garvinea...Garvinea is a revolutionary new gerbera with a unique combination of features. Using genetics from wild South African plants, breeders have managed to come up with a color palette of strong, prolific, free flowering gerberas which have cold tolerance and superior pest and disease resistance.

Garvinea are happy in full sun to part shade and look gorgeous mass planted in garden beds and large containers. What Garvinea lacks in flower size compared to other gerberas is more than made up for by the quantity of flowers, with each plant yielding well over 70 blooms per year. They provide continuous color from spring right through summer to the end of autumn. Garvinea are winter hardy and survive where temperatures may drop to -5C. Come spring the flowers will start popping up for another long season. Being pest and disease tolerant means that Garvinea are much easier to grow than most other gerberas.

You can find Garvinea on the sunny side of the Entry Garden above the driveway test beds.(2016)

Virginia Sweetspire

Virginia Sweetspire

This old time favorite native plant for southern landscapes has been used for generations because of its seasonal beauty, hardiness, durability and resistance to disease and insect pests. Virginia Sweetspire has many notable characteristics - gorgeous white, slightly fragrant flowers that show up in late April to May and superb fall color.

It is tolerant of wet soils, yet amazingly it has very good drought tolerance. When placed in full sun the foliage gets denser and the flowers are more abundant.

Flowers are formed on the previous season's wood so we should always wait until after flowering to prune. In the fall, the leaves change to burgundy-purple which presents an attractive contrast to broadleaf evergreens in the landscape.

Plant them en masse for best effect - if given adequate sunlight and moisture they will supply many years of enjoyment.

You can find sweetspire in the Herb Garden, Boulder Garden, and other places throughout the Linnaeus Garden. (2016)
